Words have meanings vastly undetermined by the contexts in which they occur. Their acquisition therefore presents formidable problems of induction. Lila Gleitman and colleagues have advocated for one part of a solution: indirect evidence for a word's meaning may come from its syntactic distribution, via syntactic bootstrapping. But while formal…

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child-directed speech to create quantitative features representing natural variability in word contexts. We…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

A set of predictions based on Reinhart's (1986) Theory of Relevance are evaluated against published results of tests of Binding Theory. Relevance Theory provides a means of understanding constraints on testing syntactic knowledge. Pragmatic factors must be systematically controlled in any evaluation of syntactic knowledge. (Contains 22…

Notes that in a typical word monitoring paradigm, subjects monitor ongoing language input for a pre-designated target word and that independent variables include the nature and position of the target word and the context in which it is embedded. Also notes that forms of this task are suitable for studies with young children and with individuals…
