Which of the following is NOT a symptom of schizophrenia?

Enhanced motivation is not a symptom of schizophrenia. In fact, people with schizophrenia often experience a decrease in motivation, which can manifest as an avolition or lack of drive to engage in activities, fulfill responsibilities, or pursue personal goals.

In contrast, catatonic behavior refers to an abnormal motor behavior that can include agitation, immobility, or peculiar movements, and is recognized as one of the possible symptoms associated with schizophrenia. Decreased fluency can be linked to thought disorganization or poverty of speech, which is commonly observed in individuals with this disorder. Hallucinations, especially auditory ones, are considered hallmark symptoms of schizophrenia, where individuals may hear voices or perceive things that are not present.

Thus, the presence of enhanced motivation does not align with the typical symptom profile found in schizophrenia, making it the correct choice in this context.
