<正> 問題 在重性精神病的研究工作中,利用患者对不同刺激反应特点来探討疾病的病理机制,是頗为多見的。19世紀奥伯斯蒂納(Obersteiner,1879)和拉文-路易(Raven-Leuie,1892)在对重性精神病患者视刺激的簡单反应时間研究中,已发現患者的簡单反应时間較健康人为长。近几年来,本統(A. L. Benton,1959)除了对患者的簡单反应进行研究外,还利用不同视刺激来探討精神分裂症患者辨别反应的特点。維納勃斯(P. H. Venables,1956,1958)及肯英(H. E. King,1962)等人又研究了患者对不同強度的視、听刺激的反

1. Simple reactions of schizophrenics of paranoid type with different clinical pictures, to sound stimuli of two intensities were slower than that of normal persons. Among these patients, those with active symptoms made the slowest reaction, the unstable ones came next, and the reaction time of the remissive patients was the shortest.2. Schizophrenics of the paranoid type showed 3 kinds of characteristics in simple reaction: (1) Short reaction time with obvious regularity in accordance with intensity of the stimulus. This might be the indication that the general disturbance of cerebral function was not severe. These were mostly patients in remission; (2) Short reaction time with no obvious regularity in accordance with intensity of the stimulus. This was evidently an indication of cerebral functional disturbance in an equalization phase and a paradoxical phase; (3) Long reaction time. This indicated serious functional disturbance of the narcotic phase. Patients with active and unstable symptoms belonged to this group.3. After talking about matters related to paranoid delusions, or after performing a complex discrimination reaction test, the cerebral functional disturbance in most of the patients became more severe in various extents.
