Adolescent cannabis use, change in neurocognitive function, and High-School Graduation : a longitudinal study from early adolescence to young adulthood
(Cambridge University Press, 2017-10)The main objective of this prospective longitudinal study was to investigate bidirectional associations between adolescent cannabis use (CU) and neurocognitive performance in a community sample of 294 young men from ages 13 to 20 years. The results ... -
Associations between daily mood states and brain gray matter volume, resting-state functional connectivity and task-based activity in healthy adults
(Frontiers Media, 2018-05-01)Numerous studies have shown differences in the functioning in the areas of the frontal-limbic circuitry between depressed patients and controls. However, current knowledge on frontal-limbic neural substrates of individual differences in mood states in ... -
Commentary : On the importance of looking at nonlinearity and developmental effects – a reflection on Flom et al. (2017)
(Wiley, 2017-04-17)By examining both linear and curvilinear associations between mental development and activity level, the study by Flom et al. (Journal of Child Psychology and Psychiatry, 2017) highlights the importance of going beyond linear associations in psychological ... -
Early warm-rewarding parenting moderates the genetic contributions to callous-unemotional traits in childhood
Warm-rewarding genetic callous-unemotional
(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 ... -
The expression of genetic risk for aggressive and non-aggressive antisocial behavior is moderated by peer group
(Springer, 2015-07)Numerous studies have shown that aggressive and non-aggressive antisocial behaviors are important precursors of later adjustment problems. There is also strong empirical evidence that both types of antisocial behavior are partially influenced by genetic ... -
The genetic and environmental etiology of the association between vocabulary and syntax in first grade
Etiology of vocabulary and syntax
(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 ... -
Heterogeneity in the development of proactive and reactive aggression in childhood : Common and specific genetic-environmental factors
(Public Library of Science, 2017-12-06)Background Few studies are grounded in a developmental framework to study proactive and reactive aggression. Furthermore, although distinctive correlates, predictors and outcomes have been highlighted, proactive and reactive aggression are substantially ... -
The interaction between temperament and the family environment in adolescent substance use and externalizing behaviors : support for diathesis–stress or differential susceptibility?
(Elsevier, 2016-06)Both individual and environmental factors predict externalizing behaviors and substance use (EB-SU); however, different patterns of interaction among these factors may have different implications. This review first examines how temperament and the ... -
Links between friends' physical aggression and adolescents' physical aggression : what happens if gene-environment correlations are controlled?
(Sage, 2016-05)Exposure to deviant friends has been found to be a powerful source of influence on children’s and adolescents’ aggressive behavior. However, the contribution of deviant friends may have been overestimated because of a possible non-accounted gene-environment ... -
A longitudinal twin study of callous-unemotional traits during childhood
Longitudinal twin callous-unemotional, 1
(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 ... -
Modelling vocabulary development among multilingual children prior to and following the transition to school entry
(Taylor & Francis, 2017-01-03)Differences between monolingual and multilingual vocabulary development have been observed but few studies provide a longitudinal perspective on vocabulary development before and following school entry. This study compares vocabulary growth profiles ... -
Municipal regulation of cannabis and public health in Canada : a comparison of Alberta, Ontario, and Québec
(Wiley, 2022-04-25)Canada legalized nonmedical cannabis in October 2018, but significant variations in municipal regulations exist. This study explored the variations that exist and pondered their potential public health consequences. A comparative analysis was completed ... -
Persistence and innovation effects in genetic and environmental factors in negative emotionality during infancy : a twin study
(Public Library of Science, 2017-04-27)Background Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing psychopathology, including depression and anxiety. A better understanding of the roots of difficult temperament requires assessment of its ... -
Phenotypic and genetic associations between reading comprehension, decoding skills, and ADHD dimensions : evidence from two population-based studies
Phenotypic and genetic associations between reading and ADHD
(Wiley, 2015-02)BACKGROUND: The phenotypic and genetic associations between decoding skills and ADHD dimensions have been documented but less is known about the association with reading comprehension. The aim of the study is to document the phenotypic and genetic ... -
A prospective, longitudinal, study of men with borderline personality disorder with and without comorbid antisocial personality disorder
(BMC, 2017-12)Background: Some evidence suggests that the prevalence of Borderline Personality Disorder (BPD) is elevated among male criminal offenders. It is not presently known whether offending, and violent offending, are limited to those presenting comorbid ... -
Risk factors associated with driving after cannabis use among Canadian young adults
(SAGE, 2021-10-11)This study identifid the most prominent risk factors associated with driving after cannabis use (DACU). 1,126 Canadian drivers (17–35 years old) who have used cannabis in the past 12 months completed an online questionnaire about sociodemographic ... -
Twin classroom dilemma : to study together or separately?
(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, ... -
Typologies of Canadian young adults who drive after cannabis use : a two-step cluster analysis
(Wiley, 2022-01-31)Young adults that drive after cannabis use (DACU) may not share all the same characteristics. This study aimed to iden-tify typologies of Canadians who engage in DACU. About 910 cannabis users with a driver's license (17–35years old) who have ... -
