Intermittent Reinforcement

A conditioning schedule in which a behavior is reinforced only some of the time, leading to more resistant and lasting behavioral changes.

Continuous Reinforcement

A method of learning that involves rewarding a behavior every time it occurs, leading to faster acquisition of the behavior.
