建议采用一种方法来抵消皮肤电导响应性的个体差异。所建议的方法是个体内部反应的标准化。将该方法与极差校正变换进行比较。该比较基于两项实验的数据，这两项实验评估了信息检测任务中对相关刺激和中性刺激的皮肤电反应之间的差异。在第一个实验中，范围校正变换使用主体对信息检测任务中呈现的常规刺激之一引起的最大皮肤电导响应。第二个实验包括对不愉快音调的反应，范围校正变换定义为受试者对给定刺激引起的皮肤电导反应除以对不愉快刺激的反应。对从 2 个实验收集的 5 个数据集进行引导分析，以统计比较转换。在所有情况下，标准分数比范围校正分数更好地区分相关刺激和中性刺激。标准化的优势在第二个实验中更为明显，其中只有标准分数才能在强实验条件和弱实验条件之间产生统计上的显着差异。分析表明，标准评分法的优点主要与其对人的依赖有关，这是比最大反应更稳定、更可靠的统计数据。
A method is suggested to neutralize individual differences in skin conductance responsivity. The method suggested is a standardization of the responses within individuals. This method was compared to the range correction transformation. The comparison was based on data from 2 experiments which evaluated differences between electrodermal responses to relevant and neutral stimuli in information detection tasks. In the 1st experiment the range correction transformation used the maximal skin conductance response evoked by the subject to one of the regular stimuli presented in the information detection task. The 2nd experiment included responses to unpleasant tones and the range correction transformation was defined as the skin conductance response evoked by the subject to a given stimulus, divided by the response to the unpleasant stimulus. A bootstrap analysis was carried out on 5 data sets gathered from the 2 experiments, to statistically compare the transformations. In all cases standard scores better discriminated relevant and neutral stimuli, than range corrected scores. The advantage of standardization was much more salient in the 2nd experiment, where only standard scores produced a statistically significant difference between strong and weak experimental conditions. The analysis demonstrated that the advantage of the method of standard scores is related mainly to its reliance upon the man, which is a more stable and reliable statistic than the maximal response.
