本研究运用三项测试,考查了学龄弱智儿童语言发展状况。结果表明,弱智儿童语言发展过程和规律与正常儿童相似,并没有脱离正常儿童语言发展的一般模式,但他们语言发展速度极其缓慢,即使匹配了智龄,也远不如正常儿童,而且弱智儿童在语言运用上有其特点,与正常儿童有“质”的差异。 This study uses three tests to examine the language development of mentally retarded children. The results showed that the process and laws of mentally retarded children’s language development were similar to those of normal children and did not depart from the general pattern of normal children’s language development. However, their language development rate was extremely slow. Even if they matched their intellectual age, they were far less than those of normal children and mentally handicapped children Language has its own characteristics, and normal children have “qualitative” differences.
