It is my belief that it is easier for adults to learn a second language than it is for a child. Adults have advanced cognitive developments and are able to learn better as a result as it applies to second langue acquisition. In the myths book, studies have found that is takes adults 10,000 hours to acquire a skill to the level of expert, whereas the child requires 17,520 hours of input in order to become a proficient speaker of the language. It only seems that the child learns more quickly, because the type of language we expect from a child and an adult are so different. The only real advantage to learning a language as a child is the ability to develop more native like pronunciations. In the brain- based research power point the author questions native level of acquisition as a goal, rather the goal should be high levels of proficiency. This is supported by the brain-based research that high proficient bilinguals connect their L2 lexicon directly to concepts. Where as, low proficient bilinguals process L2 lexicon through L1 lexicon. This implies that a high level of proficiency is beneficial for the brain to process efficiently.
