Definitions:

Positive Reinforcement

A method of strengthening desired behavior by offering motivating incentives or rewards when the behavior is exhibited.

Extinction

A reinforcement contingency in which a behavior is followed by the absence of any consequence, thereby reducing the likelihood that the behavior will be repeated in the same or similar situations.

Negative Reinforcement

A type of conditioning where an undesirable outcome or event is removed following a behavior, increasing the likelihood of that behavior's occurrence in the future.

Social Cognitive Theory

A theoretical framework that emphasizes the importance of observational learning, social experiences, and environmental factors in the development of behaviors.
