Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i3 Interest-level ratings for lecture segments were highly correlated between an online screening study and the EEG lab study, supporting them as objective metrics of situational interest. → Levy 2025

q3 · i3 · causal · r2

Lab study (n=32) and online screening (n=37) both rated 63 lecture segments for interest on a 1-7 scale. Segment-level variation in interest was highly correlated across cohorts ("Pearson's r = 0.827"), indicating group-level ratings capture common interest fluctuations.

"variation in interest-level ratings for the different lecture-segments, where highly correlated between the two studies [Pearson's r = 0.827, p<0.001"
