| Term | Definition |
|---|---|
| antecedent exercise | Antecedent exercise is a proactive intervention where a client engages in aerobic activity to reduce problem behaviors. It is implemented independently of the maladaptive behavior and is used to treat issues like SIB, aggression, and stereotypy. |
| antecedent intervention | A behavior change strategy that manipulates antecedent stimuli based on (a) motivating operations (evocative and abative effects), (b) stimulus control (differential availability of reinforcement), and (c) contingency-independent interventions |
| behavioral momentum | Describes the resistance to change in a behavior’s rate of responding following an alteration in reinforcement conditions. The momentum metaphor has also been used to describe the effects produced by the high-probability (high-p) request sequence. |
| enriched environment | An intervention that provides noncontingent access to preferred sources of reinforcement. This noncontingent access to preferred reinforcers arranges a competition between the enriched environment and the stimulation provided by the problem behavior. |
| fixed-time schedule | A schedule for the delivery of noncontingent stimuli in which a time interval remains the same from one delivery to the next. |
| functional communication training (FCT) | An antecedent intervention in which an appropriate communicative behavior is taught as a replacement behavior for problem behavior usually evoked by an establishing operation (EO); involves differential reinforcement of alternative behavior (DRA). |
| high-probability request sequence (high-p) | An antecedent intervention in which two to five easy tasks with a known history of learner compliance (the high-p requests) are presented in quick succession immediately before requesting the target task, the low-p request. |
| noncontingent reinforcement (NCR) | A procedure in which stimuli with known reinforcing properties are presented on fixed-time (FT) or variable-time (VT) schedules completely independent of behavior; often used as an antecedent intervention to reduce problem behavior. |
| restraint | 3 types of restraint are used in ABA. Personal restraint is when a therapist physically holds someone to stop a behavior. Protective equipment uses gear to prevent serious injury. Self-restraint is when a person restricts their own movements. |
| variable-time schedule | A schedule for the delivery of noncontingent stimuli in which the interval of time from one delivery to the next randomly varies around a given time. |
