Definitions:

Higher-Order Conditioning

A form of conditioning where a stimulus is paired with a previously conditioned stimulus, leading to a response even without the presence of the original, unconditioned stimulus.

Stimulus Substitution

A concept in conditioning where a neutral stimulus becomes associated with a meaningful stimulus and acquires the capacity to elicit a similar response.

Fixed Interval

A reinforcement schedule that rewards the first response following the passage of a specified time interval.

Variable Interval
