All individuals were classified as either right or left-handed based on a modified version of the Edinburgh Inventory. The total number of right and left hand items was scored and the laterality quotient was computed: (Total R − Total L)/(Total R + Total L) yielding a range from +1.00 (totally dextral) to −1.00 (totally nondextral).
