  • Contribution of genes and environment to the longitudinal association between childhood impulsive‐aggression and suicidality in adolescence 

    Orri, Massimiliano; Geoffroy, Marie-Claude; Turecki, Gustavo; Feng, Bei; Brendgen, Mara; Vitaro, Frank; Dionne, Ginette; Paquin, Stéphane; Galera, Cedric; Renaud, Johanne; Tremblay, Richard Ernest; Côté, Sylvana; Boivin, Michel (Wiley, 2019-11-28)
    Background Population‐based and family studies showed that impulsive‐aggression predicts suicidality; however, the underlying etiological nature of this association is poorly understood. The objective was to determine the contribution of genes and ...
  • The genetic and environmental etiology of the association between vocabulary and syntax in first grade 

    Etiology of vocabulary and syntax
    Mimeau, Catherine; Dionne, Ginette; Feng, Bei; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard Ernest; Boivin, Michel (Taylor & Francis, 2018-03-09)
    This study examined the genetic and environmental etiology of vocabulary, syntax, and their association in first graders. French-speaking same-sex twins (N = 555) completed two vocabulary tests, and two scores of syntax were calculated from their ...
  • A longitudinal twin study of callous-unemotional traits during childhood 

    Longitudinal twin callous-unemotional, 1
    Henry, Jeffrey; Dionne, Ginette; Viding, Essi; Petitclerc, Amélie; Feng, Bei; Vitaro, Frank; Brendgen, Mara; Tremblay, Richard Ernest; Boivin, Michel (American Psychological Association, 2018-05)
    Previous research indicates that genetic factors largely account for the stability of callous-unemotional (CU) traits in adolescence. However, the genetic-environmental etiology of the development of CU traits has not been extensively investigated in ...
  • Persistent genetic and family-wide environmental contributions to early number knowledge and later achievement in mathematics 

    Etiology of early math knowledge and skills development
    Garon-Carrier, Gabrielle; Boivin, Michel; Kovas, Yulia; Feng, Bei; Brendgen, Mara; Vitaro, Frank; Séguin, Jean; Tremblay, Richard Ernest; Dionne, Ginette (SAGE, 2017-10-03)
    This study investigated the stable and transient genetic and environmental contributions to individual differences in number knowledge in the transition from preschool (age 5) to Grade 1 (age 7) and to the predictive association between early number ...
