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? Children with more variable WM performance at all timescales had lower school achievement. → Dirk 2016

q3 · i? · associational · r?
Correlational finding from the ambulatory assessment study; the article reports more variable WM performance "was related to lower school achievement". No effect size is printed.
"more variable WM performance at all timescales was related to lower school achievement, and more day-to-day variability was associated with lower fluid intelligence."
Discussion¶
Related Claims¶
- More day-to-day WM variability is associated with lower fluid intelligence — related
- Grade 3 students are more variable than Grade 4 students in WM performance at the faster timescales — related
- Day-to-day, occasion-to-occasion, and moment-to-moment variability each account for roughly the same extent of observed daily WM variability, with large individual differences — related
