However, a highly significant effect of Valence was found for Bias [ F (1,35) = 29.11, p < 0.001, η p 2 = 0.45], with significantly higher bias for negative words, and also a main effect of Genotype [ F (1,35) = 6.56, p = 0.02, η p 2 = 0.16], with significantly lower bias in Met carriers than Val homozygotes (see Figure 1 ).
