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。 In this study, 15 deaf subjects and 15 subjects with normal hearing were selected. Under the condition that the two stimuli were presented on time, the responses of deaf individuals and normal hearing persons A comparative study on the perceptual sensitivity of human topological properties. The results show that: (1) In general, there is no significant difference between respondents’ response to topological equivalence and topological property difference, and there is no significant difference between deaf and normal hearing people on stimulus map response. (2) For deaf people, there is no significant difference between stimulus maps in response to long-term and short-term; while in normal hearing, stimulus maps are better than short-term responses to long-term responses.
