Word learning is a lifelong activity constrained by cognitive biases that people possess at particular points in development. Age of acquisition (AoA) is a psycholinguistic variable that may prove useful toward gauging the relative weighting of different phonological, semantic, and morphological factors at different phases of language acquisition…

From the field of developmental psycholinguistics and from conceptual development theory there is evidence that excessive linguistic "code-switching" in early school education may pose some hazards for the learning of young multilingual children. In this article the author addresses the issue, invoking post-Piagetian and neo-Vygotskian…

Proper Names appear at the heart of several debates in philosophy and the cognitive sciences. These include "reference", "intentionality", and the nature of "belief" as well as "language acquisition", "cognitive development", and "memory". This dissertation follows a cognitive approach to the philosophical problems posed by proper names. It puts…

In six analyses using the Child Language Data Exchange System known as CHILDES, we explored whether and how parents and their 1.5- to 5-year-old children talk about writing. Parent speech might include information about the similarity between print and speech and about the difference between writing and drawing. Parents could convey similarity…

Semantic and cognitive factors governing passive-voice comprehension were studied in kindergarten, first-, and second-grade children. (ST)

Reports on preliminary attempts to find a set of non-linguistic categories in minimally verbal infants. A methodology suitable for the presentation of semantically-defined concepts (agent and recipient) was developed. (Author/ED)

When sound takes on meaning for the first time in the life of a child, a giant and prototypic step in the development of his symbolic capacities has taken place. This step is worthy of careful scientific scrutiny. This paper seeks first to describe the steps by which the author's child discovered the existence of meaning in sound, and second, to…

A series of studies on young children's use of the terms "same" and "different" are reported. The work began from the observation that young children could respond correctly to instructions involving "same" but were often incorrect in response to "different". This finding was replicated under a variety of experimental conditions and found to be…

Children aged 3, 6, 9 and 12 years were asked to name and sort 25 different drinking vessels. Results showed three stages: (1) they ove rextend the term "cup"; (2) they focus only on certain perceptual properties; (3) they show growing awareness of functional properties and hence the vagueness of the boundary.

Since psycholinguistic research suggests that readers ascribe meaning by sampling grapho-phonemic, syntactic, and semantic text features, a study was conducted to investigate which cue strategies readers of different abilities utilized, and whether these strategies were mediated by levels of cognitive development. The subjects were 50 second grade…

A study was conducted to test an hypothesis relating semantic structures to cognitive development, specifically that the mean number of associative complexes used by a group of children will be significantly greater than the mean number of associative complexes used by a group of adolescents. The word game "Password" provided a simulation of a…

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

In this study, 50 infants (15 to 18 months of age) were shown four different film sets in an effort to determine (1) whether infants can perceive action role reversals between an actor and recipient of the action when the direction of the action is ruled out as a cue and (2) whether infants consider only animate objects to be potential…

An analysis of sentence grammar is made to show that the ability to produce coherent texts emerges slowly and late in linguistic and cognitive development. (HP)

This article discusses a study designed to determine the order of acquisition of the two expressions "in front of" and "behind," using two featureless objects. (CFM)
