#RisingBilingualStar Children who learn another language before age five use the same part of the brain to acquire that second language that they use to learn their mother tongue. Younger learners are also uninhibited by the fear of making mistakes, which is sometimes an obstacle for older beginners.. Research also shows that learning a second language boosts problem-solving, critical-thinking, and listening skills, in addition to improving memory, concentration, and the ability to multitask. Children proficient in other languages also show signs of enhanced creativity and mental flexibility.
