Накратко на български

Механизмите за потискане на единия език при двуезичните хора се изследват чрез това колко трудно е да се върнеш към първия език след използване на втори. Това помага да се разбере как мозъкът управлява конкуренцията между два езика при голяма част от населението.

Bilingual inhibitory control: N-2 language repetition costs unchained

According to bilingual research, language selection is the principal challenge for the bilingual mind, as both languages are typically activated in parallel, and thus compete with one another. In the present project, we investigated whether inhibition is involved as a crucial underlying mechanism for the resolution of this cross-language competition in production and comprehension, as suggested by several models (e.g., Green, 1998). Prior research has provided evidence that bilingual inhibitory control is implemented, which is in line with several bilingual models, but these measures can typically also be explained without inhibition (for a review, see Declerck & Philipp, 2015). In the current proposal, we mainly relied on a marker of bilingual inhibitory control that can only been explained with inhibition, but that has not yet been investigated extensively, namely n-2 language repetition costs. More specifically, we set out to investigate whether there is bilingual inhibitory control during production and comprehension using this measure, and whether the bilingual process is persisting (i.e., continues into the next words) and/or reactive (i.e., more inhibition is required for more active languages). In this project, we found evidence for persisting inhibitory control during production, but the evidence for comprehension shows that this is not always the case. We also found evidence for reactive inhibitory control, but the evidence showed an opposite pattern of what most models assume: lesser activation of the non-target language leads to more inhibition of this language. This line of research is important on a societal level for several reasons. First off, because more than half world’s population is proficient in two or more languages (Grosjean, 2010), this project allowed us to gather knowledge on how language processing occurs for most people. Another reason is that a better understanding of the language control process will also lead to a better understanding of bilingual aphasic patients, who pathologically switch languages.

Цел на проекта

A multitude of models have proposed different mechanisms underlying bilingual language control, a process that restricts bilingual language processing to the target language. Many, but not all, of these models assume that inhibition plays an integral role during bilingual language control. However, there is little empirical evidence for such a claim. In the current proposal, a list of 8 experiments are put forward that investigate, in both production and comprehension, whether there is inhibition and whether this inhibition persists and is reactive, as proposed by several models. Moreover, the current proposal also allows for an investigation into the locus of inhibitory control, which is a largely neglected subject. To investigate inhibition, n-2 language repetition costs would be examined, which entail worse performance on language A in ABA than in CBA sequences (with A, B, and C being trials in different languages). Finally, based on a previous comprehension-based computational model of language control (BIA-model) and the data obtained in the current proposal, a computational model of inhibitory control during bilingual language production would be constructed, which is novel in the field.
