Abstract

Background: While there is evidence in support of a bilingual advantage in executive function in children and adults, little work supports these effects in young people. This lack of support may result as consequence of a developmental ceiling effect on task performance in this age group. An alternative explanation can be found in the treatment of bilingualism as a categorical variable, and the use of exclusively fixed-effects methods of analysis. These methods treat bilinguals as a homogenous group, ignoring nontrivial differences between participants, and may contribute to this lack of evidence. This scoping review aims is to identify and summarize research practices in the investigation of bilingual effects in inhibition and attentional function in young people.

Methods: The proposed scoping review will follow the five-stage framework proposed by Arksey and O’Malley (2005). Searches will be conducted across five databases using inclusive search strings. Study selection will follow the guidance of the PRISMA-ScR checklist. This review will include both published and unpublished work. A standardized data extraction spreadsheet will be used and data will be presented in tabular and graphic format in alignment with the objectives of the review.

Discussion: This review aims to provide a current understanding of research practices in the investigation of bilingual effects in young people as well as identify gaps in the literature. This review may also draw attention to methodological trends in the current literature that limit the conclusions researchers can draw.
