BILINGUALISM AND ITS IMPACT ON COGNITION 2
As per the research conducted by Marian and Shook on cognitive advantages of being
bilingual, most individuals in the world normally speak two or more languages compared to
individuals who speak only one language. In most cases, the capacity to speak more than one
language is considered to have more advantages particularly in terms of changing our brain
structure. One of the advantages of being bilingual is that it enables one to manage conflicts,
enhance sensory processing, as well as increase decision-making functioning (Wilson, 2016, p.
67). On the other hand, the disadvantages of being bilingual are that it may cause one to have a
lower vocabulary and become slow in recalling words.
Ideally, the initial benefit of being bilingual is that those who can speak two languages
are better at managing conflicts. For instance, in case an individual sees the word RED yet, it is
written in a blue colour they will be able to quickly recognize the colour as blue than individuals
who are not bilingual (Zahodne & Manly, 2014, P. 56). Normally, for bilingual individuals the
conflict management capability reveals itself in their daily activities, for instance, while choosing
what to eat, wear, or how to react to a certain situation. Another advantage of being bilingual is
that it enhances sensory processing. Notably, when individuals who speak more than one
language hear a simple speech in a noisy place, they normally have a greater neural response
than individuals who only speak one language. This implies that bilingual individuals precisely
have more activities in their brain compared to monolingual individuals. Subsequently, being in
a position to speak more than one language enhances executive functioning. In this case, the
prefrontal cortex is regarded as the part of the brain which is in control of the executive
functioning, and particularly this region is improved in bilingual individuals. Significantly, this
implies that individuals who can speak more than one language are capable of switching between
their daily tasks and distractors (Wilson, 2016, p. 82).
