Abstract
Left-, mixed-, and right-handed teach n = 10, N= 30) adolescent boys who we re classified on the basis of a hand preference inventory performed a mirro r-drawing task with a bilateral transfer of a skill paradigm. Participants' hand preference and the magnitude of bilateral transfer of skill were asse ssed in terms of errors committed and time taken to complete the mirror-dra wing task. Mixed-handed participants exhibited significantly less habit int erference for mirror drawing, and they performed the task significantly fas ter than the left-handers did; the group difference was not significant for the frequency of errors committed. These groups did not differ in terms of the magnitude of bilateral transfer of skill; the trend, however, showed t hat the transfer of skill was minimum in mixed-handers. These findings exte nd the theory that mixed-handed participants' inability to transfer motor s kill from one hand to the other could be attributable to their lack of a cl ear pattern of lateralization. Their ability to perform well either at init ial or later trials may be a function of less interference from their norma l motor habits.
