摘　　要：本实验用IBM PC/XT计算机对30名青年人和9名中年人进行图形辨别负荷实验。结果表明:(1)同时呈现的图形数量(任务困难度)、允许辨别的时间(时间忙碌程度)和年龄都是影响被试业绩的因素。(2)在需辨别的图形数较多且有辨别速度要求的任务中,不宜选用中年人。(3)通过实验求出青年人图形辨别经验公式Y=De^(B/X),D(N)=183.1441-2.3206N+0.0249N^2,B(N)=-2.0379-0.1427N+0.0008N^2。据此公式可求出在此情境下,对一定数量的图形(N),在一定时间限定内(X)的图形正确辨别率(Y)。This experiment was done with 30 young and 9 middle age subjects on the IBN PC/XT computer. The results showed: (1) The number of fi- gures presented simultaneously, the discrimination time allowed and the age were factors which influenced the subjects'performances. (2) It is not advisable to use middle age persons in discrimination tasks which consist of many figures and which demand high speed response. (3) The experi- ential formula of figure discrimination: Y = De^(B/X); D (N) = 183.14...
