The experiments reported were designed to examine how the interaction of task and organismic constraints influences the effectiveness of augmented information on the acquisition of a given force-time trace in a finger press isometric task. Experiment 1 showed that kinetic information feedback facilitated acquisition of the gaussian force-time task criterion but that the superimposition of the task criterion information on the augmented information feedback did not further improve performance. Experiment 2 revealed that the addition of task criterion information to the kinetic information feedback was beneficial to performance when the force-time curve was unfamiliar and asymmetrical in shape. Collectively, the findings suggest that the interaction of task and organismic constraints dictates the degree to which both kinetic information feedback and criterion information facilitate the acquisition of skill in isometric tasks.
所报告的实验旨在研究任务和机体限制因素的相互作用如何影响增强信息在手指按压等长任务中获取给定力-时轨迹的有效性。实验1表明，动力学信息反馈有助于获取高斯力-时任务标准，但将任务标准信息叠加在增强信息反馈上并不能进一步提高表现。实验2表明，当力-时曲线形状不熟悉且不对称时，在动力学信息反馈中添加任务标准信息对表现有益。总体而言，研究结果表明，任务和机体限制因素的相互作用决定了动力学信息反馈和标准信息在促进等长任务技能获取方面的程度。
