Pay It Forward

A random act of kindness that I performed this week was that I anonymously paid my friend electric bill.  She has been out of work since December when she slipped on an icy platform and broke her knee and times have been really difficult for the family so I decided to pay her electric bill since that is one bill that she was having difficulty getting help with paying.  She doesn’t know yet that the bill was paid but she will when she calls to try and get a payment arrangement and I know that will relieve some of the stress that she has been under.  I do not plan on telling her that I am the one who paid the bill because I do not want her to feel obligated to pay me back, I just want to help her in any way that I can until things get better for her and her family.
Altruism, Personal and Professional Social Responsibility, and Codependency
Altruism can be defined as “the conscious devotion to helping others regardless of whether the motivation is self-interested or other centered.  It is a premeditated pursuit of charity to unify and increase the overall welfare of society” (Wasieleski, 2008).  In contrast to Altruism, professional social responsibility is doing things that benefit society and not just individuals.  Codependency is “a psychological syndrome noted in partners or relatives of persons with alcohol or drug addiction that includes low self-esteem and a unreasonably high need for approval and affection, and denial---both of their own personal needs and of problems within the family” ("codependency," 2014).   Many people believe that acts of altruism are rare; however I disagree because I have witnessed as well as performed altruistic deeds because it was something that needed to be done at the time.  Professional social responsibility is very common; although it may not always be genuine and codependent actions happen because the individual that is on the opposite side of the receiving end is in need of the mutual relationship with the individual that is receiving the benefits.     
Altruism Application to Psychology or Psychological Principles
The desire to want to help individuals could be considered altruism in psychology, however many individuals that practice psychology may not be doing it for that reason but they do have a professional social responsibility to assist individuals in seeking a better quality of life. Altruism works together with psychological principles because they are intended to alleviate the difficulties that human beings suffer from without any personal agenda or profit.
Altruism Improvement on Human Condition
At one point in time I was experiencing some financial struggles and someone anonymously paid my utility bills which relieved some of the stress I was experiencing, so when I performed the same act for my friend it provided me with a sense of good feelings because I was able to return the deed that was done for me once upon a time.  It is believed that altruism is supposed to provide a benefit for all involved which could turn into individuals consciously being involved in committing acts to pay it forward.  Altruism improves human condition because it allows individuals to help others in need without expecting anything in return and that may give those individuals receiving the help the desire to want to help someone else one day.


Personal and Professional Responsibilities Related to Altruism
Managed health care has prompted many psychological professionals to perform altruistic deeds, such as providing services free of charge to clients whom cannot afford to pay because they are considering the well-being of their clients above everything else. The Pro Bono Counseling Project was developed “to help fill the gap in mental health services to low-income individuals and families” (Bembry, Anderson, & Yaggy, 2002), that are affected by all the changes in medical coverage.
Future of Psychology in Contemporary Society & Altruism
The future of psychology in relation to altruism is dependent upon the professionals whom are practicing and whether or not their acts will be in the best interest of the clients or for personal and/or professional benefits.  Society is definitely in need of individuals who are strong, responsible and have a desire to make changes in the quality of human life, which is why altruism is very important in the field of psychology and contemporary society. 
Conclusion
Random acts of kindness can be considered altruistic deeds and can also be the result of an individual performing professional or social responsibility, which can improve human condition.  Many argue that there is no “true altruism”, however I disagree because there have been situation in which individuals had to immediately take actions to help an individuals in need without thinking about the benefits, such as the man who ran in the burning house to save the children that were trapped on the second floor.

Ethics Awareness Inventory

Ethics deal with questions such as “how should we live?  Shall we aim at happiness or at knowledge, virtue, or the creation of beautiful objects? If we choose happiness, will it be our own or the happiness of all? Can we justify living in opulence while elsewhere in the world people are starving? What are our obligations, if any to the generations of humans who will come after us and to the nonhuman animals with whom we share the planet?” ("ethics," 2014)  Basically, ethics is “the discipline concerned with what is morally good and bad, right and wrong” ("ethics," 2014).  The Williams Institute for Ethics and Management developed the Ethics Awareness Inventory as a “tool for developing ethical competency” (Ethics Awareness Inventory, 2011) in professional settings.  This paper will briefly discuss the results from my Ethical Awareness Inventory as well as the role and importance of personal ethics in psychology, principles, and the code of conduct.  This paper will also discuss how ethics can affect how you apply psychological principles to personal, spiritual, social, and organizational issues and assess how ethics affects psychological knowledge and principles related to personal growth, health and development. In conclusion this paper will analyze advantages of psychology as a degree choice and how ethics play in role in deciding to pursue a degree in psychology.   
Ethics Awareness Inventory
Reading the numeric results from the Ethics Awareness Inventory were a bit confusing because I couldn’t understand what the numbers represent, however further into the results I learned that my ethical perspective is based on the results or consequences of my actions.  The results from my ethical perspective states that I believe “that conduct should be directed toward promoting the greatest good for the greatest number of persons.  In judging whether an individual’s actions are ethical, I look for concrete evidence”. I couldn’t agree more with this perspective because I almost never go by a person’s word but rather their actions. My ethical style is one that believes that “we each have a moral right to experience the good life”.  My focus is typically on the improving the well-being of the people because unhappy people have a negative effect on societies moral which influences ethical behavior.
Importance of Personal Ethics In Psychology
Personal ethics are developed through an individual’s lifespan and are extremely important in psychology because they influence professional ethics.  Professional ethics shape the foundation of professional behavior in psychology and that is why the “APA formed an ethics committee in the 1930s, and developed its first set of ethical principles in 1953” (Plante, 2011 p. 371).  The American Psychological Association developed the ethics code of conduct and ethical principles to protect the well-being of clients by outlining the responsibilities of a psychologist that ensures no harm is done to anyone obtaining services.  The code of conduct outlines what types of behaviors and actions in the field of psychology are acceptable as well as unacceptable.
Effects of Ethical Application
According to the Ethical Awareness Inventory results my increased awareness influences how I will apply psychological principles to personal, spiritual, social, and organizational issues.  I scored high on result-oriented perspectives that are based on the consequences of actions taken; therefore following the ethics code of conduct and principles are extremely likely in all aspects of life because positive results are extremely important.  I am goal-oriented, productive, systematic, and analytical and a global thinker and my main goal is to always do what is good for the people by focusing on getting positive results in any given situation. 
Ethics Effect on Personal Growth, Health, and Development
Lawrence Kohlberg developed a theory on stages of moral development that shows how ethics effect personal growth, health, and development because ethical behavior develops as one advances through the stages.  Personal growth influences ethics because individual’s display responsible behavior through learning new skills and obtaining knowledge.  Personal development causes an individual to grow which changes their attitude in a positive manner.  A positive attitude is good for an individual’s health because it reduces stress.  Ethics boost self-confidence because individuals believe they are more capable of accomplishing certain things which increase development through learning from experience.   
Psychology as a Degree
Pursuing a degree in psychology can open the door to a variety of careers, such as Clinical Psychology, Forensic Psychology, Industrial/Organizational Psychology just to name a few.  A degree in psychology also is an excellent way to learn more about other people as well as yourself because by studying psychology individuals gain a better understanding of human nature such as how and why people think, feel and behave certain ways.  Ethics play a major role in people making the decision to pursue a degree in psychology because most people with strong ethics want to help others and psychology is a field that focus on helping people. 
Conclusion
The Ethics Awareness Inventory is used to assess the personal ethics, principles and moral judgment of an individual in any given situation and the results give an ethical perspective based of the answers provided.  Personal ethics is very important in psychology because they can have a direct influence on professional behavior and that is why the American Psychological Association developed the code of conduct to protect the well-being of clients by ensuring that psychologist do not allow their personal views affect their judgment when providing services. There are many benefits of obtaining a degree in psychology such as multiple career choices, however the most beneficial of all is learning what motivates human behavior.
  

