Question

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

In a community outing, adolescent's grabbing preferred items changes after a specific antecedent and consequence arrangement. Which analysis best matches positive and negative reinforcement contingencies? The case file includes 4 recent sessions, 1 implementer, and 3 settings.

A
Classify the consequence by whether behavior increases or decreases and whether a stimulus is added or removed in relation to adolescent's grabbing preferred items

Correct answer

B
Rely on care team's report alone and stop collecting direct evidence
C
Change the intervention immediately based on the concern alone
D
Continue unchanged and ignore the new contextual information

Explanation

Answer A

The clue is the combination of ABC data from three outings, grabbing preferred items, and the required task: Positive and negative reinforcement contingencies. The case file includes 4 recent sessions, 1 implementer, and 3 settings. Classify the consequence by whether behavior increases or decreases and whether a stimulus is added or removed in relation to adolescent's grabbing preferred items is best because it answers that clue through reinforcement and punishment by behavior change 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 ABC data from three outings, grabbing preferred items, and the required task: Positive and negative reinforcement contingencies. The case file includes 4 recent sessions, 1 implementer, and 3 settings.

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 Reinforcement and punishment by behavior change

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

Why the other choices are weaker

B
Choice B

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

C
Choice C

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.
