选取12名聋人被试与16名听力正常人被试,采用“不同拓扑等价性条件下目标刺激检测任务”的实验范式,对聋人与听力正常人的拓扑性质知觉进行了比较研究。结果表明:(1)在对拓扑等价任务和拓扑不等价任务的反应速度上,听力正常人存在显著差异,表现为对拓扑不等价任务的反应速度快于拓扑等价任务;聋人不存在显著差异。(2)在对拓扑等价任务和拓扑不等价任务的反应准确性上,聋人和听力正常人均不存在显著差异。(3)聋人和听力正常人对拓扑等价任务和拓扑不等价任务的反应速度均不存在显著差异。(4)聋人和听力正常人在对拓扑等价任务的反应准确性上不存在显著差异,而在对拓扑不等价任务的反应准确性上存在显著差异,表现为听力正常人的反应准确性高于聋人。
Twelve deaf subjects and 16 subjects with normal hearing were selected to study the topological properties of deaf and normal hearing subjects by using the experimental paradigm of “target stimuli detection task under different topological equivalence conditions”. The results show that: (1) There is a significant difference in the response rate of topological equivalence tasks and topological inequality tasks, which is manifested in that the responses to topological inequality tasks are faster than topological equivalence tasks; There are no significant differences. (2) There is no significant difference between deaf and normal hearing persons in the accuracy of response to topological equivalence tasks and topological inequality tasks. (3) There is no significant difference in response speed between deaf and normal hearing persons for topological equivalence tasks and topological inequality tasks. (4) There is no significant difference in the accuracy of response to the topological equivalence task between the deaf and the normal hearing people, but there is a significant difference in the accuracy of the response to the topological inequality task, which is manifested as the accurate response of normal hearing people Sex is higher than deaf people.
