Definitions:

Primary Reinforcer

A stimulus that satisfies basic survival needs and is inherently rewarding, such as food, water, or shelter, which does not require learning to be effective.

Secondary Reinforcer

A conditioned reinforcer that gains its reinforcing power through its association with a primary reinforcer; examples include money, grades, or tokens.

Variable Interval

A schedule of reinforcement where a response is rewarded after an unpredictable amount of time has passed, making it a powerful tool in the study of operant conditioning.

Schedules of Reinforcement

Schedules of Reinforcement are the rules that determine how and when a behavior is reinforced in operant conditioning, critical in shaping and maintaining behaviors.
