内容記述
The present study examined bidirectional learning transfer between joint and individual actions involving discrete isometric force production with the right index finger. To examine the effects of practice of joint action on performance of the individual action, participants performed a pre−test(individual condition), practice blocks(joint condition), and a post−test(individual condition)(IJI task). To examine the effects of practice of the individual action on performance during the joint action, the participants performed a pre−test(joint condition), practice blocks(individual condition), and a post−test(joint condition)(JIJtask). Whereas one participant made pressing movements with a target peak force of 10% maximum voluntary contraction(MVC)in the individual condition, two participants produced the target force of the sum of 10% MVC produced by each of them in the joint condition. In both the IJI and JIJ tasks, absolute errors and standard deviations of peak force were smaller post−test than pre−test, indicating bidirectional transfer between individual and joint conditions for force accuracy and variability. Although the negative correlation between forces produced by two participants(complementary force production)became stronger with practice blocks in the IJI task, there was no difference between the pre− and post−tests for the negative correlation in the JIJ task. In the JIJ task, the decrease in force error and variability during the individual action did not facilitate complementary force production during the joint action. This indicates that practice performed by two people is essential for complementary force production in joint action.
