We estimated regions of significance55 to further test the DSH hypotheses.56 In study 1, positive affect differed significantly between the genotypes when positive parenting was lower than 1.23 s.d. or higher than 0.87 s.d. than the mean score on the Alabama Parenting Questionnaire (Figure 1). In study 2, positive affect differed significantly between the genotypes at the two least supporting levels of observed parenting (Figure 2). In study 3, positive affect differed significantly between the genotypes below 2.3 and above 3.5 points on the 1–4 EMBU warmth scale (Figure 3).
