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 ...
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 ...
A prospective, longitudinal, study of men with borderline personality disorder with and without comorbid antisocial personality disorder
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 ...
Links between friends' physical aggression and adolescents' physical aggression : what happens if gene-environment correlations are controlled?
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 ...
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 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 ...
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 ...
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 ...
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 ...
Early warm-rewarding parenting moderates the genetic contributions to callous-unemotional traits in childhood
Warm-rewarding genetic callous-unemotional
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 ...
