A good deal of research purports that bilingualism has a positive effect on some aspects of cognitive functioning. However, this effect is not consistent, and little research examines trajectories of cognitive skill development in bilingual children. Moreover, it remains unclear whether different types of bilingualism impact how cognitive…

Purpose: This study examined bilinguals' performance on functional executive function map tasks such as the Zoo Map from the Behavioural Assessment of the Dysexecutive Syndrome and the extent to which working memory, set-shifting, and inhibition measures predicted bilinguals' performance on these tasks. Additionally, we explored the utility of…

The complicated cognitive processes involved in natural (primary) bilingualism lead to significant cognitive development. Executive functions as a fundamental component of human cognition are deemed to be affected by language learning. To date, a large number of studies have investigated how natural (primary) bilingualism influences executive…

Prior research has established an executive function advantage among bilinguals as compared to monolingual peers. These non-linguistic cognitive advantages are largely assumed to result from the experience of managing two linguistic systems. However, the possibility remains that the relationship between bilingualism and executive function is…

A study was designed to investigate the nature of language proficiency and its cross-lingual dimensions. The focus of the study was on the interdependence hypothesis, that older immigrant students whose first language (L1) cognitive/academic proficiency is better developed on arrival in Canada will acquire English cognitive/academic skills more…

Three experimental studies were carried out to examine the ability of groups of learners of English as a second language to solve problems of deductive reasoning (three term linear syllogisms) in their native and second languages. In the first study involving Canadian francophones studying English, subjects solved problems more effectively in…
