18. Negative symptoms of schizophrenia include which of the following?

Answer: A

Explanation:

Flattened emotional responses are a negative symptom of schizophrenia.

Negative symptoms of schizophrenia include flattened emotional responses, which refer to a diminished display of emotions or affect in interpersonal situations.

A) Flattened emotional responses

This option is correct as flattened emotional responses represent a key negative symptom of schizophrenia. Individuals may show a reduced ability to express emotions, leading to a lack of facial expressions, voice modulation, and gestures, which can significantly impact their social interactions.

B) Disorganized behaviors

Disorganized behaviors are not classified as negative symptoms but rather fall under the category of positive symptoms. These behaviors may include erratic actions or an inability to organize thoughts and actions effectively, indicating a disruption in cognitive processes rather than a lack of emotional expression.

C) Disorganized speech patterns

Similar to disorganized behaviors, disorganized speech patterns are considered positive symptoms of schizophrenia. They reflect a thought disorder that affects the individual's ability to communicate coherently rather than a decrease in emotional expression.

D) Delusions

Delusions are also categorized as positive symptoms. They involve strongly held false beliefs that are resistant to reason or contrary evidence, which contrasts with the concept of negative symptoms that focus on the absence or reduction of normal emotional functions.

Conclusion

Flattened emotional responses are definitively a negative symptom of schizophrenia, highlighting the diminished emotional expression characteristic of the disorder. In contrast, the other options—disorganized behaviors, speech patterns, and delusions—do not pertain to negative symptoms, as they indicate the presence of abnormal thoughts or actions rather than an absence of emotional responsiveness.
