心跳计数任务广泛用于评估感知心脏感觉的能力。然而，这项任务的表现可能取决于对心脏刺激的敏感性以外的过程。在执行心跳计数任务之前，通过问卷评估关于姿势和运动挑战对心率影响的信念，然后在计数任务期间通过姿势和运动的变化来操纵实际心率。平均而言，计算出的心率更接近于对心率的信念，而不是实际心率。分层多元回归分析表明，(a) 在控制实际心率的同时，相信心率可以预测计数心率；(b) 在控制心率信念的同时，实际心率也可以预测计数心率。这些数据表明，心跳计数的速率受到对心率的信念和心脏感觉处理的影响。
The heartbeat counting task is used widely to assess the ability to perceive cardiac sensations. However, performance on this task may be determined by processes other than sensitivity to cardiac stimuli. Beliefs about the effects of postural and exercise challenges on heart rate were assessed by questionnaire prior to performing the heartbeat counting task, and then actual heart rate was manipulated during the counting task by changes in posture and exercise. On average, counted heart rates were closer to beliefs about heart rate than to actual heart rate. Hierarchical multiple regression analyses indicated that (a) believed heart rates predicted counted heart rates while controlling for actual heart rates and (b) actual heart rates also predicted counted heart rate while controlling for heart rate beliefs. These data suggest that the rate of heartbeat counting is influenced by beliefs about heart rate and by the processing of cardiac sensations.
