Reinforcers

Stimuli, events, or conditions that increase the likelihood of a behavior being repeated.

Reinforcement

In operant conditioning, any event that strengthens the behavior it follows.

Successive Approximations

A method of shaping behavior by rewarding actions that are progressively closer to the desired behavior.
