Note. “BA” = Bird/Alligator; “SS” = Shape Stroop; “GS = Grass/Snow”; “PR” and “SCR” are parent and secondary caregiver reports, respectively, on the Inhibitory Control scale from the Children’s Behavior Questionnaire–Short Form. Fisher’s r-to-z tests compare the magnitude of two associations. The power to detect differences in the magnitude of correlations is considerably lower than the power to detect bivariate associations, so we also provide effect sizes of Fisher’s r-to-z tests with Cohen’s q, which reflects the magnitude of the difference between two correlation coefficients (Cohen, 1988). For simplicity, some Fisher’s r-to-z tests are not shown due to non-significant bivariate correlations, for which the associations would not be expected to have significantly different magnitude.
