According to a recent study conducted by University of Haifa researchers, if you speak two languages, you probably have a more agile brain than those who speak only one.
The scientists were attempting to understand why bilinguals take much longer than monolinguals to react to audible cues yet demonstrate more subcortical brain activity than those who only speak one language.
“The synchrony between neural and cognitive-perceptual measures makes the research unique and reveals direct brain-behavior links, serving as the basis for a fuller understanding of bilingual speech perception in challenging listening conditions,”
“The effects of bilingualism on speech perception in noise are widely studied, few studies to date have compared bilingual-monolingual performance when all participants are operating in their dominant language.”
