Psychophysiology is the science that studies the physiological measurements that are related to mental functions. In this study several physiological measurements were performed in a group of psychotic patients and their results compared with those of a normal control group. Those variables were pulse and respiratory rate, oral temperature, blood pressure and skin conductance and their spontaneous fluctuations. We observed that when direct measurements were considered, without the use of complex machinery, the psychotic patients in general, and particularly the schizophrenics had their central nervous system less stimulated than their controls. On the contrary with more complex measurements, when the EKG and skin conductance apparatus were used, the patients arousal was greater than those of their controls. The patients, in particular the schizophrenics, also did not habituate their skin conductance. Those results are considered as indicative of a decrease in the orientation reflex of those patients in comparison with their controls.
心理生理学是一门研究与心理功能相关的生理测量的科学。在本研究中，对一组精神病患者进行了多项生理测量，并将其结果与正常对照组的结果进行了比较。这些变量包括脉搏和呼吸频率、口腔温度、血压和皮肤电导率及其自发波动。我们观察到，在不使用复杂仪器进行直接测量时，一般而言，精神病患者，尤其是精神分裂症患者的中枢神经系统受到的刺激比对照组少。相反，在使用心电图和皮肤电导率仪器进行更复杂的测量时，患者的唤醒程度高于对照组。患者，尤其是精神分裂症患者，其皮肤电导率也不会产生习惯化。这些结果被认为表明这些患者与对照组相比，定向反射有所降低。
