The Fundamental Study of the Statistical Characteristics of Simple Reaction Time to Visual Stimulus and a Trial of Its Application to Clinical Psychiatry
視覚刺激に対する単純反応時間の統計的性質とその精神医学への応用に関する基礎的研究
About This Article
Descriptions
In the previous studies, we have been reported the difference of the statistical characteristics in simple reaction time (RT) to visual stimulus between college students and mentally deranged persons (schizophrenics). Here, to clarify the reason of the different characteristics of RT, the fundamental behavior of RT is examined. Changing the several intervals of visual stimulus, RT-test is performed on college students. The statistical parameters (average : <RT>, standard deviation : SD, and autocorrelation coefficient : R_1) of RT are investigated. It is charified that the expectation of stimulus timing has very important role in RT. The discrepancy of RT characteristics between college students and patients is also explained by the difference in the degree of expectation as a mental action.