The Diverse Nature of Psychology

Psychology is the scientific study “of the thought processes and behavior of humans and other animals in their interaction with the environment” ("Psychology," 2013).  The field of psychology consist of many different divisions that allow Psychologists the opportunity to “study processes of sense perception, thinking, learning, cognition, emotions, and motivations, personality, abnormal behavior, interactions between individuals, and interactions with the environment” ("Psychology," 2013), which dates back to ancient civilizations of Egypt, Greece, China, and India.  This paper will evaluate the influence of diversity on psychology’s major concepts as well as identify two examples of sub-disciplines and two examples of subtopics within psychology and how these examples can be applied to other disciplines and venues in contemporary society, relate the sub-disciplines and subtopics to a theoretical perspective.
The Influence of Diversity on Major Concepts in Psychology
Diversity has a very strong influence on the major concepts in psychology, such as the psychodynamic, cognitive, behavioral and evolutionary because each concept offers a different explanation on human behavior.  Psychodynamic was developed by Sigmund Freud states that “people’s actions reflect the way thoughts, feelings, and wishes are associated in their minds; that many of these processes are unconscious; and that mental processes can conflict with one another, leading to compromised among competing motives” (Kowalski & Westen, 2011 p. 15).  B.F. Skinner developed the concept on behaviorism that “focuses on learning and studies the way in which environmental events control behavior” (Kowalski & Westen, 2011 p.17). The cognitive concept “focuses on the way people perceive, process, and retrieve information” (Kowalski & Westen, 2011 p.19) and evolutionary states that “many human behavioral tendencies evolved because they helped our ancestors survive and reproduce” (Kowalski & Westen, 2011 p.25).   
Major concepts in psychology were developed though experiments and research on human behavior “and although the different perspectives offer radically different ways of approaching psychology each has made distinctive contributions” (Kowalski & Westen, 2011 p. 28) and have allowed researchers the opportunity to incorporate the findings into different areas of psychology giving psychologists the chance to go in more depth with assessments and diagnosis of individuals seeking treatment for psychological issues. 
Psychology Sub-disciplines and subtopics applications to other disciplines
A sub-discipline can be defined as “a specific area of study within a broader field” (American Psychological Association, 2010) and The American Psychological Association recognizes “four “specialties”-clinical, counseling, school, and industrial/organizational psychology (APA, 1997a)” as cited in (Landrum & Davis, 2010 p.13), however “there are 54 subdivisions of psychology with the American Psychological Association (APA) comprising diverse areas of practice and research” (American Psychological Association, 2010).
Industrial/organizational psychology “apply psychological principles and research methods to the workplace in the interest of improving productivity and the quality of work life” (Landrum & Davis, 2010 p.15).  I/O psychologists work in organizations to help with hiring, training and developing healthy positive working environments. The psychological findings from I/O psychology can be applied in abnormal psychology and clinical psychology to provide information on how the workplace influences behavior that could cause an individual to develop mental illness. 
 Environmental psychology examines “the relation between psychology and the physical environment, including homes, offices, and urban or rural areas” (Landrum & Davis, 2010 p.14).  Environmental psychologists’ main focus is on how things in the environment, such as pollution, noise and traffic congestion affect human behavior and the role human’s contribute to those environmental stressors. Architecture, sociology and education are examples of other disciplines that can benefit from the application of environmental psychology through conducting research and applying those findings to help develop environments that improve human behavior.  
Educational psychology focus is “on the conditions under which effective teaching and learning take place” (Landrum & Davis, 2010 p.14).  An Educational psychologist will examine different aspects, such as “human abilities, student motivation, and the effect on the classroom of the diversity of race, ethnicity, and culture” (Landrum & Davis, 2010 p.14).  The psychological findings in educational psychology can be applied to other disciplines such as cross-cultural psychology to help psychologists gain a better understanding on how individuals from different cultural backgrounds process information during their learning experience. 
Theoretical Perspectives
Psychoanalytical and cognitive-behavioral are two major theoretical perspectives that relate to the sub-disciplines and subtopics that were discussed because they both state exceptional diverse views on mental illness in relation to human behavior.  Psychoanalytic theory “is a framework for understanding the impact of the unconscious on thoughts, feelings, and behavior” ("Psychoanalytic Theory," 2008), whereas cognitive-behavioral theory focus is on “changing the behaviors and cognition's that are thought to be currently maintaining a problem, rather than on helping a client to gain insight into the early developmental factors that may have initially set the stage for developing the problem” (Antony, 2005) like psychoanalytic theory.  The psychoanalytical method is long and tedious because it seeks to bring unconscious suppressed conflicts into consciousness so the issues can be resolved, whereas cognitive-behavioral method is short-term because it is “problem focused and goal driven” (Antony, 2005).  Although both theoretical perspectives are different in their approach they both share a common goal and that is to offer a resolution to improper thoughts and behavior that causes disturbances in human nature.
Conclusion
The diverse nature of psychology has its strengths and weaknesses that continue to evolve because of continuous research efforts that seek to understand human behavior from different viewpoints and perspectives.  Each sub-discipline and subtopic concentrates on specific areas of concerns; however they all seek to explain human behavior just only in that particular setting therefore the incorporation of theoretical perspectives is needed to get a more diverse understanding of certain behaviors.  I practice maintaining good mental health which allows me a greater understanding of diversity that exists within human nature especially where mental health is concerned. My concern and care for the well-being of others without bias gives me a better opportunity to learn more about the influences on human behavior, personalities, mental illness and how one day I could be of more service to those in need.


