q3 i? Grade 3 students showed more WM performance variability than Grade 4 students at the faster (occasion and moment) timescales. → Dirk 2016

q3 · i? · associational · r2

Group comparison from the ambulatory assessment study (N ! 110, Grades 3 and 4); the article reports "Grade 3 students were more variable than were Grade 4 students at the faster timescales". No effect size is printed.

"Grade 3 students were more variable than were Grade 4 students at the faster timescales, 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¶

• 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
• More variable WM performance at all timescales is related to lower school achievement — related
