以前的工作基于家庭录像带的观察表明，可以检测到自闭症谱系障碍的婴儿和1岁时具有典型发育的婴儿之间的差异，本研究解决了自闭症是否可以在1岁时与精神发育迟滞区分开的问题。来自20名后来被诊断为自闭症谱系障碍的婴儿，14名后来被诊断为精神发育迟滞（无自闭症）的婴儿和20名发育正常的婴儿的一岁生日聚会的家庭录像带由盲评者根据特定的社交和交流行为以及重复运动动作的频率进行编码。结果表明，1岁自闭症谱系障碍儿童可以与1岁典型发育儿童和智力低下儿童区分开来。患有自闭症谱系障碍的婴儿看别人和他们的名字的频率低于智力迟钝的婴儿。自闭症谱系障碍和智力低下的婴儿比正常发育的婴儿更少使用手势和注视他人持有的物体，并且更频繁地进行重复性运动动作。这些结果表明，自闭症可以在1岁时与智力低下和正常发育区分开来。
Previous work based on observations of home videotapes indicates that differences can be detected between infants with autism spectrum disorder and infants with typical development at I year of age, The present study addresses the question of whether autism can be distinguished from mental retardation by I year of age. Home videotapes of first birthday parties from 20 infants later diagnosed with autism spectrum disorder, 14 infants later diagnosed with mental retardation (without autism), and 20 typically developing infants were coded by blind raters with respect to the frequencies of specific social and communicative behaviors and repetitive motor actions. Results indicated that 1-year-olds with autism spectrum disorder can be distinguished from 1-year-olds with typical development and those with mental retardation. The infants with autism spectrum disorder looked at others and oriented to their names less frequently than infants with mental retardation. The infants with autism spectrum disorder and those with mental retardation used gestures and looked to objects held by others less frequently and engaged in repetitive motor actions more frequently than typically developing infants, These results indicate that autism can be distinguished from mental retardation and typical development by I year of age.
