Rapid acquisition of linguistic categories or constructions is sometimes regarded as evidence of innate knowledge. In this paper, we examine Polish children's early understanding of an idiosyncratic, language-specific construction involving the instrumental case--which could not be due to innate knowledge. Thirty Polish-speaking children aged 2; 6…

Focuses on the effects of contextual demands on French-speaking children's spontaneous production of cleft sentences. The study shows that French children frequently produce cleft formulations when they contrast their own belief or knowledge with that of their addressee and when the matter of the disagreement concerns the agent of the action.

A longitudinal study examined two-year-olds' acquisition of the English auxiliary system after a six-week exposure to additional auxiliary input in varying sentence contexts. Results indicated that subjects did not significantly differ from a baseline group that did not receive additional input. (Author/CB)

Reports a study of two- and three-year-olds' acquisition of complex sentences with perception and epistemic verbs that took a second verb in their complements. Complement types, complementizer connectives, and the discourse contexts in which complementation occurred were specific to individual matrix verbs. (Author/CB)

We hypothesize that the conceptual relation between a verb and its direct object can make a sentence easier ("the cat is eating some food") or harder ("the cat is eating a sock") to parse and understand. If children's limited performance systems contribute to the ungrammatical brevity of their speech, they should perform better on sentences that…

A study investigated the effect of adult correction of grammatical errors during the language learning process. Four girls and four boys, ages 2 and 3, were interviewed individually, tape recorded and asked to repeat an adult sentence exactly. Overt mistakes were corrected either with an overt correction with expansion or with expansion only,…

Data from a language development project at the Polytechnic of Wales were used to compare the speech and writing of 48 monolingual English-speaking children. The 48 children came from three groups, aged 8, 10, and 12. For the collection of spoken data, the children, divided into groups of three, were tape recorded while they made a construction…

A discussion of young children's production of English utterances with missing constituents focuses on the omission of subjects. The theory that young children have different grammars from those of adults is disputed, and it is suggested that, instead, subjects are omitted due to performance factors. Processing limitations in child language are…

The acquisition of the copula and auxiliary "be" forms of "am,""is," and "are" was studied with 16 children. Spontaneous social speech samples were obtained from each child. One child's speech was sampled for approximately one hour per week from age 2;5 through 4;0, and for one-half hour per week from age 4;1 to 5;0. A second child's speech was…

Child acquisition of Mandarin was studied with four middle class families from Taipei, Taiwan. The 2-year-olds were taped at home playing with their families. Two of the children were taped for short periods (7 hours and 9 hours), while the other two children were studied biweekly for 14 months, which resulted in 71 hours of transcribed child…

A study investigated how Samoan adults use genitive constructions in comparison with use by four young children. Results suggest that while adults and children both favor a clausal strategy of highlighting the affected object in a manipulative activity scene, Samoan children have difficulty exploiting the grammar of genitive noun phrases to encode…

A cross-linguistic comparison of syntax acquisition patterns examined preferential subject omission in the naturally-occurring speech of three Japanese toddlers from the Tokyo area and compared the findings to data on English acquisition. Results indicate that acquisition patterns of Japanese do not mirror those of English with regard to this…
