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 ...
Gene-environment correlation linking aggression and peer victimization : do classroom behavioral norms matter?
Using a genetically informed design based on 197 Monozygotic and Dizygotic twin pairs assessed in grade 4, this study examined 1) whether, in line with a gene-environment correlation (rGE), a genetic disposition for physical ...
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 ...
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
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 expression of genetic risk for aggressive and non-aggressive antisocial behavior is moderated by peer group
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 ...

(Australian Academic Press, 2016-04)
We analyzed birth order differences in means and variances of height and body mass index (BMI) in monozygotic (MZ) and dizygotic (DZ) twins from infancy to old age. The data were derived from the international CODATwins ...
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 ...
