本研究旨在更好地了解目标导向运动的学习过程。受试者在虚拟现实环境中的跑步机上行走，并被要求穿过成对的摆动门。在学习过程开始时（前测），350次试验（中间测试）和700次试验（后测）后，检查受试者的行为。在三个不同的层面上分析了数据，每个层面代表了全球响应的一个特定方面：性能结果、位移运动学和当前到达条件。虽然性能结果的某些方面表明，在中间测试中存在天花板效应，但位移运动学和电流到达条件都清楚地强调了所涉及的控制机制的连续变换。学习过程最好描述为（1）建立特定信息和运动参数之间的关系，以及（2）优化该关系。优化过程的特点是进一步探索现有的行为剧目和信息和运动之间的对话的完善。
This study was designed to better understand the process underlying the learning of goal-directed locomotion. Subjects walked on a treadmill in a virtual reality setting and were asked to cross pairs of oscillating doors. The subjects behaviour was examined at the beginning of the learning process (pretest), after 350 trials (intermediate test), and after 700 trials (posttest). The data were analysed at three different levels, each representing a specific aspect of the global response: performance outcome, displacement kinematics, and current arrival condition. While some aspects of performance outcome suggested the presence of a ceiling effect in the intermediate test, both displacement kinematics and current arrival condition clearly highlighted continuous transformations of the control mechanism involved. The learning process is best described as (1) the establishing of a relationship between specific information and a movement parameter and (2) the optimization of this relationship. The optimization process is characterized by the further exploration of the available behavioural repertoire and by the refinement of the dialogue between information and movement.
