FT and VT is referring to fixed time and variable time, and FI and VI is referring to fixed interval and variable interval.Answer: Although the words “time” and “interval” both refer to time-based reinforcement delivery, the distinction is which point in time that reinforcement is delivered. With fixed time and variable time schedules, we’ve got non-contingent schedules of reinforcement. That means reinforcement is contingent on the passage of time and not on behavior. Reinforcement is delivered ahead of the behavior. And again, this is the schedule for a non-contingent reinforcement procedure. The fixed interval and variable interval schedules are reinforcement schedules that are contingent on correct behavior. So, reinforcement on these schedules comes after a correct response or a correct behavior. 6th Edition TCOB.9 Identify and distinguish among simple schedules of reinforcement. G.3 Design and evaluate time-based reinforcement (e.g., fixedtime) schedules.

Learn how abrupt changes in reinforcement can lead to avoidance and aggression (ratio strain), while increased effort with no change in reinforcement can cause behavior to stop altogether (breaking point). 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.Limited hold A component that can be added to a schedule of reinforcement limiting access to reinforcement for correct responses that occur within a specific and fixed time.Lag schedule 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.Intermittent reinforcement A reinforcement schedule during which only some instances of a behavior are reinforced.Fixed ratio schedule (FR) A basic schedule of intermittent reinforcement in which a fixed number of correct responses must be emitted for reinforcement to be delivered.Fixed interval schedule (FI) A basic schedule of intermittent reinforcement in which a fixed amount of time must elapse before a single correct response produces reinforcement.Fixed interval (FI) scallop A pattern of responding specific to the fixed interval schedule of reinforcement, when the rate of responding decreases after the delivery of reinforcement, but gradually increases and speeds up at…Delays to reinforcement schedule A variation of basic intermittent schedules of reinforcement in which reinforcement for correct responding is delayed for the purpose of teaching self-control, tolerance of delayed gratification, functional communication, etc.Breaking Down a BCBA® Mock Exam Question: Response-Independent & Dependent Reinforcement Schedules in ABA Sharpen your behavior-change skills with PTB founder Dana Meller as she reviews a BCBA® mock exam question that examines an intervention aimed at reducing attention-seeking outbursts.

It sets an average amount of time between the delivery of noncontingent reinforcers.Noncontingent reinforcement (NCR) A contingency independent antecedent intervention during which reinforcers that maintain challenging behavior are delivered on a fixed or variable schedule, thereby abolishing (AO) the motivation for the client to engage…Fixed time (FT) A time-based schedule of noncontingent reinforcement delivery. It sets a fixed amount of time between the delivery of noncontingent reinforcers.Dana Do's: 1-Minute Experimental Design Test Hack (you still have to study it though) PTB co-founder Dana Meller shares a huge secret to help break down experimental design questions.
