“…Two different bilingual populations were recruited because it has been demonstrated that parallel language activation is constrained by language proficiency. High proficiency boosts parallel language activation, whereas lower proficiency in one of the languages generates asymmetrical language activation patterns (e.g., Blumenfeld & Marian, 2007;Brysbaert, Lange, & Van Wijnendaele, 2000;Costa & Santesteban, 2004;Grosjean, 1998;Weber & Cutler, 2004). Consequently, if participants in Experiment 1 but not in Experiment 2 show interlocutor identity related congruency effects, then the observed effect is likely related to the bilinguals' mental control over parallel language activation.…”
