60 right-handed college students classified as preferring either a style of left or right hemisphericity mirror-traced a star pattern once with each hand. Speed of tracing and number of deviations outside the star pattern were the dependent measures. Analysis showed no statistically significant differences in performance between right- and left-style groups or between men and women. However, subjects classified as showing a right-hemisphericity style mirror-traced the star pattern significantly faster and more accurately with the left hand than with the right. The left-hemisphericity-scoring group displayed a nonsignificant tendency to perform better on the reverse pattern.
