ABA Reinforcement Schedules & Procedures 2

Question 1

A child receives a token every 5 minutes if they are on-task, regardless of how many correct responses they've made. Which schedule is in use?

Accepted Answer

Fixed interval

Answer

Fixed interval schedules deliver reinforcement after a set amount of time has elapsed since the last reinforcement, independent of response count.

Question 2

Which reinforcement schedule is most associated with a 'post-reinforcement pause' followed by a high, steady rate of responding?

Accepted Answer

Fixed ratio

Answer

Fixed ratio schedules produce a characteristic post-reinforcement pause because the organism 'knows' reinforcement just occurred and responding temporarily drops.

Question 3

In a VR-10 schedule, which of the following best describes when reinforcement is delivered?

Accepted Answer

After an average of 10 responses, unpredictably

Answer

A variable ratio 10 schedule delivers reinforcement after an average of 10 responses, but the exact number varies unpredictably around that average.

Question 4

A practitioner wants to reduce a behavior as slowly as possible during extinction by choosing the most extinction-resistant schedule. Which should they have been using?

Accepted Answer

Variable ratio

Answer

Variable ratio schedules produce the greatest resistance to extinction because the unpredictability of reinforcement maintains high, persistent responding.

Question 5

During a DRL procedure, a learner must refrain from the target behavior for at least 30 seconds before that behavior is reinforced. What does DRL stand for?

Accepted Answer

Differential reinforcement of low rates

Answer

DRL (differential reinforcement of low rates) reinforces a behavior only when it occurs at or below a specified low rate or after a minimum inter-response time.
