本研究探讨了任务限制对动作学习的影响，并考虑了速度与准确性的关系。在实验中，参与者连续五天练习基于自主性的运动。参与者参加了时间最小化或时间匹配限制的培训。结果表明，在训练情境中，速度-准确性的权衡不明显或很弱。当参与者在时间最小化的约束下练习动作时，动作错误没有变化，而动作时间减少了。在时间匹配约束下，误差随着会话的进行而减小。这些结果进行了讨论的信号相关噪声和探索性搜索噪声的组合。这表明，更新的空间和时间因素似乎并没有同时发生在运动学习。
This study investigated the influences of task constraint on motor learning for a trajectory-based movement considering the speed–accuracy relationship. In the experiment, participants practiced trajectory-based movements for five consecutive days. The participants were engaged in training with time-minimization or time-matching constraints. The results demonstrated that the speed–accuracy tradeoff was not apparent or was weak in the training situation. When the participants practiced the movement with a time-minimization constraint, movement errors did not vary, whereas the movement time decreased. With the time-matching constraint, the errors decreased as a session proceeded. These results were discussed in terms of the combination of signal-dependent noises and exploratory search noises. It is suggested that updating spatial and temporal factors does not appear to occur simultaneously in motor learning.
