Undesired Behavior

Behavior that is considered unacceptable or inappropriate by society, an individual, or a specific group.

Token-economy System

A behavioral modification technique based on systematic reinforcement, using tokens as conditional reinforcement that can be exchanged for desired rewards.

Partial Reinforcement

A conditioning schedule in which a reward is not provided every time the desired behavior is performed, leading to more resistant learned behaviors.

Extinction Procedure

A behavioral technique in which reinforcement of a previously reinforced behavior is discontinued, leading to a decrease in the frequency of the behavior.
