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.
q2 i? With a 1-h retention delay, the OC group showed significantly higher object category recognition performance than the SH group and discriminated the novel category above chance. → Gattas 2022

q2 · i? · causal · r2
Object category recognition task (sample 10 min; delays 30 min and 1 h) in the four-group design. Paired-samples t-tests showed the OC, t(9) = −5.895, p < 0.001, and EH, t(9) = −2.937, p = 0.017, groups discriminated the novel category at 1 h; no effect size is printed for the OC vs SH contrast.
"planned comparisons using independent samples t-tests revealed a significant difference in group performance on the task between the OC and the SH group, t(18) = 3.884, p = 0.001, when the delay was 1 h."
Discussion¶
Learner Variables¶
- Visual Processing — outcome: instruction changes it
