q2 · i3 · review · r?

The supplementary materials report, citing Pijeira-Díaz et al. (2018), a small classroom study (N = 24) using Ledalab's deconvolution to extract phasic EDA, which showed a "strong correlation (r = .66)" with achievement. The review attributes this to that study.

"Despite involving relatively few students (N = 24), this study illustrated the trend of moving from tonic to phasic EDA, finding a strong correlation (r = .66) between phasic EDA and achievement."
