Birth-Kindergarten: Critical Years for Language Acquisition

Our ability to effortlessly absorb any new language begins to decline by age six.  
Recent publications from Cambridge University Press findings reveal "the procedural memory for language gradually decreases after about age 5."  

The latest research coming from world renowned researcher Patricia Kuhl, Ph.D., Co-director of The Institute for Learning and Brain Sciences at the University of Washington, finds that babies and young children learn language better than adults do.  Her research has led to the surge in popularity of language schools for babies and toddlers.

The Brain of Bilingual Children 

Researchers from University College London found that those who learned a foreign language at an early age later developed more advanced areas of gray matter - the area of the brain that processes information.  Similar to the way exercise builds muscle, foreign language exercises the brain.
