“内感受觉知”，定义为个体对内部身体信号的觉知，在多感觉整合的条件下调节自我/他人的区分。我们在这里研究，第一次，在运动领域的自我/他人区分的内感受性意识的潜在影响。在自动模仿中，模仿抑制是一个人成功区分内部产生的运动表征和观察他人动作触发的运动表征的指标。这是衡量的“一致性效应”，这是平均反应时间之间的差异时，观察到的行动是“不一致”与所需的行动，当它是“一致”。本研究比较了典型的手指抬起范式中的一致性效应，以心跳知觉测量的内感受性意识。与预期相反，内感受性意识与一致性效应呈正相关，这种效应取决于不一致条件下的平均反应时间，表明良好的心跳感知者更难抑制模仿倾向。潜在地，高的内感受性意识涉及对行为后果的更强的内感受性表征，这意味着更高的同理心，对观察到的行为的更大的运动反应，因此更倾向于模仿。我们的研究结果也可以初步解释内感受的预测编码帐户。(C)2014爱思唯尔有限公司版权所有。
'Interoceptive awareness', defined as the individual's awareness of internal body signals, modulates self/other distinction under conditions of multisensory integration. We examined here, for the first time, the potential impact of interoceptive awareness on self/other distinction in the motor domain. In automatic imitation, inhibition of imitation is an index of an individual's success in distinguishing internally generated motor representations from those triggered by observing another person's action. This is measured by the 'congruency effect', which is the difference between mean reaction times when the observed action is 'incongruent' with the required action and when it is 'congruent'. The present study compared the congruency effect in a typical finger lifting paradigm, with interoceptive awareness measured by heartbeat perception. Contrary to expectation, interoceptive awareness was positively correlated with the congruency effect and this effect depended on mean reaction times in the incongruent condition, indicating that good heartbeat perceivers had more difficulty inhibiting the tendency to imitate. Potentially, high interoceptive awareness involves stronger interoceptive representations of the consequences of an action, implying higher empathy, greater motor reactivity in response to observed action and hence a greater tendency to imitate. Our results may also tentatively be explained within a predictive coding account of interoception. (C) 2014 Elsevier Ltd. All rights reserved.
