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 i? The 3x2 mixed-design ANOVA on VDS changes showed a significant group (high, low, control) by time (pre, post) interaction in the orientation task, F(2,59) = 3.450, p = .038, and in the contrast task, F(2,53) = 3.307, p = .044. → Zacharopoulos G 2014

q3 · i? · causal · r2
Omnibus analysis of the 118-participant experiment: 3x2 mixed-design ANOVA with SE group as between-subject factor and phase as within-subject factor on VDS changes. The contrast task interaction was F(2,53) = 3.307, p = .044; only test statistics are printed, no effect size.
"In the orientation task there was a significant interaction between group (i.e. high, low, control) and time (i.e. pre-manipulation, post-manipula- tion), F(2,59) = 3.450, p = .038."
Discussion¶
Related Claims¶
- Control groups show no significant pre-to-post change in visual discrimination thresholds, indicating the two blocks did not interact — related
- Participants induced to hold high self-efficacy show greater improvement in visual discrimination sensitivity than participants induced to hold low self-efficacy — related
- Changes in self-efficacy correlate with changes in visual discrimination sensitivity after regressing out objective ability and baseline self-efficacy — related
- Fake social-comparative feedback combined with fictional malleability information successfully induces large changes in self-efficacy beliefs — related
