Normally, haptic perception of the left hand surpasses that of the right. But simultaneously playing music into the left (but not the right) ear reverses this superiority. This suggests that the left cerebral hemisphere has full haptic perceptual capability, which is subject to right hemisphere interference unless the latter's attentional mechanisms are engaged by contralateral peripheral stimulation.
通常情况下，左手的触觉感知能力优于右手。但同时向左耳（而非右耳）播放音乐时，这种优势就会逆转。这表明左脑半球具备完整的触觉感知能力，除非右脑半球的注意力机制被对侧外周刺激激活，否则该能力会受到右脑半球的干扰。
