ABA research design
A Skinnerian variant of the experimental method consisting of exposing one subject to 3 experimental phases: (A) a baseline period, (B) introduction of reinforcers to change the frequency of specific behaviors, and (A) withdrawal of reinfocement and observation of whether the behaviors return to their earlier frequency (baseline period).

ABC assessment
In behavioral assessment, an emphasis on the identification of antecedent events and the consequences (C) of behavior, and a functional analysis of behavior involving identification of the environmental conditions that regulate specific behaviors
behavioral assessment
The emphasis in assessment on specific behaviors that are tied to defined situational characteristics (e.g., ABC approach)
behaviorism
An approach within psychology, developed by Watson, that restricts investigation to overt, observable behavior.
classical conditioning
A process, emphasized by Pavlov, in which a previously neutral stimulus becomes capable of eliciting a response because of its association with a stimulus that automatically produces the same or a similar response.

conditioned emotional reaction
Watson and Rayner's term for the development of an emotional reaction to a previously neutral stimulus as in Little Albert's fear of rats.
counterconditioning
The learning (or conditioning) of a new response that is incompatible with an existing response or stimulus.
determinism
The belief that people's behavior is caused by a lawful scientific manner; determinism opposes a belief in free will.
discrimination
In conditioning, the differential response to stimuli depending on whether they have been associated with pleasure, pain, or neutral events.
extinction
In conditioning, the progressive weakening of the association between a stimulus and a response; in classical conditioning extinction occurs because the conditioned stimulus is no longer followed by reinforcement.
fixed (schedules of reinforcement)
schedules of reinforcement in which the relation of behaviors to reinforcers remains constant.

functional analysis
In behavioral approaches, particularly Skinnerian, the identification of the environmental stimuli that control behavior.
generalization
In conditioning, the association of a response with stimuli similar to the stimulus to which the response was originally conditioned or attached.
generalized reinforcer
In Skinner's operant conditioning theory, a reinforcer that provides access to many other reinforcers (e.g. money).
maladaptive response
In the Skinnerian view of psychopathology, the learning of a response that is maladaptive or not considered acceptable by people in the environment.
operant conditioning
Skinner's term for the process through which the characteristics of a response are determined by its consequences.
operants
In Skinner's theory, behaviors that appear (are emitted) without being specifically associatated with any prior (eliciting) stimuli and are studied in relation to the reinforcing events that follow them.
punishment
An aversive stimulus that follows a response.
sample approach
Mischel's description of assessment approaches in which there is an interest in the behavior itselg and its relation to environmental conditions, in contrast to sign approaches that infer personality from test behavior.
schedule of reinforcement
In Skinner's operant conditioning theory, the rate and interval of reinforcement of responses (e.g., response ratio schedule and time intervals).
shaping
In Skinner's operant conditioning theory, the process through which organisms learn complex behavior through step-by-step processes in which behavior increasingly approximates a final, target response.
sign approach
Mischel's description of assessment approaches that infer personality from test behavior, in contrast with sample approaches to assessment.
situational specificity
The emphasis on behavior as varying according to the situation, as opposed to the emphasis by trait theorists on consistency in behavior across situations.
successive approximation
In Skinner's operant conditioning theory, the development of complex behaviors through the reinforcement of behaviors that increasingly resemble the final form of behavior to be produced.
systematic desensitization
A technique in behavior therapy in which a competing response (relaxation) is condition to stimuli that previously aroused anxiety.
target behaviors (target responses)
In behavioral assessment, the identification of specific behaviors to be observed and measured in relation to changes in environmental events.
token economy
Following Skinner's operant conditioning theory, an environment in which individuals are rewarded with tokens for desirable behavior.
variable (schedules of reinforcement)
Schedules of reinforcement in which the relation of behaviors to reinforcers changes unpredictably.
