Handedness is related to lateralization of behavioral skills and differences in structure and function in motor system. The aim of this research is to study the bilateral transfer of learning between the right- and left-handers during the process of transfer from the dominant to non-dominant hand and vice versa. Participants were undergraduates of Payam-e Noor University of Andimeshk in the academic year 2009-2010. 30 left-handers (13 females and 17 males) and 42 right-handers (17 females and 25 males) were randomly selected and placed in two conditions: the transfer from dominant to non-dominant hand and non-dominant to dominant hand. Chapman's handedness questionnaire was used to identify the left- and right-handers. In addition, mirror drawing apparatus was used to measure the learning transfer. The data were analyzed using multivariate analysis of variance method. Results showed a meaningful difference in learning transfer between the two conditions. The average number of errors committed and the time spent by left- and right-handers in the process of transfer from dominant to non-dominant hand were less than the errors they committed and the time they spent in the second condition. In addition, learning transfer occurred at a faster rate in the first condition. The analysis also revealed that the left-handed and right-handed students showed no meaningful difference in learning transfer rate. In sum, skill learning is transferred from dominant organs to non-dominant ones.
