Numbers represent correct responses, standard deviations in parentheses (whole sample, n = 429). Results of dependent variables of T/C polymorphism in NRG1 as entered in ANOVA, standard deviations are in parentheses.

Abbreviations for the newly reported tests: attention = number of correctly marked items in the attention task (d2 rest; Brickenkamp, 2002). L‐N‐S = letter number span [Gold et al., 1997]. TMT‐B = trail making test B [Reitan and Wolfson, 1985]. NS = nonsignificant (all P > 0.1).
