We compare the predictions of two different accounts of first language acquisition by investigating the relative contributions of abstract syntax and input frequency to the elicited production of main and embedded questions by 36 monolingual English-speaking toddlers aged 3;00 to 5;11. In particular, we investigate whether children's accuracy…

Six tests of the spontaneous speech of twenty-one English-speaking children (1 ; 10 to 2 ; 8; MLUs 1[middle dot]53 to 4[middle dot]38) demonstrate the presence of the syntactic category determiner from the start of combinatorial speech, supporting nativist accounts. Children use multiple determiners before a noun to the same extent as their…

Examined young children's acquisition of wh-questions. Children heard a wh-question and attempted to repeat it; a "talking bear" answered. The same format was used for two intervention sessions for children in a quasicontrol condition. Suggests very little input--if concentrated and varied and presented so the child attends to it and…

Examines speech samples from six children aged 2 years to 2 years, 5 months, with Mean Lengths of Utterance ranging from 2.93 to 4.14, were examined for evidence of six syntactic categories: determiner, adjective, noun, noun phrase, preposition, and prepositional phrase. (HOD)

Examines the spontaneous speech of Portuguese-speaking two-year olds in natural conversation with Portuguese-speaking adults. The children were separated into three groups based on Mean Length of Utterance in Words (MLUW). The children in the highest-MLUW group almost perfectly matched the adult speakers on every measure.
