Intrasentential codeswitching as conceptual projection of lemmas in the bilingual mental lexicon

Abstract

nature. The findings provide evidence that language-specific lemmas inthe bilingual mental lexicon are not equally activated during the process of ICS:activated lemmas of the Embedded Language (EL) (i.e., the guest language)which can be switched into the sentential frame of the Matrix Language (ML)(i.e., the base or host language). The naturally occurring ICS instances discussedin this paper also provide evidence that there is differential activation ofparticipating languages in ICS in terms of language-specific lemma activationfor content morphemes, and language-specific lemma activation forsufficiently congruent with ML counterparts at several levels for possible ICSrealizations. This paper proposes a bilingual lemma activation model of ICS.Journal of Cognitive Science 6: 149 - 179, 2006.ⓒ2006 Institute for Cognitive Science, Seoul National University.
