Definitions:

Learning Associations

The process by which an individual learns to link two stimuli or a behavior and its consequence, forming new knowledge.

Spontaneous Recovery

A phenomenon in which a previously extinguished response re-emerges after a period of no exposure to the conditioned stimulus.

Observational Learning

Learning that occurs through observing the behaviors of others and the outcomes of those behaviors, without direct instruction.

Associative Learning

Learning that certain events occur together. The events may be two stimuli (as in classical conditioning) or a response and its consequences (as in operant conditioning).
