| Term | Definition |
|---|---|
| Behavior | Measurable actions or physical functions including both saying and doing |
| Rate | Count per unit of time |
| Count | Number of times a behavior occurs |
| Duration | Total extent of time a behavior occurs |
| Latency | Time between onset of a stimulus and initiation of a response |
| Positive Reinforcement | When a behavior is followed immediately by the presentation of a stimulus, resulting in an increase in the future frequency of the behavior |
| Negative Reinforcement | When a behavior is followed immediately by the reduction or removal of an aversive stimulus, resulting in an increase in the future frequency of the behavior |
| Positive Punishment | When a behavior is followed immediately by the presentation of an aversive stimulus, resulting in a decrease in the future frequency of the behavior |
| Negative Punishment | When a behavior is followed immediately by the reduction or removal of a stimulus, resulting in a decrease in the future frequency of the behavior |
| Stimulus Class | Group of stimuli that all evoke the same response |
| Response Class | Group of responses that all produce the same effect on the environment |
| Verbal Behavior | Behavior reinforced through social mediation of others |
| Echoic | A verbal operant involving a vocal response evoked by a vocal stimulus that has point-to-point correspondence |
| Mand | A verbal operant evoked by an MO and followed by specific reinforcement |
| Tact | A verbal operant evoked by a nonverbal stimulus and followed by generalized conditioned reinforcement |
| Intraverbal | A verbal operant evoked by a verbal stimulus and that does not have point-to-point correspondence with that verbal stimulus |
| Contingency | Specified dependency between a behavior and its antecedents and consequences |
| Intermittent Reinforcement | Schedule of reinforcement in which only some occurrences of a behavior are reinforced |
| Rule-Governed Behavior | Behavior controlled by a verbally described contingency |
| Contingency-Shaped Behavior | Behavior learned and controlled through direct contact with consequences |
| Extinction | Withholding reinforcement for a previously reinforced behavior to reduce its occurrence |
| Shaping | Differentially reinforcing successive approximations to a terminal behavior |
| Premack Principle | Any high-probability activity may serve as a reinforcer for any low-probability activity |
| Automatic Reinforcement | Reinforcement occurring independent of the social mediation of others |
| Stimulus Control | An individual responds one way in the presence of a given stimulus and another way in its absence |
| Prompt | Additional stimuli that increases the probability that the Sd will trigger a specific response |
| Discriminative Stimulus | Stimulus in the presence of which a particular response will be reinforced |
| Behavioral Momentum | Responding to a series of high probability behaviors increases the likelihood of responding to a low probability behavior |
| Stimulus Generalization | When a response conditioned to one stimulus is evoked by novel stimuli not used during conditioning |
| Response Generalization | When an individual emits untrained responses that are functionally equivalent to the trained response |
