Similar to some previous reports (Barton et al., 2014; Erickson et al., 2008; Gajewski et al., 2011; Getzmann et al., 2013), we found paradoxical results for the BDNF met allele in relation to behavior. That is, we found that BDNF met homozygotes performed superior to the val allele carriers in the sequence learning task. Therefore, in addition to the conventional analyses, we performed an exploratory post hoc analysis for the sequence- learning task (results are presented in Appendix C) with the BDNF met allele coded as the high performance allele (i.e.reverse coding).
