背景内感受是对来自身体任何部位的传入信息的感知。内感受的个体差异与情感加工和决策加工有关。躯体标记假说总结了内感受对决策过程的潜在影响。根据这一理论，内感受性功能障碍的个体表现出不利的决策。最近，增强内感受的准确性，内感受的客观决策任务评估的一个元素，已被证明使用生物反馈。Garfinkle等人开发了一种内感受训练任务，该任务是从心跳感知任务修改而来的，其增强了内感受的准确性并减少了焦虑症状。本研究旨在探讨内感受训练对决策过程的影响。基于内感受准确性的提高，我们假设决策得分会以一种表明理性增加的方式变化。方法采用内感受性训练进行纵向干预研究。干预前后分别采用心跳感知任务和理性决策任务评估决策过程的内感受准确性和合理性。14名健康志愿者（9名女性;平均年龄21.9 ± 4.5岁）参加了研究。该分析包括来自12名参与者的数据。为探讨内感受准确性对决策合理性影响的个体差异，对内感受准确性指标与决策合理性指标的变化率进行相关分析。结果内感受性训练显著提高了内感受性准确性得分，降低了躯体症状和状态焦虑得分。相比之下，内感受性训练并没有引起决策指数的显着变化。内感受准确性指标的变化率与决策的合理性呈显著正相关。结论内感受与决策合理性之间存在因果关系。这些发现将通过关注内感受来增强对与心理治疗相关的决策改变的潜在机制的理解。
Background Interoception is the perception of afferent information that arises from any point within the body. Individual differences in interoception have been associated with affective processing and decision-making processing. The somatic marker hypothesis summarizes the potential effects of interoception on decision-making processes. According to this theory, individuals with interoceptive dysfunction exhibit disadvantageous decision making. Recently, enhancement of interoceptive accuracy, an element of interoception assessed by objective decision-making tasks, has been demonstrated using biofeedback. Garfinkle et al. developed an interoceptive training task, modified from the heartbeat perception task, which enhanced interoceptive accuracy and reduced anxiety symptoms. The purpose of this study was to determine the effects of interoceptive training on decision-making processes. Based on improvements in interoceptive accuracy, we hypothesized that decision-making scores would change in a manner indicative of increased rationality. Methods This longitudinal interventional study was performed with interoceptive training. Before and after the intervention, interoceptive accuracy and rationality of decision-making processes were assessed using a heartbeat perception task and rational decision-making tasks, respectively. Fourteen healthy volunteers (nine women; mean age, 21.9 +/- 4.5 years) participated. The analysis included data from 12 participants. To detect individual differences in the effects of interoceptive accuracy on rationality of decision making, correlation analysis was conducted on change ratios of the indices of interoceptive accuracy and rationality of decision making. Results Interoceptive training resulted in significant enhancement of interoceptive accuracy scores and significant reductions in somatic symptom and state anxiety scores. In contrast, interoceptive training did not cause significant changes in decision-making indices. There was a significant positive correlation between change ratios of indices of interoceptive accuracy and rationality of decision making. Conclusions The results suggested a causal relation between interoception and rationality of decision making. These findings will enhance the understanding of mechanisms underlying alterations of decision-making related to psychotherapy by focusing on interoception.
