Definitions:

Classical Conditioning

The process of learning that happens when an ambient stimulus is paired with a stimulus that occurs naturally, causing a learned behavior.

Operant Conditioning

A means of learning in which the magnitude of an action is shaped by reinforcements or consequences.

Delayed Reinforcement

A conditioning process where there is a time delay between the behavior and the reinforcement.

Observational Learning

Learning that occurs through observing the behavior of others and the outcomes of those behaviors.
