Semantic priming effects and lexical access in English as L3

We report an experiment using a picture-naming task within the masked priming paradigm to examine lexical access in English as a third language. Participants were assigned to one of three groups: a control group, consisting of native speakers of English, and two experimental groups, one consisting of speakers of English as L2 and the other consisting of speakers of German as L2 and English as L3. Participants of the two experimental groups were native speakers of Brazilian Portuguese. All participants performed a picture-naming task in English in which pictures were preceded by a masked prime word in the target language (English), in the native language (Brazilian Portuguese) or in the second language (German). The results indicate some interference from the participants' second language in the production of their third language (English), favoring the view that lexical access of multilinguals is qualitatively different from that of bilinguals and monolinguals.
