Reinforcing Activities

Activities or actions that increase the likelihood of a behavior being repeated by providing a positive outcome or reward.

Premack's Probability-Differential Theory

A theory that suggests more probable behaviors will reinforce less probable behaviors.

Response Deprivation Theory

A theory suggesting that behavior can serve as a reinforcement when access to the behavior is restricted and its frequency falls below a preferred level.
