Definition: Positive reinforcement is a concept first described by psychologist B. F. Skinner in his theory of operant conditioning. Positive reinforcement is anything added that follows a behavior that makes it more likely that the behavior will occur again in the future. One of the easiest ways to remember this is to think of something being added to the situation. For example, imagine that your psychology professor awards you 20 extra credit points for writing a paper summarizing a PBS program you watched on animal intelligence. The bonus points are an example of positive reinforcement.
