Bilingual language control across modalities
The relationship between mixed-language comprehension and production
Bilingual language control has previously been tested separately in tasks of language comprehension and
language production. Whereas these studies have suggested that local control processes are selectively recruited during
mixed-language production, the present study investigated whether measures of global control show the same dependence on
modality, or are shared across modalities. Thirty-eight Dutch-French bilingual young adults participated by completing two
tasks of bilingual language control in both modalities. Global accuracy on mixed-language comprehension was related to mixing
costs on bilingual verbal fluency, but only when compared to the L2-baseline. Global performance on mixed-language production
was related to forward (L1-to-L2) switch costs. Finally, a significant correlation was found between the mixing cost on verbal
fluency and forward switch costs on the comprehension task. The results are interpreted as evidence for the involvement of
monitoring processes in bilingual language control across modality. The results also highlight the relevance of language
switch directionality.
