Definitions:

Acquisition

The process of acquiring or gaining knowledge, skills, or objects. In psychology, it often refers to the initial stages of learning.

Classical Conditioning

A conditioning technique that involves repeatedly associating two stimuli; the reaction, which at first occurs due to the second stimulus, eventually occurs due to the first stimulus independently.

Neutral Stimulus

A trigger that initially elicits no particular reaction except for capturing attention.

Unconditioned Response (UR)

An automatic, natural reaction to a stimulus that occurs without any need for prior learning or conditioning.
