中文摘要：

本研究采用定义任务,探讨了弱智儿童对动物类、水果类、工具类实体名词感觉和功能语义特征的组织情况。结果发现,弱智儿童感觉特征表征贫乏,而功能特征表征相对完好。结论：弱化的感觉特征使弱智儿童在动物类和水果类的语义组织上表现出非典型性,表明这一人群更易发生生物范畴损伤,而相对完好的功能特征使弱智儿童工具类名词的语义组织与正常儿童没有差异。

英文摘要：

This study adopts defined tasks to investigate the mentally handicapped children＇s perceiving and organizing of the semantics of the substantial nouns of the categories of animals,fruits and tools.The result indicates that the mentally handicapped children are weak at the symbol of sensory characteristics but comparatively good at the symbol of functional characteristics.The conclusion is that the weakened sensory characteristics make the mentally handicapped children demonstrate untypicalness in organizing the semantics of the categories of animals and fruits,suggesting this group of people are more vulnerable in biological scope,while the comparatively good functional characteristics enable the mentally handicapped children to organize the semantics of the category of tools without difference from normal children.
