  • 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.
  • 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.
  • 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).
  • Post reinforcement pause
    A pause in responding that follows the delivery of reinforcement on fixed interval or fixed ratio schedules of reinforcement.

    A variation of basic intermittent schedules of reinforcement in which reinforcement is delivered for any response that differs in topography, sequence, etc., from a previously reinforced response.

    A reinforcement schedule during which only some instances of a behavior are reinforced.

    Time-filling behaviors that occur as a result of reinforcement schedules, at times when reinforcement isn’t available. These behaviors are not related to the specific reinforcement yet tend to occur in…
  • Chained and tandem schedules are both compound schedules. They require correct responding that must also occur in a specific order for reinforcement to be delivered. But that may not be as easy as it sounds. PTB co-founder Dana Meller explains. Refer to the 5th Edition Task List Section B-5 Define and provide examples of schedules of reinforcement.Dana Do's: Chained Versus Tandem Schedules Explained
    Chained and tandem schedules are both compound schedules. They require correct responding that must also occur in a specific order for reinforcement to be delivered. But that may not be as easy as it sounds.
