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 i? In both experiments, triggered and maintained situational interest did not differ between the pictures and no-pictures conditions; in Experiment 2 maintained situational interest was significantly lower with pictures. → Demian Scherer 2023

Demian Scherer, Annika Verkühlen, Stephan Dutke. (2023). Effects of related decorative pictures on learning and metacognition. Instructional Science. https://doi.org/10.1007/s11251-023-09618-8

q3 · i? · causal · r2

Experiment 2 ANCOVA (topic interest as covariate) on the behavioral take-home text choice measure showed reduced maintained interest with pictures, ηp2 = .095. The authors call this "a puzzling finding" and note it may reflect higher sensitivity of the measure or be incidental.

"Regarding maintained situational interest, participants in the group with related decorative pictures indicated to take less materials with them to read (M = 1.62, SD = 1.54) compared to the control group (M = 2.00, SD = 1.39), F(1, 53) = 5.56, p = .022, ηp2 = .095."
