A recent analysis of magic tricks suggests the existence of a perceptual illusion where the space hidden behind an occluding object is experienced as empty in a strangely compelling way. Here, we show that this illusion of absence is not just a trivial consequence of the lack of retinal stimulation but rather the result of an active process of perceptual construction. The results of a simple experiment show that this perceptual illusion of absence can in turn trigger perceptual processes which generate an immediate perceptual impression of levitation via a percept-percept coupling. This suggests that magical illusions of levitation are partially driven by an immediate perceptual impression of floating in thin air. The perceptual mechanisms underlying the illusion of absence are hitherto unknown, but our results provide support for a potential explanation based on the generic view principle.
最近对魔术的一项分析表明，存在一种感知错觉，即被遮挡物体后面隐藏的空间会以一种奇怪的令人信服的方式被体验为空的。在这里，我们表明这种缺失错觉不仅仅是视网膜刺激缺乏的微不足道的结果，而是感知构建的一个主动过程的结果。一个简单实验的结果表明，这种缺失的感知错觉反过来可以触发感知过程，通过感知-感知耦合产生立即的悬浮感知印象。这表明悬浮的魔术错觉部分是由在空气中漂浮的直接感知印象驱动的。迄今为止，缺失错觉背后的感知机制尚不清楚，但我们的结果为基于一般视图原则的潜在解释提供了支持。
