Note. Effect sizes are all statistically significant, p < .01, except those in italics. Directions of the effects are indicated for each subtest. A + indicates that the scores based on the Dutch norms > scores based on the US norms. A–indicates that that the scores based on the Dutch norms <scores based on the US norms