Examination of Clinical Psychology

The field of psychology focuses on the human mind and behavior to gain understanding of why people think, feel and behave certain ways.  In a continuous effort to gain understanding of human behavior psychologist observe individuals, administer questionnaires that are known as psychological testing and develop theories based off of results from experiments that are conducted.  The field of psychology has many sub-fields that include “human development, health, industry, law, and so on” ("Psychology," 2009).  This paper will examine the sub-field clinical psychology and discuss the history and evolving nature of that branch of psychology.  In addition to the examination of clinical psychology this paper will also explain the role of research and statistics in clinical psychology as well as discuss the differences between clinical psychology and other mental health professions, including social work, psychiatry, and social psychology. 
Clinical psychology is considered a major sub-field of psychology that involves “the scientific application of psychology with the purpose of evaluating, diagnosing, preventing, and treating psychological distress or dysfunctional behavior” ("Clinical psychology," 2009).  The basis of clinical psychology revolves around the notion that individuals have the ability to change therefore “clinical psychology focuses its efforts on the ways in which the human psyche interacts with the physical emotional and social aspects of health and dysfunction” (Plante, 2011 p. 5).  Clinical psychology applies psychological findings in relation to human behavior to help individuals manage issues that have developed due to unpleasant experiences that may occurred in their life.  Examples of issues that clinical psychology help individuals with include but are not limited to severe depression that may occur after a traumatic experience such as divorce or the loss of a loved one.  Substance abuse problems, “addictions, hallucinations, compulsive eating, sexual dysfunction, physical abuse, suicidal impulses and head injuries” (Plante, 2011 p. 6) just to name a few.
The field of clinical psychology concentration is on psychological assessment and treatment.  Psychological assessment “involves the use of intelligence, achievement, personality, and neuropsychological tests as well as clinical observations, to attain a better understanding of the individual’s psychological problem” ("Clinical psychology," 2009).  Psychological treatment happens “through psychotherapy that involves a relationship between a clinical psychologist and a patient, couple, family, or group, where the psychologists employs a series of techniques to relieve psychological distress or otherwise improve coping strategies” ("Clinical psychology," 2009).  Psychoanalysis, Psychodynamic therapy, behavioral therapy, cognitive behavioral therapy and humanistic therapy are different theoretical methods that clinical psychologist employ during treatment.
History
The field of psychology emerged as a science in 1879 when “Wilhelm Wundt, also known as the father of psychology, established the first laboratory dedicated to psychological research at Leipzig University in Germany” ("Psychology," 2009).   Soon after the establishment of the research laboratory, “William James published The Principles of Psychology, which laid the foundation for much of the stud of psychology that followed” ("Psychology," 2009) as well as Wundt’s publication of ‘The principles of Physiological Psychology and Theodor Fechner’s publication of The Elements of Psychophysics” (Plante, 2011).  These publications along with research laboratory prompted the establishment of the American Psychological Association in 1892.  The main agenda in psychology was to realistically measure human behavior through observation to gain an understanding of the connection between the human mind and behavior.
Lightner Witmer established the “first psychology clinic at the University of Pennsylvania in 1896” (Plante, 2011 p.32)  that created the term clinical psychology, however long before that development “several Greek thinkers were pivotal in the early development of integrative approaches to illness, and this, were precursors to a biopsychosocial perspective” (Plante, 2011 p. 33).   Ancient Greeks believed that there was a connection between mind and body in addition to their beliefs that God control health and illness.  Hippocrates was one of the first to provide a physiological explanation of disease and dysfunction by suggesting that disparities in the mixture and quantity of body fluids such as black bile, yellow bile, phlegm, and blood was the cause of quite a few emotions and psychological disturbances, such as sadness, irritability, and anger.
Evolving Nature
The American Psychological Association was reluctant to accept a practical approach to psychology; however that did not stop the field of clinical psychology from evolving into a major contributor to the field of psychology with the help of the “works and writings of Sigmund Freud and his colleagues” (Plante, 2011).  Sigmund Freud expanded on the Greeks notion of the connection between the mind and body in which he “proposed that unconscious conflicts and emotional influences could bring about mental and physical illness” (Plante, 2011).  It took some time before Freud’s work actually had direct influence on clinical psychology, however eventually his ideas on human psychology were substituted for humanism, cognitive-behaviorism, and family system approaches.
Prior to World War II, there was not much efforts put into clinical psychology, however after the war, “clinical psychology was newly supported by government funds and expanded enormously” ("History of clinical psychology," 2004).  Eventually the American Psychological Association began to establish “an official system for accrediting training in clinical psychology” which prompted the Boulder Conference to “set the pattern for such programs, which sought to train scientist practitioners” ("History of clinical psychology," 2004).   
The field of clinical psychology continues to evolve due to changes that occur as research is conducted and results differentiate from previous research as well as “the evolution of Western medicine from a non-scientific endeavor to today’s high-tech standard of practice is traced” (Plante, 2011).   As clinical psychology evolved it bought about changes in psychological assessments that lead to mental health facilities being established and the beginning of psychotropic drugs being used as treatment of abnormal psychology.  Although these developments in the field of clinical psychology provide an alternate to what was considered traditional treatment they did not give a full explanation of the behavior in question therefore prompting for research to be continuous.


The Role of Research and Statistics
Research is the foundation that clinical psychology developed from because “research conducted by psychologists or others in the behavioral sciences provides the basis and direction for all professional activities” (Plante, 2011).  Research programs have been developed to assist psychologist in making a determination on “which assessment or treatment approach might be most effective for a particular clinical problem such as depression, anxiety, eating disorders, or substance abuse problems” (Plante, 2011).  Statistics is also a part of the foundation that clinical psychology developed from because information gathered allows researchers to conclude whether or not it is that information provides significance and is relevant to a larger group of individuals. 
Clinical Psychology as it differs from other fields
Clinical Psychology differs from others fields such as mental health, social work, psychiatry, and social psychology because of the training that is needed and the educational requirements.  Clinical psychologist must complete Ph.D. or Doctor of Psychology program that consists of five years of graduate course work and studies that ends with a dissertations and a completion of one year supervised work in the field.  In addition to the educational requirements a clinical psychologist is required to obtain a license by the state before they can begin practice.  Social workers must have a minimum of a bachelor’s degree, pass a licensing examination and two years of clinical experience that is supervised by a licensed social worker.  Psychiatrist must attend medical school where they are required to study chemistry, physiology, and the science of medicine and also two years of applied clinical training.  After medical school psychiatric residency is also required as a part of continuing training.  Mental health requirements are a bachelors or master’s degree in psychology and clinical experience that they can be obtained on the job.  Social psychology requires a minimum of a master’s degree and typically works in settings where they are making observation on human interactions where they apply the knowledge they have on human behavior with scientific research methods which is similar to clinical psychology but it differs due to clinical psychology requiring that an individual have knowledge and skills with all psychology sub-fields.
Conclusion
The field of psychology emerged as a scientific discipline when the first laboratory was created for psychological research and soon after that clinical psychology emerged as a sub-field adding major contributions to the field of psychology. Several factors have contributed to the evolution of clinical psychology that dates back to the Greeks and Hippocrates theories that have allowed for psychologist to make continuous efforts to improve assessments and treatments of individuals using information gathered from research and statistics.  Clinical psychology differs from other disciplines because it’s focus is on applying the knowledge obtained from other disciplines and research to develop assessments and treatment for individuals. 

