Left-handedness and tongue-rolling ability

Percept Mot Skills. 1988 Aug;67(1):168-70. doi: 10.2466/pms.1988.67.1.168.


948 undergraduates at The Ohio State University were administered the 10-item Edinburgh Handedness Inventory and asked to indicate the extent to which they could turn up the sides of their tongues. Significantly fewer left-handers than right-handers (62.8% and 74.8%, respectively) reported being able to turn up either or both sides. Sex differences in tongue-rolling ability were also noted. Among the 403 men included in the final sample, 77.4% could roll their tongues, whereas only 69.7% of the 491 women could do so.
