The frequency of occurrence of functors in obligatory contexts was studied in verbal autistic and mentally retarded children matched for nonverbal mental age, and the percentages of correct use of functors were rank-ordered. The grammatical complexity of their language was also described using a transformational grammar. The data were compared to those obtained in a normal group matched for mental age and to the data presented by Brown (1973) and deVilliers and deVilliers (1973) in younger children. The autistic subjects omitted functors frequently and independently of the grammatical complexity of their language. The rank ordering of morphemes was consistent within both the autistic and mentally retarded groups but showed no correlation between the two groups or to the rank ordering described by deVilliers and deVilliers. It is suggested that functors in autistic subjects may develop in an atypical but consistent order and that this may be due to specific semantic deficits, particularly in the areas of person and time deixis.
对语言能力与非语言心理年龄相匹配的自闭症儿童和智力发育迟缓儿童在强制性语境中功能词出现的频率进行了研究，并对功能词正确使用的百分比进行了排序。还使用转换生成语法描述了他们语言的语法复杂性。将这些数据与在心理年龄匹配的正常组中获得的数据，以及布朗（1973年）和德维利尔斯夫妇（1973年）在年幼儿童中呈现的数据进行了比较。自闭症受试者频繁省略功能词，且与他们语言的语法复杂性无关。语素的排序在自闭症组和智力发育迟缓组中都是一致的，但两组之间以及与德维利尔斯夫妇描述的排序之间均无相关性。研究表明，自闭症受试者的功能词可能以一种非典型但一致的顺序发展，这可能是由于特定的语义缺陷，尤其是在人称和时间指示方面。
