Note(s): p 0.01**p* The motivation-related variables (Items 1–3) in the first column were measured on 7-point scales, the scale for EF (item 6) = 4 and learning (items 4–5) = 5. The correlation coefficients were deemed a small effect when r < 0.3, a medium effect when r ≥ 0.3 and a large effect when r ≥ 0.5
