对2岁和3岁的自闭症谱系障碍儿童(n=10)和21个月大的典型儿童(n=13)进行了两种语言习得过程(先理解后产生语序，名词偏向)的研究。跨情态优先观察被用来评估对主语-动词-宾语语序的理解以及将新词映射到宾语而不是动作的倾向。还收集了自发的语音样本。结果显示，两组受试者在生产前对语序都有显著的理解能力。此外，两组儿童都一直表现出名词偏向。先于产生的理解和名词偏向似乎是语言习得的强大过程，在典型的语言障碍人群和语言障碍人群中都能观察到。
Two language acquisition processes (comprehension preceding production of word order, the noun bias) were examined in 2- and 3-year-old children (n=10) with autistic spectrum disorder and in typically developing 21-month-olds (n=13). Intermodal preferential looking was used to assess comprehension of subject-verb-object word order and the tendency to map novel words onto objects rather than actions. Spontaneous speech samples were also collected. Results demonstrated significant comprehension of word order in both groups well before production. Moreover, children in both groups consistently showed the noun bias. Comprehension preceding production and the noun bias appear to be robust processes of language acquisition, observable in both typical and language-impaired populations.
