Definitions:

Primary Reinforcer

Variable-ratio Schedule

A reinforcement schedule where a response is rewarded after an unpredictable number of responses, commonly used in behavior analysis.

Unconditioned Stimulus

A stimulus that naturally and automatically triggers a response without any conditioning.

Immediate Reinforcer
