Definitions:

Intermittent Reinforcement

A conditioning schedule where a behavior is reinforced only some of the time, leading to more resistant and persistent responses.

Primary Reinforcement

Secondary Reinforcement

A process in conditioning where a stimulus reinforces a behavior after it has been associated with a primary reinforcer.

Variable Ratio Schedule

A reinforcement schedule used in conditioning where a response is reinforced after an unpredictable number of responses, leading to high and steady response rates.
