Can You Teach Yourself to Roll Your Tongue?
According to a study published in the Journal of Clinical & Diagnostic Research, the language you speak is a factor in tongue movement and the ability to roll your tongue. The study included 450 medical students in Malaysia. They came from three ethnic groups (Malay, Malaysian Chinese, and Malaysian Indian). They spoke several different languages.
The study found that Malaysian Indians were more versatile with tongue movements than the Malays and the Malaysian Chinese groups. The conclusion reached was that making certain tongue shapes and movements depended on an individual’s language's lingual demands. So a person whose language engaged the most tongue movements had a leg or, in this case, tongue up in being able to learn how to make different shapes.
So what do you think? Are you thinking of taking up tongue-twisting, rolling, cloverleaf making training so you can be the life of the party? Start practicing. If you speak a language that involves many tongue movements, the odds are in your favor!
