摘要: <正> 一、問題 应某种实际需要,我們必須在閃光頻率低頻的一端选择几个适当信号,以保証人对它們的辨认达到最高准确性。国外心理学家多利用等辨量表作为选择信号的手段。所謂等辨量表,是根据人对某种刺激的辨孰程度繪制的一条曲綫,在等辨量表上纵座标的等距,代表同等程度的可辨性或混淆性。据証明,依照等辨量表上的等距所选择的信号,可以传递更多的信息。F. Attneave, W. R. Garner & H. W. Hake, E. A. Alluisi & R. C. Sidorsky等,对于不同感受系統的刺激曾进行过等辨量表的研究。J. Cohen和A. J.

Abstract: An equal discriminability scale for flash light frequencies was constructed following the procedure as outlined by W. R. Garner and H. W. Hake, with some modifications in the experimental set up. The curve plotted with the data collected showed no "end effects", and proved to be identical with the curve of successive differential limen. It was also found that, within the range of 5—182 cycle per minute, the discriminability for flash light frequencies obeys the power law.