Attitude Survey on Bullying

A survey can be defined as “a data-collection methods in which individuals answer specific questions about their behavior, attitudes, beliefs, or emotions” (Mrug, 2010). Surveys are commonly used in several fields such as “social and behavioral sciences, political sciences, public health, and business” (Mrug, 2010).   An attitude survey will assess “attitudes in a target population, for example, attitudes towards consumer products (consumer surveys), evaluations of past experiences with products or services (customer satisfaction surveys), evaluations of policies and institutions (public opinion surveys), or evaluations of the state of the economy (consumer confidence surveys)” (Scholderer, 2011).   Bullying is an existing issue that is of interest to me that I created an attitude survey on. This paper will explain the purpose of the survey I developed as well as discuss the preliminary design issues that I experienced while creating the survey.  This paper will also describe the specific instruction for administering, scoring, and interpreting the attitude survey on bullying.
Purpose of Survey
Bullying is an “intentional harm-doing or harassment that is directed toward vulnerable targets and typically repeated.  Bullying encompasses a wide range of malicious aggressive behaviors, including physical violence, verbal mockery, threats, ostracism, and rumors spread either orally, or by other means of communication, such as the internet” ("bullying," 2014).  Bullying has become an increasing problem with school-aged children that has become a major concern to me because my child had been the victim in school.   The purpose of the survey I created was to assess the attitudes that children have on bullying.  The questions were also designed to assess a child’s perception of bullying as it relates to the school environment.  Assessing the attitudes and perceptions of the students on bullying can give school administration a better understanding of how they children are feeling and can offer guidance as to how to resolve the issues of bullying in school.  Children are supposed to feel safe in school and bullying takes away from that feeling of being safe.  The attitude survey on bullying will pinpoint just how serious the issue is within the school.
Preliminary Design Issues
The target audience for the attitude survey on bullying should be the seventh and eighth grade students because I believe that they are the students that have had the most experience at the school and can give accurate accounts on their feelings towards bullying.  During the last week of school the survey should be handed out during homeroom class.  A significant issue that occurred was the initial plan for the types of questions that I would ask to receive precise and attentive replies, therefore I complied sixteen questions that should take no more than five to ten minutes to complete.  The survey uses the Likert scale to measure attitude with possible answers to questions being “strongly agree, agree, neutral, disagree, or strongly disagree” (Jamieson, 2008).  The survey will be a general measure of the student’s attitudes towards bullying on a five point scale and their experiences at the school which can allow the school to determine how serious the bullying is so they can take the necessary steps to address the issue for the upcoming semester.  A significant issue that occurred was the initial plan for the types of questions that I would ask to receive precise and attentive replies.
Administration, Scoring, and Interpretation
The survey should be administered by school personnel, preferably a guidance counselor because they can explain in more details the purpose of the survey and what they hope to accomplish with the help of the students, however the homeroom teacher could also administer the survey to the students in their homeroom providing the same details because of the unavailability of the guidance counselors in schools.  An aspect of the Likert scale is their directionality, meaning “the categories of response may be increasingly positive or increasing negative” (Jamieson, 2008).  The target of the responses have directionality, which means that a rating of strongly agree will correspond to a more favored attitude against bullying.  In order to have accurate results on scoring it is important that all of the students in the seventh and eighth grade complete the survey.  The scores will be calculated to provide an interpretation of how serious the students perceive bullying at the school.  The score can be interpreted by using a point scale “where 1=strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree” (Jamieson, 2008).  Based on this point scale it can be interpreted that  students whom agree or strongly agree to the questions will produce low scores when could mean that they  may have either experienced being bullied or witnessed someone being bullied therefore prompting those responses which could bring out a negative perception towards bullying at the school.
Conclusion
Attitude surveys are designed to assess how people feel about certain subjects, such as bullying.  Bullying occurs when a person is consistently exposed to “malicious and aggressive” behavior for long periods of time which is increasingly occurring in schools across the country and has become a major concern to parents as well as educational professionals and political officials; however the issues have yet to be addressed properly within the schools.  The survey I created uses the Likert scale method of scoring to assess the attitudes of students in regards to bullying at school.  The purpose of the survey was to help school administration gain a better understanding of how the students feel about bullying and the possible effects that bullying has on the learning environment. 
 

Introduction to Psychological Testing

Psychology is defined as “the scientific study of behavior and the mind” ("Psychology," 2009). As a part of the scientific study of the human mind and behavior psychologist use “systematic, objective methods of observation to study any activity that can be observed, recorder, and measured” ("Psychology," 2009).  As a part of studying the mind and behavior, psychological testing were developed to assist psychologist in reaching some sort of conclusion in regards to human behavior.  In this essay I will summarize the major assumptions and fundamental questions associated with psychological testing.  As a part of my summary I will define the term test, describe the major categories of tests and identify the major uses and users of these tests and I will compare and contrast the concepts of reliability and validity and discuss how they affect the field of psychological testing.
Defining Test
According to the free dictionary by Farlex a test is defined as “a series of questions, problems, or physical responses designed to determine knowledge, intelligence, or ability” (The free dictionary by Farlex, 2014).  The word test was derived from “an old French word, with the earliest recorded use in English being by Chaucer in 1368.  In its origin, it meant a cup used for smelting gold or silver ore, perhaps an apropos reference for some high-stakes testing today” (Hogan, 2007 p. 38).   In general a test is a procedure that can be used to measure specific factors or abilities.  There are various types of test that cover specific areas such as intelligence, medical aptitude, personality and many other areas. 
Major Test Categories
There are five major test categories, mental ability, achievement, personality, interests and attitudes and neuropsychological.  Mental ability test “measures both general intelligence and specific intellectual factors” (Laurent, 2007) that includes an individual’s ability to retain memory, spatial visualization and creative thinking.  Achievement test seeks to measure an individual’s “level of knowledge or skill in a particular domain” (Hogan, 2007 p. 6) such as reading and math.  Personality test “measure abstract personality traits, which vary in their presence on human beings and predispose individuals to certain patterns of thinking, feeling, and behaving” ("Personality test," 2009). Interest and attitude test include vocational interest measures that “help individuals explore job related to their interest” and is commonly used in high school and colleges. In this category there are also measures of attitude towards topics, groups and practices” (Hogan, 2007 p.8).   Neuropsychological test are designed to produce information about an individual’s “central nervous system, especially the brain” (Hogan, 2007 p. 8).  Neuropsychological test are often used in conjunction with other test such as personality and mental abilities.  
Primary Uses and Users of Major Test
There are four separate groups that are considered to be primary users of the five major test categories previously identified that include clinical, educational, personnel, and research.  When major test are for clinical use it can be in the “fields of clinical psychology, counseling, school psychology, and neuropsychology”.  When major test are being used for clinical purposes psychologist are trying to help an individual whom currently has or may have had some type of problem and the purpose of the test is to “help identify the nature and severity of the problem, and perhaps provide some suggestions about how to deal with the problem.  Testing may also help to measure progress in dealing with the problem” (Hogan, 2007 p.12).   Educational settings are another use of major test by school psychologist or counselors and the “actual users of the test information include teachers, educational administrators, parents, and the general public, especially as represented by such officials as legislators and school boards” (Hogan, 2007 p.12).  Major test in educational settings are used to determine the level at which students are learning through achievement tests and also to measure the academic success of students in the future.  Personnel testing are another use of major test and are primarily used by businesses and the military. Major test are used in businesses as well as the military to identify and select individuals that are qualified to fill available positions and typically will include measures of “general mental ability, specific job-related skills, and personality characteristics” (Hogan, 2007 p. 13).  Major test are used when conducting research in “psychology, education, and other social/behavioral sciences” (Hogan, 2007 p. 14).  In the research process the function of the test “the operational definition of the dependent variable” as well as “describing samples” and it also “involves research on the tests themselves” (Hogan, 2007 p.14). 
Reliability and Validity
Reliability and validity are two very important aspects of psychological testing that could be misinterpreted as being one and the same; however they have completely different meanings.  Reliability represents the consistency in the measurements and the validity represents whether the test measures the purpose of the test.  The value of a test is determined by reliability and validity because when results are consistent and support a hypothesis it can help researchers draw conclusion that will allow for proper diagnosis and treatment for individuals.
Conclusion
Testing is a method that is used to gather information that will measure certain abilities in individuals such as achievements, personality, interest and attitudes and neuropsychological.    The major categories of test are conducted in different settings such as clinical, educational, personnel and research that all serve a main purpose and that is to supply information to the user that could assist in helping individuals and that is why reliability and validity is very important.  Reliability and validity shows results that are consistent and specific in relation the type of test and that is what gives users assistance in providing the necessary things needed to help individuals.




