We present a neural network model of learning and processing the English past tense that is based on the notion that experience-dependent cortical development is a core aspect of cognitive development. During learning the model adds and removes units and connections to develop a task-specific final architecture. The model provides an integrated…

Recent studies on the acquisition of semantics have argued that knowledge of the universal quantifier is adult-like throughout development. However, there are domains where children still exhibit non-adult-like universal quantification, and arguments for the early mastery of relevant semantic knowledge do not explain what causes such…

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…

Examines the relationship between children's attribute saliency and metaphor interpretation. Findings indicate that attribute saliency for the individual perceiving the metaphor plays a key role in the interpretation process. (Author/CB)

Relationships between "combinatorial" abilities in language, symbolic play, blockbuilding, and non-semantic action sequences were explored in a study of 30 infants between 82 and 91 weeks of age. Subjects were observed in a laboratory playroom setting for approximately 45 minutes. During this time, a number of tasks were administered…

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…

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.

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)

Discusses the audio and video-recorded longitudinal data from six infants with varying degrees of vision. The findings indicate that there are basic differences in early language, which appear to reflect differences in cognitive development. (SL)

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)

This paper represents a preliminary attempt to determine universals of grammatical development in children. On the basis of language acquisition data, a limited number of findings are presented in the form of suggested developmental universals. These universals are grouped according to the psychological variables which may determine them, in the…

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)

Investigates the extent to which a representation of relative force can account for children's understanding of epistemic modals when their logical meaning is considered. Results confirm the influence of relative force and suggest that deductive inference is an early semantic component of modal terms. (29 references) (Author/CK)
