Which of the following is/are positive symptom(s) of schizophrenia?

1. Flat affect
2. Heightened perception
3. Delusions

  • A.Only 1
  • B.Only 2 and 3
  • C.Only land 3
  • D.Only 1 and 2

Answer: B

Only heightened perception and delusions (2 and 3) are positive symptoms. Positive symptoms are excesses or distortions added to normal functioning, such as hallucinations, delusions, disorganised speech and heightened perception. Flat affect, a lack of emotional expression, is a negative symptom, because it is a loss of normal function, so the options including 1 are wrong.

Positive symptoms are those that are added to behaviour, whereas negative symptoms, such as flat affect, are those that take away something normal.
