在判断短暂的视觉和听觉刺激的一致性的实践后，32名受试者进行了检查的心跳歧视程序，其中音调在0，100，200，300，400，或500毫秒的间隔后，每个R波。在两个阶段的60次试验中，受试者可以根据自己的意愿频繁地检查这些间隔中出现的音调，并且检查的时间也可以很长，然后才能决定哪个间隔产生的刺激与心跳感觉一致。作为一个整体，该组判断R波后200-300 ms的音调与心跳感觉最接近。虽然一些受试者表现出对100-ms和400-ms间期的模态偏好，但没有人偏好0-ms或500-ms间期。在每项试验期间，受试者检查首选间期的频率和时间均高于非首选间期。虽然间隔偏好往往是稳定的两个会议期间，偏好在第二届会议比第一届会议期间的变化较小。此外，从第1阶段到第2阶段，检查的间期数量和每次间期检查的持续时间显著减少，表明心跳一致音识别标准的发展。
After practice in judging the simultaneity of brief visual and auditory stimuli, 32 subjects were examined on a heartbeat discrimination procedure in which tones were presented at intervals of 0, 100, 200, 300, 400, or 500 ms following each R-wave. On each of 60 trials spread over two sessions, tones presented at these intervals could be inspected as frequently and for as long as subjects wished before reaching a decision on which interval yielded stimuli that were coincident with heartbeat sensations. The group as a whole judged tones that were 200-300 ms after the R-wave to be most contiguous with heartbeat sensations. Although some subjects showed modal preferences for the 100-ms and 400-ms intervals, none preferred the 0-ms or 500-ms intervals. During each trial subjects inspected preferred intervals more frequently and for longer than non-preferred intervals. Although interval preferences tended to be stable over the two sessions, preferences were less variable during the second session than during the first session. Furthermore, the number of intervals examined and the duration of each interval examination decreased significantly from Session 1 to Session 2 indicating the development of recognition criteria for heartbeat-coincident tones.
