“…Aggression can be defined as any behavior intended to cause harm in others motivated either reactively, thus occurring as a response to a perceived threat, or instrumentally/proactively ( Anderson and Bushman, 2002 ). Increasing evidence points to the rewarding and thus self-perpetuating nature of aggression ( Nell, 2006 ; Elbert et al, 2010 , 2018 ; Koebach and Elbert, 2015 ; Golden and Shaham, 2018 ; Golden et al, 2019 ; Koebach et al, 2021 ). In recent aggression models, aggressive behavior is described as a consequence of situational (e.g., stress, frustration, discomfort, threatening stimuli) and personal factors (e.g., traits, attitudes, gender, trauma history), as well as internal states (e.g., cognition, affect, and arousal; e.g., Anderson and Bushman, 2002 ; Bushman, 2016 ; Elbert et al, 2018 ).…”
