The elusive link between language control and executive control: A case of limited transfer
Year: 2013
Type: article
Abstract: We investigated the relationship between language control and executive control by testing three groups of bilinguals (104 participants) and 54 monolinguals in a training and transfer paradigm. Participants practised either a language or a non-linguistic colour/shape switching task and were tested one week later on both tasks. The colour/shape task produced significant immediate improvement with training, which was maintained one week later, but exhibited no cross-task transfer effects. In the dominant language, training effects did not persist after one week, and there were no transfer effects. In the non-dominant language there were significant training effects that lasted one week, and there was also transfer facilitation from prior practice with the colour/shape task, which was limited to a reduction in mixing costs. Despite limited transfer, there were significant correlations between tasks in mixing costs for bilinguals, in switching costs for monolinguals, and in intrusion errors for all participants. Finally, the pattern of costs observed for the two tasks exhibited both similarities and differences across participants. These results imply a limited but significant role for executive control in bilingual language control, possibly playing a stronger role in facilitating non-dominant-language production and in supporting the ability to monitor response outcomes to avoid errors.
