| Term | Definition |
| Adaptation | The phrase in a behavioral program during which the student is allowed to adjust to novel stimuli in the new learning environment |
| Attenuation | The process of gradually making a schedule of reinforcement more and more intermitted |
| Auditory reinforcement | Any sound (e.g., music) for which the student will respond. |
| Aversive stimulus | A stimulus that has the effect of decreasing a behavior when it is presented as a consequence of (contingent upon) that behavior. Its is any stimulus that the individual will actively work to avoid |
| Avoidance learning | The learning that occurs when a response is made in order to avoid or escape something that is unpleasant |
| Behavior chain | A sequence of stimuli and responses that ends with a terminal reinforcer. It is also called stimulus response chain. |
| Behavior frequency | The number of times a behavior occurs during a specific period of time (see also Frequency counting) |
| Behavioral objective | A written statement that describes three things about an individuals performance of a desired behavior:
Behavior Verb, criterion, conditions |
| Behavioral physical restraint | A procedure in which the student is prevented from moving his limbs and or/body for a pre-specified period of time following the performance of misbehavior. (See also physical restraint) |
| Behavioral repertoire | The behaviors that a particular student, at a particular time is capable of performing |
| Behavioral verb | A description of the measurable behavior the student will be expected to perform. (See also |
| Bootleg reinforcement | The reinforcement that an individual receives (usually attention from peers) during a period in which no reinforcement is to be received (e.g., timeout or extinction) |
| Bridging stimulus | A stimulus used to connect the time interval between the performance of the behavior and the consequence programmed to follow that behavior |
| Conditioned aversive stimulus | A neutral stimulus that has acquired its aversive or punishing properties from being repeatedly paired with a punishing event |
