摘要: 本研究尝试用新近发展出的一种称为多级估量的方法测量了视错觉。测量结果和经典的心理物理法(调整法)的测量结果明显相关。对一般的完形所作的比较判断,两种方法测得的数据,均随机分布在0的上下。 此种多级估量法,揭示了错觉是个模糊现象。在获得的数据基础上,作者给出了一种定义错觉强度的公式: 这里,A_0=∑μ_0(x_(?)),x_(?)=错觉强度的类别代表量(+2,+1,0,-1,-2),x_0=完形中比较线段和标准线段的比值。 此外,本研究还揭示了经典的垂直-水平错觉的一个新事实:错觉强度随着比较线段与标准线段比值的改变而发生变化。并且,每一个不同比值的完形,都引出了一个错觉的可能性分布。

Abstract: A multistage evaluation method was used to measure visual illusion.It is evident that there is,on the one hand,a good correlation betweenthe multistage evaluation method and classical psychophysical one forthe measurement of vertical-horizontal illusion and on the other handthose data obtained by both methods were randomly distributed on the line ofzero up and down for comparing the length of both horizontal lines exposed. Strength of illusion was defined as follows: x_i=cetagories(-2,-1,0,+1,+2) x_0=ratio of comparative line in length to standardized one in aConfiguration The investigation of the vertical-horizonral illusion discovered that thestrength of illusion varies with change in the ratio of comparative lines inlength to the Standardized one in the configuration.The illusion is strongestwhen the ratio is 0.8. Furthermore,the results obtained also showed that each configuration inquestion had a distribution of possibility in strength of illusion.Whereby it issuitable to describe such distribution in fuzzy sets.
