q3 i2 Both mean tonic and mean phasic GSR activity were significantly higher during low- than high-interest segments (d=0.76 and d=0.63), opposite to the expected direction. → Levy 2025

Paired comparisons of GSR metrics across high vs low-interest segments in the lab study (n=32). The authors had expected higher arousal for high-interest content; "Cohen’s d=0.76" (tonic) and "Cohen’s d=0.63" (phasic) were printed for the observed direction.

"Both main metrics showed significantly higher activity during low - compared to high-interest segments [mean tonic activity: t(31)=4.326, p<0.001 , Cohen’s d=0.76 ; mean phasic activity: t(31)=3.566, p=0.001, Cohen’s d=0.63; Figure 4]."
