the scientific aspect
The scientist Paul Broca discovered in 1861 that a particular area in the brain was dedicated to language acquisition
Professor Jean Petit Discovery
After more than 35 years of research, Jean Petit, a French psycholinguist, along with American scientists, established that:•The best age to learn a second language is between 0 and 7 years. •Up to 5 languages can be learned during that period. •Discrimination between sounds is very easy for young children without making any mistake. •The learning process at that age is compared to a TVG (fastest train ever) •After 7, the learning process slows down. • At 13, the articulation and sound production mechanism (phoneme and allophone) are programmed on monolingual mode (this is why adults have trouble learning a second language). • Canadian researchers have found an average of 14 points difference in IQ between a bilingual and a monolingual student. • Writing and reading with the same alphabet is easier. •Mathematics and music skills are enhanced by learning a 2nd language.