Implications for the Future

The area in which we live, work, socialize and do many other things is known as the environment and that “is a term used to encompass all living and non-living things occurring naturally on Earth” ("Environment," 2010).  Human behavior has the ability to affect the environment in either a positive or negative manner and the field of environmental psychology was developed to help individuals gain understanding the relationship between human behavior and the environment.  Environmental issues are a main concern in relation to human behavior and the environment as environmentalist seek to bring about changes to improve environmental conditions.  Environmental issues “are concerned with human actions that affect the biosphere that humans and other species inhabit” (Grant, 2011).  Pollution is an environmental problem that I observe in my local community and I plan to evaluate at least two strategies for promoting positive environmental behavior.  As a part of my evaluation I will explain how positive and negative consequences can increase pro-environmental behaviors, I will also describe at least one positive and one negative example of how technological advances have impacted the environment and I will assess the influence of environmental policies.
Environmental Issue: Pollution
Pollution is defined as “unwanted or detrimental changes in a natural system.  Usually pollution is associated with the presence of toxic chemicals in some large quantity, but pollution can also be caused by the presence of excess quantities of heat or by excessive fertilization with nutrients” (Freedman, 2011).  Pollution comes in many forms such as air, water, and noise and each one of these is a major contributor to the changes in the environment that often results in a negative effect.  Pollution has a negative impact on plants animals, air and water and can cause many health problems. In this paper the focus will be on air pollution because it has the potential to cause harm to humans as well as the environment. 
Air pollution is “the release of chemicals, particulate matter or other airborne substances into the atmosphere in large enough quantities that are harmful to humans, animals or natural ecosystems” (McCreery, 2011).  Air pollution contains chemicals that are produced naturally as well as substances that are man-made and is considered to be a very serious problem in the world.  Air pollutants are broken down into two categories, primary and secondary.  “Primary air pollutants cause pollution following their direct release into the environment from the generating source.  The substance released may already be present in some quantities, but it is considered a primary pollutant if the additional release brings the total quantity of the substance to pollution levels” (Rehkopf, L, 2011).  Examples of primary pollutants can range from volcano ashes, vehicle exhaust, “smoke, soot, dust and liquid droplets released into the air either by the burning of fuel or other industrial or agricultural processes” (Rehkopf, L, 2011).  Secondary pollutants are produced “when two or more primary pollutants react in the atmosphere and cause additional atmospheric pollution” (Rehkopf, L, 2011). Smog is an example of a secondary air pollutant that occurs when vehicle exhaust and industrial pollution mix with sunlight. Urban air quality and indoor air pollution is considered to be two of the worst air pollution problems in the world and in order to solve these problems individuals must first understand the effects therefore prompting a search for methods to solve them.
Strategies for promoting positive environmental behavior
The United States congress developed The Clean Air Act which “is a federal law that attempts to improve air quality by regulating air pollution” (Kedzior, 2011).  The Clean Air Act was first developed in 1970 and enlisted the Environmental Protection Agency to develop National Ambient Air Quality Standards (NAAQS) to provide protection to public health and welfare by regulating emissions of hazardous air pollutants.  The Clean Air Act contains six titles that refer to methods to improve air quality.  The first title focuses on six of the most common air pollutants, “sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, lead, and particulate matter” (Kedzior, 2011).  The title requires that the Environmental Protection Agency set levels of amount of exposure for each state and implement a “plan that describes measures for ensuring compliance.  Noncompliant states must implement specified control measures and are subject to possible penalties” (Kedzior, 2011).  The second title “regulates the emissions of motor vehicles, aircrafts, and other moving sources.  It also supports requirements related to the emissions of vehicle-assembly plants, adoption of low-sulfur diesel fuels , and in certain metropolitan areas, use of  reformulated gasoline and vapor recovery nozzles” (Kedzior, 2011).  Title two has encouraged automobile makers to create fuel efficient automobiles as well as automobiles that only require electricity to operate.   The third title “controls the emission of hazardous or toxic pollutants connected with serious illness, including lead, mercury, and dichlorodiphenyltrichloroethane (DDT)” (Kedzior, 2011).  Title three has led to the elimination of lead-based paint being used in homes and businesses as well as the creation of recyclable batteries that prevent from batteries being thrown in the trash.  The fourth title “provides oversight of industrial emissions related to acid deposition (acid rain).  Controls measures aim to reduce sulfur dioxide and nitrogen oxides to half of 1980 emission levels” (Kedzior, 2011).  The fifth title “introduces a program for issuing and trading pollution emission permits.  The permit-trading program is run by individual states and allows for temporal and spatial distribution of pollutant emissions within and between industries” (Kedzior, 2011).  The sixth title “regulates the production and use of ozone-depleting chemical substances, such as chlorofluorocarbons”.  The sixth title requires the Environmental Protection Agency “to establish a program to gradually phase out all ozone-destroying chemicals and support, the development of ozone-friendly substitutes” (Kedzior, 2011).
The Clean Air Act is a strategy for promoting positive environmental behavior because it requires organizations to engage in using environmental friendly techniques that “have lowered the levels of six common pollutants such as particles, ozone, lead, carbon monoxide, nitrogen dioxide and sulfur dioxide, as well as many other toxic pollutants” (Clean Air Act, 2014).  Under the Clean Air Act vehicle manufactures have been required to produce environmentally friendly automobiles as well as eliminated the use of lead in gasoline.
Recycling is another strategy for promoting positive environmental behavior because “recycling is the process of taking materials that are no longer needed and turning them into new products that can be used” (Vynne, 2011).  When individuals recycle is cut downs on the amount of waste that goes into landfills and incinerators.  Recycling allows natural resources to be preserved and puts a stop to pollution by eliminating the need to use new raw materials.  Recycling has many benefits that include “reduced environmental degradation and greenhouse gas emissions, economic savings, and job creation” (Vynne, 2011). 
Recycling has been around for a very long time; however the importance of recycling has just became a growing trend as individuals have become more aware of how it affects the environment.  Many schools have begun to encourage their students to recycle by teaching them how recycling helps the environment and how not recycling can damage the environment.  When learned at an early age children can develop a high level of consciousness that would result in them being pro-environment.  Businesses along with schools have also implemented policies to encourage their workers to be pro-environment by being responsible for recycling products.
Recycling promotes positive environmental behavior because it decreases the environmental problems that are caused by landfills.  Recycling teaches individuals how to dispose of their unwanted items in a safe manner aside from just putting everything in the trash which would ultimately end up in a landfill and possibly produce methane because of the rotting of organic matter that could lead to the production of toxic fumes. 
How Positive and Negative Consequences can increase pro-environmental behavior
Positive reinforcement “refers to the addition of a stimulus following a behavior that produces an increase in the future likelihood of that behavior or similar behaviors in similar settings” (Fitzgerald, 2005).  Recycling is a pro-environmental behavior that results in positive consequences because individuals that recycle also save money because items that are recycled cost less money.  Negative reinforcement “also always produces an increase in the probability of a response, but does so by removing, or subtracting, a stimulus that is aversive following a behavior” (Fitzgerald, 2005). Individuals that do not adhere to the rules and regulations on recycling are subject to fines and penalties, which is a negative consequence that can increase pro-environmental behavior.
Examples of how technological advances have impacted the environment
Technological convergence is the process in which technologies that currently exist come together to produce new technology.  The convergence history in cars is a classic example of how technological advances have impacted the environment in a positive and negative manner.  “The first technology convergence in cars was the steam power, and the second was electrical power, later, technology convergence came about for the gas powered car, which is still being used today” ("Technological convergence throughout the eras," 2009).   The technological advance of cars has had a negative impact on the environment because the exhaust that was produced by cars caused pollution to the environment.  However the technological advances of cars also has a positive impact on the environment because through technology and Environmental Protection Agency regulations automobile makers are inclined to produce more environmental friendly cars that require less gasoline because they are designed to be fuel efficient.
Influence of Environmental Policies
Environmental policies are defined as “ a government’s chosen course of action of plan to address issues such as pollution, wildlife protection, land use, energy production and use, waste generation, and waste disposal” (McCue, Wolf,  & Muhr, 2003).  Environmental polices influence human behavior because it requires individuals to be more conscious of their behavior in relation to the environment.  Environmental polices set rules and regulations that individuals are required to follow to demonstrate pro-environmental behaviors.  The Environmental Protection Agency works to develop guidelines that individuals are required to follow to eliminate pollution and other things that negatively affect the environment.
Conclusion
Pollution is an environmental issue that I have observed in my community as well as surrounding areas.  Air pollution not only causes environmental issues it also creates health problems for individuals that are exposed to airborne pollutants for an extended period of time.  Recycling in conjunction with the Clean Air Act are strategies that promote positive environmental behavior because they require individuals to engage in methods that are environmental friendly and if individuals do not follow the rules and regulations they are subject to penalties and fines from the United States Government.  The technological advances of cars has had positive and negative impacts on the environment because while the exhaust from gasoline has a negative impact on the environment, car manufacturers are diligently working to develop cars that are fuel efficient and produce less exhaust in the air therefore cutting back on the airborne pollutants that come for vehicle emissions.


