RBT Reinforcement Practice Questions

Both behaviors are negatively reinforced, but they differ in timing. Escape terminates an aversive stimulus that is already happening: Amir leaves while the bell is ringing, and leaving ends the noise. Avoidance prevents an aversive stimulus from occurring at all: Tessa leaves when she sees the monitor reach for the bell, so she never contacts the ringing. Swapping the two labels reverses the definitions. Calling both behaviors escape ignores that Tessa leaves before any noise starts. Calling both avoidance ignores that Amir is already exposed to the ringing when he leaves. Leaving is the same response form for both children, so the label depends on whether the aversive stimulus is present or only signaled.

A token works as a conditioned reinforcer only when it is earned through the target behavior. Keeping the container out of Felix's reach between earning opportunities prevents free access, so tokens stay contingent on completing puzzles. Letting him keep the tokens he took reinforces taking tokens and teaches that they can be obtained without work, which weakens their value. Removing every token from his board each time he takes one adds a response cost that is not in his plan and also strips tokens he legitimately earned. Switching to edible reinforcers is a plan change that requires the supervisor, and it does not fix the simple access problem the RBT created.

A newly introduced replacement behavior must be reinforced every time it occurs, so the RBT honors every break card exchange at first. Continuous reinforcement makes the card a faster, more reliable route to a break than throwing, which has a long history of reinforcement. A fixed ratio 3 schedule would ignore two out of three card exchanges, and during those unreinforced moments throwing may return as the more efficient option. A variable ratio 4 schedule is useful for maintaining a behavior after it is established, not while it is still competing. A variable interval schedule ties reinforcement to the passage of time and would leave many early card exchanges unreinforced.

Unconditioned, or primary, reinforcers are effective without any learning history because they meet biological needs: food, water, warmth, and relief from pain are the classic examples. A sip of water when thirsty and a blanket when cold provide water and warmth, so both belong on the list. Tablet time and tokens may be highly preferred, but strong preference does not make a reinforcer unconditioned; their value was learned. Praise and tokens are delivered often, yet frequency of use is irrelevant, and both are conditioned reinforcers that gained value through pairing. Listing the sip of water with tablet time and praise mixes one primary reinforcer with two conditioned ones.

Basic needs such as food, water, and restroom access are rights, not earnable privileges, so an RBT never withholds them as part of a reinforcement contingency. Giving Sam water now and continuing with his usual reinforcers protects his well-being and dignity. Requiring ten more trials for water deliberately uses deprivation to strengthen a reinforcer, which is unethical regardless of how well it works. Lowering the requirement to three trials is still withholding water, just for a shorter time. Asking his parents to approve holding water back does not make the practice acceptable, and it is not an RBT's role to propose a restrictive contingency outside the supervisor's plan.

When a conditioned reinforcer that used to work loses its value, the RBT reports the change to the supervisor, who can arrange a preference assessment, add new backup items, or adjust the plan. Sharing the observation along with the data is part of the RBT's role. Replacing the stickers with candy on the RBT's own initiative changes the reinforcement procedure without approval and may introduce an edible the family or plan does not allow. Continuing with the stickers and waiting for their value to return lets on-task behavior keep declining. Requiring twice as many stickers for each reward makes the weak reinforcer even harder to cash in and is also a plan change only the supervisor can make.

Reinforcer quality refers to how much the learner personally prefers or values a stimulus, so Oliver's favorite crackers are higher quality than pretzels he rates as just okay, and he works harder for them even in a smaller amount. Magnitude is the amount of the reinforcer, and here the pretzels are actually the larger amount, so magnitude would predict the opposite result. Immediacy is the delay between the response and the reinforcer, but both items are delivered right after each correct response. Schedule refers to how often responses are reinforced, and both items follow the same schedule. Quality is the only dimension that differs in favor of the crackers.

A backup reinforcer is the preferred item or activity a learner receives by exchanging earned conditioned reinforcers, so the five minutes of block play Wyatt gets for ten checkmarks is the backup reinforcer. The checkmarks themselves are the token reinforcers; they are delivered right after each problem and gain value because they can be exchanged. Block play is not an unconditioned reinforcer, because playing with blocks does not meet a biological need and its value was learned. A discriminative stimulus is an antecedent that signals reinforcement is available for a behavior, whereas block play arrives after the exchange as a consequence, so it cannot be functioning as a discriminative stimulus.

Preferences change from day to day and even within a session, so a brief sample of potential reinforcers right before instruction shows what Ivy wants right now and lets the RBT use that item to strengthen her motivation. Last week's ranking may no longer be accurate. Sampling is not meant to make Ivy tired of the toys; producing satiation would weaken the very reinforcers the session depends on. Sampling does not replace reinforcement during teaching trials; it informs which items the RBT delivers after correct responses. It is also not reserved for days when Ivy refuses to come to the table, because the plan calls for it before every session to keep reinforcers current.

A simple conditioned reinforcer is backed by only one reinforcer, so its value depends entirely on that item. Once Ella had eaten enough gummy bears to be satiated, the stamps that buy them lost their value too. Delivering stamps right after correct responses is good practice; immediacy strengthens a reinforcer rather than weakening it. Generalized conditioned reinforcers are backed by many different reinforcers and are more resistant to satiation, so if the stamps had become generalized, they would be expected to keep working. Edibles can back a token system perfectly well; the problem was having only one backup option, which is why supervisors often add a variety of backup reinforcers.
