对物体重量的感知与其形状和运动有关。研究表明，在被动观察过程中，在水平和垂直环境中，受试者的体重知觉和运动之间的关系普遍相同。在这里，我们展示了一个矛盾的发现，因为并不是所有的人类都有相同的运动-重量配对。在一个虚拟环境中，参与者控制斜坡的陡度，以调查滑动运动与重量知觉之间的关系。我们的发现表明，尽管主观，但感知中的运动-重量关系可以在坡度环境中识别出来。当引入控制运动的环境参数的变化，特别是倾斜度和表面质地时，就会发现这些个人主义的感觉。环境参数的差异，再加上个人因素，如经验，影响了参与者的体重感知。这种现象可能提供证据，证明中枢神经系统有能力根据来自感觉系统的信息选择和组合内部模型。这些结果还表明，通过呈现强烈的感觉线索来操纵管理内部模型的机制，有可能控制人类的感知。
Perception of an object’s weight is linked to its form and motion. Studies have shown the relationship between weight perception and motion in horizontal and vertical environments to be universally identical across subjects during passive observation. Here we show a contradicting finding in that not all humans share the same motion-weight pairing. A virtual environment where participants control the steepness of a slope was used to investigate the relationship between sliding motion and weight perception. Our findings showed that distinct, albeit subjective, motion-weight relationships in perception could be identified for slope environments. These individualistic perceptions were found when changes in environmental parameters governing motion were introduced, specifically inclination and surface texture. Differences in environmental parameters, combined with individual factors such as experience, affected participants’ weight perception. This phenomenon may offer evidence of the central nervous system’s ability to choose and combine internal models based on information from the sensory system. The results also point toward the possibility of controlling human perception by presenting strong sensory cues to manipulate the mechanisms managing internal models.
