Which of the following is NOT a negative symptom of schizophrenia?

Hallucinations are symptoms that fall under the category of positive symptoms in schizophrenia. Positive symptoms are characterized by the presence of abnormal behaviors and experiences, such as delusions and hallucinations, which are indicative of an excess of thought processes. In contrast, negative symptoms are associated with the absence or diminishment of normal functions. These may include blunt affect, which refers to a reduced emotional expression, anhedonia, which is the inability to experience pleasure, and avolition, which involves a decrease in motivation to initiate and sustain purposeful activities. Recognizing the distinction between positive and negative symptoms is crucial in understanding schizophrenia and its treatment.
