WebbWe cannot rely solely on findings from Cases study or other similar research, but at the very least we need to verify these animals’ findings with findings from human studies.There is difficulty determining the role of genetic factors in aggression. Firstly, more than one gene contributes to a given behaviour that and it can be a combination ... WebbAttempts have been made to deny or minimize the role of genes in human behavior, but the evidence for their role is overwhelming. We ... and Eibl-Eibesfeldt (1989). Physiological research on aggression—such as the roles of hormones, neuro transmitters, brain lesions, impulsiveness, and prenatal insults—is probably more familiar ...
WebbIndeed it seems that genetics, along with the environment, play multiple roles in determining psychological responses in humans and animals. Aggression is one psychosocial behavior in which the role of genetic influences and environmental influences are not exactly known. WebbThis suggests an interaction between genes and the environment, supporting a diathesis-stress explanation. Evaluation: It is hard to isolate the role of genes from environmental influences. Genes may only create a vulnerability to aggression, when combined with certain environmental influences.
WebbSome studies indicate that low-activity alleles specifically increase the risk of violence and aggression in individuals who were abused as children. Researchers are studying how these MAOA gene polymorphisms are involved in modulating behavior and the role of environmental factors, such as childhood abuse or situations in which a person is ...
