People remember moving objects as having moved farther along in their path of motion than is actually the case; this is known as representational momentum (RM). Some authors have argued that RM is an internalization of environmental properties such as physical momentum and gravity. Five experiments demonstrated that a similar memory bias could not have been learned from the environment. For right-handed S, objects apparently moving to the right engendered a larger memory bias in the direction of motion than did those moving to the left. This effect, clearly not derived from real-world lateral asymmetries, was relatively insensitive to changes in apparent velocity and the type of object used, and it may be confined to objects in the left half of visual space. The left-right effect may be an intrinsic property of the visual operating system, which may in turn have affected certain cultural conventions of left and right in art and other domains.
人们记得移动的物体在其运动路径上移动的距离比实际情况更远；这被称为表征动量（RM）。一些作者认为，RM是诸如物理动量和重力等环境属性的内化。五个实验表明，类似的记忆偏差不可能从环境中学到。对于右利手的受试者，明显向右移动的物体在运动方向上产生的记忆偏差比向左移动的物体更大。这种效应显然并非源于现实世界中的横向不对称，它对表观速度和所用物体类型的变化相对不敏感，并且可能仅限于视觉空间左半部分的物体。左右效应可能是视觉操作系统的一种内在属性，这反过来可能影响了艺术和其他领域中关于左右的某些文化习俗。
