Definitions:

Positive Reinforcement

A technique used in behavior modification that involves rewarding a desired behavior in order to increase the likelihood of its recurrence.

Negative Reinforcement

A behavioral principle where the removal of an unfavorable event or outcome after the display of a behavior increases the likelihood of that behavior being repeated in the future.

Latent Learning

Learning that occurs without any obvious reinforcement or immediate demonstration of the learned behavior.

Obvious Reinforcement

Refers to a reinforcement that is clearly and directly related to a specific behavior, making the consequences of the behavior apparent.
