The purpose of this research is to present the employment of a simple-to-use crossmodal method for measuring haptic size illusions. The method, that we call See what you feel, was tested by employing Uznadze’s classic haptic aftereffect in which two spheres physically identical (test spheres) appear different in size after that the hands holding them underwent an adaptation session with other two spheres (adapting spheres), one bigger and the other smaller than the two test spheres. To measure the entity of the illusion, a three-dimensional visual scale was created and participants were asked to find on it the spheres that corresponded in size to the spheres they were holding in their hands out of sight. The method, tested on 160 right-handed participants, is robust and easily understood by participants.

看看你的感受：用于测量触觉尺寸错觉的跨模态工具。


本研究的目的是提出使用一种简单易用的跨模态方法来测量触觉尺寸错觉。我们称之为“查看你的感受”的方法是通过采用 Uznadze 的经典触觉后效应进行测试的，其中两个物理上相同的球体（测试球体）在握着它们的手与其他两个球体（适应球体）进行适应过程后看起来大小不同。 ），一个比两个测试球大，另一个比两个测试球小。为了测量幻觉的实体，创建了一个三维视觉尺度，并要求参与者在其上找到与他们手中握在视线之外的球体大小相对应的球体。该方法经过 160 名惯用右手的参与者的测试，非常稳健且易于参与者理解。
