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.
