Visual discrimination and learning of motion trajectories

到目前为止，视觉运动知觉的研究可以细分为物体运动(通常是平移)和生物运动，通常用点光显示器来研究。然而，仍有一个在人类感知和学习中发挥重要作用的运动知觉类别尚未被探索：对闭合运动轨迹的知觉。在流水线上控制一台机器，运动中的许多动作，以及其他熟练的动作，都涉及识别和学习重复的运动模式。对复杂运动轨迹的感知可以被认为与一种以前没有研究过的生物运动有关。在这项建议中，我介绍了一种新的刺激范式，用于研究周期性运动轨迹的辨别、学习和分类。拟议中的实验将利用心理物理学和脑成像(FMRI)来探索这一新领域。

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.
