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? SIM-NEW shares only the number of participants with the PALMA dataset and assumes ASC and ACH are fully determined by one latent ability factor, despite meta-analytic correlations around r = .30. → Núñez-Regueiro 2026

q2 · i? · theoretical · r3
Critique of the SIM-NEW data-generating model: it collapses ASC and ACH into one latent factor, whereas meta-analyses report a moderate correlation "around r =.30"; the data are entirely simulated and analysed with a non-REM time-reversed model.
"the simulation model assumes that both ASC and ACH are fully determined by a single latent “ability” factor, thereby collapsing two distinct psychological constructs into one, despite meta-analytic evidence showing that they are only moderately correlated (around r =.30)"
Discussion¶
Related Claims¶
- The RI-CCLPM-C indicates a positive self-concept effect on achievement even when data are generated without any direct effects between self-concept and achievement — related
- Time-reversed analysis of simulated data suggests a decreasing rather than increasing effect of self-concept on achievement, yielding inconsistent conclusions from the same data — related
- The alternative models proposed by Sorjonen et al. relied on specifications that raised model-validity concerns or did not fully capture the extended REM's temporal structure — related
- Reanalyses of simulated and PALMA data provide converging support for the extended reciprocal effects model, including an effect of academic self-concept on achievement — related
