Operant Conditioning

A method of learning where behavior modification is achieved by either reinforcing or punishing actions.

Backward Conditioning

A learning process where a conditioned stimulus (CS) is presented after the unconditioned stimulus (US), typically resulting in weaker learning compared to forward conditioning.

Extinction

The process by which a learned behavior diminishes or disappears as a result of the repeated absence of an unconditioned stimulus or reinforcement.

Reward Centers

Brain structures that regulate the experience of pleasure and motivate individuals towards behaviors necessary for survival, such as eating and reproduction.
