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? Correlations among tasks thought to measure the same memory construct (STM or WM) were larger than correlations between tasks measuring different constructs. → Robert Kail and Lynda K. Hall 2001

q3 · i? · associational · r2
Analysis of the correlation matrices (Table 1) from Study 1 (N = 155) and Study 2 (N = 142) showed all measures correlated positively, with same-construct rs of ".36 to .47, with a median of .45" versus different-construct rs with a median of .26. All Study 1 rs were significant at p < .05.
"the 5 rs from tasks involving the same memory construct ranged from .36 to .47, with a median of .45; the 10 rs from tasks involving different memory con- structs ranged from .19 to .32, with a median of .26."
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
- Working memory capacity is significantly smaller in lower-SES than higher-SES adolescents — related
- The two-factor STM/WM structure holds for both younger (8-10) and older (11-13) children — related
