Although aggression can be beneficial in certain situations (e.g. playing sports, self-defense), excessive and inappropriate aggression can lead to adverse physical and psychological health outcomes in both perpetrators and victims. Genetic susceptibility to negative environments can increase the likelihood of aggressive behavior in the context of situational risk factors. Low efficiency of serotonin neurotransmission and exposure to stress appear to play a prominent role in the etiology of aggressive behavior. A set of three studies assessed the contribution of polygenic risk (TPH2 rs4570625, SLC6A4 5-HTTLPR+rs25531, HTR1B rs13212041, MAOA uVNTR) to aggressive behavior, including alcohol-related aggression, in university students at varying …

Exposure to images of nature following a stressful event can reduce physiological measures associated with stress. The objectives of this study was to determine whether exposure to nature before the stressor can buffer the stress response. We varied whether nature or urban images were viewed before or after a stressor and measured galvanic skin response in our participants. We describe how order of presenting the stressor influences nature’s calming effect on physiology.
