Explored the effect of non-signal and signal stimuli conditions upon skin conductance (SC) and finger pulse amplitude (FPA) of 8 schizophrenic patients and 6 normal controls. Both groups were assessed on a reaction time (RT) task that consisted of visual, auditory and tactile stimuli. Schizophrenics were significantly slower in the perception and reaction to visual, auditory and tactile stimuli than the normal volunteers. The autonomic reactivity of schizophrenics and normals was nonsignificant during the relaxation and non-signal stimuli conditions. However, when schizophrenics were asked to respond to signal stimuli or when an interfering stimulus was introduced, an autonomic imbalance was observed. The concept of directional fractionation provides the theoretical framework for the discussion of the autonomic results.
研究了非信号和信号刺激条件对8名精神分裂症患者及6名正常对照者皮肤电传导（SC）和手指脉搏振幅（FPA）的影响。两组均接受了一项反应时间（RT）任务评估，该任务包含视觉、听觉和触觉刺激。精神分裂症患者在对视觉、听觉和触觉刺激的感知及反应方面明显比正常志愿者更慢。在放松和非信号刺激条件下，精神分裂症患者与正常人的自主反应性无显著差异。然而，当要求精神分裂症患者对信号刺激做出反应或引入干扰刺激时，会观察到自主神经失衡。定向分离概念为自主神经结果的讨论提供了理论框架。
