Which symptom involves derailment, tangentiality, or incoherent speech?

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

Answer: (A)

Disorganized thinking (speech) is seen when a person’s thoughts are not logically connected, leading to derailment, tangentiality, or incoherence. Derailment is a loosening of associations where ideas jump from one topic to unrelated ones. Tangentiality means the speaker answers a question with responses that wander off topic and never return to the point. Incoherence, or illogical speech, makes the spoken language hard to follow or understand. Together, these features reflect a disruption in thought formation and organization rather than what a person is perceiving or how they move. Hallucinations are sensory experiences without external stimuli (for example, hearing voices). Negativism involves resistance or opposition to instructions. Grossly disorganized or abnormal motor behavior (catatonia) refers to unusual movements or posture and behavior, not thought form.
