Processing of inflected nouns in late bilinguals

This study investigated the recognition of Swedish inflected nouns in two participant groups. Both groups were Finnish-speaking late learners of Swedish, but the groups differed in regard to their Swedish language proficiency. In a visual lexical decision task, inflected Swedish nouns from three frequency ranges were contrasted with corresponding monomorphemic nouns. The reaction times and error rates suggested morphological decomposition for low-frequency inflected words. Yet, both medium- and high-frequency inflected words appeared to possess full-form representations. Despite an overall advantage for the more proficient participants, this pattern was present in both groups. The results indicate that even late exposure to a language can yield such input representations for morphologically complex words that are typical of native speakers.
