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? With variance shared between WM and STM factored out, path coefficients from WM to decoding were significant (.41 and .53) while those from STM to decoding (.14 and .08) were not. → Robert Kail and Lynda K. Hall 2001

Structural equation modeling, modeled after Engle, Tuholski, et al. (1999), estimated unique contributions of WM and STM to PIAT-R Reading Recognition scores in both studies. "The coefficients from WM to decoding—.41 and .53 in Studies 1 and 2, respectively—were significant", whereas STM paths were not; model comparisons also favored a WM-only link (c2s(1) = 10.82 and 15.84, p < .01).
"The coefficients from WM to decoding—.41 and .53 in Studies 1 and 2, respectively—were significant ( ts $ 3.77, p , .05), but those from STM to decoding—.14 and .08 in Studies 1 and 2, respectively—were not (ts # 1.24)."
Discussion¶
Related Claims¶
- Working memory is distinct from short-term memory in subsystem count and functional role in higher cognition — a broader claim this one bears on
- Processing speed is linked to working memory in both studies, but its link to short-term memory is inconsistent across studies — related
