However, later evidence suggests that knowledge of more than one language may even improve cognitive flexibility
Additional benefits of being bilingual include metalinguistic awareness, more efficient learning strategies, heightened problem solving abilities, better creative thinking, and less anxiety than monolinguals. This paper aims to discuss and analyse in detail the phenomenon of bilingualism, its determinants, how it impacts communication, individual’s cognition and learning experience.
The ability to learn a language involves many areas of the brain. The association areas located in the parietal lobe with connections to the temporal and occipital areas are involved in language experiences by functionally facilitating a variety of language related behaviours such as vision, body awareness, touch, spatial orientation, verbal comprehension, localisation of objects in space, abstract and complex cognitive functions of mathematical reasoning and formulation of logical thoughts stemming from visual experiences (Lezak, 1997). This area of the brain was termed this association area in the parietal lobe as the “association area of association areas” while others named this association area the “heteromodal cortex” (Lezak, 1997). The right hemisphere is also involved when organising a narrative, an expression and during recognition of emotion in the tone of voice as well as regulation of rhythm and intonation of speech.
The specialisation of the left hemisphere in language processing, neuronal systems used for grammatical, semantic and lexical processing have been found to be affected by early language experiences (Carlson, 2001). Studies also indicate that right hemisphere involvement is present since much of the language processing requires spatial location, motion; and specialisation and differentiation of these neuronal
