Resumen
Switching between languages requires the participation of executive functions (EFs) which comprise both the ‘hot’ affective aspects (hot EFs) and the ‘cool’ cognitive aspects (cool EFs). However, the role of these EFs in language switching is not clear. This study employed a word valence categorization task to explore the effects of hot (i.e. emotional valence and emotional congruency) and cool (i.e. inhibitory control ability, IC ability) EFs on high- and low-IC Chinese-English bilinguals’ language switching costs. The results showed smaller language switching costs for positive than negative emotional words, for emotional incongruent than congruent trials, for positive than negative emotional words in emotional congruent trials and for negative emotional words in emotional incongruent than congruent trials. Moreover, hot and cool EFs worked interactively, with larger language switching costs for negative emotional words and the same pattern in emotional congruent trials for high-IC participants over low-IC ones. These results indicate that various aspects of hot EFs affect language switching costs individually and interactively, while also modulate the effects of cool EF on language switching costs during Chinese-English emotional word comprehension. These findings have implications for extending the Bilingual Interactive Activation plus (BIA+) model by incorporating both hot and cool EFs.
