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 High self-efficacy groups exhibited significantly greater changes in visual discrimination thresholds than low self-efficacy groups in both the orientation task (d = 20.68) and the contrast task (d = 20.86). → Zacharopoulos G 2014
Evidence¶
Zacharopoulos G 2014¶
Zacharopoulos G, Binetti N, Walsh V, Kanai R (2014) The Effect of Self-Efficacy on Visual Discrimination Sensitivity. PLoS ONE 9(10): e109392. https://doi.org/10.1371/journal.pone.0109392
q3 · i3 · causal · r2
Controlled lab experiment with 118 participants randomly assigned to high, low or control self-efficacy groups in contrast or orientation discrimination tasks. Independent-samples t-tests showed orientation t(40) = 22.205, p = .033; d = 20.68; contrast t(36) = 22.652, p = 0.012; d = 20.86, indicating "a significant difference in the changes in VDS".
"There was a significant difference in the changes in VDS between the positive feedback group (orientation, M = 2.727, SD = 1.093, contrast, M = 2.019, SD = .027) and the negative feedback group"
Discussion¶
Related Claims¶
- Control groups show no significant pre-to-post change in visual discrimination thresholds, indicating the two blocks did not interact — related
- Fake social-comparative feedback combined with fictional malleability information successfully induces large changes in self-efficacy beliefs — related
- Mixed-design ANOVAs reveal significant group-by-time interactions on visual discrimination sensitivity in both tasks — related
- Changes in self-efficacy correlate with changes in visual discrimination sensitivity after regressing out objective ability and baseline self-efficacy — related
