大脑同时接受来自多种感觉方式的输入，但我们对外部世界的体验是一个单一的综合感受。这种整合过程必须克服感知信息在感觉模态之间发生冲突的情况。在这种冲突下，来自每种模态的信息的相对权重通常取决于给定的任务。对于视觉和触觉模态之间的冲突，视觉信息已被证明会影响触觉判断的对象身份，空间特征（如位置，大小），纹理和重量。在这里，我们测试了一个新的实例的触觉视觉冲突的感知扭矩。我们要求参与者持有左右不平衡的物体，同时观看该物体的可能左右镜像反转的图像。尽管直觉，更近的触觉信息应该占主导地位的扭矩感知，我们发现，视觉信息施加扭矩感知的重大影响，即使当参与者知道视觉信息是不可靠的。
The brain receives input from multiple sensory modalities simultaneously, yet we experience the outside world as a single integrated percept. This integration process must overcome instances where perceptual information conflicts across sensory modalities. Under such conflicts, the relative weighting of information from each modality typically depends on the given task. For conflicts between visual and haptic modalities, visual information has been shown to influence haptic judgments of object identity, spatial features (eg location, size), texture, and heaviness. Here we test a novel instance of haptic–visual conflict in the perception of torque. We asked participants to hold a left–right unbalanced object while viewing a potentially left-right mirror-reversed image of the object. Despite the intuition that the more proximal haptic information should dominate the perception of torque, we find that visual information exerts substantial influences on torque perception even when participants know that visual information is unreliable.
