Definitions:

Intermittent Reinforcement

A conditioning schedule in which a reward or punishment (reinforcement) is not given every time the desired response is performed, making the response more resistant to extinction.

Continuous Reinforcement

A schedule of reinforcement in which a desirable behavior is rewarded every time it occurs, leading to rapid learning.

Extinction Contrast Effect

The increased difference in the intensity or frequency of a response observed when a previously reinforced behavior is no longer reinforced, in the presence of a contrasting condition that continues to be reinforced.

Tokens

Symbols or objects used as representations of value or exchange, often employed in token economies for behavior reinforcement.
