Thesis Title

The effects of code-switching on executive functioning in early and late bilinguals

Research Project

I am interested in how daily use of two or more languages affects non-linguistic cognitive abilities. Prior research has shown that bilinguals often outperform their monolingual counterparts in tests of executive function such as the Simon task, however the origin of these cognitive benefits is not well established.

It is believed that this may occur because bilinguals have extensive experience, not just with using more than one language, but also with switching between those languages. However, language experience of bilinguals is diverse. While some may, for example, speak one language at home and the other at work, others may switch between their languages in a single context, speaking predominantly in one language with interspersed words or phrases from the other language (code-switching).

My thesis aims to investigate whether cognitive abilities differ between bilinguals who code-switch more often compared to those who do so less often, and whether these effects depend on the age at which the second language is acquired.
