Abstract

Humans have a tendency to perceive motion even in static images that simply "imply" movement. This tendency is so strong that our memory for actions depicted in static images is distorted in the direction of implied motion - a phenomenon known as representational momentum (RM). In the present study, we created an RM display depicting a pattern of implied (clockwise) rotation of a rectangle. Young adults viewers' memory of the final position of the test rectangle was biased in the direction of continuing rotation, but older adults did not show a similar memory bias. We discuss several possible explanations for this group difference, but argue that the failure of older adults to shown an RM effect most likely reflects age-related changes in areas of the brain involved in processing real and implied motion.

摘要

人类有一种倾向，即使在仅仅“暗示”运动的静态图像中也能感知运动。这种趋势非常强烈，以至于我们对静态图像中描绘的动作的记忆会朝着暗示运动的方向扭曲——这一现象被称为表象动量（RM）。在本研究中，我们创建了一个 RM 显示器，显示一个矩形的暗示（顺时针）旋转模式。年轻成年人观看者对测试矩形的最终位置的记忆偏向于继续旋转，但老年人则没有表现出类似的记忆偏差。我们讨论了几种可能的解释，但认为老年人没有表现出 RM 效应，最有可能反映了与处理真实和暗示运动相关的大脑区域的年龄相关变化。
