The Netherlands – Study Shows Bilinguals Are Unable to ’Turn Off’ a Language Completely
19 August, 2009
With a vast majority of the world speaking more than one language, it is no wonder that psychologists are interested in its effect on cognitive functioning. For instance, how does the human brain switch between languages? Are we able to seamlessly activate one language and disregard knowledge of other languages completely?
According to a recent study published in Psychological Science, a journal of the Association for Psychological Science, it appears humans are not actually capable of “turning off” another language entirely. Psychologists Eva Van Assche, Wouter Duyck, Robert Hartsuiker and Kevin Diependaele from Ghent University found that knowledge of a second language actually has a continuous impact on native-language reading.
The researchers selected 45 Ghent University students whose native-language was Dutch and secondary language was English. The psychologists asked the students to read several sentences containing control words – plain words in their native-language – and cognates.
