Abstract：
:Among 1848 young men appearing before the Danish draft board, 232 (13%) were left-handed. Of these, 118 (51%) used an inverted, or hook-like, writing posture, 49 (21%) used a non-inverted posture and the remaining 65 (28%) could not be categorized. There were no differences between left- and right-handers on a battery of four cognitive tests. However, inverted left-handers performed significantly or near-significantly better than the non-inverted left-handers on two of the four tests and significantly better on the total score for the test battery. These results support the contention that the inverted posture is adaptive for left-handers and suggest that it may be more likely to be adopted by those with better cognitive abilities. Our findings conflict with earlier reports from two decades ago, however, and the association may therefore be socially and culturally dependent.
