  1. Values presented are mean ± standard deviation. CT task and ST task refer to the continuous tracking and serial targeting tasks. Age units are in years and peak oxygen uptake (V̇O2peak) units are in ml/kg/min. Values in the BDNF met carrier and DRD2/ANKK1 lys carrier columns represent data combining the heterozygote and homozygote carriers of the minor alleles, with values in parentheses representing only the characteristics of the met/met or lys/lys homozygotes within the larger carrier group.
