青少年聋生的分类学联系

Deaf Adolescents' Representations of Taxonomic Relations

为了考察青少年聋生分类学联系的特点，使用不同类别的基本水平概念，完成了语义归类和错误再认2个实验，并同健听生的结果进行比较。结果表明：（1）聋生和健听生有类似的类别意识，但聋生的类别意识较健听生为弱。（2）与健听生比，呈现方式对聋生的反应影响较小。聋生的分类学概念有较强的形象化倾向。青少年聋生分类学联系的特点与他们语言能力发展迟缓、使用自然手语有关。因此，应加强聋生的规范手语教学，重视培养聋生的抽象思维能力。

Because deaf people differs from hearing people in so many ways， such as using a different language and having a relatively isolated way of living， a reasonable hypothesis is that their representation of world knowledge might have some unique characteristics compared to hearing people. In the current study we sought to investigate their representation of taxonomic categories. Our hypothesis was that deaf adolescents had stronger tendency of imagery representation of exemplars and weaker awareness of taxonomic categories than their intelligently-matched hearing counterparts.
