Can music alleviate cognitive dysfunction in schizophrenia?

It has recently been reported that students performed relatively better on cognitive tasks after listening to music. Conceivably, music might reduce the level of arousal in subjects who are tense, thereby improving their performance. A test case would be schizophrenic subjects, noted for poor performance on tasks demanding attention, who have been characterized as suffering from hyperarousal, which mediates these attentional deficits. We investigated whether cognitive task performance could be facilitated by music in schizophrenics and report a beneficial effect.