How human behavior can negatively and positively affect the environment.

Environmental psychology seeks to explore how human behavior affects the environment negatively and positively.  This paper will explore how human behavior affects the environment by explaining how environmental cues shape behavior and also evaluating how behavior can be modified to support sustainability and how this can limit a negative impact on the environment.  I will also discuss how social norms influence behaviors and beliefs about the environment and I will identify at least two possible solutions that could successfully change behavior and habits in order to lessen negative environmental impact.
Environmental Cues
Cues are defined as “elements in the environment that convey important information or trigger an affective reaction” (Steg, 2013 p.120).  Cues are a very important aspect in how the environment influences behavior because they prompt individuals to do something in relation to the environment that they are exposed to rather than something they are told to do.  A classic example of an environmental cue that has influence on human behavior is litter. Litter is the result of individuals disposing of their trash improperly in an unacceptable location such as on the ground in public. “Littering is influenced by environmental cues” (Cronin & Brandolph, 2008) and can affect the environment negatively or positively depending on the current state of the environment.  For example, in many urban areas there are certain locations where trash is piled up and individuals that frequent those areas may tend to add to the trash by dumping their own and that is human behavior negatively affecting the environment.  The presence of trash and graffiti can be seen as the norm in many areas because the individuals living in that area have become so accustomed to seeing the trash pile up and graffiti that they have no idea of how it is affecting the environment and that is why they do not make any effort in trying to clean it up.  The act of littering can affect human behavior in a positive manner in some instances when individuals are exposed to neighborhoods “that are cleaned up and people know that’s not a place to litter” (Cronin & Brandolph, 2008).  Individuals that take pride in the community that they live in will be more than likely prone to cleaning up litter no matter where they are which can send positive messages to others encouraging them to participate in cleaning up the environment.
Modifying Behavior to Support Sustainability
According the Environmental Protection Agency “sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment” (Environmental Protection Agency, 2014).  Sustainability establishes and  supports “the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations” (Environmental Protection Agency, 2014).  Normal human behavior that has been learned can be modified to support sustainability through operant conditioning which is “the modification of behavior through the management of the consequences” (Behavior modification, 2009). Behavior modification through operant conditioning can limit a negative impact on the environment because “behavior is strengthened when it is followed by a reward and weakened when followed by something aversive” (Behavior modification, 2009).  Littering is a serious offense and if caught by law enforcement you could face fines and possible imprisonment.  When the laws are enforced human behavior is modified because individuals seek to avoid punishment.  Other behaviors that have been learned can be modified to support sustainability such as doing certain things to conserve energy like turning off lights when no one is occupying the space as well as unplugging appliances that are not being used.  Conserving energy benefits the environment as well as the individual because the cost of energy usage will decrease.
Social Norms Influence on Behavior and Beliefs
Social norm can be defined as “an informal rule regarding social behavior” ("Social norm," 2009). Social norms vary between cultures and have changed with the times whereas a certain behavior that was once accepted may not be accepted now for various reasons.  Cigarette smoking is an example of a social norm that was accepted for years, however in recent times research has been conducted to uncover the many health problems that have been linked to cigarette smoking.  Uncovering the health risk of smoking cigarettes have prompted campaigns to encourage individuals to quit as well as smoking has been banned in many public places such as restaurants and bars.  Social norms influence human behavior and beliefs about the environment because they encourage conformity to what is considered normal in relation to the environment.  Social norms in relation to the environment exist when individuals “obey the norm voluntarily if their individual goals are in line with the normatively required behavior, or they might be forced to obey the norm because their individual goals differ from the normatively required behavior, in which case the enforcement of the norm presupposes the norm violations are punished” (Fehr & Fischbacher, 2004).  Recycling is an example of a social norm that has influenced human behaviors and beliefs in a positive manner about the environment because recycling is a pro-environmental behavior and when performed it encourages individuals to be more proactive in taking care of the environment. 



Solutions That Could Successfully Change Behavior and Habits  
Recycling is an example of a social norm that influence behavior and beliefs about the environment in a positive manner as well as I believe that it is a solution that could successfully change behavior and habits in order to lessen negative environmental impact.  Recycling “is an activity that aims to transform used consumer products and packaging into new products rather than disposing them of in landfills or by other means” (Sheley, 2011).   When individuals recycle the community and environment benefit because recycling “reduces the amount of waste sent to landfills and incinerators; conserve natural resources such as timber, water, and minerals, prevent pollution by reducing the need to collect new raw materials; saves energy; reduces greenhouse gas emissions that contribute to global climate change; helps sustain the environment for future generations; and helps create new well-paying jobs in the recycling and manufacturing industries in the United States” (United States Environmental Protection Agency, 2014).
Another possible solution that could successfully change behavior and habits in order to lessen negative environmental impact is the going green initiative.  Recycling is a part of the going green movement; however it has its separate entity.  The going green movement “refers to the process of selling products and/or services based on their environmental benefits” (Bhatt & Sharma, 2012).  The products that are developed in the going green movement are designed to be environmentally friendly, which means that their characteristics must be “originally grown, recyclable, reusable and biodegradable, made from natural ingredients, contain recycled contents, non-toxic chemical, contents under approved chemical, do not harm or pollute the environment, will not be tested on animals, and have eco-friendly packaging” (Bhatt & Sharma, 2012).

