Definitions:

Stimulus Generalization

The tendency for the conditioned response to be evoked by stimuli that are similar to the stimulus that was originally associated with the response.

Response Generalization

A type of generalization that occurs when behaviors change that were not specifically targeted in the original intervention program. These behaviors are usually members of the same response class as the one targeted for intervention but have not received the intervention.

Differential Reinforcement

A technique used in behavior modification that reinforces certain behaviors while not reinforcing others, or reinforcing them differently.

Stimulus Generalization

The phenomenon where a response to a specific stimulus becomes associated with similar stimuli, leading to a similar response even in the absence of the original stimulus.
