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's daily working memory performance fluctuates substantially within person across days in school. → Dirk 2016

Ambulatory assessment study in which Grade 3 and Grade 4 students (8 to 11 years old; N ! 110) completed WM tasks on smartphones 3 times a day in school and at home for 4 weeks; the article reports "substantial within-person fluctuations in children's daily WM performance".
"Results showed substantial within-person fluctuations in children's daily WM performance."
Discussion¶
Related Claims¶
- Elementary school children show substantial day-to-day within-person fluctuations in sleep quality, time in bed, daytime tiredness, and working memory performance — a broader claim this one bears on
- Current daytime tiredness predicts children's afternoon working memory performance fluctuations — related
- Children with lower average working memory performance show stronger within-person coupling between nightly sleep quality and morning performance — related
- Previous night's sleep quality and time in bed predict children's morning working memory performance fluctuations — 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
