本研究采用因素分析的方法研究聋人和听力正常人在快速和慢速两种呈现条件下对复杂视觉图形信号的认知绩效。结果表明 :( 1 )组别变量对视认知绩效的影响比较显著 ,聋人组的反应正确率较高而平均反应时却较长 ;( 2 )呈现速度变量对视认知绩效的影响十分显著 ,慢速呈现条件下的反应时较短 ;( 3 )正确反应时比错误反应时短。 In this study, we used factor analysis to study the cognitive performance of complex visual pattern signals in deaf and normal hearing persons under both fast and slow rendering conditions. The results showed that: (1) The effect of group variables on cognitive performance was significant, while the deaf group’s response rate was higher and average response time was longer; (2) The effect of presenting speed variable on visual recognition performance was very high Remarkably, the response time under slow rendering conditions is shorter; (3) The correct response is shorter than the error response.
