The authors examined the effects of verbal and visual feedback on subjective awareness of involuntary movements in 20 chronic schizophrenic patients. At initial evaluation only 25% of the patients were fully aware of their movement disorder. Both verbal and visual feedback resulted in significant immediate enhancement of awareness. However, assessment of awareness 2 weeks later showed a return to prefeedback baseline levels. Lack of awareness of involuntary movements was associated with a lack of awareness of psychiatric disorder, and both were associated with a longer duration of illness.
作者研究了言语和视觉反馈对20名慢性精神分裂症患者不自主运动主观意识的影响。在初始评估时，只有25%的患者完全意识到自己的运动障碍。言语和视觉反馈均导致意识立即显著增强。然而，两周后的意识评估显示，意识水平又回到了反馈前的基线水平。对不自主运动缺乏意识与对精神疾病缺乏意识有关，而这两者都与病程较长有关。
