Table 1.
Comparison of predictive validity. The table shows Log Bayes Factors (LBFs), for the comparison of two experimental conditions. The two conditions are assumed to differ in sympathetic arousal (SA) such that lower LBF-values indicate better sensitivity of the respective method to recover that difference. LBFs are expressed with reference to the SCRalyze GLM. An absolute LBF difference of more than 3 is usually considered significant and corresponds to a classical p-value of p < .05. t-Scores for paired t-tests on the condition differences are given in brackets. GLM: estimated SA amplitude from the general linear model in SCRalyze. DDA 1: sum of estimated SCR amplitudes of significant SCRs from non-negative deconvolution in Ledalab; DDA 2: sum of estimated SCR area of significant SCRs from non-negative deconvolution in Ledalab, CDA 1: sum of estimated SCR amplitudes of above-threshold SCRs from continuous deconvolution in Ledalab; CDA 2: average estimated phasic driver from continuous deconvolution in Ledalab.
