Evidence suggests that intelligence is positively associated with performance on the heartbeat counting task (HCT). The HCT is often employed as measure of interoception - the ability to perceive the internal state of one's body - however it's use remains controversial as performance on the HCT is strongly influenced by knowledge of resting heart rate. This raises the possibility that heart rate knowledge may mediate the previously-observed association between intelligence and HCT performance. Study One demonstrates an association between intelligence and HCT performance (N = 94), and Study Two demonstrates that this relationship is mediated by knowledge of the average resting heart rate (N = 134). These data underscore the need to account for the influence of prior knowledge and beliefs when examining individual differences in cardiac interoceptive accuracy using the HCT.
有证据表明，智力与心跳计数任务（HCT）的表现呈正相关。HCT常被用作内感受（感知自身身体内部状态的能力）的一种测量方法，然而，由于HCT的表现受到静息心率知识的强烈影响，其用途仍存在争议。这就增加了心率知识可能介导先前观察到的智力与HCT表现之间关联的可能性。研究一证明了智力与HCT表现之间存在关联（N = 94），研究二表明这种关系是由平均静息心率的知识介导的（N = 134）。这些数据强调，在使用HCT检查心脏内感受准确性的个体差异时，需要考虑先验知识和信念的影响。
