BACB ABA Principles and Concepts 2

Question 1

Which schedule of reinforcement delivers reinforcement after a fixed number of responses?

Accepted Answer

Fixed ratio

Answer

A fixed ratio (FR) schedule delivers reinforcement after a set, unchanging number of responses, producing high and steady rates of responding.

Question 2

What is the term for the decrease in responding that occurs during the interval following reinforcement on a fixed interval schedule?

Accepted Answer

Post-reinforcement pause

Answer

The post-reinforcement pause is the period of little or no responding that occurs immediately after reinforcement delivery on fixed interval and fixed ratio schedules.

Question 3

Which concept best describes responding maintained by a history of reinforcement continuing briefly into extinction before stopping?

Accepted Answer

Resistance to extinction

Answer

Resistance to extinction refers to how long or how much behavior continues after reinforcement is discontinued, often greater after variable than fixed schedules.

Question 4

Stimulus control is said to be present when a behavior occurs more frequently in the presence of a specific stimulus than in its absence. What is that stimulus called?

Accepted Answer

Discriminative stimulus (SD)

Answer

A discriminative stimulus (SD) is a stimulus in the presence of which a particular behavior has been reinforced and therefore occurs at a higher rate.

Question 5

Which process involves the gradual increase in response requirements or decrease in reinforcement frequency to maintain behavior?

Accepted Answer

Schedule thinning

Answer

Schedule thinning is the gradual reduction in the frequency of reinforcement or increase in response requirements to maintain behavior under leaner schedules.
