In this paper we propose an anti-inertial motion (AIM) bias that can explain several intuitive physics beliefs including the straight-down belief and beliefs held concerning the pendulum problem. We show how the AIM bias also explains two new beliefs that we explore – a straight-up-and-down belief as well as a straight-out/backward bias that occurs for objects traveling in one plane that are then thrown in another plane, ostensibly affording a greater opportunity for perception of canonical motion. We then show how the AIM bias in general is invariant across perceived/imagined speed of the object carrier, only altering percentages of straight-out from backward responses, and why occluding the carrier once the object is released into a second plane does not result in more veridical perception. The AIM bias serves as a simple explanation for a family of beliefs including those in the current paper as well as those shown in previous work.

在本文中，我们提出了一种反惯性运动 (AIM) 偏差，它可以解释几种直观的物理信念，包括直下信念和关于钟摆问题的信念。我们展示了 AIM 偏差如何也解释了我们探索的两个新信念——一个直接向上和向下的信念以及一个直接/向后偏差，发生在一个平面上的物体，然后被扔到另一个平面上，表面上为感知规范运动提供了更大的机会。然后，我们展示了 AIM 偏差通常如何在物体载体的感知/想象速度上保持不变，仅改变后向响应的直出百分比，以及为什么一旦物体被释放到第二个平面就遮挡载体不会导致更真实的感知。
