Delayed recognition memory organized by stress and carriers of the risk allele for the three FKBP5 SNPs. Stress selectively enhanced long-term recognition memory for non-arousing words (a). For each of the three SNPs (b, c, d), stress enhanced long-term recognition memory in non-carriers of the risk allele, relative to non-stressed non-carriers, but had no effect on carriers. * P < 0.01 relative to non-arousing word recognition in non-stressed participants or overall recognition memory in non-stressed non-carriers.
