Question
Difficulty: hard. Skill: analyze. Type: concept discrimination.
A student contacts two different consequences for the same response across settings, and responding shifts toward the setting with more reliable access. Across 7 sessions in service week 23, 2 observers recorded 47 minutes of observation in the elementary classroom. The BCBA's interpretation should:
AAssume the same process is operating across all settings because the topography is similar.
BChange the procedure after one session without comparing antecedents and consequences.
CName the consequence by how it sounds to staff rather than by its effect on future behavior.
DClassify the contingency by the future effect on behavior and whether a stimulus is added or removed.Correct answer

Explanation
Answer DThe decision point is: Does the answer classify the behavioral principle by function, controlling variables, and future effect? This item specifically tests Operant and respondent extinction through a applied-client-service-scenario format. The key clue is in the stem facts: A student contacts two different consequences for the same response across settings, and responding shifts toward the setting with more reliable access. Across 7 sessions in service week 23, 2 observers recorded 47 minutes of observation in the elementary classroom. The BCBA's interpretation should: Answer D is strongest because it follows this rule: Classify the contingency by the future effect on behavior and whether a stimulus is added or removed. It fits the source-backed rule without announcing that rule in the stem. The tempting mistake is to choose a shortcut before the scenario's prerequisite is satisfied. This choice weakens the data basis for the decision. A defensible answer must check whether the measurement, observation, or visual-analysis evidence supports the next step. Exam move: name the missing prerequisite first, then eliminate answers that jump to a label, a familiar procedure, a single data point, or an undocumented action.

ClueWhat the stem gives youA student contacts two different consequences for the same response across settings, and responding shifts toward the setting with more reliable access. Across 7 sessions in service week 23, 2 observers recorded 47 minutes of observation in the elementary classroom. The BCBA's interpretation should:
TrapCommon trapPositive punishment for an increasing behavior. This often shows up as negative means bad or punitive..
FixIf you missed this itemRewrite the miss as a rule: "When I see Reinforcement and punishment by behavior change, I must identify the relevant evidence before choosing the action." Then answer two related B domain questions without reading explanations first.

Why the other choices are weaker
AChoice AThis choice weakens the data basis for the decision. A defensible answer must check whether the measurement, observation, or visual-analysis evidence supports the next step.
BChoice BThis choice treats a procedure or response form as enough. The scenario still requires matching the action to function, assessment results, or the decision rule.
CChoice CThis choice is weaker because it does not resolve the key prerequisite in the scenario: a student contacts two different consequences for the same response across settings, and responding shifts toward the setting with more reliable access. Across 7 sessions in service week 23, 2 observers recorded 47 minutes of observation in the elementary classroom. The BCBA's interpretation should:
