  • Machine learning to analyze single-case data : a proof of concept 

    Lanovaz, Marc; Giannakakos, Antonia R.; Destras, Océane (Springer, 2020)
    Visual analysis is the most commonly used method for interpreting data from singlecase designs, but levels of interrater agreement remain a concern. Although structured aids to visual analysis such as the dual-criteria (DC) method may increase ...

    Lanovaz, Marc; Adams, Bram (Institute of Electrical and Electronics Engineers, 2019-06-19)
    The R programming language has an active community of both users and developers, which maintain mailing lists to communicate. Given their differences in training and stability, the effects of communication tone on responding may differ across these ...

  • Genetic and environmental influences on developmental trajectories of adolescent alcohol use 

    Zheng, Yao; Brendgen, Mara; Dionne, Ginette; Boivin, Michel; Vitaro, Frank (Springer, 2019-01-31)

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

    Visual structured criterion
    Lanovaz, Marc; Cardinal, Patrick; Francis, Mary (SAGE, 2019-01)
    Although visual inspection remains common in the analysis of single-case designs, the lack of agreement between raters is an issue that may seriously compromise its validity. Thus, the purpose of our study was to develop and examine the properties ...
  • Longitudinal links between gambling participation and academic performance in youth : a test of four models 

    Gambling participation and academic achievement
    Vitaro, Frank; Brendgen, Mara; Girard, Alain; Dionne, Ginette; Boivin, Michel (Springer, 2018-09-30)
    Gambling participation and low academic performance are related during adolescence, but the causal mechanisms underlying this link are unclear. It is possible that gambling participation impairs academic performance. Alternatively, the link between ...
  • Serotonin transporter promoter methylation in peripheral cells and neural responses to negative stimuli : a study of adolescent monozygotic twins 

    Ismaylova, Elmira; Lévesque, Melissa; Pomares, Florence B.; Szyf, Moshe; Nemoda, Zsofia; Fahim, Cherine; Vitaro, Frank; Brendgen, Mara; Dionne, Ginette; Boivin, Michel; Tremblay, Richard Ernest; Booij, Linda (Springer Nature, 2018-08-08)

  • 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 single-case designs in practical settings: Is replication always necessary? 

    Is within-subject replication always necessary?
    Lanovaz, Marc; Turgeon, Stéphanie; Cardinal, Patrick; Wheatley, Tara L. (Springer, 2018-05-17)
    Behavior analysts have widely adopted and embraced within-subject replication through the use of reversal and multielement designs. However, the withdrawal of treatment, which is central to these designs, may not be desirable, feasible, or even ethical ...
