Schedules of Reinforcement

Rules used to determine when reinforcement is given.

Continuous Reinforcement (CRF)

A reinforcement schedule where every response is reinforced, rapidly strengthening new behavior.

Extinction (EXT)

The process where reinforcement for a response is terminated, leading to a decrease in that behavior.

Extinction Burst

An increase in response frequency immediately following the onset of extinction.

Resurgence

The re-emergence of previously reinforced behaviors when reinforcement is not available for the target behavior.

Spontaneous Recovery

The reappearance of an extinguished behavior after a rest period.

Fixed Ratio (FR) Schedule

A reinforcement schedule that delivers reinforcement after a set number of responses.

Variable Ratio (VR) Schedule

A reinforcement schedule where reinforcement is delivered after an unpredictable number of responses.

Fixed Interval (FI) Schedule

A reinforcement schedule that delivers reinforcement after a specified time interval has elapsed.

Variable Interval (VI) Schedule

A reinforcement schedule where reinforcement is delivered after an unpredictable time interval.

Differential Reinforcement of High Rates (DRH)

Reinforcement is delivered if a minimum number of responses occurs within a specific time period.

Differential Reinforcement of Low Rates (DRL)

Reinforcement is provided if the time between responses is greater than a specified amount of time.

Differential Reinforcement of Other Behavior (DRO)

Reinforcement given for any behavior other than the unwanted behavior.

Differential Reinforcement of Incompatible Behavior (DRI)

Reinforcement provided for a behavior that is incompatible with an unwanted behavior, reducing the unwanted behavior more quickly than extinction.

Chain Schedule

A schedule that requires the completion of a sequence of behaviors in a specific order, each with its own reinforcement.

Multiple Schedule

Involves any type of specific schedule presented one after the other with different stimuli.

Mixed Schedule

Similar to a multiple schedule but with the same stimulus in every component.

Anticipatory Contrast

A phenomenon where a schedule that is more valuable leads to a higher rate of responding than a less valuable schedule.
