Negative Reinforcer

An aversive stimulus whose removal following a behavior increases the likelihood that the behavior will occur again in the future.

Positive Reinforcer

A prompt that, once introduced post-behavior, amplifies the chances of the behavior recurring.

Primary Reinforcer

A stimulus that satisfies a basic physiological need and is inherently rewarding without the need for learning.

Conditioned Reinforcer

A previously neutral stimulus that, after becoming associated with an unconditioned stimulus, acquires the ability to produce a learned response.
