Interoception is essential for the maintenance of physical and mental health. Paradigms assessing cardioceptive accuracy do not separate sensitivity from bias or are very demanding. We present the piloting (study 1; N = 60) and psychometric evaluation and validation (study 2; N = 84) of a novel task for the assessment of cardiac interoceptive perception following the principles of signal detection theory. By disentangling sensitivity and response bias, we demonstrate that the previously used interoceptive accuracy score of the heartbeat mental tracking task represents an amalgam of sensitivity and response bias. The new task demonstrated adequate test-retest reliabilities for sensitivity (d') and response bias (c). Sensitivity was inversely related (β = -.36) to somatic symptom distress after statistically controlling for response bias. The novel cardiovascular signal detection task is easy to implement, feasible, and promising in terms of unraveling the role of (cardiac) interoceptive perception in psychopathology.

心脏互感：一种新颖的信号检测方法以及与躯体症状困扰的关系。

互感对维持身心健康至关重要。评估心脏感受准确度的范例不能将敏感性与偏倚分开，或者要求很高。我们提出了一项新任务的试点（研究1； N = 60）以及心理测量评估和验证（研究2； N = 84），用于遵循信号检测理论的原理来评估心脏感受性知觉。通过解开敏感度和反应偏差，我们证明了心跳心理跟踪任务先前使用的感知准确度评分代表了敏感度和反应偏差的混合物。这项新任务证明了在灵敏度（d'）和响应偏差（c）方面具有足够的重测信度。在统计上控制反应偏倚后，敏感性与躯体症状困扰呈负相关（β= -.36）。就阐明（心脏）感官知觉在心理病理学中的作用而言，新颖的心血管信号检测任务易于实施，可行且很有前途。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。
