In Exp. 1 subjects, classified on the basis of locus of control scores, performed both reaction time and mental arithmetic tasks. In Exp. 2, similarly classified subjects were required to estimate the duration of a signal with feedback following each trial. Between-groups comparisons in Exp. 1 showed no differences on heart rate or performance measures. This does not support an explanation of differential heart rates during cardiac conditioning based upon cognitive styles of "rejecting" or "accepting" stimuli. Similar comparisons in Exp. 2 indicated significant differences for heart rate and proficiency in time estimation. These differences suggest greater task involvement for internally controlled subjects on feedback tasks, with cardiac acceleration a function of that involvement.
在实验1中，根据控制源分数分类的受试者进行了反应时间和心算任务。在实验2中，对类似分类的受试者要求在每次试验后根据反馈估计信号的持续时间。实验1中的组间比较显示，心率或表现指标没有差异。这并不支持基于“拒绝”或“接受”刺激的认知方式来解释心脏条件反射期间的心率差异。实验2中的类似比较表明，心率和时间估计能力存在显著差异。这些差异表明，内控型受试者在反馈任务上的任务参与度更高，心脏加速是这种参与度的一个函数。
