  • Social contagion and high school dropout : the role of friends, romantic partners, and siblings 

    Dupéré, Véronique; Dion, Éric; Cantin, Stéphane; Archambault, Isabelle; Lacourse, Éric (American Psychological Association, 2020-06-18)
    Social contagion theories suggest that adolescents in relationships with same-age high school dropouts should be at a greater risk of dropping out themselves. Yet, few studies have examined this premise, and none have considered all potentially influential ...
  • Some characteristics and arguments in favor of a science of machine behavior analysis 

    Lanovaz, Marc (Springer, 2022-03-31)
    Researchers and practitioners recognize four domains of behavior analysis: radical behaviorism, the experimental analysis of behavior, applied behavior analysis, and the practice of behavior analysis. Given the omnipresence of technology in every sphere ...

    Dupéré, Véronique; Leventhal, Tama; Dion, Éric; Crosnoe, Robert; Archambault, Isabelle; Janosz, Michel (2015-12)
    High school dropout is commonly seen as the result of a long-term process of failure and disengagement. As useful as it is, this view has obscured the heterogeneity of pathways leading to dropout. Research suggests, for instance, that some students ...

  • Twin classroom dilemma : to study together or separately? 

    White, Elaine K.; Garon-Carrier, Gabrielle; Tosto, Maria G.; Malykh, Sergey B.; Li, Xinying; Kiddle, Beata; Riglin, Lucy; Byrne, Brian; Dionne, Ginette; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard Ernest; Boivin, Michel; Kovas, Yulia (American Psychological Association, 2018-07)
    There is little research to date on the academic implications of teaching twins in the same or different classroom. Consequently, it is not clear whether twin classroom separation is associated with positive or negative educational outcomes. As a result, ...

  • Using a visual structured criterion for the analysis of alternating-treatment designs 

    Visual structured criterion
    Lanovaz, Marc; Cardinal, Patrick; Francis, Mary (SAGE, 2019-01)
