Bilingual retrieval from semantic memory

Bilinguals produced English and French words from two taxonomic categories. Analyses of outputs indicated they retrieved words by semantic category, but in clusters from the same language, half the subjects immediately translating the words retrieved. Translations aside, more shifts were across languages than across categories. Protocols also showed the same degree of semantic clustering and number of concepts retrieved as those of other bilinguals responding unilingually. The findings are consistent with separate lexicons for each language, tapping a common system of concepts. An alternative account is possible in terms of a single lexicon, organized along semantic lines, but with stronger links between words from the same language.
