Visual discrimination and learning of motion trajectories

迄今为止，对视觉运动感知的研究可以细分为物体运动（通常是平移）和生物运动，通常使用点光显示进行研究。然而，在人类感知和学习中仍有一个未开发的运动感知类别：封闭运动轨迹的感知。在装配线上控制一台机器，在体育运动中的许多动作，以及其他技术动作都涉及到识别和学习重复的动作模式。复杂运动轨迹的感知可能被认为与一种以前没有研究过的生物运动有关。在这个建议中，我介绍了一个新的刺激范式来研究周期运动轨迹的区分、学习和分类。拟议的实验将利用心理物理学和脑成像（fMRI）来探索这个新领域。

Research on visual motion perception to date may be subdivided into object motion (usually translation) and biological motion, generally studied with point-light displays. However, there remains an unexplored category of motion perception that plays an important role in human perception and learning: perception of closed motion trajectories. Controlling a machine on an assembly line, many movements in sports, and other skilled actions all involve recognizing and learning repetitive patterns of movement. Perception of complex motion trajectories may be regarded as related to biological motion of a type not previously studied. In this proposal I introduce a novel stimulus paradigm for studying discrimination, learning, and categorization of periodic motion trajectories. Proposed experiments will utilize psychophysics and brain imaging (fMRI) to explore this new area.
