Gustavson, Daniel E.; Friedman, Naomi P.; Stallings, Michael C.; Reynolds, Chandra A.; Coon, Hilary; Corley, Robin P.; Hewitt, John K.; Gordon, Reyna L. – Developmental Psychology, 2021
Individual differences in music traits are heritable and correlated with the development of cognitive and communication skills, but little is known about whether diverse modes of music engagement (e.g., playing instruments vs. singing) reflect similar underlying genetic/environmental influences. Moreover, the biological etiology underlying the…

Saunders, Gretchen R. B.; Liu, Mengzhen; Vrieze, Scott; McGue, Matt; Iacono, William G. – Developmental Psychology, 2021
Parent-child similarity is a function of genetic and environmental transmission. In addition, genetic effects not transmitted to offspring may drive parental behavior, thereby affecting the rearing environment of the child. Measuring genetic proclivity directly, through polygenic risk scores (PRSs), provides a way to test for the effect of…

Lecarie, Emma K.; Doane, Leah D.; Stroud, Catherine B.; Walter, Devan; Davis, Mary C.; Grimm, Kevin J.; Lemery-Chalfant, Kathryn – Developmental Psychology, 2022
Early life stress, daily life experiences, and the stress responsive hypothalamic-pituitary-adrenal (HPA) axis have each been examined as predictors of the development of psychopathology. Rarely have researchers attempted to understand the covariation or interaction among these stress domains using a longitudinal design in the prediction of…

Talbott, Elizabeth; Zurheide, Jaime L.; Karabatsos, George; Kumm, Skip – Behavioral Disorders, 2021
Valid and reliable teacher ratings serve as the foundation for screening and assessment of youth with behavioral disorders and twin studies offer an opportunity to study those ratings. We conducted a meta-analysis of 15 empirical investigations of aggressive and rule-breaking behavior using teacher ratings in the context of a twin research design.…

Vitaro, Frank; Beaver, Kevin M.; Brendgen, Mara; Dickson, Daniel J.; Dionne, Ginette; Boivin, Michel – Developmental Psychology, 2021
The goal of the present study was to replicate Burt et al. (2009) and Hou et al. (2013) findings by determining the contribution of peers' deviance to changes in participants' (monozygotic [MZ] twins') self-reported delinquency from mid- to late adolescence while controlling for possible gene-environment correlations (rGE) through the use of the…

Sofieke T. Kevenaar; Elsje van Bergen; Albertine J. Oldehinkel; Dorret I. Boomsma; Conor V. Dolan – npj Science of Learning, 2023
The non-cognitive skills self-control and grit are often considered predictors of school performance, but whether this relationship is causal remains unclear. We investigated the causality of this association using a twin design. Specifically, we evaluated the direct impact of self-control and grit on school performance, while controlling for…

Neufeld, Janina; Taylor, Mark J.; Lundin Remnélius, Karl; Isaksson, Johan; Lichtenstein, Paul; Bölte, Sven – Autism: The International Journal of Research and Practice, 2021
Autism spectrum disorder is associated with sensory processing alterations, such as sensory hyper- and hypo-responsiveness. Twin studies are scarce in this field, but they are necessary in order to disentangle the genetic and environmental contributions to this association. Furthermore, it is unclear how different neurodevelopmental/psychiatric…

Morneau-Vaillancourt, Geneviève; Matte-Gagné, Célia; Cheesman, Rosa; Brendgen, Mara; Vitaro, Frank; Tremblay, Richard; Dionne, Ginette; Boivin, Michel – Developmental Psychology, 2021
The present study examined, within a longitudinal family-informed design and across middle childhood, the predictive associations between preference for solitude and social wariness, two forms of social withdrawal, and peer difficulties. Specifically, preference for solitude, rather than social wariness, was expected to predict peer victimization…