Conclusion
Human behavior can affect the environment in a negative or positive manner.  Environmental cues shape behavior in relation to what is considered the norm in any given situation.  Operant conditioning is a method of behavior modification that can be used to support sustainability because it reinforces rewards and consequences for certain behaviors.  Social norms influence behaviors and beliefs about the environment because people are more than likely to conform to the norm in their environment so if pro-environment actions are being practiced people who copy those same behaviors.  Recycling and going green are two possible solutions that could successfully change behavior and habits in order to lessen negative environmental impact because they encourage reusing products that would otherwise just take up space in landfills and the use of environmental friendly products that are designed to eliminate hazards.  Both recycling and going green initiative can modify behavior through social marketing, which is a guaranteed method of promoting these solutions.


The Effects of Population Density and Noise

Population density and noise can have an effect on an individual’s mental, physical and social well-being.  The field of environmental psychology seeks to analyze the effects that population density and noise have on individuals as well as many other environmental issues and concerns.  In this paper I will provide an analyst on the effects of population density and noise by addressing the concepts of territoriality, privacy, and personal space.  I will examine how the concepts of territoriality, privacy, and personal space have become more increasingly important as population become denser as well as clarify the effect of nature has on individuals living in urban environments.  As a part of my analyst I will also describe the concept of noise and examine the effect that it has on individuals and I will examine at least two strategies that can be used to reduce noise in the workplace or in the living environment. 
The Effects of Population Density and Noise
Population density is defined as “an arithmetic average expressing the number of people, animals, or plants per unity of area for a given spatial unit” (Millward, 2010).  Population density is measured by counting how people are present in a given space and dividing that number by the size of the area that is being occupied.   Population density is an important factor for humans because of the “impact it has on the way people live and interact and on the efficiency and environmental impact on their settlements” (Millward, 2010). When population density begin to increase in an area it is more than likely that the noise level will also increase as well as the privacy and personal space of an individual may be compromised.  In order to completely understand the effects of population density on an individual one must first examine the concepts of noise, privacy, territoriality, and personal space as it relates to population. 

Noise
An environmental stressor that many people encounter regularly is noise.  Noise is considered to be a form of communication, however it is defined as “unwanted sound that is typically measured as sound intensity by decibels” (Steg, 2013 p. 34).  When examining the effects of noise on individuals it is very important to first understand that “noise had the ability to change or distort the meaning of a message that is being communicated in human and electronic communication” ("Noise," 2009).  If someone is trying to convey a message to someone else yelling in a high pitch voice over loud noises in the background it may impossible for the individual to effectively communicate that message to the individual because of the noise which can be very stressful especially if the information is very important.  Noise can affect an individual’s ability to concentrate and I believe that is why teachers always require silence in the classroom while they are giving a lesson because noise can distract the students from learning.
Strategies to Reduce Noise
Noise occurs often in different types of environmental settings, such as where an individual resides or work.  After a long day of work it could be very stressful to come home to place that is very noisy and there a several steps that can be taken to help reduce the noise but first it would be beneficial to identify the source.  If it found that your neighbors are contributing the excessive noise, it may help to “make them aware of how their activities are affecting others” ("How to reduce unwanted noise," 2006).  Discuss way to decrease unpleasant noise, “such as laying down carpets, moving stereo equipment away from shared walls and agreeing on reasonable hours for noisy activities” ("How to reduce unwanted noise," 2006).  These methods are good for residential settings such as apartment complexes where residents live in very close proximity. 
The Occupational Safety and Health Administration, known as OSHA states that “engineering controls are the preferred method of reducing noise levels in the workplace” (Hunt, 2014). The use of engineering controls as a method to reduce noise in the workplace would require organizations to modify equipment.  The modification of equipment “for reducing noise produced include using sound absorption techniques, such as muffling equipment or devices to absorb vibrations” (Hunt, 2014).  An administrative control is another method that is considered to be “very effective in reducing excessive noise levels in the workplace” (Hunt, 2014).  Administrative controls can vary from room treatments “such as placing carpets and other noise barriers between the worker and the equipment can help to effectively reduce noise levels” (Hunt, 2014).  Another administrative control could be just as simple as moving equipment that produces excessive noise to another area of the workplace that employees do not frequently occupy.  Business owners should also consider replacing older noisy equipment with newer models that are more efficient and make less noise.
Understanding Territoriality, Privacy, and Personal Space
Recently we were bombarded with snow and ice storms creating chaos on the roads and I noticed on several occasions while driving through the neighborhood that many people who shoveled out parking spaces put lawn chairs, trash cans or cones in the parking spot when they moved their car although that is completely illegal here in the city many residents still saved their parking spaces which could considered to be territoriality.  Territoriality is defined as “a pattern of attitudes and behavior held by a person or group that is based on perceived, attempted, or actual control of a physical space, object, or idea which may involve habitual occupation, defense, personalization, and marking the territory” (Gifford, 2007).  Inclement weather created anxiety and stress prompting residents to save parking spaces as a way of “marking their territory” and if someone else were to attempt to occupy that parking space conflict was definitely going to escalate. 
Unlike Territoriality where an individual marks a space as their territory, personal space “is the emotionally tinged zone around the human body that people feel is their space” (Sommer, 2009).  Personal space is measured by the parameters surrounding a person that an individual considers their comfort zone.   Personal space differs from territoriality when speaking in terms of population because territoriality could be the simple act of someone saving a chair with their jacket when they go use the restroom and personal space would be the area surrounding that individual and close someone could be before they feel uncomfortable.  When population density increase it is more than likely that individual personal space will be compromised. 
Defining privacy is complex; however it can be described as “freedom from authorized intrusion” (Privacy, 2014).  Some examples of an individual’s privacy being violated are someone going through your desk drawer at work without your knowledge.  Another privacy violation that happens very often is someone entering the restroom without knocking on the door, as this is something that happens at home as well as the workplace. When an individual’s privacy is violated it may also include their personal space sometimes, like when someone barges into the restroom already occupied.   
Nature effect on individuals living in an urban environment
An urban environment can be described as an area that has a higher population density than the surrounding areas, such as cities and towns.  Urban areas are sometimes face paced and are made up of lots of buildings and have a minimal nature effect.  Due to the development of urban and metropolitan areas population density increases as well as noise which has a major impact on individuals.  The nature effect can have a positive impact on individuals in urban environments that are exposed to dense population that include overcrowding and invasion of personal space and privacy.  Green space is the term used for the nature effect in urban environments and is mostly made up of trees and grass.  Grass is considered to be one of the most resilient plants on earth because “it helps prevent soil erosion, supplies the softest play space, and cools the ambient temperature around the perfect place for picnics or star gazing” ("The Scotts company: sustainable benefits of green spaces," 2012). The presence of green space in an urban environment has a strong psychological effect on the human population because being exposed to the nature effect can help alleviate the feeling of being mentally exhausted and provide a feeling of relaxation and restoration.  The effects of nature can also “encourage social interaction and de-stressing through exercise and conversation” (Perry, 2010).
In conclusion, the impact of the increase of population density and noise is a contributing factor to individuals becoming territoriality due to a decrease in privacy and invasion in personal space.  Noise is considered to be an unwanted sound that interferes with what individuals can measure as normal sound and communication.  Aside from discussing with your neighbors ways to decrease noise in your living environment there are engineering and administrative controls that can help in the workplace.  Territoriality is when an individual marks a space to prevent others from occupying that space; on the other hand personal space is the parameter that an individual mentally sets as their comfort zone in relation to other human beings. Privacy is the guidelines set by individuals expressing their right to be left alone.  When population density increases, territoriality, personal space and privacy become compromised and that is why the nature effect is much needed because the increase in population density contributes to crowding that is a major cause to many psychological problems that individuals face.  The effects of nature can provide a calm to individuals feeling overwhelmed from the increase in population density.

