Criticism of the Critical Period Hypothesis

CRITICAL Critical Period PERIOD Ducklings after hatching L2 Acquisition for L2 morphology and syntax to reach native levels exposure to the L2 must begin before age 15 1) attaining to native-like levels of proficiency 2) More concious effort than in earlier L2 acquisition

Effortfulness of later language learning Breathnach,1993 claims that the infant learns to pronounce and use the language he hears around him with ease and perfection while adult L2 learning demands a systematic and determined effort.

If so, lateralization cannot be the evidence of the critical period.

Therefore, the results of this study did not support its hypothesis that the rate that a person learns a second language is inversely related to the age of that person. On the contrary, the results of this study showed that there is a direct relationship between the age of a person and the rate that he acquires a second language. Overall, this study does not support the widely accepted critical period hypothesis.
