Albert Bandura

According the encyclopedia of the social sciences, “Albert Bandura was born on December 4, 1925 in Mundare, a small town located in Alberta Canada” ("Albert Bandura," 2008)  .  While in high school, Bandura made a decision to take courses in psychology because is schedule left in him with spare time in which he had nothing else to do.  As a result of him taking those psychology courses he developed a genuine interest for the subject that caused him to further the study of psychology during college.  In 1952 Bandura received Bandura his PhD in 1 from the University of Iowa ("Albert Bandura," 2008).   Bandura is known to many people as the father of behavioral psychology because of his development of the social learning theory. 
Social learning theory is considered one of the most powerful theories because it incorporates ideas of conventional learning theories and the operant conditioning learning style developed by B.F. Skinner.  According to the encyclopedia of Human Relations, “social learning is a school of psychology that views personality as being shaped by the interpersonal environments in which people are raised” (Mearns, 2009).  In the beginning, social learning suggested that learning occurred mainly through impersonating the actions of others.  After more research “social learning now refers more broadly to any kind of influence our relations with others have on our behaviors, beliefs, and values” (Mearns, 2009).
While standing in line at the supermarket an individual notices that some of the people in front of them are moving to the next line so they decide to do move also, this is an example of observational learning.  Observational learning is based on an individual displaying a new behavior because they observed someone performing the same behavior.  Bandura believed that observational learning may or may not result in someone imitating a specific behavior.   A car in front of an individual that hits a pothole was used as an example, because that individual witnessed someone hitting the pothole which prompted them to swerve to avoid the pothole.  In this example the individual learned from the observation but did not imitate the behavior so Bandura concluded that what was learned was “information that was processed cognitively and acted on in a way that was advantageous” (Olson & Hergenhahn, 2013 p. 316).
Bandura demonstrated the characteristics of the learning performance during an experiment where he had children watch a film in which a model was shown hitting and kicking a large doll.  “In Bandura’s theory, a model can be anything that conveys information, such as a person, film, television program, demonstration, picture, or instructions” (Olson & Hergenhahn, 2013 p. 316).  During this experiment “one group of children saw the model reinforced for aggressiveness; a second group of children saw the model punished for aggressiveness; and for the third group the consequences of the model’s aggressiveness were neutral” (Olson & Hergenhahn, 2013 p. 316).  Soon after the children observed the film they were presented with the same doll and their level of aggressiveness towards the doll was measured.  The children who witnessed the model reinforced for aggressiveness were more aggressive; the children who witnessed the model being punished for being aggressive were not aggressive towards the doll and the children whom witnessed neutral consequences either were more aggressive or not aggressive at all.  While the children did not directly receive any type of reinforcement or punishment during this experiment, the experiment showed that the children’s behavior towards the doll changed based on the experience that was observed.
Bandura’s experiment was an important turning point in the study of behavior because the theory of behaviorism stated that an individual’s behavior was the result of rewards or punishment.  During this experiment the children did not receive any type of reward or punishment, they observed other’s interaction with the doll and then they mocked the behaviors. 
Bandura developed a modeling process to help understand that just because an individual observes a specific behavior is does not mean that they are effectively learning and also learning does not always result in a change in their behavior.  This model was developed to determine the success of social learning.  Attentional processes suggest that an individual must pay attention in order to learn.  Retentional processes suggest that in order for the information that was observed to be of any use, it must be retained.  Bandura argued that there were two retentional processes through imagination and verbally.  Once an individual is successful in paying attention and retaining the information then they will be able to demonstrate the behavior, which is known as the behavioral production process.  During the behavioral production process practice of the behavior is a very important component for improvement.  In order for an individual to repeat the behavior they have to feel motivated to do so, which is known as the motivational process.
Bandura’s social learning theory has a major effect on education because he believed that it is possible for learning to take place from experience as well as observation.  Bandura believed that if the model was a highly respectable competent individual then they would be more effective such as a teacher.  “Teachers can be highly influential models through careful planning of what is presented, they can do more than teach children routine information” (Olson & Hergenhahn, 2013 p. 337).  A teacher can demonstrate certain skills such as how to solve a problem, moral conduct and rules that a student would benefit from. 
In conclusion, Bandura’s experiments helped him to develop the social cognitive theory that put emphasis on the fact that most of the information an individual gain is a result of the contact they have with others.


