Variable ratio schedule (VR)
A basic schedule of intermittent reinforcement in which a variable number of correct responses must be emitted for reinforcement to be delivered.

Task List Reference: B-5
Define and provide examples of schedules of reinforcement.
Variable interval schedule (VI)
A basic schedule of intermittent reinforcement in which a variable amount of time must elapse before a single correct response produces reinforcement.

The Ultimate Reinforcement Schedules Showdown ➠ FT/VT vs. FI/VI
PTB co-founder Dana Meller delves into the differences and nuances between fixed-time (FT) and variable-time (VT) schedules, as well as fixed-interval (FI) and variable-interval (VI) schedules.
Refer to BCBA® Task List (5th ed.) Sections B-5: Define and provide examples of schedules of reinforcement; and G-14: Use reinforcement procedures to weaken behavior (e.g., DRA, FCT, DRO, DRL, NCR).

Tandem schedules of reinforcement
A compound schedule of reinforcement in which two or more un-signaled (No SD) basic schedules of reinforcement are in effect and must be met successively for the response to contact

Ratio strain
When challenging behaviors reemerge because of an abruptly thinned reinforcement schedule.
Progressive schedule of reinforcement
A variation of basic intermittent schedules of reinforcement in which the criteria for reinforcement is systematically increased, independent of the client’s behavior, until responding stops (the breaking point).

Multiple schedules of reinforcement
A compound schedule of reinforcement in which two or more basic schedules of reinforcement are in effect and alternated in a random sequence for one or more behaviors. An SD

Mixed schedules of reinforcement
A compound schedule of reinforcement in which two or more un-signaled (No SDs) basic schedules of reinforcement are in effect in an alternating, random sequence for one or more behaviors.

Matching law
A behavioral concept that maintains that behavior is produced in direct proportion to the reinforcement that is available for that behavior. Hint: We make behavior choices at every moment, and
