Uitkomstmaten
Primaire uitkomstmaten
The main endpoints of the study are to delineate the way cognitive control contributes to absence of standard language effect and reversed language effect in bilinguals, when producing L1 and L2 lexical items.
Achtergrond van het onderzoek
This research addresses the gap in the related state-of-the-art research, by investigating the way neural mechanisms function in bringing about reversed language effect, and absence of standard language effect in bilinguals, and the way cognitive control modulate such language behavior.
Doel van het onderzoek
- In bringing about an absence of standard language effect in bilinguals, the neural mechanisms which differentiate L1 and L2 lexical productions will no longer be different from each other and the same neural underpinnings will be involved in L1 and L2 lexical productions.
- In bringing about reversed language effect in bilinguals, cognitive control has a facilitatory function over L2 and an inhibitory function over L1. Such a function is also hypothesized to underlie lexical production in the intended language and the inhibition of such a production in the unintended language.
Onderzoeksopzet
This experiment is expected to be completed in mid 2018.

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
Participants will be healthy, volunteer, right-handed Dutch-English bilinguals, without any report and history of neurological or psychiatric problems and no counter-indications to MRI. Their age will not be more than thirty. In addition, in this study upper intermediate bilinguals will be included and the main criteria to assess this level of bilingualism will be a quick placement test published by Oxford University Press.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
Left-handed volunteers, balanced bilinguals, bilinguals with less than upper intermediate proficiency in English language, the ones who are more than 30 years old, and have any report and history of neurological or psychiatric problems will be excluded from this study. Potential participants will be pre-screened for contraindications for fMRI, which include metal implants, heart arrhythmia, claustrophobia, and possible pregnancy (in females). They will additionally be pre-screened for head trauma, history of neurological or psychiatric illness and/or use of psychotropic medications. The ones with the positive results in pre-screen section will be excluded.
