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 i1 Trials eliciting positive image RPEs in which participants gambled or observed gambling were associated with enhanced memory (EL d = 0.30; OL d = 0.27), whereas pass trials were not. → Maria A. Woitow 2026

q3 · i1 · causal · r2
Exploratory one-sample t-tests on memory performance for positive image RPE trials in 79 participants: EL d = 0.30 (t78 = 2.66, p = 0.009), OL d = 0.27 (t78 = 2.37, p = 0.02); "pass trials were not" significant, and negative RPE trials did not differ from average.
"Trials eliciting positive RPEs in which participants gambled or observed gambling were associated with enhanced memory (EL: t78 = 2.66, p = 0.009, d = 0.30, 95% CI = 0.03–0.19; OL: t78 = 2.37, p = 0.02, d = 0.27, 95% CI = 0.01–0.16; one- sample t-tests against 0"
Discussion¶
Related Claims¶
- Competitive attitudes toward the observed player predict memory strength in experiential but not observational learning — related
- More extreme potential reward values are associated with reduced memory strength across learning conditions and choices — related
- Feedback-stage reward prediction errors, signed or unsigned, do not modulate memory in either learning condition — reports the opposite
- Choosing to gamble enhances both memory accuracy and memory strength in experiential and observational learning alike — related
- Recognition accuracy for incidentally encoded images does not significantly differ between experiential and observational learning conditions — related
