当视觉图案以连续不同的取向显示时，使得旋转或平移被暗示，观察者对最终位置的记忆被向前移位。这种表象动量现象与物理动量有某些相似之处。例如，记忆移位的量与诱导显示的隐含速度成比例;表征动量与最终速度而不是平均速度成比例;表征动量在保持间隔的前250 ms左右遵循连续停止函数。在之前的论文（Kelly & Freyd，1987）中，我们使用音高的隐含变化证明了前向记忆的不对称性，对于没有接受过正式音乐训练的受试者。在这篇论文中，我们重复了我们之前的发现，并表明前向记忆不对称也发生在接受过正规音乐训练的受试者身上（实验1）。然后，我们展示了结构相似性之间的代表性动量在内存中的音高与以前的报告的参数效应，使用视觉刺激。我们报告了听觉动量的速度效应（实验2），我们具体证明了速度效应取决于隐含的加速度（实验3），我们表明听觉动量的停止函数与视觉动量的停止函数定性相同（实验4）。我们认为这些结果的心理表征理论的影响。
When a visual pattern is displayed at successively different orientations such that a rotation or translation is implied, an observer's memory for the final position is displaced forward. This phenomenon of representational momentum shares some similarities with physical momentum. For instance, the amount of memory shift is proportional to the implied velocity of the inducing display; representational momentum is specifically proportional to the final, not the average, velocity; representational momentum follows a continuous stopping function for the first 250 ms or so of the retention interval. In a previous paper (Kelly & Freyd, 1987) we demonstrated a forward memory asymmetry using implied changes in pitch, for subjects without formal musical training. In the current paper we replicate our earlier finding and show that the forward memory asymmetry occurs for subjects with formal musical training as well (Experiment 1). We then show the structural similarity between representational momentum in memory for pitch with previous reports of parametric effects using visual stimuli. We report a velocity effect for auditory momentum (Experiment 2), we demonstrate specifically that the velocity effect depends on the implied acceleration (Experiment 3), and we show that the stopping function for auditory momentum is qualitatively the same as that for visual momentum (Experiment 4). We consider the implications of these results for theories of mental representation.
