This week's psychology course was interesting because we covered information about B.F. Skinner, who had developed his own theory on positive reinforcement. Positive reinforcement takes place when a behavior is followed by a situation that increases the probability of that particular behavior occurring in the future (Engler, 2005). Negative reinforcement takes place when a behavior is followed by the termination of an unlikable situation increasing the probability of the behavior in similar circumstances (Engler, 2005). Punishment occurs when a behavior is followed by an unlikable situation that is intended to do away with the punished person's behavior. I think that B.F Skinner's theory is interesting because it is possible that some people's behavior are the result of different influences in their life. I also found it interesting in class that the teacher found similarities among different students who had influences of punishment and positive reinforcement in their childhood background. I also think that the theory of behaviorism can be the key to understanding the influences of many psychological conditions that people have in life.
