情绪和情感感受通过内感受受到身体唤醒的内部状态的影响。自闭症谱系障碍（ASC）与识别他人情绪和调节自己情绪的困难有关。我们测试的假设，在人与ASC，这种情感的差异可能会出现异常的内感受性处理。我们证明，ASC患者的内感受准确性降低（使用心跳检测测试进行量化），内感受敏感性（自我报告问卷中对内部感觉的主观敏感性）夸大，反映了客观检测身体信号的能力受损以及过度膨胀的身体感觉主观感知。这两个内感受轴的差异可以计算为特质预测误差。这种错误与情感敏感性和焦虑症状的发生有关。我们的研究结果表明，ASC中情绪缺陷和情感症状的起源在于身心之间的界面，特别是在内感受信息的期望驱动的解释中。(C)2015爱思唯尔B.V.保留所有权利。
Emotions and affective feelings are influenced by one's internal state of bodily arousal via interoception. Autism Spectrum Conditions (ASC) are associated with difficulties in recognising others' emotions, and in regulating own emotions. We tested the hypothesis that, in people with ASC, such affective differences may arise from abnormalities in interoceptive processing. We demonstrated that individuals with ASC have reduced interoceptive accuracy (quantified using heartbeat detection tests) and exaggerated interoceptive sensibility (subjective sensitivity to internal sensations on self-report questionnaires), reflecting an impaired ability to objectively detect bodily signals alongside an over-inflated subjective perception of bodily sensations. The divergence of these two interoceptive axes can be computed as a trait prediction error. This error correlated with deficits in emotion sensitivity and occurrence of anxiety symptoms. Our results indicate an origin of emotion deficits and affective symptoms in ASC at the interface between body and mind, specifically in expectancy-driven interpretation of interoceptive information.