Environmental Risk Perception

A combination of things that make up our surroundings, conditions, or influences is known as environment. The environment is considered to be “our life support system because it includes everything that we rely on during our lifetime such as air, water, metals, soil, rock, and other living organisms” (Sustainable environment, 2014).   Environment consists of ecological, social and cultural influences that have the ability to shape an individual’s life.  The condition of our environment is dependent upon human behavior and it is very important to understand “that we have the opportunity to either nurture or mistreat it” (Sustainable environment, 2014).  In this essay I have chosen to select pollution as an environmental risk that I would like to examine different perceptions of the level of risk. 
A common understanding of risk “refers to a situation, event, or activity which may lead to uncertain adverse outcomes affecting something that human value” (Steg, 2013 p. 16).  Environmental risk is more complex than just risk in general because they are “characterized by high complexity and uncertainty, entailing intricate casual relationships and multiple consequences” (Steg, 2013 p. 16).   Environmental risk often occurs “from the aggregated behaviors of many individual rather than a single activity (Steg, 2013 p.16)” and that is why I decided to examine the environmental risk factors of pollution.
Pollution is defined “as unwanted or detrimental changes in a natural system.  Usually pollution is associated with the presence of toxic chemicals in some large quantity, but pollution can also be caused by the presence of excess quantities of heat or by excessive fertilization with nutrients” (Freedman, 2011).  Pollution can occur in several ways such as noise, air or water and is mainly the result of human behavior.  The two articles that I examined focused on air pollution and how it contributes to health related problems.
Air pollution is used to describe the “broad range of contaminants in the atmosphere that can occur from natural causes or from human activities” (Brimblecombe, 2011).  Many air pollutants have been discovered “as gas particles and on a restricted scale they can be trapped inside buildings as indoor air pollutants” (Brimblecombe, 2011).  When discussing environmental risk factors on a scale of importance I believe that air pollution should be at the top of that list because air is something at all humans have to consume on a daily basis in order to survive and if the air is bad is can be the cause many health related problems. 
The first article I examined was about air pollution and health.  This article discussed how “exposure to pollutants such as airborne particulate matter and ozone has been associated with increases in mortality and hospital admissions doe to respiratory and cardiovascular disease” (Brunekreef & Holgate, 2002).  This article viewed the effects of air pollution based on short-term studies in which the differences between individuals that were terminally ill and otherwise healthy were compared to determine if being exposed to air pollutants caused serious health problems.  The study that was conducted was trying to gain “knowledge on which pollution components are responsible for any health effects observed in epidemiological studies of obvious importance” (Brunekreef & Holgate, 2002). 
The next article I examined focused on air pollution and epigenetics.  This article discussed how “air pollution is a global problem with far-reaching environmental impacts” (Syed, Hew, Kohli, Knowlton, & Nadeau, 2013).  The authors of this article are trying to explain to readers how being exposed to air pollution is connected to several health problems as well the importance of “understanding the impact of ambient air  pollution is complicated given the diversity of both pollutants involved as well as the complexity of associated diseases” (Syed, Hew, Kohli, Knowlton,  & Nadeau, 2013).  This article gave an outline on the serious health problems that can occur as a result of ambient air pollution and made suggestions on involving “epigenetic modifications, including DNA methylation, histone acetylation, and microRNAs” (Syed, Hew, Kohli, Knowlton,  & Nadeau, 2013).
Risk perception is defined as “people’s subjective judgment about the risk associated with some activity, event, or technology” (Steg, 2013 p. 24).   In the first article I examined on air pollution and health the risk perception was focused more on “sources of ozone, particulate matter, and nitrogen dioxide” (Brunekreef & Holgate, 2002).  The author basically discussed how the effects of the ozone contributed to air pollution and how they perceived those effects to contribute to health related problems in humans.  In the next article I examined on air pollution and epigenetics the risk perception was focused on air pollutants such as the ozone, particulate matter, diesel exhaust particles and cigarette smoke and the relationship between  “ambient air pollution and the incidence of respiratory diseases” (Syed, Hew, Kohli, Knowlton,  & Nadeau, 2013).  The article air pollution and epigenetics risk perception was higher than air pollution and health because that article took a more in depth look on the relationship between air pollution and health problems such as respiratory diseases such as bronchitis and asthma.
            Environmental stressors are situations that happen mostly by human behavior that cause pressure on individuals as well as the environment.  Both articles identify diesel exhaust as an environmental stressor because diesel exhaust gives off fumes that contribute to health problems that affect an individual’s respiratory system.  State laws have been adapted to prohibit vehicles that run on diesel fuel for idling for more than five minutes at any given time.  Prohibiting diesel vehicles from idling for more than five minutes was developed to reduce the amount of air pollution that comes from the exhaust fumes of a vehicle operated by diesel fuel. 
Diesel fuel is an environmental stressor because the fumes are strong and if an individual inhales too much it will cause them to cough and possibly choke depending on how long they have been exposed to the fumes.  I honestly agree with the regulations that were made on the idling of diesel vehicles because I drive a school bus and I have been exposed to the fumes on several occasions and they caused me to cough repeatedly and then I developed a headache.  Another risk perception that was identified but I did not discuss much was cigarette smoke.  Cigarette smoke has been identified as “one of the most widely studied environmental exposures, particularly with regard to gene-environment interactions” (Syed, Hew, Kohli, Knowlton,  & Nadeau, 2013).  Several studies have been conducted over a period of time to determine the relation between cigarette some and many diseases such as “respiratory diseases such as COPD, asthma, and lung cancer, as well as cardiovascular diseases and other cancers” (Syed, Hew, Kohli, Knowlton,  & Nadeau, 2013).  Laws have been developed prohibiting cigarette smoking in many businesses such as hospitals, restaurants and bars which I believe was a very good way to eliminate people especially children being exposed to cigarette smoke.  I believe that individuals that are exposed to cigarette smoke regularly can possibly develop chronic breathing problems because cigarette smoke is very strong and every time that I have been exposed to it I felt shortness of breath and coughed excessively.
