  • Early warm-rewarding parenting moderates the genetic contributions to callous-unemotional traits in childhood 

    Warm-rewarding genetic callous-unemotional
    Henry, Jeffrey; Dionne, Ginette; Viding, Essi; Vitaro, Frank; Brendgen, Mara; Tremblay, Richard Ernest; Boivin, Michel (Wiley, 2018-04-23)
    Background Previous gene–environment interaction studies of CU traits have relied on the candidate gene approach, which does not account for the entire genetic load of complex phenotypes. Moreover, these studies have not examined the role of positive ...

  • A longitudinal twin study of callous-unemotional traits during childhood 

    Longitudinal twin callous-unemotional, 1
