We present four experiments on the interpretation of pronouns and reflexives in picture noun phrases with and without possessors (e.g. "Andrew's picture of him/himself, the picture of him/himself"). The experiments (two off-line studies and two visual-world eye-tracking experiments) investigate how syntactic and semantic factors guide the…

In expressing rich, multi-dimensional thought in language, speakers are influenced by a range of factors that influence the ordering of utterance constituents. A fundamental principle that guides constituent ordering in adults has to do with information status, the accessibility of referents in discourse. Typically, adults order previously…

Recent research in semantics and pragmatics has revived the debate about whether there are two cognitively distinct categories of conversational implicatures: generalised and particularised. Generalised conversational implicatures are so-called because they seem to arise more or less independently of contextual support. Particularised implicatures…

Presents a computational study of children's acquisition of word-to-meaning mappings, approximates this task as a mathematical problem, and presents an algorithm for solving the problem, illustrating the algorithm's operation on a small example. Notes that computational simulations demonstrated the robustness of the algorithm and illustrated how…

Proposes a model for explaining constraints imposed by predicates on selecting arguments appropriate for the predicates. The model has two components, a taxonomic representation of concepts and probabilistic formalization of selectional constraints defined in terms of that taxonomy. Describes four computational experiments testing the model's…

An essential part of the human capacity for language is the ability to link conceptual or semantic representations with syntactic representations. On the basis of data from spontaneous production, Tomasello (2000) suggested that young children acquire such links on a verb-by-verb basis, with little in the way of a general understanding of…

This paper locates computational and behavioral studies of children's language learning in a theoretical framework; reviews four articles in this journal issue on learning word meanings and sounds and on setting grammatical parameters; highlights "autonomous bootstrapping" strategies that children use to represent uncertain linguistic…

Four- to 10-year olds viewed pictures in which all or some individuals pictured were doing something to all or some objects pictured. Children indicated which sentences, using "all" or "each" to modify the subject or object, applied to the pictures. In choosing the applicable sentence, children showed little difficulty with…

Explains distributional regularity (DR), an intuition that sound sequences occurring frequently and in multiple contexts are candidates for the lexicon. Describes study that proposed hypotheses about children's segmenting sounds using DR functions, exploiting phonotactic constraints on pronunciation, and learning word-boundary clusters. Details…

Three experiments investigated the nature of productive forward linking (from semantics to syntax) and productive reverse linking (from syntax to semantics) in language-impaired children. Found that the normally developing control subjects showed a good use of productive forward and reverse linking, whereas the language-impaired subjects…
