In today’s increasing globalized world, speaking more than
one language can create job opportunities, facilitate travels and many more. However, practical benefits aside, there is
ample evidence from research that demonstrates the profound effects of
linguistic diversity.
Contrasting the predominant assumption that introducing multilingualism
in children could hinder intellectual development, collective evidences from a
number of studies have shown that the interference can in fact strengthen
cognitive abilities. Among many, one key difference between monolinguals and
multilinguals is the heightened ability in the brain’s executive function. Having
to switch between languages often, the process trains the brain to be highly
attentive and efficient while performing mentally demanding tasks. Even when
only one language is used, the brain persistently stays alert. As a result,
those who speak multiple languages display increased concentration, better
memory, and superior decision making skills by focusing on pertinent facts while
disregarding irrelevant information.
An exceptional performance to mental flexibility is of
course appreciated but the most appealing benefit of linguistic diversity
occurs later in life. In a research led by neuropsychologists from the University
of California, San Diego, bilingual experiences measured greater resistant to
onset of dementia and symptoms of Alzheimer’s disease when compared to their monolingual
counterparts. It appears that the higher the proficiency, the better the
protection against cognitive decline. This goes to show that mastering multiple
languages offers benefits that go beyond the obvious. Perhaps, multilingualism’s
incredible side effects could serve as a motivation to acquire a new language!
