We report an experiment in which subjects named 120 pictures, consisting of series of five pictures drawn from each of 24 semantic categories (and intermixed with 45 fillers). The number of intervening trials (lag) between successive presentations of members of the same category varied from two to eight. Subjects' naming latencies were slowed by…

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…

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…

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…

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…
