As adults we can easily distinguish when we hear words spoken in a different language, but could we tell the difference just by looking at the lips of the person speaking. Amazingly there are new studies that show babies as young as 3 months old can do just that. Babies were shown a silent video clip of an adult who is fluent in two languages repeating the same sentence in only one language. After the child’s reaction to the video was consistant, the baby was shown the same adult saying the same sentence but this time in another language, the baby’s reaction was one of curiosity and intensity. Child psychologists agree that the results of this testing proves that infants are born with an ability to indentify and relate to "visual speech". These test results also aid experts in understand the relationship between language & brain development.
