Certain blind individuals have learned to interpret the echoes of self-generated sounds to perceive the structure of objects in their environment. The current work examined how far the influence of this unique form of sensory substitution extends by testing whether echolocation-induced representations of object size could influence weight perception. A small group of echolocation experts made tongue clicks or finger snaps toward cubes of varying sizes and weights before lifting them. These echolocators experienced a robust size-weight illusion. This experiment provides the first demonstration of a sensory substitution technique whereby the substituted sense influences the conscious perception through an intact sense.
某些盲人已经学会解读自身发出声音的回声，以感知周围环境中物体的结构。当前的研究通过测试回声定位引起的物体大小表征是否会影响重量感知，来探究这种独特的感官替代形式的影响范围有多广。一小群回声定位专家在拿起不同大小和重量的立方体之前，会对着它们发出舌头咔哒声或手指 snapping 声。这些回声定位者体验到了强烈的大小-重量错觉。该实验首次证明了一种感官替代技术，即被替代的感官通过一种完好的感官影响有意识的感知。
