为了检查刺激显著性对胫传导反应（SCR）的影响，21秒。1000 Hz音调在一辆车或另一辆车中响起。在许多音调期间发生咔嗒声，并且光信号总是跟随偏移9秒。研究了四组：一组被告知在听到任何咔嗒声时立即踩下踏板;另一组只在特定耳朵听到音调时才踩下踏板;第三组也只对特定耳朵做出反应，但要等到音调偏移后的灯光才按下踏板;第四组只是听着没有反应。关于刺激显著性对SCR的增量效应的一系列预测中的每一个都在任何试验中提供信息的每个点得到了证实-即，音调开始、咔嗒声、音调偏移、轻开始。这对于两个独立组以及我们的S内（耳间）比较均是如此。言语诱导的“重要性”的存在及其影响的复杂性表明，在“外围”SCR的诱发中存在中央调解。被确定为与运动反应时间相关，不习惯，并没有与其他信号在这项任务中引起的SCR。执行SCR并不简单地反映了“重要性”的判断，相反，它是定性区别于其他SCR，在一般情况下，与刺激的“重要性”。有一些证据表明，一个警报SCR了，但这是不太尖锐的定义。
To examine the influence of stimulus significance on the shin conductance response (SCR) a 21 sec. 1000‐Hz tone was sounded variously In one car or the other. A click occurred during many tones, and a light signal always followed offset by 9 sec. Four groups were studied: one was told In press a pedal immediately on hearing any click; another only on hearing the click during a tone in a specified ear: a third was also to respond only to the specified ear, but was to withhold the press until the light following tone‐offset; a fourth group simply listened without and response. Each of a series of predictions regarding the incremental effect of stimulus significance on the SCR was confirmed, at each point at which information was delivered on any trial ‐ i.e., tone‐onset, click, tone‐offset, light‐onset. This was true for both independent as well us for within‐.S (between ear) comparisons. The presence of verbally‐induced “significance” as well as the complex nature of its influence indicated the presence of central mediation in the elicitation of “peripheral” SCRs. Was identified which correlated uniquel with motor reaction time, did not habituate, and did not correlate with SCRs elicited by other signals in this task. The execute SCRs did not simply reflect judgments of “significance” rather, it was qualitatively distinguished from other SCRs which, in general, were associated with stimulus “significance” There was some evidence of an alerting SCR too, hut this was less sharply defined.
