Critical Period Hypothesis

For many centuries, the human card has been somewhat of an enigma, especially

within the disciplines of biology and linguistics. The relationship in the midst of the instinct and

langauage has prompted scientists and researchers to study about where language

originates in the flair. Researchers have also directed their help to how certain

neurological deficits or dis monastic orders directly affect language. As a result of this research,

one of the great findings is that language is lateralized to the odd hemisphere of the brain.

The critical period hypothesis and the experimental present provided by dichotic

listening support the theory that language exists in the left hemisphere.

In essence, the critical period hypothesis contends that the capacity to learn a

language is limited to the years between birth and somewhere around the age when a

barbarian enters puberty. These children can more easily acquire language than post-

pubescent children, to whom this ability disappears and is most probably a result of the

brain maturing. The foundation of the critical period hypothesis rests on neurological

research that suggests that brain functions become lateralized after puberty. As we have a go at it

there argon two hemispheres of the human brain- the regenerate and the left.

functions appear to be controlled or stationed in the right hemisphere, while others are

located in the left portion. well-nigh evidence suggests that the right hemisphere plays a role

at the earliest stages of language acquisition (Fromkin 2007). Nevertheless, language

functions for the most single-valued function are specialized in the left hemisphere. Before puberty, it is

believed that these functions are not completely assigned to either portion of the brain.

The brain is viewed as elastic. The specific assignment or lateralization of brain

functions is believed to be complete and set sometime during or scarcely after puberty.
