听障生模拟量数量加工特点研究

Study on the Characteristics of Quantity Processing in Analog for the students with Hearing Impairment

文章选取32名听障初中生作为被试,通过考察面积比较任务中是否存在SNARC效应探究听障生对模拟量数量加工的特点。结果显示:(1)听障生在数字比较任务和面积比较任务中都表现出SNARC效应;(2)距离效应不仅存在于数字比较任务中也存在于面积比较任务中;(3)被试对面积比较任务的反应速度慢于数字比较任务的反应速度。这有力证实了听障生对模拟量数量加工具有空间动态性,表现出SNARC效应以及距离效应。

In order to explore the characteristics of quantity processing in analog for the students with hearing impairment, 32 heating-impaired middle school students are tested by area comparison task to investigate whether the SNARC effect exists. The results show that： （ 1 ） there is SNARC effect in both numerical comparison task and area comparison task ; （2） distance effect not only exists in the numerical comparison task but also in the area comparison task ; （3） the speed of reaction is slower in the area comparison task than in the numerical comparison task. All of the above confirms that the quantity processing in analog for students with hearing impairment shows the characteristics of spatial dynamics, SNARC effect and distance effect.
