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.
Initially, applied behavior analysis used punishment such as shouting and slaps to reduce unwanted behaviors. [143] Ethical opposition to such aversive practices caused them to fall out of favor and has stimulated development of less aversive methods, although such practices are still occasionally used, such as at the Judge Rotenberg Center ...
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.
negative punishment, punishment by removal, or type II punishment, a valued, appetitive stimulus is removed (as in the removal of a feeding dish). As with reinforcement, it is not usually necessary to speak of positive and negative in regard to punishment.
Discrete trial training is rooted in the hypothesis of Charles Ferster that autism was caused in part by a person's inability to react appropriately to "social reinforcers", such as praise or criticism. Lovaas's early work concentrated on showing that it was possible to strengthen autistic people's responses to these social reinforcers, but he ...
This philosophy of behavioral science assumes that behavior is a consequence of environmental histories of reinforcement (see applied behavior analysis). In his words: In his words: The position can be stated as follows: what is felt or introspectively observed is not some nonphysical world of consciousness , mind, or mental life but the ...
Punishment such as time-out and response cost are considered negative punishment, which although is still controversial, is more widely accepted than positive punishment such as overcorrection, contingent exercise, guided compliance and physical restraint. As mentioned punishment should only be used as a last resort when other methods have ...
It is intended to be used by individuals who have training in applied behavior analysis (ABA) and is primarily used by behavior analysts, speech-language pathologists, school psychologists and special educators to assess strengths and weaknesses in skills and behaviors that might impede language and social development.
