“…In contrast, we observed tremendous variation in the quantification of the autonomic indices. For example, studies on skin conductance level during reappraisal assessed baseline activity during a neutral condition that included the presentation of neutral stimuli (Wolgast et al, 2011;Lohani and Isaacowitz, 2014), right before stimulus onset (e.g., Shiota and Levenson, 2009), right before instruction (Opitz et al, 2014), after instruction , or reported no baseline assessment (Goldin et al, 2019). These studies then either subtracted mean activity of the respective baseline from mean activity during the regulation period (e.g., Shiota and Levenson, 2009;Opitz et al, 2014), calculated raw means (Goldin et al, 2019), or area under the curve .…”
