Evaluation of learning and transfer of complex bimanual task asymmetrical in combination of features of speed, effect of gravity and amplitude of movement

The aim of this study was the evaluation of learning and transfer of asymmetric bimanual complex tasks in combination of features of speed, gravity and amplitude. The instruments used in this study included pen Mouse, laptop, special glove and metronome. The subjects of the research were eight grade, right-handed students (mean age, 14.2±0.13) of Shahid Ebrahimi school of Ahvaz, who had no familiarity with desired skill. The subjects voluntarily participated in the study and randomly and evenly into three groups, the first group(n=10), second group(n=10) and the third group(n=10). Three test groups have performed the asymmetric bimanual task in two ways difficult task with the dominant hand (training task) as well as a difficult task with non-dominant hand (transfer task), in pre-test and post-test. The movement patterns of two hands were different from each other in movement features (first group: direction and velocity pattern, second group: velocity pattern and effect of gravity, third group: amplitude and effect of gravity). Each of the test groups after the practice run for three days and then tests were performed. The results showed that in first group, transfer to vice versa pattern is positive. However, in second group, there is a positive transition and the transition is zero, and in third group, transfer to vice versa pattern is negative. Seems interpretations that are made on the basis of the hierarchical theory should be considered more than two levels of control bimanual movements, In other words, different levels of difficulty of the task.
