What preschool children do and do not do with ungrammatical word orders

Akhtar [J. Child Lang. 26 (1999) 339.] found that when 4-year-old English-speaking children hear novel verbs in transitive utterances with ungrammatical word orders (e.g., Elmo the tree meeked), they correct them to canonical SVO order almost all of the time. However, when 3-year-olds and older 2-year-olds hear these same utterances, they waver between correcting and using the ungrammatical ordering. In the current study, we adapted this task for children at 2;4, using an intransitive construction. The major finding was that children corrected the noncanonical word order less than half as often as Akhtar's 2-year-old subjects who were approximately 4 months older. At the same time, however, children showed in several ways that they had some implicit understanding of canonical SV order; for example, they used the novel verb which they heard used in grammatical word order more often than the novel verb which they heard in ungrammatical word order, and they consistently used pronouns and the progressive –s auxiliary in appropriate ways. The current findings thus contribute to a growing body of theory and research suggesting that the ontogenetic emergence of linguistic categories and schemas is a gradual process, as is the emergence of categories in other domains of cognitive development
