Research confirms that learning a second language before age five significantly alters the brain’s structure. According to the Society for Neuroscience, increased brain activity is so prominent and predictable that neurologists can identify bilingualism from a brain scan. The cognitive benefits include reading proficiency, increased comprehension, greater flexibility in thinking, improved listening and problem-solving skills. The belief that learning two languages might confuse or delay young learners has been consistently disproved. Rather, new studies show that learning two languages before the age of 5 gives children the ability to scaffold fundamental skills and apply them to both languages.
