Definitions:

Second-order Conditioning

A form of learning where a stimulus that was previously neutral is associated with a conditioned stimulus to elicit the same conditioned response, without the original unconditioned stimulus.

Habituation

A procedure in which a life form diminishes or halts its response to a recurring stimulus as time goes by.

Sensitization

The process where repeated administration of a stimulus results in the progressive amplification of a response.

Higher-order Conditioning

A conditioning process in which a stimulus that's already associated with a reflex becomes associated with a new, neutral stimulus.