Operant Conditioning

In 1937 B.F. Skinner created the term operant conditioning in perspective to the impulse of bodily processes (behavior), to distinguish his interest in behavior opposed to Ivan Pavlov theory.  Skinner defined operant behavior as “behavior controlled by its consequences” (Staddon & Cerutti, 2003).  In a more simplistic approach operant conditioning also known as instrumental conditioning is a form of learning that happens when rewards and punishments are the end result of certain behaviors.  “Through operant conditioning an association is made between a behavior and a consequence for the behavior’ (Psychology, 2013). 
B.F. Skinner’s theory of operant conditioning was established in response to Edward Thorndike’s studying learning by using animals in a puzzle box to develop his theory that is known as the “Law of Effect”.  B.F. Skinner believed that in order to understand an individual’s behavior one must first discover what created the behavior and what were the consequences.
Behavior and consequences are the highlights of operant conditioning; “with operant conditioning, the organism must respond in such a way as to produce the reinforcing stimulus” (Olson & Hergenhahn, 2013 p.75).  The main beliefs of operant conditioning relate to different situations.  In order to change an individual’s behavior, one simply has to figure out what could be used to reinforce an individual whom behavior they wish to change, wait until they display that behavior, and then use the reinforcement on the individual.  This method has to be repeated several times for an individual to understand whether or not they should be performing such behaviors.
Reinforcement is the main objective in operant conditioning because it can either increase or decrease the behavior in question.  Positive reinforcement is rewards given when an individual displays a particular behavior.  An example of a positive reinforcement is when children do well on their assignments in school and the teacher praise them with stickers on their papers and encouraging words.  This type of positive reinforcement encourages children to continue to do well on their assignments which results in them focusing more on their school work and studying.  A negative reinforcement is a punishment given when the behavior displayed is considered to be unacceptable. An example of a negative reinforcement is detention for children who did not complete their homework or classwork assignments.  Detention could be at recess or lunch time where the children would not be able to interact with their peers or it could be afterschool resulting in the caregivers having to pick them up because they miss the school bus or for kids that walk home with their friends they have to walk home by themselves getting home later than normal and missing interaction with their peers.  This negative reinforcement might encourage children to complete the necessary assignments so they do not miss out on the interaction they have with their peers. 
Positive and negative reinforcement can be equally effective depending on the individual.  There are some people who live their lives seeking approval from everyone so they are always performing behaviors that they expect to result in some type of reward.  Negative reinforcement work well during the early childhood and adolescence stages when caregivers are teaching children right from wrong.  When a child performs an unacceptable behavior they are punished and they learn not do whatever it was that resulted in them being punished.  The difference between right and wrong behaviors are established early on in life, so once adulthood is reached negative reinforcement may be the only effective reinforcement to deter individual’s from performing certain behaviors.
Operant conditioning is a method I use in my household with my children, especially with my son whom plays football.  My teenage son really enjoys football so much that he neglects his household chores as well as his schoolwork.  During the summer in order for him to participate in football he had to complete all of his household chores each day before 5:00pm or he could not attend practice.  Now that school is back in session, the coaches require him to maintain passing grades to participate.  This has been effective with him because he really enjoys football, so he makes sure that his chores are done as well as his school assignments.
In order for me to make sure that my son does what he is supposed to do for him to participate in football I posted a chore schedule on the refrigerator as well as a homework schedule.  Each day that the said task is completed he receives a star and is allowed to go to football practice and at the end of the month he receives a certain amount of allowance depending on the amount of stars he received.  This system seems to be working very well because he enjoys football and money but there are some days when he does not feel like doing anything and on those days I do not allow him to attend practice and he does not receive stars which reduces the amount of money he will receive at the end of the month.
In conclusion, the theory of operant conditioning was developed to modify an individual’s behavior through positive and negative reinforcements in their environment.  I believe that positive and negative reinforcements are equally effective during early childhood and adolescence stages because that is a critical time of learning what behaviors are right or wrong.  As an individual moves into adulthood they have already experienced those stages where they learned from right from wrong so negative reinforcements may be more effective in teaching them that certain behaviors are unacceptable.

