FR Schedule

Fixed Ratio Schedule, a type of reinforcement schedule used in behavioral psychology where a response is reinforced only after a specified number of responses have occurred.

Reinforcement Given

The delivery of a stimulus following a behavior that increases the likelihood of that behavior being repeated.

Fixed Time Interval

In operant conditioning, a reinforcement schedule where a response is rewarded only after a specified amount of time has elapsed.

Variable Time Interval

A schedule in operant conditioning where reinforcement is provided after varying intervals of time.
