摘要
实验材料是取样规则不同的两组(有限制组和无限制组)矩阵图形和离散度不同的两组(大离散度组和小离散度组)矩阵图形。每个图形以两种速度及在三个距离上呈现。被试者的任务是从比较图形中再认出先前呈现的那个图形。结果表明:被试者再认无限制组图形的成绩优于有限制组的成绩,小离散度组的成绩也优于大离散度组的成绩。速度因素对辨认的影响大于距离因素的影响。由取样规则所带来的关系参数和离散度这个物理的参数可用于预测图形辨认的成绩。
Four groups of matric histoform, namely, the random metric figures,the restricted motric figures, the large dispersion metric figures, the smalldispersion metric figures were used as target figures in this study. Each groupconsisted of 6 metric figures. Each figure was presented by two kinds ofexposed time (1/2 sec. 4/5 sec.) and was put on three distances (40M. 80M.120M.). The subject was required to recognize the target figure from the 6comparable figures as soon as possible. The results showed that the subject’s recognition performance of therandom figures was better than that of the restricted figures. Similarly,recognition performance of the small dispersion figures was better than thatof the large dispersion figures. The effect of exposed time on recognition wasmore pronounced. It may be argued that the relational parameter which comesfrom the sampling rule and dispersion may be used as a predictor ofperformance in some perceptual tasks.
