Negative symptoms of schizophrenia include:

  1. Hallucinations

  2. Delusions

  3. Loss of interest and lack of emotion

  4. Disorganized thinking

The correct answer is: Loss of interest and lack of emotion

Possible explanation Negative symptoms of schizophrenia refer to disruptions in normal emotions and behaviors, as opposed to positive symptoms such as hallucinations and delusions. Loss of interest and lack of emotion are examples of negative symptoms, whereas disorganized thinking is a positive symptom. Therefore, options A, B, and D are incorrect because they list positive symptoms rather than negative symptoms.
