Definitions:

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.

Partial Reinforcement

A conditioning schedule in which a behavior is reinforced only some of the time, leading to a more resistant response to extinction.

Continuous Reinforcement

A method of learning where a desired behavior is reinforced each time it is displayed.
