Subclaims¶

q3 i? Initial accuracy after the second intervention further increased by about 12 points in the training group versus about 1.5 points in control. → Nina Franiatte 2024 q3 i? Final accuracy after the second intervention further increased by 11.2 points in the training group, with a marginally significant Block x Group interaction. → Nina Franiatte 2024 (2)

q3 · i? · causal · r2

Session 2 of the same preregistered online experiment (110 of 120 participants re-tested): the main initial accuracy effect was significant, χ2 (1) = 50.9, p < .001, and the Block x Group interaction for initial responses reached marginal significance, χ2 (1) = 3.5, p = .06.

"initial accuracy after the second intervention further increased by 12 .0 points (control group: +1.5 points) , reaching M = 80.5%, SD = 24.9 in the post-intervention block."

Session 2 final-response analysis: main final accuracy significantly improved, χ2 (1) = 55.7, p < .001, and the Block x Group interaction for final responses reached marginal significance, χ2 (1) = 3.9, p = .05.

"final accuracy after the second intervention further increased by 11.2 points (control group: - 0.3 point), reaching M = 85.6%, SD = 22.7 in the post-intervention block."
