Question

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

In a home program, child's dropping to the floor when demands are presented changes after a specific antecedent and consequence arrangement. Which analysis best matches stimulus control examples? The case file includes 6 recent sessions, 1 implementer, and 1 setting.

A
Analyze the antecedent conditions and whether responding occurs across trained and untrained stimuli in relation to child's dropping to the floor when demands are presented

Correct answer

B
Continue unchanged and ignore the new contextual information
C
Add a punishment procedure before clarifying function, risk, or feasibility
D
Use the descriptive label as the explanation and treatment target

Explanation

Answer A

The clue is the combination of caregiver notes plus one direct observation, dropping to the floor when demands are presented, and the required task: Stimulus control examples. The case file includes 6 recent sessions, 1 implementer, and 1 setting. Analyze the antecedent conditions and whether responding occurs across trained and untrained stimuli in relation to child's dropping to the floor when demands are presented 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 caregiver notes plus one direct observation, dropping to the floor when demands are presented, and the required task: Stimulus control examples. The case file includes 6 recent sessions, 1 implementer, and 1 setting.

Trap
Common trap

Ignoring relevant data or context prevents a defensible behavior-analytic decision.

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

B
Choice B

Ignoring relevant data or context prevents a defensible behavior-analytic decision.

C
Choice C

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

D
Choice D

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