Question

Difficulty: medium. Skill: apply. Type: concept discrimination.

Adult client responds differently when the antecedent, consequence, or learning history changes. Which concept from stimulus discrimination examples is most relevant? The case file includes 7 recent sessions, 1 implementer, and 1 setting.

A
Add a punishment procedure before clarifying function, risk, or feasibility
B
Analyze the antecedent conditions and whether responding occurs across trained and untrained stimuli in relation to adult client's stopping work after corrective feedback

Correct answer

C
Use the descriptive label as the explanation and treatment target
D
Send the written protocol again without observing performance

Explanation

Answer B

The clue is the combination of duration data showing long pauses after feedback, stopping work after corrective feedback, and the required task: Stimulus discrimination examples. The case file includes 7 recent sessions, 1 implementer, and 1 setting. Analyze the antecedent conditions and whether responding occurs across trained and untrained stimuli in relation to adult client's stopping work after corrective feedback is best because it answers that clue through stimulus control, discrimination, and generalization instead of treating the scenario as a generic behavior problem. On exam items like this, name the decision point first, then eliminate options that rely on one report, a label, a familiar protocol, or an action that skips the relevant data check.

Why this question is hard

Clue
Key scenario clue

The clue is the combination of duration data showing long pauses after feedback, stopping work after corrective feedback, and the required task: Stimulus discrimination examples. The case file includes 7 recent sessions, 1 implementer, and 1 setting.

Trap
Common trap

A punishment-first response is weaker when less intrusive, function-based, or assessment steps have not been addressed.

Next
If you missed it, review Motivating operations versus discriminative stimuli

Then answer a few related scenarios before moving back to broad practice.

Why the other choices are weaker

A
Choice A

A punishment-first response is weaker when less intrusive, function-based, or assessment steps have not been addressed.

C
Choice C

A label is not enough; the decision should be based on observable behavior and relevant variables.

D
Choice D

Written directions alone do not verify performance or correct implementation errors.
