Two groups of 20 Ss each run individually in a soundproff chamber heated to 115 F and humidified to 100%. Ss in the experimental group received brief presentation of cool air contingent upon wmitted GSRs during 20 min of acquisition. Control Ss were matched on at a time in operant rate and were yoked one at a time to receive the cool air on a response-independent schedule. Both groups increased significantly in rate of unelicited GSRs during acquisition, with the experimental Ss' curve rising more rapidly and both groups attaining equivalent terminal levels. During extinction, the groups maintained high levels of responding and did not differ. Examination of basal skin conductance data ruled our an activation hypothesis. In the control Ss, terminal response frequency was significantly correlated with percentage of fortuitous response-contigent reinforcement. It was concluded that both croups were conditioned, with the controls receiving intermittent reinforcement sufficiently often to elevate their responding. The cool air was judged to be an effective reinforcer of unelicited GSRs, perhaps more effective than those used in previous studies.
两组，每组20名被试，分别在一个加热到115华氏度且湿度达到100%的隔音室内单独进行实验。实验组的被试在20分钟的习得期内，每当出现自主皮肤电反应（GSR）时，会短暂地接触冷空气。对照组的被试在操作反应率上与实验组被试进行匹配，并且每次将一名对照组被试与实验组被试配对，使对照组被试按照与反应无关的时间表接受冷空气。在习得期内，两组被试的非诱发GSR率均显著增加，实验组被试的曲线上升得更快，且两组最终达到了相同的水平。在消退期，两组被试都保持了较高的反应水平，且没有差异。对基础皮肤电导率数据的检查排除了激活假说。在对照组被试中，最终反应频率与偶然的反应相关强化的百分比显著相关。得出的结论是，两组都形成了条件反射，对照组被试足够频繁地接受间歇性强化，从而提高了他们的反应。冷空气被判定为非诱发GSR的有效强化物，可能比之前研究中使用的强化物更有效。
