一些研究表明，精神分裂症患者在识别情绪面部表情方面存在困难，而其他研究表明，他们主观上报告的情绪体验与健康对照者相同。本研究的目的是探讨精神分裂症患者与对照组之间伴随情绪的生理反应是否存在差异，从而提示精神分裂症患者存在不同的基本情绪加工机制。我们向男性患者（n=26）和对照组（n=21）展示40张诱发情绪的图片，同时测量心率（HR）、呼吸频率（BR）、皮肤电导反应（SCR）和收缩压（SBP）。每个被试对每张图片的效价和唤起程度打分。采用混合效应回归模型研究主观评分与生理反应之间的关系。在两组中，BR和SCR随着觉醒等级的增加而增加，表明交感神经被激活。两组的收缩压都随着效价和唤醒等级的增加而增加。然而，尽管患者的人力资源首先随着快乐等级的降低而下降，随后随着唤醒和效价等级的提高而增加，但对照组的人力资源受到效价和唤醒等级之间复杂的相互作用的影响。因此，精神分裂症患者主观评分与SCR、BR和收缩压之间的关系与健康对照相似，但主观评分与HR之间的关系与健康对照不同。(c) 2007 Elsevier b.v.版权所有
Several studies have shown that schizophrenic patients have difficulties in their ability to recognize emotional facial expressions, whereas other research indicated that they subjectively report the same emotional experience as healthy controls. The purpose of this study was to investigate whether the physiological responses that accompany emotions differ between schizophrenic patients and controls, which would suggest a different basic emotional processing mechanism in these patients. We presented 40 emotion-eliciting pictures to male patients (n=26) and controls (n=21), while measuring heart rate (HR), breathing rate (BR), skin conductance response (SCR) and systolic blood pressure (SBP). Each subject rated each picture for its degree of valence and arousal. Mixed-effects regression models were used to investigate the relationships between the subjective ratings and the physiological responses. In both groups, BR and SCR increased with increasing arousal ratings, suggesting sympathetic activation. The SBP of both groups increased with increases in both the valence and the arousal ratings. However, whereas the patients' HR first decreased with decreasing pleasure ratings and subsequently increased with higher arousal and valence ratings, the HR in the control group was influenced by a complex interaction between valence and arousal ratings. Thus, the schizophrenic patients showed similar relationships between subjective ratings and SCR, BR, and SBP, but a different relationship between subjective ratings and HR compared with the healthy controls.
