The MacArthur-Bates Communicative Development Inventories (CDIs) are a widely used family of parent-report instruments for easy and inexpensive data-gathering about early language acquisition. CDI data have been used to explore a variety of theoretically important topics, but, with few exceptions, researchers have had to rely on data collected in…

This research addresses the question of why some children are disposed to making a large number of pronoun case errors and others are not. The answer proposed is that when pronoun paradigm building outstrips the development of INFL, children become especially vulnerable to erring in the choice of pronominal word form, resulting in pronoun case…

There has been relatively little discussion in the field of child language acquisition about how best to sample from children's spontaneous speech, particularly with regard to quantitative issues. Here we provide quantitative information designed to help researchers make decisions about how best to sample children's speech for particular research…

Presents a quantitative study of children's noun plural overregularizations on recent comparisons of connectionist and symbolic models of language. The speech of 10 English-speaking children aged 1;3 to 5;2 were analyzed. Results pose challenges to connectionist models, but are consistent with the blocking-and-retrieval-failure model in which…

This study tests the widely cited claim that young simultaneous bilingual children reject cross-language synonyms in their earliest lexicons. First, the accuracy of the claim is examined, and then its adequacy as support for the argument that bilingual children do not have independent lexical systems in each language is considered. (JL)

Rebuts an article that claimed to overthrow the authors' 1969 findings. It is demonstrated that the original study concerned syntactic organization and that interpretation of it as bearing on comprehension is largely unjustified. Comments on their prior work in light of new developments in child language are included. (EJS)
