Abstract

Different individuals learn different solutions to the same perceptual-motor task regardless of the fact that they may undergo the same practice conditions. In the current study, we characterized individual solutions to a perceptual-motor task. Eighteen self-declared right-handed participants were requested to intercept a moving target controlling a virtual ball using a computer mouse. Target speed varied across trials. Participants visited the lab 2 days in a row. They practiced 250 trials on Day 1 and 50 trials on Day 2. We assessed participants’ preferred speed and maximum speed on both days. We combined a qualitative description of solutions on the task space and the quantitative growth curve analysis to address individual differences. Results indicated an overall trend to increase the ball release speed to handle the task constraints. Moreover, the local shape of the solution manifold constrained individuals’ solutions. Contrary to our expectations, neither individual preferred speed nor individual maximum speed improved model fit.

运动学习的个体解决方案:结合不同的分析
不同的人对相同的感知运动任务学习不同的解决方案,而不管他们可能经历相同的练习条件。在当前的研究中,我们描述了知觉运动任务的个体解决方案。18名自称为右撇子的参与者被要求用电脑鼠标控制一个虚拟球,拦截一个移动的目标。不同试验的目标速度不同。参与者连续2天参观实验室。他们在第一天练习了250次,第二天练习了50次。我们评估了参与者在这两天的首选速度和最大速度。我们结合了任务空间上解决方案的定性描述和定量增长曲线分析来解决个体差异。结果表明,总体趋势是提高球释放速度来处理任务约束。此外,解流形的局部形状约束了个体的解。与我们的预期相反,个人首选速度和个人最大速度都没有改善模型拟合。

期刊介绍: The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
