Perceptual illusions of the distance between two touches have been used to study mental representations of the body since E. H. Weber's classic studies in the nineteenth century. For example, on many body parts tactile distance is anisotropic, with distances aligned with body width being perceived as larger than distances aligned with body length on several skin regions. Recent work has demonstrated sex differences in other distortions of mental body representations, such as proprioceptive hand maps. Given such findings, I analysed the results of 24 experiments, conducted by myself and my colleagues, measuring tactile distance anisotropy on the hand dorsum in both women and men. The results showed clear, and highly consistent anisotropy in both women and men, with no evidence for any sex difference.
自 19 世纪 E. H. 韦伯的经典研究以来，人们一直利用触碰两点之间距离的感知错觉来研究身体的心理表象。例如，在许多身体部位，触觉距离具有各向异性，与身体宽度对齐的距离比在几个皮肤区域与身体长度对齐的距离被感知为更大。最近的研究表明，在心理身体表象的其他扭曲方面存在性别差异，例如本体感受手图。鉴于这些发现，我分析了我自己和同事进行的 24 项实验的结果，这些实验测量了女性和男性手中背的触觉距离各向异性。结果表明，女性和男性都存在明显且高度一致的各向异性，没有任何性别差异的证据。
