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? Post-assessment correlations among the LPCI, GSA, and PSVT-Rot were significant for every group except control males on PSVT-Rot versus LPCI, which the authors take as supporting a connection between spatial reasoning and lunar-related understanding. → Jennifer Wilhelm 2009

q2 · i? · causal · r1
Correlational analysis of post-test scores (Table 8), e.g. control all: LPCI-GSA r = 0.543, PSVT-Rot-GSA r = 0.511, PSVT-Rot-LPCI r = 0.431, all p < 0.05. This is a correlational result, not a causal test of the spatial-reasoning claim.
