聋人与听力正常人拓扑性质差异知觉的比较实验研究

A Comparative Experimental Study on the Perception of Topological Difference Between Deaf and Hearing-normal People

分别选取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,本研究对聋人与听力正常人的拓扑性质差异知觉进行了比较研究。研究结果表明:(1)两种呈现时间条件下,被试对拓扑性质等价图对的反应均优于拓扑性质差异图对。(2)对于拓扑性质等价图对,被试在两种呈现时间条件下的反应不存在显著差异;而对于拓扑性质差异图对,被试则对长时间呈现的反应优于短时间呈现。(3)聋人与听力正常人在两种呈现时间条件下对两类刺激图对的反应均不存在显著差异。(4)对于聋人来说,刺激图对长时间呈现和短时间呈现的反应不存在显著差异;而对于听力正常人来说,刺激图对长时间呈现的反应则优于短时间呈现。

Using the figures of topological and non-topological difference, we selected 15 deaf people and 15 hearing-normal people, and studied their differences in the ability of perception of figures, topological difference in the situations of long-time and shot-time emerging stimulated figures. The result showed that （ 1 ） in the two situations of emerging stimulated figures, the subjects all did better in the perception judgment of non-topological difference figures than topological difference figures; （2） for the non-topological difference figures, the behaviors of subjects had no significant difference in the two situations of emerging stimulated figures; but for the Topological difference figures, the subjects did better in the situation of long-time emerging stimulated figures than in the shot-time emerging stimulated figures; （3） there was no significant difference in the perception judgment of two kinds of stimulated figures between the deaf and hearing-normal people. （4） for the deaf, there was no significant difference between the perception judgment of long-time and shot-time emerging stimulated figures; but for the hearing-normal people, the tasks of perception judgment in the situation of long-time emerging stimulated figures were better than the short-time emerging stimulated figures.
