Variable interval schedule: Reinforcement occurs following the first response after a variable time has elapsed from the previous reinforcement. This schedule typically yields a relatively steady rate of response that varies with the average time between reinforcements.
Variable interval: steady activity results, good resistance to extinction. Ratio schedules produce higher rates of responding than interval schedules, when the rates of reinforcement are otherwise similar. Variable schedules produce higher rates and greater resistance to extinction than most fixed schedules. This is also known as the Partial ...
The most notable schedules of reinforcement studied by Skinner were continuous, interval (fixed or variable), and ratio (fixed or variable). All are methods used in operant conditioning. Continuous reinforcement (CRF): each time a specific action is performed the subject receives a reinforcement. This method is effective when teaching a new ...
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.
The generalized matching law accounts for high proportions of the variance in most experiments on concurrent variable interval schedules in non-humans. Values of b often depend on details of the experiment set up, but values of s are consistently found to be around 0.8, whereas the value required for strict matching would be 1.0.
Herrnstein was the Edgar Pierce Professor of Psychology until his death, and previously chaired the Harvard Department of Psychology for five years. With political scientist Charles Murray, he co-wrote The Bell Curve, a controversial 1994 book on human intelligence. He was one of the founders of the Society for Quantitative Analysis of Behavior.
Reinforcement occurs when the consequence of a behavior makes it more likely for that behavior to occur in the future. Reinforcing consequences can be either positive, where something preferred is added, or negative, where something aversive is removed. [63] Reinforcement is the key element in operant conditioning and most behavior change programs.
Melioration theory accounts for many of the choices that organisms make when presented with two variable interval schedules. Melioration is a form of matching where the subject is constantly shifting its behavior from the poorer reinforcement schedule to the richer reinforcement schedule, until it is spending most of its time at the richest ...
