We have previously found that attention to internal somatic sensations (interoceptive attention) during a heart beat perception task increases the misperception of external touch on a somatic signal detection task (SSDT), during which healthy participants erroneously report feeling near-threshold vibrations presented to their fingertip in the absence of a stimulus. However, it has been suggested that mindful interoceptive attention should result in more accurate somatic perception, due to its non-evaluative and controlled nature. To investigate this possibility, 62 participants completed the SSDT before and after a period of brief body-scan mindfulness meditation training, or a control intervention (listening to a recorded story). The meditation intervention reduced tactile misperception and increased sensitivity during the SSDT. This finding suggests that the perceptual effects of interoceptive attention depend on its particular nature, and raises the possibility that body-scan meditation could reduce the misperception of physical symptoms in individuals with medically unexplained symptoms.
我们之前发现，在心搏感知任务中关注内部躯体感觉（内感受注意）会增加对外在触觉的错误感知，即在躯体信号检测任务（SSDT）中，健康参与者在没有刺激的情况下错误地报告感觉到近阈值振动出现在指尖。然而，有人认为，正念内感受注意应该会导致更准确的躯体感知，因为它是非评价性和控制性的。为了研究这种可能性，62 名参与者在进行短暂的身体扫描正念冥想训练或对照干预（听录音故事）前后完成了 SSDT。冥想干预减少了触觉错觉，并提高了 SSDT 期间的敏感性。这一发现表明，内感受注意的知觉效应取决于其特定的性质，并提出了身体扫描冥想可能减少有医学无法解释症状的个体对身体症状的错觉的可能性。
