Question

Difficulty: hard. Skill: analyze. Type: concept discrimination.

During requesting help in a early-intervention session, the trainee says "help" only when the therapist holds up a help card, but not when the card is absent. What does this pattern most directly show? The BCBA is reviewing the decision with a trainee.

A
The response has generalized across all relevant settings
B
The response is under stimulus control of the help card

Correct answer

C
The response is maintained by automatic reinforcement
D
The response is on extinction

Explanation

Answer B

Stimulus control is shown when a response occurs more often in the presence of a particular antecedent stimulus.

Why the other choices are weaker

A
Choice A

The response occurs only with one stimulus, so generalization is not shown.

C
Choice C

The scenario does not show automatic reinforcement.

D
Choice D

The scenario describes when the response occurs, not withholding reinforcement.
