Definition. Functional behavior assessment (FBA) is a method developed by applied behavior analysis (ABA) to identify the variables that maintain a problem behavior. Behavior is lawful. Whether it is desirable or undesirable, behavior is controlled by environmental variables. Behavior is a function of the antecedent and consequences that make ...
t. e. Applied behavior analysis (ABA), also called behavioral engineering, [ 1 ][ 2 ] is a scientific discipline that applies the principles of learning based upon respondent and operant conditioning to change behavior of social significance. ABA is the applied form of behavior analysis; the other two are radical behaviorism (or the philosophy ...
An antecedent is a stimulus that cues an organism to perform a learned behavior. When an organism perceives an antecedent stimulus, it behaves in a way that maximizes reinforcing consequences and minimizes punishing consequences. This might be part of complex, interpersonal communication. The definition of antecedent is a preceding event or a ...
The three-term contingency (also known as the ABC contingency) is a psychological model describing operant conditioning in three terms consisting of a behavior, its consequence, and the environmental context, as applied in contingency management. The three-term contingency was first defined by B. F. Skinner in the early 1950s. [1]
The most robust form of functional assessment is functional analysis, which involves the direct manipulation, using some experimental design (e.g., a multielement design or a reversal design) of various antecedent and consequent events and measurement of their effects on the behavior of interest; [1]: 93 this is the only method of functional ...
Discrete trial training (DTT) is a technique used by practitioners of applied behavior analysis (ABA) that was developed by Ivar Lovaas at the University of California, Los Angeles (UCLA). DTT uses mass instruction and reinforcers that create clear contingencies to shape new skills. Often employed as an early intensive behavioral intervention ...
In applied behavior analysis, the Premack principle is sometimes known as "grandma's rule", which states that making the opportunity to engage in high-frequency behavior contingent upon the occurrence of low-frequency behavior will function as a reinforcer for the low-frequency behavior. [6] In other words, an individual must "first" engage in ...
Operant conditioning. Operant conditioning, also called instrumental conditioning, is a learning process where voluntary behaviors are modified by association with the addition (or removal) of reward or aversive stimuli. The frequency or duration of the behavior may increase through reinforcement or decrease through punishment or extinction.
