Semantic Categorization in Portuguese-English Bilinguals

The main purpose of this study was to investigate the cross-linguistic interactions in the semantic categorization of late Portuguese-English bilinguals. The lexical items used in this study have a wider range of applications in one language and narrower in the other. Three types of categories were examined: classical, homophones, and radials. Late Portuguese-English bilinguals, as well as Portuguese and English monolinguals, were tested. After hearing a word, participants were asked to choose from a set of images, one that could be labelled as such. Analyses showed that when tested in English, participants performed better when it was the wider language. Participants’ performance was lower on classical categories than on homophone and radial categories.
