The study was conducted by researchers from the University of Quebec at Montreal, Laval University, the University of Alabama, the University of Montreal, and University College Dublin.
"Aggressive behavior in middle childhood is at least partly explained by genetic factors, but genetic influences on behavior usually don't operate independently of environmental influences," notes Mara Brendgen, professor of psychology at the University of Quebec at Montreal, who led the study.
Researchers studied 217 Canadian identical and fraternal twin pairs at age 7 to delve into the interplay between nature and nurture involving the source of aggression in the children. Twin pairs weren't in the same classrooms, but had different teachers and different classmates. Classmates rated the twins' level of aggressive behavior and the extent to which they were victimized by peers. The twins' teachers rated the quality of their relationship with each twin. Genetic effects on aggression were estimated by comparing the similarity in behaviors of identical and fraternal twin pairs.
The study found that children who were genetically vulnerable to being aggressive were more likely to be victimized by their classmates than others. However, these children were protected from acting aggressively and being the target of other children's aggression if they had a very good relationship with their teacher—a relationship that was warm and affectionate and involved open communication.
"Children's relationships with teachers and with peers in school play a critical role in shaping their social-behavioral development," notes Brendgen. "Our study found that a good relationship with the teacher can protect genetically vulnerable children from being aggressive and, in consequence, from becoming the target of other children's aggressive behavior."
The findings can inform interventions aimed at addressing children's aggression, and can also be used in teacher-training efforts.
The study was supported by the Social Sciences and Humanities Research Council of Canada, the Fonds Concerté pour l'Aide à la Recherche, the Fonds Québécois de la Recherche sur la Société et la Culture, the Canadian Institutes of Health Research, and the Fonds de Recherche en Santé du Québec.

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
