| 摘 要： | 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。

| Abstract: | The visual cognition was studied in deaf and hearing children.RT(reaction time)and the correct reactions were recorded to 24 visual complex figures in a visual-matching task.The visual complex figure was presented under different conditions,i.e.1/2sec.and 4/5sec.The results showed:1)The rate of correct reaction of the deaf group was higher while the average RT of the deaf group was longer;2)The stimuli presenting condition variable had also significant effect on signal cognitive performance,the RT of 4/5 sec.was shorter;3)The correct RT was shorter than the wrong RT. |
