Question
Difficulty: easy. Skill: recognize. Type: concept discrimination.
At the early intervention clinic, staff say a 5-year-old learner is "noncompliant" and ask to add a consequence. The notes only show leaving the work area after difficult demands and a break immediately afterward. Across 4 sessions in service week 1, one observer recorded 12 minutes of observation in the early intervention clinic. The most defensible response is to:
ADefine the response in observable terms and check the environmental events that reliably come before and after it.Correct answer
BAsk the team to replace data collection with a summary of the client's personality traits.
CSelect a procedure because another client with a similar label improved with it.
DTreat the caregiver's interpretation as the cause and skip direct observation.

Explanation
Answer AThe decision point is: Does the answer replace labels or internal explanations with observable behavior-environment relations? This item specifically tests Science goals: description, prediction, and control through a applied-client-service-scenario format. The key clue is in the stem facts: At the early intervention clinic, staff say a 5-year-old learner is "noncompliant" and ask to add a consequence. The notes only show leaving the work area after difficult demands and a break immediately afterward. Across 4 sessions in service week 1, one observer recorded 12 minutes of observation in the early intervention clinic. The most defensible response is to: Answer A is strongest because it follows this rule: Define the response in observable terms and check the environmental events that reliably come before and after it. 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 turns the scenario into a label instead of using observable evidence for Observable behavior and environmental explanations. It sounds efficient, but it does not answer the Science goals: description, prediction, and control decision point. 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.
