A study was conducted to examine the actual frequency and distribution of intermanual differences on several motor tasks. In addition, the relationships of age, sex, and education were examined in a sample of 365 nonclinical subjects. There was no consistent relationship between age, educational level, and the difference scores and there were small but significant effects for sex. The distribution of scores essentially confirmed generally used guidelines for evaluation of intermanual differences, but most importantly revealed that a significant proportion of cases exhibited "atypical" patterns of performance. These findings are discussed in regard to previous studies and the implications for interpretation of intermanual differences in motor performance.
