Which words are activated during bilingual word production?

Abstract

Whether words are or are not activated within the lexicon of the nonused language is an important question for accounts of bilingual word production. Prior studies have not led to conclusive results, either because alternative accounts could be proposed for their findings or because activation could have been artificially induced by the experimental paradigms. Moreover, previous data only involved target translations, and nothing is known about the activation of nontarget words in the nonused language. The picture-picture interference paradigm was used here, since it allowed the activation of nontarget words to be determined without showing stimuli that could artificially activate the nonused language. Proficient Spanish-Catalan speakers were presented with pairs of partially overlapping colored pictures and were instructed to name the green picture and ignore the red picture. In Experiment 1, distractor pictures with cognate names interfered more than distractor pictures with noncognate names. In Experiment 2, facilitation was observed when the names of the distractor pictures in the nonused language were phonologically related to the names of the target pictures. Overall, these results indicate that nontarget words are activated in the nonused language, at least in the case of proficient bilingual speakers. These results help researchers to constrain theories of bilingual lexical access. (PsycINFO Database Record (c) 2009 APA, all rights reserved).
