聋生与听力正常学生在非对称性视觉搜索中的比较研究

为了比较聋生和听力正常学生在非对称性视觉搜索中的差异,本实验选取了20名聋生和20名听力正常学生作为被试,以中文汉字作为实验材料,采用传统的视觉搜索实验范式进行了研究。结果显示,在对中文汉字的视觉搜索中同样能够明显地发现非对称性现象;聋生和听力正常学生一样,也在视觉搜索中表现出非对称性,但随着视觉搜索任务难度的增大,聋生比听力正常学生表现出更高的搜索效率。

A Comparative Study on Visual Search Asymmetries between Deaf Students and Normal students

In order to compare the different processes of visual search asymmetries in deaf students and normal students, 20 deaf students and 20 normal students are selected to perform a visual search task using Chinese characters as the experiment materials through traditional paradigm of doing visual search experiment. The research indicates that asymmetry also exists in visual search of Chinese characters, and both of the two groups of students show asymmetrical pattern in visual search. At the same time, we find that the visual processes of the deaf are more efficient than the normal ones when the task is more difficult.
