Research is reported in which children were tested for their comprehension of four types of sentences with relative clauses. The Parallel Function Hypothesis is proposed, and implications for adult grammar are discussed. (Author/RM)

Describes an experiment where subjects were exposed to a sample of sentences from an artificial linguistic system and tested on their knowledge of the linear and hierarchical structures of the language. Suggests that learners succeed in inducing coherent grammatical systems only when input provides enough correlated cues to constituent…

Two claims about early stages of language development--that of a limitation on length of utterance and that of reduction rules which delete major constituents from simple sentences--are questioned. Supporting arguments are reviewed, and alternative explanations offered. (RM)

This study was conducted to examine the acquisition of the meaning of the temporal conjunctions "before" and "after." The initial hypothesis was that in the acquisition of a word, the child learns its semantic components one at a time. The subjects were 40 school children attending the Bing Nursery School at Stanford…

Five experiments are carried out to determine the comprehension of passives by children. Results obtained demonstrate that comprehension rests on knowledge of syntactic structure. V - NP were interpreted as verb-object. Passives lacking a preposition were interpreted as actives. Competence in passives may be at a high level before performance is…
