抽象的。健康的人在水平面上进行手臂运动,从初始位置朝向记忆中的目标,而运动和目标被投影在垂直的计算机显示器上。我们分析了运动终点的平均误差,并观察到两种不同的系统误差模式。第一种模式导致运动端点向包含所有目标位置的假想圆形区域的四个象限的对角线聚集(倾斜效应)。第二种模式导致运动终点倾向于更靠近身体或等效地低于计算机显示器上的实际目标位置(y效应)。这两种模式的系统误差的幅度增加时,施加的时间延迟之间的目标介绍和启动的运动。此外,在一些目标附近的稳定的视觉提示的存在下,施加了一种新的模式的系统误差,包括最小的错误附近的线索和线索象限内的其他运动端点的倾向,错误远离线索的位置。类似于斜效应的系统性错误模式已经在文献中报道,并归因于主题的空间概念分类。鉴于本工作中的错误的属性,我们讨论了这种概念效应可能反映在各种各样的视觉任务的可能性。我们的研究结果还提供了深入了解的问题,在执行这些瞄准运动中使用的参考帧。因此,倾斜效果可以反映以手为中心的参考系,而y效果可以反映以身体或眼睛为中心的参考系。稳定的视觉线索的存在可能会强加一个额外的线索为中心(allocentric)的参考框架。
Abstract. Healthy humans performed arm movements in a horizontal plane, from an initial position toward remembered targets, while the movement and the targets were projected on a vertical computer monitor. We analyzed the mean error of movement endpoints and we observed two distinct systematic error patterns. The first pattern resulted in the clustering of movement endpoints toward the diagonals of the four quadrants of an imaginary circular area encompassing all target locations (oblique effect). The second pattern resulted in a tendency of movement endpoints to be closer to the body or equivalently lower than the actual target positions on the computer monitor (y-effect). Both these patterns of systematic error increased in magnitude when a time delay was imposed between target presentation and initiation of movement. In addition, the presence of a stable visual cue in the vicinity of some targets imposed a novel pattern of systematic errors, including minimal errors near the cue and a tendency for other movement endpoints within the cue quadrant to err away from the cue location. A pattern of systematic errors similar to the oblique effect has already been reported in the literature and is attributed to the subject's conceptual categorization of space. Given the properties of the errors in the present work, we discuss the possibility that such conceptual effects could be reflected in a broad variety of visuomotor tasks. Our results also provide insight into the problem of reference frames used in the execution of these aiming movements. Thus, the oblique effect could reflect a hand-centered reference frame while the y-effect could reflect a body or eye-centered reference frame. The presence of the stable visual cue may impose an additional cue-centered (allocentric) reference frame.
