This paper sketches a comprehensive framework for modeling and interpreting language contact phenomena, with speakers' bilingual strategies in specific scenarios of language contact as its point of departure. Bilingual strategies are conditioned by social factors, processing constraints of speakers' bilingual competence, and perceived…

Children acquiring their first languages are frequently regarded as the principal agents of diachronic change. The causes and the precise nature of the processes of change are, however, far from clear. The following discussion focuses on possible changes of core properties of grammars which, in terms of the theory of Universal Grammar, can be…

This article reports the results of an experiment on production of "his/her" in English as a second language (L2) by proficient native speakers of Italian, Spanish, and Dutch. In Dutch and English, 3rd person singular possessive pronouns agree in gender with their antecedents, in Italian and Spanish possessives in general agree with the noun they…

Studies of copular forms are extremely relevant to issues in philosophy, psychology, and linguistics. Psychologists have recently argued that the most distinctive aspect of human language is its combinatorial nature (e.g., Gentner, 2003; Spelke, 2003). They argue that this linguistic component might be what separates human from animal cognition.…

The five papers in this issue cover a range of perspectives on the acquisition and use of the Spanish copulas "ser" and "estar" in a variety of contexts, including language contact, bilingual language acquisition, and classroom second language learning. The fact that these papers cite work in this area as far back as the early part of the 20th…

The paper offers a model of language development, first and second, within a processing perspective. We first sketch a modular view of language, in which competence is embodied in the processing mechanisms. We then propose a novel approach to language acquisition (Acquisition by Processing Theory, or APT), in which development of the module occurs…

Examines whether an individual's linguistic knowledge, either as a speaker of a particular language or as a bilingual, influences theory of mind development. Three- and four-year-old English monolinguals, Mandarin Chinese monolinguals, and Mandarin-English bilinguals were given appearance-reality, perspective-taking, and false-belief tasks.…
