Definitions:

Variable-Interval Schedules

A reinforcement schedule in operant conditioning where responses are rewarded after an unpredictable amount of time has passed.

Extinction

The gradual weakening and eventual disappearance of a conditioned response when the conditioned stimulus is no longer paired with the unconditioned stimulus.

Successive Approximations

A behavior training process where closer and closer approximations to a desired behavior are reinforced until the desired behavior is achieved.

Shaping

A method of conditioning by which successive approximations towards a desired behavior are reinforced, gradually guiding the behavior closer to the target.
