Several studies have shown that concepts spread activation to words of both of a bilingual's languages. Therefore, a central issue that needs to be clarified is how a bilingual manages to restrict his speech production to a single language. One influential proposal is that when speaking in one language, the other language is inhibited. An…

In this article we discuss different views about how information flows through the lexical system in bilingual speech production. In the first part, we focus on some of the experimental evidence often quoted in favor of the parallel activation of the bilinguals' two languages from the semantic system in the course of language production. We argue…

The authors report 4 experiments exploring the language-switching performance of highly proficient bilinguals in a picture-naming task. In Experiment 1, they tested the impact of language similarity and age of 2nd language acquisition on the language-switching performance of highly proficient bilinguals. Experiments 2, 3, and 4 assessed the…

How does lexical selection function in highly-proficient bilingual speakers? What is the role of the non-response language during the course of lexicalization? Evidence of cross-language interference was obtained by Hermans, Bongaerts, De Bot and Schreuder (1998) using the picture-word interference paradigm: participants took longer to name the…
