Self‐rated right‐left confusability and objectively measured right‐left discrimination

Normal, intelligent young adult men and women, grouped according to handedness, were compared with regard to self‐rated right‐left confusability and performance on three objective measures of right‐left discrimination, the Right‐Left Orientation Test (RLOT), Laterality Discrimination Test (LDT), and Left‐Right Reorientation Test (LRRT). Men were found to rate themselves as less susceptible to right‐left confusion and to more quickly but no less accurately make right‐left discriminations than women. Handedness did not affect right‐left confusability ratings, the accuracy of right‐left discriminations, or overall LRRT speed but did weakly affect LDT speed. Left‐handers tended to respond more quickly than right‐handers. Analyses of response latencies to different LRRT figural orientations indicated that male superiority was greater for inverted than upright figures but also applied to self‐oriented and upright figures alone. These results have implications for understanding the multidimensionality of right‐l...
