在早期,人们普遍认为聋童获取信息的听觉渠道的损伤,会使其语言活动受到限制,造成儿童智力发展水平低下。但后来的研究发现,智力机能是独立于语言的,因此耳聋并不能直接导致智力发展的落后。一系列研究表明,聋童非言语智力测验的成绩与健听儿童大致相等,使用手语的聋童在各种视觉空间任务上显示出优于健听儿童的能力;聋童智力测验的结果和测验工具、测验实施方式有关;遗传、社会、教育等因素也对聋童的智力发展产生影响。 In the early days, it was generally accepted that impairment of the hearing-impaired children’s access to information would limit their linguistic activities and lead to low levels of mental development in children. However, later studies found that intelligence is independent of language, so deafness does not directly lead to the development of intellectual backwardness. A series of studies have shown that non-verbal intelligence tests in deaf children have roughly the same grades as hearing-good children, and deaf children who use sign language have demonstrated superior ability to listen to children in a variety of visual space tasks; results and tests of deaf children’s intelligence tests Tools, test implementation; genetic, social, educational and other factors also affect the intellectual development of deaf children.
