Question

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

In a clinic session, learner's leaving the instructional area changes after a specific antecedent and consequence arrangement. Which analysis best matches concurrent, multiple, mixed, and chained schedules? The case file includes 4 recent sessions, 1 implementer, and 1 setting.

A
Rely on caregiver's report alone and stop collecting direct evidence
B
Change the intervention immediately based on the concern alone
C
Compare the schedule or relative reinforcement conditions before predicting persistence or allocation in relation to learner's leaving the instructional area

Correct answer

D
Continue unchanged and ignore the new contextual information

Explanation

Answer C

The clue is the combination of four sessions of stable baseline data followed by two overlapping intervention points, leaving the instructional area, and the required task: Concurrent, multiple, mixed, and chained schedules. The case file includes 4 recent sessions, 1 implementer, and 1 setting. Compare the schedule or relative reinforcement conditions before predicting persistence or allocation in relation to learner's leaving the instructional area is best because it answers that clue through schedules, persistence, and response allocation 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 four sessions of stable baseline data followed by two overlapping intervention points, leaving the instructional area, and the required task: Concurrent, multiple, mixed, and chained schedules. The case file includes 4 recent sessions, 1 implementer, and 1 setting.

Trap
Common trap

Stakeholder input matters, but direct data, context, and integrity checks are still needed for a defensible answer.

Next
If you missed it, review Schedules, persistence, and response allocation

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

Why the other choices are weaker

A
Choice A

Stakeholder input matters, but direct data, context, and integrity checks are still needed for a defensible answer.

B
Choice B

This is weaker because it skips the assessment, integrity, or decision rule needed before changing procedures.

D
Choice D

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