这项实验测试了变力心血管对压力的反应与心跳辨别任务的表现有关的假设。该实验还比较了两种流行的心跳辨别范式--怀特黑德心跳辨别范式和凯特金心跳辨别范式的具体修改的有效性。受试者是48名男性本科生，他们完成了这两种辨别任务，然后接受了心算压力。结果表明，高的心血管反应物比低的反应物是更好的检测手段。结果还表明，受试者在修改的怀特黑德任务上的表现比在修改的Katkin任务上的好。
This experiment tested the hypothesis that inotropic cardiovascular reactivity to stress is related to performance on heartbeat discrimination tasks. The experiment also compared the efficacy of a specific modification of two popular heartbeat discrimination paradigms, Whitehead's and Katkin's. Subjects were 48 male undergraduates who performed both discrimination tasks and then were subjected to mental arithmetic stress. Results indicated that high cardiovascular reactors were better detectors than low reactors. Results also indicated that subjects performed better on the modified Whitehead task than on the modified Katkin task.
