Match the type of reinforcement schedule with its definition Reinforcement occurs after a set time period Reinforcement occurs after a set number of responses. reinforcement occurs after a varying time period Reinforcement occurs after a varying number of responses

A. fixed interval

B. fixed ratio

C. variable - interval

D. variable - ratio

Fixed interval: Reinforcement occurs after the set of periods. Fixed ratio: The reinforcement that occurs after a set of the numbers of the response. Variable-Interval: The reinforcement that occurs after the varying period. Variable-ratio: The reinforcement that occurs after a varying number of responses.

Thus these are the reinforcement schedule ratio.
