Which category covers a range of presentations from silliness to agitation affecting goal-directed behavior?

• A. Grossly Disorganized or Abnormal Motor Behavior (Catatonia)
• B. Disorganized Thinking (Speech)
• C. Negativism
• D. Hallucinations

Answer: (A)

The idea being tested is that catatonia is a broad psychomotor disturbance, and its motor manifestations can span a wide range—from playful, silly or bizarre behavior to intense agitation—both of which can interfere with goal-directed actions. This broad motor category is described as grossly disorganized or abnormal motor behavior, which covers these varied presentations and their impact on functioning. The other options focus on different symptom domains: disorganized thinking relates to speech and thought processes, negativism is a resistance or opposition to instructions, and hallucinations are false sensory experiences. None of these capture the wide spectrum of motor behavior that can disrupt goal-directed activity like catatonia can.
