Aggression/Molecular Genetics: for literature examining genetic contributions to the development of aggression and how genetic and environmental factors interact to confer risk see Beisky & Pluess, 2009(1); Dick et al., 2006)(2). >Aggression/Bandura, >Aggression/Developmental psychology, >Bobo doll study/Bandura.
Bandura: In assigning participants to control and experimental groups in the Bobo doll study, Bandura et al.(3) recognized that children initially predisposed to aggressive behavior might be more susceptible to imitating novel aggressive behaviors than children not predisposed to aggressive behavior would be and therefore matched children on levels of aggression before randomly assigning them to a control or experimental group.
There is now empirical evidence that particular genes confer risk for the development of aggressive behavior, but this genetic risk can be moderated by environmental factors (Caspi et al., 2002(4); Dodge, 2009(5)).
For example, variants of the CHRM2 gene are differentially associated with trajectories of externalizing behavior (including aggression), but links between the risky variant of CHRM2 and externalizing are exacerbated for adolescents who affiliate with deviant peers (Latendresse et al., 2011)(6). Dick et al. (2009)(7) demonstrated that adolescents carrying a risky GABRA2 genotype were likely to have persistently high levels of externalizing behavior from early adolescence into adulthood; however GABRA2 genotype interacted with parental monitoring such that the link between GABRA2 and high externalizing behavior was weakened by high levels of parental monitoring.
