Abstract: Research in the past few decades has generally supported a nonselective view of bilingual lexical access where a bilinguals' two languages are both active during monolingual processing. However, recent work by Costa et al., 2016, has brought this into question by reinterpreting evidence for nonselectivity in a selective manner: bilinguals are capable of activating their target language ... read morewithout simultaneous activation of the nontarget language due to the bilingual organization of the second language (L2) during learning. This dissertation manipulated the factor of first language (L1) attrition in two event-related potential (ERP) experiments to disentangle Costa and colleague's selective processing proposal versus the traditional nonselective processing view of bilingual lexical access. In Experiment 1, Spanish-English bilinguals demonstrated an N400 effect of L1 attrition during implicit L1 processing in an L2 semantic judgment task, indicating the contribution of variable L1 lexical access during L2 processing. A follow-up experiment indicated that this effect was due to L1 lexical properties, confirming the presence of L1 processing during L2 processing. These results are incompatible with Costa and colleagues' selective view, adding to the literature supporting a nonselective view of bilingual lexical access.
