Which clinical findings indicate positive signs and symptoms of schizophrenia?

The correct answer is bizarre behavior, auditory hallucinations, and loose associations. These are positive symptoms of schizophrenia, reflecting a distortion or excess of normal function. Withdrawal, poverty of speech, inattentiveness, flat affect, decreased spontaneity, and asocial behavior are negative symptoms linked to schizophrenia, indicating a diminution or absence of normal function. Hypomania, labile mood swings, and episodes of euphoria are more characteristic of bipolar disorder, rather than schizophrenia.
