q2 i? In a study of deep-sea divers undergoing a Stroop task, tonic EDA changes were not correlated with stress while phasic EDA showed a correlation with cognitive stress using spectral analysis. → Kennett 2025

q2 · i? · associational · r?

The supplementary materials report, citing Posada-Quintero et al. (2018), a study of stress in deep-sea divers in which spectral analysis linked "cognitive stress and phasic EDA" while tonic changes were uncorrelated with stress. No effect size is printed.

"The authors found that tonic changes were not correlated with stress, but using spectral analysis (Fast Fourier Transform), they showed a correlation between cognitive stress and phasic EDA in divers undergoing a Stroop task."
