摘要: 用实验方法研究规则多边图形的离散度、图形基边数、显示条件及三因素的交互作用对图形信号认知绩效的影响。实验的自变量有:(1)图形的离散度参数;(2)图形的基边数;(3)图形的显示条件。因变量是各图形信号的平均反应时。实验的刺激材料是25个不同离散度、不同基边数的规则多边图形。刺激材料的呈现与被试的反应记录都由计算机控制。结果表明:(1)离散度对图形信号认知绩效的影响十分显著,离散度适中及偏小的图形信号认知绩效较高;(2)图形基边数对认知绩效的影响十分显著,认知绩效反比于图形的基边数;(3)显示条件对认知绩效的影响不显著;(4)离散度与基边数的交互作用影响显著,离散度偏大的0.6,0.7图形与离散度偏小及适中的0.3,0.4,0.5图形的认知绩效在基边数大于8后出现明显的分离趋势。

Abstract: The experiment was conducted to investigate the interaction of regular polygon dispersion, basic side,and signals display condition. The experimental variables were: (a) 5 dispersions of polygons; (b) 5 basic sides of polygons; (c) 2 signal display conditions. The dependent variable was the average response time of each signal. The stimuli materials were 25 regular polygons with different dispersions and different basic sides. The experimental procedure was carried out on a computer, including stimuli presenting and reaction data collecting. The results showed: (a)the polygon dispersion had significant affect on signal cognitive performance (P< 0. 01 ),the polygon signals with middle(about 0. 5)or lower dispersion had higher cognitive performance; (b) the polygon basic side had significant effect on signal cognitive performance(P <0. 01), the cognitive performance was inversely related to the number of polygon sides; (c)signal display condition had no significant effect on signal cognitive performance (P> 0. 05 ); (d) the interaction of dispersion and basic side had significant effect on signal cognitive performance(P<0. 05), when the basic sides increased to the point of 8, the cognitive performance of polygons with large dispersion (0. 6, 0. 7) had a significant departure from that with smaller dispersion(0. 3, 0. 4, 0. 5).
