Discusses the inadequacies of the linguistic development theory called cognitive determinism and suggests instead the linguistic input hypothesis. Concludes that it is not either cognitive development or linguistic input that determines linguistic growth, but an interaction between them. (RM)

This article clarifies the position taken in the Greenfield and Smith book (1976), including relation to speech act theory, and elucidates some general theoretical issues in early language development. (Author/NCR)

Suggests that Goad & Ingram's (1987) argument in favor of a cognitive model of phonological development failed to recognize the uniqueness of each individual's neural and vocal structures, ignored documented variability in the phonetic patterns of prelexical infants, and inexplicably assumed that inter-child variability implied the operation of…

Seventeen preschool children, 26 kindergarten, and 26 fourth grade childrens' knowledge structures were examined with a word association task and a match-to-sample picture task to determine whether or not children used slot-filler categories as a mediating structure between event-based and taxonomic knowledge structures as proposed by Nelson…

An experiment on children aged 2 to 7 led to a critical evaluation of Piaget's implicit contention that young children use determiners anaphorically. It is suggested that the importance of young children's processing procedures on the linguistic environment has been underestimated in Piaget's interactive epistemology. (CHK)

This study of the acquisition of kinship terms in English is a test of the hypothesis that lexical items are learned in their order of complexity and of the validity of relational analysis in predicting the order of the acquisition of kinship terms. Earlier studies of kinship terms, Piaget's in particular, are first discussed, as well as the…

Investigated the relationship between children's failures to produce unambiguous utterances and the mental effort demands in children (ages five, six, seven, and nine years), using finger-tapping and message production tasks, separately and simultaneously. Findings suggest that the relative effort requirements of communication decrease with…
