Given two concurrently available chained schedules of reinforcement, and represent the number of responses made during alternative A and B’s initial link stimulus. t a {\displaystyle t_{a}} and t b {\displaystyle t_{b}} represent the average duration of each choice’s respective terminal link.
ABA is an applied science devoted to developing procedures which will produce observable changes in behavior. [3] [9] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, [10] but it uses principles developed by such research, in particular operant conditioning and classical conditioning.
A primary reinforcer, sometimes called an unconditioned reinforcer, is a stimulus that does not require pairing with a different stimulus in order to function as a reinforcer and most likely has obtained this function through the evolution and its role in species' survival.
An unconditioned stimulus is one that naturally and automatically triggers a certain behavioral response. A certain stimulus or environment can become a conditioned cue or a conditioned context, respectively, when paired with an unconditioned stimulus. An example of this process is a fear conditioning paradigm using a mouse. In this instance, a ...
Note that a motivating operation differs from a discriminative stimulus (Sd). A discriminative stimulus signals the availability of reinforcement, while a motivating operation changes the effectiveness of a reinforcer. [2] Nine main unconditioned (i.e. not learned) motivating operations, have been identified in humans. Deprivation of food ...
A token economy is a system of contingency management based on the systematic reinforcement of target behavior. The reinforcers are symbols or tokens that can be exchanged for other reinforcers. [1] A token economy is based on the principles of operant conditioning and behavioral economics and can be situated within applied behavior analysis ...
A patent drawing of the GED, an aversive conditioning device. Aversives may be used as punishment or negative reinforcement during applied behavior analysis.In early years, the use of aversives was represented as a less restrictive alternative to the methods used in mental institutions such as shock treatment, hydrotherapy, straitjacketing and frontal lobotomies.
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.
