对运动目标的最终位置的记忆常常从该目标的真实最终位置偏移或移位。早期对这种记忆转移的研究集中在目标的动量和目标表征的动量之间的相似之处，并将这种位移称为表征动量，但除了动量之外，还有许多因素导致了记忆转移。对表征动量和相关位移类型的实证文献的考虑表明，至少有四种不同类型的因素影响这种记忆位移的方向和大小：刺激特征（如目标方向、目标速度）、隐含动力和环境不变量（如隐含动量、重力、摩擦力、向心力）、目标和非目标情境的记忆平均（如对先前目标位置或非目标情境的偏见），以及观察者对未来目标运动和目标/情境相互作用的期望（包括隐性和有意识的）。还考虑了一些旨在解释表征动量和相关位移类型的理论。
Memory for the final position of a moving target is often shifted or displaced from the true final position of that target. Early studies of this memory shift focused on parallels between the momentum of the target and the momentum of the representation of the target and called this displacement representational momentum, but many factors other than momentum contribute to the memory shift. A consideration of the empirical literature on representational momentum and related types of displacement suggests there are at least four different types of factors influencing the direction and magnitude of such memory shifts: stimulus characteristics (e.g., target direction, target velocity), implied dynamics and environmental invariants (e.g., implied momentum, gravity, friction, centripetal force), memory averaging of target and nontarget context (e.g., biases toward previous target locations or nontarget context), and observers' expectations (both tacit and conscious) regarding future target motion and target/context interactions. Several theories purporting to account for representational momentum and related types of displacement are also considered.
