两种开发的基于模型的阶段性皮肤电导反应分析方法的比较。使用四个数据集来比较预测有效性。 SCRalyze 在 5 次比较中的 4 次中显示出比 Ledalab 更高的预测有效性，并且在第五次比较中显示出相同的预测有效性。在所有比较中，SCRalyze 都显示出比峰值评分更高的预测有效性。如之前的工作所示，基于模型的皮肤电导反应 (SCR) 分析可以提供比操作峰值评分方法噪声更少的交感神经唤醒 (SA) 估计。在这里，我比较了两种基于模型的诱发（刺激锁定）SCR 分析方法，这两种方法在 SCRalyze 和 Ledalab 两个软件包中实施，并比较了它们在恢复 SA 方面的灵敏度。分析四个数据集以比较预测有效性，即区分已知不同的 SA 状态对的敏感性。 SCRalyze 明显比 Ledalab 能够更好地在五分之四的测试对比中恢复这一已知差异，并且在其余对比中具有可比性。 SCRalyze 在所有对比中均明显优于传统分析。我的结论是，SCRalyze 中产生的基于模型的方法是目前提供稳健且灵敏的交感神经唤醒估计的最佳可用方法。
Comparison of two developed methods for model-based analysis of phasic skin conductance responses. Four datasets are used to compare predictive validity. SCRalyze shows higher predictive validity than Ledalab in 4 of 5 comparisons, and equal predictive validity in the fifth. SCRalyze shows higher predictive validity than peak-scoring in all comparisons. Model-based analysis of skin conductance responses (SCR) can furnish less noisy estimates of sympathetic arousal (SA) than operational peak scoring approaches, as shown in previous work. Here, I compare two model-based methods for analysis of evoked (stimulus-locked) SCR, implemented in two software packages, SCRalyze and Ledalab, with respect to their sensitivity in recovering SA. Four datasets are analysed to compare predictive validity, i.e. the sensitivity to distinguish pairs of SA states that are known to be different. SCRalyze was significantly better able than Ledalab to recover this known difference in four out of five tested contrasts and comparable in the remaining one. SCRalyze performed significantly better than conventional analysis in all contrasts. I conclude that the model-based method engendered in SCRalyze is currently the best available approach to provide robust and sensitive estimates of sympathetic arousal.
