Term
|
Definition
| A metaphor to describe a rate of responding and its resistance to change following an alteration in reinforcement conditions. This metaphor has also been used to describe the effects produced by the high-p request sequence. |

|
Term
|
Definition
| A schedule for the delivery of non-contingent stimuli in which a time interval remains the same from one delivery to the next. |
|
|
Term
| functional communication training (FCT) |
|
Definition
| 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). |
|
|
Term
| high probability (high-p) request sequence |
|
Definition
| 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. |
|
|
Term
| non-contingent reinforcement (NCR) |
|
Definition
| 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 antecedent intervention to reduce problem behavior. |
|
|
Term
| variable-time schedule (VT) |
|
Definition
| A schedule for the delivery of non-contingent stimuli in which the interval of time from one delivery to the next randomly varies around a given time. |
