Definitions:

Discriminative Stimulus

A stimulus in the presence of which a particular response will be reinforced, indicating the appropriate context for that behavior.

Rewarding Stimuli

Stimuli that increase the likelihood of a repeat of the behavior that they follow due to their positive effects.

Self-Monitoring

A phase of self-management and an intervention technique. Self-monitoring involves the process of operationally defining a target behavior and having students observe and record its occurrence or absence while engaging in some activity or task.

Contingent Reinforcer

A reinforcement given only after a specific behavior is exhibited, thereby increasing the likelihood of that behavior occurring again.
