We combine a convex facial mask with a concave torso-or vice versa-thus creating a single rigid object with a transition area at the neck, where convexity changes to concavity. This combination creates stunning illusions when the rigid object is set to motion. The two simplest effects are (1) when the object is rotated about its axis, the head appears to twist with respect to the torso, as in "The Exorcist" film; (2) when it is rotated around an axis parallel to the shoulders, the head appears to hinge around the torso. More complex illusory effects result from more complex motions. The involvement of higher-level perceptual processes may account for the illusory effects.
我们将一个凸面的面部面罩与一个凹面的躯干部分相结合——反之亦然——从而创建一个单一的刚性物体，在颈部有一个过渡区域，凸度在此转变为凹度。当这个刚性物体处于运动状态时，这种组合会产生惊人的错觉效果。两种最简单的效果是：（1）当物体绕其轴旋转时，头部相对于躯干似乎在扭转，就像在电影《驱魔人》中那样；（2）当它绕平行于肩膀的轴旋转时，头部似乎在躯干周围转动。更复杂的运动则会产生更复杂的错觉效果。高级感知过程的参与可能是这些错觉效果产生的原因。
