【Objective】 To investigate the intelligence development characteristics of children with language development delay. 【Methods】 The study population consisted of 178 children ageed 2 to 3 years with language development delay.Sign-Significant Relations (S-S method) was used for language developmental assessment,and Gesell development scale was used for developmental assessment.The statistical analysis was made on the development quotient (DQ). 【Results】 The gross motor development of the children was normal (DQ>85),the development quotient in areas of language was below normal range(DQ<76).The language development was correlative significantly with adaptive behavior development,fine motor development and personal-social behavior development (P<0.01).The incidence of lowly adaptive behavior and lowly personal-social behavior was 72.5% and 52.2%.The incidence of lowly adaptive behavior and lowly personal-social behavior was correlative significantly with language defect level (P<0.01).The incidence of lowly fine motor was 48.9%.The incidence of lowly fine motor was not correlative with language defect level (P>0.05). 【Conclusions】 The children with language development delay are often accompanied by lowly adaptive behavior,lowly fine motor and lowly personal-social behavior.Intelligence developmental assessment and comprehensive intervention are needed to children with language development delay.
