摘要
所谓闪光融合频率,是指实验者利用仪器的调频装置。将仪器产生的闪光调节到被试分辨不出闪光,只戚觉看到的光呈一片融合的连续光时的频率,此频率卽称为闪光融合频率,又称为临界融合频率。 远在一百年前,塔尔伯特(E. B. Talbot)及伯拉图(J. Flateau)(1834年)卽研究了闪光融合频率的性质。后来一些学者不断把它用于临床医学。近年来。
Three groups of railway workers consisting of 5 key punch operators, 9 calculators and 36 dispatchers were tested on C. F. F. at different times while on duty.It is found that the fusion frequency is highest for the punch operators and calculators before work, then it decreases gradually as they proceed in their work. The fusion frequency increases slightly after each short break at two hour intervals, but never reaches the level as high as the initial values.There is no detectable change in fusion frequency for the dispatchers on day shift; but there is marked decrease after night shift. It is concluded from this study that the fusion frequency of flicker may be used to test the degree of fatigue of the central nervous system.
