Operant Conditioning

is a learning process through which the strength of a behavior is modified by reinforcement or punishment.

Classical Conditioning

A conditioning method where two stimuli are consistently associated, leading to the response initially triggered by the second stimulus to be later triggered by the first stimulus independently.

Fixed-Interval Schedule
