Definitions:

Operant Conditioning

A method of learning that occurs through rewards and punishments for behavior, aiming to influence the occurrence of behavior through these consequences.

Higher-order Conditioning

A form of learning in which a stimulus is paired with a previously conditioned stimulus, leading to a new learned response without directly being paired with the unconditioned stimulus.

Negative Reinforcement

A technique used to increase desired behaviors by removing an unpleasant stimulus when the desired behavior is performed.

Positive Reinforcement

A behavior modification technique that involves rewarding a desired behavior, thereby increasing the likelihood that the behavior will be repeated.
