There is a growing body of evidence showing that conversational implicatures are rapidly accessed in incremental utterance interpretation. To date, studies showing incremental access have focussed on implicatures related to linguistic triggers, such as "some" and "or". We discuss three kinds of on-line model that can account for this data. A model…

Why do adult language learners typically fail to acquire second languages with native proficiency? Does prior linguistic experience influence the size of the "units" adults attend to in learning, and if so, how does this influence what gets learned? Here, we examine these questions in relation to grammatical gender, which adult learners almost…

How recurrent typological patterns, or universals, emerge from the extensive diversity found across the world's languages constitutes a central question for linguistics and cognitive science. Recent challenges to a fundamental assumption of generative linguistics--that universal properties of the human language acquisition faculty constrain the…

There is much debate over the degree to which language learning is governed by innate language-specific biases, or acquired through cognition-general principles. Here we examine the probabilistic language acquisition hypothesis on three levels: We outline a novel theoretical result showing that it is possible to learn the exact "generative model"…

Previous work demonstrated that 9-month-olds who were familiarized with 3-syllable strings consistent with both a broader (AAB or ABA) and narrower (AA"di" or A"di"A) generalization made only the latter. Because the narrower generalization is a subset of the broader one, any example that is consistent with the broader generalization but not the…

Recent work on the acquisition of number words has emphasized the importance of integrating linguistic and developmental perspectives [Musolino, J. (2004). The semantics and acquisition of number words: Integrating linguistic and developmental perspectives. "Cognition 93", 1-41; Papafragou, A., Musolino, J. (2003). Scalar implicatures: Scalar…

To learn a language, speakers must learn its words and rules from fluent speech; in particular, they must learn dependencies among linguistic classes. We show that when familiarized with a short artificial, subliminally bracketed stream, participants can learn relations about the structure of its words, which specify the classes of syllables…

Is the structure of lexical representations universal, or do languages vary in the fundamental ways in which they represent lexical information? Here, we consider a touchstone case: whether Semitic languages require a special morpheme, the consonantal root. In so doing, we explore a well-known constraint on the location of identical consonants…

Kean (EJ 165 107) presented a linguistic model to account for the features of the syndrome of Broca's aphasia, especially their agrammatism. This paper critiques Kean's paper by describing and evaluating her five major arguments. It is concluded that Kean's phonological model cannot account for agrammatism as well as syntactic models can.…

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…

Details findings indicating that most early linguistic competence is item based. Maintains that language development proceeds without evidence of system-wide syntactic categories, schemas, or parameters. Suggests that findings are not easily explained by the development of children's skills of linguistic performance, pragmatics, or other external…

The human sentence parsing device assigns phrase structure to sentences in two steps. The first stage parser assigns lexical and phrasal nodes to substrings of words. The second stage parser then adds higher nodes to link these phrasal packages together into a complete phrase marker. This model is compared with others. (Author/RD)

The justification for Kean's (EJ 165 107) analysis of agrammatism as a phonological disorder rests on a certain specific theory of the structure of human language faculty, which is summarized. Simply proposing a competing analysis based on a distinct theory does not falsify the hypotheses. However, Kean's claims are subject to empirical…

Examines the role of common ground between speakers in production of utterances. Outlines two models, and compares them by contrasting the use of common ground between speakers and listeners as evidenced by physical copresence. Results suggest speakers do not employ audience design in the initial planning of utterances, but do monitor initial…

In some psycholinguistic models, processing is characterized by generation of multiple outputs using information from higher processing levels. Such models are considered autonomous in word recognition domain but interactive in sentence processing domain. This confusion arises not from differences between lexical and syntactic processing, but from…
