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 i? PS was linked to WM in both studies; Study 1 showed equal links from PS to STM and WM, but Study 2 showed a link from PS only to WM. → Robert Kail and Lynda K. Hall 2001

Structural equation models compared four configurations linking processing speed (Visual Matching and Cross-Out) to memory. In Study 1, removing either PS path worsened fit (c2s(1) = 9.86 and 14.29, p < .01); in Study 2, the PS-to-STM-only model fit poorly (c2(1) = 33.76, p < .01). "Study 1 yielded equal links from PS to STM and WM, but Study 2 resulted in a link from PS to WM only."
"Study 1 yielded equal links from PS to STM and WM, but Study 2 resulted in a link from PS to WM only."
Discussion¶
Related Claims¶
- Working memory, but not short-term memory, predicts word decoding skill in children — related
- Working memory is distinct from short-term memory in subsystem count and functional role in higher cognition — a broader claim this one bears on
- The two-factor STM/WM structure holds for both younger (8-10) and older (11-13) children — related
