The dark side of friends : a genetically informed study of victimization within early adolescents’ friendships
(Taylor & Francis, 2015)
Using a genetically informed twin design, this study examined (a) whether, in line with gene–environment correlation (rGE), a genetic disposition for anxiety puts children at risk of being victimized by a close friend or ...
Contagion of anxiety symptoms among adolescent siblings : a twin study
(Wiley, 2017-03)
This study examined whether social contagion of anxiety symptoms is present between siblings during early adolescence and whether this process is moderated by sex, relationship quality, and zygosity. Based on 634 monozygotic ...
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 ...
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 ...
Twin’s birth-order differences in height and body mass index from birth to old age: a pooled study of 26 twin cohorts participated in the CODATwins project
(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 ...
Serotonin transporter promoter methylation in peripheral cells and neural responses to negative stimuli : a study of adolescent monozygotic twins
(Springer Nature, 2018-08-08)
Several studies have examined associations between peripheral DNA methylation patterns of the serotonin transporter
gene (SLC6A4) promoter and symptoms of depression and anxiety. The SLC6A4 promoter methylation has also ...
Genetic and environmental influences on height from infancy to early adulthood : an individualbased pooled analysis of 45 twin cohorts
(Nature Publishing Group, 2016-06-23)
Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking. We conducted an individual-based ...
