The enhancement of body awareness is proposed as one of the cognitive mechanisms that characterize mindfulness. To date, this hypothesis is supported by self-report and behavioral measures but still lacks physiological evidence. The current study investigated relation between trait mindfulness (i.e., individual differences in the ability to be mindful in daily life) and body awareness in combining a self-report measure (Multidimensional Assessment of Interoceptive Awareness [MAIA] questionnaire) with analysis of the heartbeat evoked potential (HEP), which is an event-related potential reflecting the cortical processing of the heartbeat. The HEP data were collected from 17 healthy participants under five minutes of resting-state condition. In addition, each participant completed the Freiburg Mindfulness Inventory and the MAIA questionnaire. Taking account of the important variability of HEP effects, analyses were replicated with the same participants three times (in three distinct sessions). First, group-level analyses showed that HEP amplitude and trait mindfulness do not correlate. Secondly, we observed that HEP amplitude could positively correlate with self-reported body awareness; however, this association was unreliable over time. Interestingly, we found that HEP measure shows very poor reliability over time at the individual level, potentially explaining the lack of reliable association between HEP and psychological traits. Lastly, a reliable positive correlation was found between self-reported trait mindfulness and body awareness. Taken together, these findings provide preliminary evidence that the HEP might not support the increased subjective body awareness in trait mindfulness, thus suggesting that perhaps objective and subjective measures of body awareness could be independent.

心跳诱发电位不支持特质正念中强烈的内感受性
身体意识的增强被认为是正念的认知机制之一。迄今为止,这一假设得到了自我报告和行为测量的支持,但仍缺乏生理证据。目前的研究调查了特质正念(即日常生活中正念能力的个体差异)与身体意识之间的关系,结合自我报告测量(多维感知意识评估 [MAIA] 问卷)与对诱发的心跳分析电位(HEP),它是反映心跳皮层处理的事件相关电位。HEP 数据是从 17 名健康参与者在五分钟的静息状态下收集的。此外,每位参与者都完成了弗莱堡正念问卷和 MAIA 问卷。考虑到 HEP 效应的重要可变性,对同一参与者重复分析三次(在三个不同的会话中)。首先,群体层面的分析表明,HEP 幅度和特质正念不相关。其次,我们观察到 HEP 幅度与自我报告的身体意识呈正相关;然而,随着时间的推移,这种关联是不可靠的。有趣的是,我们发现随着时间的推移,HEP 测量在个人层面显示出非常差的可靠性,这可能解释了 HEP 与心理特征之间缺乏可靠关联的原因。最后,在自我报告的特质正念和身体意识之间发现了可靠的正相关关系。综合起来,
