The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
Learned industriousness is a behaviorally rooted theory developed by Robert Eisenberger to explain the differences in general work effort among people of equivalent ability. According to Eisenberger, individuals who are reinforced for exerting high effort on a task are also secondarily reinforced by the sensation of high effort.
Other theories may focus on additional factors such as whether the person expected a behavior to produce a given outcome, but in the behavioral theory, reinforcement is defined by an increased probability of a response. The study of reinforcement has produced an enormous body of reproducible experimental results.
Reinforcement and punishment are the core tools through which operant behavior is modified. These terms are defined by their effect on behavior. "Positive" and "negative" refer to whether a stimulus was added or removed, respectively. Similarly, "reinforcement" and "punishment" refer to the future frequency of the behavior.
Reinforcement is more likely to influence behavior if given shortly after the response is emitted. The longer people have to wait for a reward, the less effect and the less they will learn. This is the principle of delay discounting. Immediate token reinforcement can bridge later reinforcement. [7]
Behavioral momentum is a theory in quantitative analysis of behavior and is a behavioral metaphor based on physical momentum.It describes the general relation between resistance to change (persistence of behavior) and the rate of reinforcement obtained in a given situation.
Reinforcement, a key concept of behaviorism, is the primary process that shapes and controls behavior, and occurs in two ways: positive and negative. In The Behavior of Organisms (1938), Skinner defines negative reinforcement to be synonymous with punishment, i.e. the presentation of an aversive stimulus
The biopsychological theory of personality is similar to another one of Gray's theories, reinforcement sensitivity theory. The original version of Gray’s reinforcement sensitivity theory of personality was developed in 1976 and Gray revised it independently in 1982. Then in 2000 further and more thorough revisions were made alongside McNaughton.
