Lexical interference in the recall of adult Finnish/Swedish bilinguals with Finnish dominant is studied. The error patterns of short-term recall of words presented by category in either Swedish or Finnish were examined for translations, lexical substitutions, and intrusions or false recalls of non-occurring words. Individual differences in fluency, education, and task demand were also considered. The results suggest meaningful connections between interference and word category and between interference and fluency as measured by correctly retrieved words. They support bilingual interdependence rather than independence, but do not suggest a unidirectional error pattern (e.g., consistently occurring in the shift from one language to the other). Several tables are included. (MSE)
