The relationship of gestural joint attention behaviors and the development of effective communication skills in autism and developmental language delay (DLD) was investigated. Autistic and DLD children matched for MA and MLU were compared on measures of gestural joint attention behavior, personal pronoun use, and spontaneous communicative behavior. DLD children responded correctly to joint attention interactions more often than autistic children, and their spontaneous gestural behavior was more communicative and developmentally advanced. Correct production of "I/you" pronouns was related to number of spontaneous initiations for autistic but not for DLD children. Measures of spontaneous joint attention behaviors were in general not related to MA, CA, or MLU for either group. DLD children's performance suggests no special impairment of joint attention skills, whereas autistic children's performance suggests a joint attention deficit in addition to a language deficit.
研究了自闭症和发育性语言迟缓（DLD）中手势共同注意行为与有效沟通技能发展之间的关系。对年龄和平均语句长度（MLU）相匹配的自闭症儿童和DLD儿童在手势共同注意行为、人称代词使用和自发交流行为方面进行了比较。DLD儿童比自闭症儿童更频繁地对共同注意互动做出正确反应，并且他们的自发手势行为更具交流性且在发育上更超前。对于自闭症儿童而非DLD儿童，“我/你”代词的正确使用与自发发起的次数有关。对于两组儿童而言，自发共同注意行为的测量结果总体上与年龄、实足年龄或MLU无关。DLD儿童的表现表明其共同注意技能没有特殊损伤，而自闭症儿童的表现表明除了语言缺陷外还存在共同注意缺陷。
