聋人与听力正常人拓扑性质差异知觉敏感性的比较实验研究

本研究选取15名聋人与15名听力正常人被试,在两种刺激图对呈现时间条件下,通过考察其对拓扑性质等价和拓扑性质差异图对的反应,对聋人与听力正常人拓扑性质差异的知觉敏感性进行比较研究。研究结果表明:(1)总体上,被试对拓扑性质等价和拓扑性质差异图对的反应不存在显著差异,聋人与听力正常人对刺激图对的反应不存在显著差异。(2)对聋人来说,刺激图对长时间和短时间呈现的反应不存在显著差异;而对听力正常人来说,刺激图对长时间呈现的反应则优于短时间呈现。

A Comparative Experimental Study on Sensitivity of Perception of Topological Difference in the Deaf and Normal-hearing People

Using 15 deaf people and 15 normal-hearing people as subjects,and two different types of presentation duration,we study subjects' reaction to figures with topological difference and non-topological difference.We then compare the hearing-impaired and normal-hearing subjects in terms of their perception sensitivity to typological differences.The results show that:(1) In general,there is no significant difference between the perception judgment of topological difference figures and non-topological difference figures.There is no significant difference between the deaf and normal-hearing people in response to the figures.(2) For the hearing-impaired,there is no significant difference regarding the perception judgment of figures presented in long and short duration.However,normal-hearing subjects do better in the perception judgment of figures presented in long duration than in short duration.
