两个实验研究了24个习惯化训练试验与音调或振动触觉刺激后，对皮肤电反应和对二级任务探针刺激的反应时间的影响。探针是持续时间为500 ms的视觉刺激，刺激内探针在刺激开始后300 ms发生。实验1交叉变化与没有变化的训练刺激的方式。实验组的皮肤电反应（SCRs）在测试试验中大于对照组，实验组的测试试验反应大于第一次训练试验。探针反应时间慢的测试试验中的实验组比对照组，和内刺激探针反应时间慢于刺激间隔反应时间早在习惯化系列。实验2交叉的变化与没有变化的存在下，一个次要的任务。无论是否存在次要任务，实验组的测试SCR均大于对照组。此外，在任务和非任务条件下，实验组的测试试验反应大于第一次训练试验。在任务条件下，实验条件下的反应时比控制条件下的反应时慢。此外，在实验条件下的反应时间是缓慢的变化试验期间比在第一次训练刺激。这些数据为习惯化的非比较理论提供了困难，似乎最容易用强调外推过程重要性的习惯化理论来解释。
Two experiments studied the effects of intermodality change on electrodermal responses and on reaction time to a secondary task probe stimulus after 24 habituation training trials with either a tone or a vibrotactile stimulus. The probe was a visual stimulus of 500 ms duration, and within-stimulus probes occurred 300 ms following stimulus onset. Experiment 1 crossed change versus no change with modality of the training stimulus. Skin conductance responses (SCRs) were larger in the experimental group than in the control on the test trial, and in the experimental group, test trial responses were larger than those on the first training trial. Probe reaction time was slower on the test trial in the experimental group than in the control, and within-stimulus probe reaction time was slower than interstimulus interval reaction time early in the habituation series. Experiment 2 crossed change versus no change with the presence of a secondary task. Test trial SCRs were larger in the experimental group than in the control, regardless of whether or not the secondary task was present. In addition, test trial responses in the experimental group were larger than those on the first training trial in both the task and no-task conditions. Within the task condition, reaction time was slower in the experimental condition than in the control on the test trial. In addition, reaction time in the experimental condition was slower during the change trial than during the first training stimulus. The data provide difficulties for noncomparator theories of habituation and seem to be most easily explained by theories of habituation that emphasize the importance of an extrapolatory process.
