Cognitive correlates of schizophrenia signs and symptoms: II. Emotional disturbances.
We examined the cognitive and motor correlates of emotional disturbances in 47 schizophrenia spectrum individuals. Neither affective flattening nor anhedonia was significantly associated with tasks measuring working memory or attention/concentration, or with overall performance on tasks measuring fluency or episodic memory. In contrast, as expected, emotional disturbances were associated with patterns of hemispheric lateralization. Affective flattening and anhedonia were both associated with episodic memory laterality and there were similar trends with motor laterality. Anhedonia was also associated with medication motor side effects.
