q3 i? Neither accuracy in the mixed block of HF nor the shift cost was associated with intelligence or WM (all ps > .181). → Ger Ebru 2023

q3 · i? · associational · r2

Correlational analyses in the N = 147 sample found no associations between shifting measures (mixed-block accuracy, shift cost) and intelligence or either WM component. The shift cost itself was not significantly different from zero (p = 1), consistent with Roebers (2022) finding no shift cost in 6-year-olds.

"neither accuracy in the mixed block of HF nor the shift cost (i.e., time taken to shift between rules) was associated with either intelligence or WM (all ps > .181)"