Learning and Cognition

Many people often why an individual displays a certain type of behavior whether it be positive or negative, the question always arises is to where did they get that from.  The process is known as learning and it is something that is done every single moment consciously or unconsciously and is very important during early childhood developmental stages.  In this essay learning will be defined as well as the role behavior play in learning.  This essay will also discuss two different types of learning and the relationship between learning and cognition.
Learning is defined as “a process that results in a change in behavior, an improvement in performance, in the acquisition of knowledge, in disposition to act in particular ways” ("Learning," 2008).  Once an individual learns something a change in behavior may occur because they will have the ability to do something that they have never done prior to the learning experience.  The change in behavior can sometimes be obvious meaning that other people will notice it right away like when a child first learns to walk or it can be concealed and the individual retains the information internally without other people noticing the change.  Sometimes when an individual learns something the change in behavior might not happen right away, it may take time but it is most likely that a permanent change in behavior will take place to a certain degree once the learning experience is retained in memory and the information is rehearsed. 
There are two types of behavior, observable and unobservable.  Observable behavior is any type of behavior that can be evaluated by another person, like eating, walking and running and reading out loud.  “Examples of unobservable behaviors are thinking, imagining, learning, reading silently, and analyzing” (Harrison & Harrison, 2005).  Behavior plays an important role in learning because it is through behavior that it can be determined if and what a person has actually learned.  Behavior can also be the determining factor to whether or not a person fully understands what they learned based on their performance. 
Classical conditioning was first presented by Ivan Pavlov, where he conducted an experiment with a dog using a bell as the stimulus; he would ring the bell before giving the dog some food.  After repeatedly doing this the dog began to associate eating with the ringing of the bell (Anderman & Anderman, 2009).  Classical conditioning consists of learning a new behavior through association.  Potty training is an example of learning through classical conditioning, once the potty is presented to a young child and the caregiver brings the child to the potty soon after each meal and have them sit on the potty until they use the bathroom, the young child will soon began to develop an association between the potty and going to the bathroom and eventually start going to the potty on their own. B.F. Skinner developed the term operant conditioning through an experiment with rats and pigeons where learning something was learned as a “result of behavioral consequences” (Davis & Buskist, 2008).  When a child misbehaves and the caregiver punishes them by taking away their privileges is an example of operant conditioning, however when doing this the caregiver needs to explain to the child what they did that resulted in this punishment so it can be understood that the behavior is unacceptable.
Observational learning is when an individual’s behavior change after they have witnessed someone else doing something that may have resulted in them receiving some type of reward or consequence.  Observational learning “occurs through the cognitive processing of information displayed by models.  The information can be conveyed verbally, textually, auditorially, and through actions either by live or symbolic models such as television, movies, and the internet” (Bussey, 2002).  In order for an individual to learn from observation they have to fully understand the behavior they witnessed whether good or bad.  Observational learning is sort of like people watching and that is something that is done all the time and it is up do the individual doing the observing to decide whether or not they will mimic the behavior witnessed. Cooking is an good example of observational learning because I learned how to cook by paying close attention to my mother and grandmother while they were preparing the food and now my daughter is doing the same thing so she is learning how to cook by watching everyone.
Cognition involves the processes in the mental functions, such as the ability to see, pay attention, remember and solve problems.  Learning is the process that involves retaining information while cognition represents the necessary steps that is taken to retain that information.  You cannot have learning without cognitive abilities or vice versa.  Learning begins in early childhood developmental stages once a child experiences a number of cognitive processes and continues throughout life.  A child learning to read is an example of the relationship between learning and cognition.  Cognitive abilities such as language and memory are the processes in which a child develops the skills for reading.  Language has four levels of structure and processing and once a child has stored them in their memory it becomes a part of their learning experience.
In conclusion, learning results in a change in behavior which can be identified through performance. Classical conditioning, operant condition and observational learning are types of learning that determine the cognitive processes that support the ability to learn.  The relationship between learning and cognition is such that you cannot have learning without cognitive abilities, and cognition is a part of the learning process.
