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? The review reports that a battery of gamified spatial measures given to twin pairs indicated a one-factor model of spatial ability fit better than a two-factor model, even controlling for a common genetic factor. → Kelsey E. Schenck 2024

q2 · i? · review · r2
Narrative review attributing this to Rimfeld et al. (2017), who administered a battery of gamified spatial measures to twin pairs; the one-factor model fit best. The review also cites Malanchini et al. (2020) finding the one-factor model gave the best fit even controlling for general intelligence. No effect size is printed.
"results indicated that tests assessed a single spatial ability factor and that the one-factor model of spatial ability fit better than the two-factor model, even when controlling for a common genetic factor (Rimfeld et al., 2017)."

- Perspective-taking (spatial orientation) shows evidence of uniqueness from mental rotation factors — reports the opposite
