ABAT Core ABA Principles 3

Question 1

A discriminative stimulus (SD) signals to an organism that:

Accepted Answer

Reinforcement is available for a particular behavior

Answer

The SD is a stimulus in the presence of which a particular behavior has been reinforced in the past, making the behavior more likely to occur.

Question 2

Stimulus generalization and stimulus discrimination differ in that:

Accepted Answer

Generalization involves responding to stimuli similar to the SD; discrimination involves responding only in the presence of the SD

Answer

Generalization is responding to stimuli similar to the trained SD, whereas discrimination is confining responding specifically to the SD.

Question 3

A therapist demonstrates washing hands step-by-step and the learner then performs the same sequence. The therapist used which type of prompt?

Accepted Answer

Model prompt

Answer

A model prompt involves demonstrating the target behavior for the learner to imitate.

Question 4

In least-to-most (LTM) prompting, the practitioner:

Accepted Answer

Starts with the least intrusive prompt and increases intrusiveness only if the learner does not respond correctly

Answer

LTM prompting begins with the least supportive prompt and escalates only when necessary, allowing opportunities for independent responding.

Question 5

Shaping is defined as:

Accepted Answer

Differentially reinforcing successive approximations toward a terminal behavior

Answer

Shaping uses differential reinforcement to gradually shift responding toward a target behavior by reinforcing closer and closer approximations.
