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 i2 Suddenness reliably decreased as a function of RAPM item difficulty with a moderate effect size. → Adam Chuderski 2021 q3 i3 Certainty reliably decreased as a function of RAPM item difficulty with a strong effect size. → Adam Chuderski 2021 (2)

q3 · i2 · associational · r2

BANOVA on 1017 correct-solution ratings across 20 RAPM items with participant as random factor, in a study of 100 adults. The article reports Suddenness "reliably decreased as a function of the item difficulty" with ηp2 = .07, BF10 > 999.

"Suddenness reliably decreased as a function of the item difficulty, BF 10 > 999, and yielded a moderate effect size of ηp2 = .07."

q3 · i3 · associational · r2

Same BANOVA on correct-solution ratings across the 20 RAPM items. Certainty showed a strong difficulty effect, ηp2 = .24, BF10 > 999, and Pleasure yielded a virtually identical effect.

"A reliable effect was observed also for Certainty, BF 10 > 999, and it was strong, ηp2 = .24 (Pleasure yielded a virtually identical effect)."
