"The general aggression model also explains that exposure to videogame violence can increase aggressive behavior both in the short and long term by noting that aggression is largely based on existing knowledge structures or existing mental scripts that are created by the process of social learning (Anderson et al., 2004). That is, individuals can learn new skills and information by watching the behaviors of others, especially if those behaviors are rewarded, performed by attractive actors, or do not cause pain or suffering fort the victim of aggression (i.e., sanitized violence). In the short term, both personological and situational input variables can lead to aggressive behavior. Personological variables include personality variables such as aggressive disposition, current states, beliefs, attitudes, and so on. Situational variables are found in the environment surrounding the person and include factors such as aggressive cues (e.g., playing a violent videogame), being provoked, or feeling pain. Both of these inputs can impact the present internal state of the person. For example, aggression may become more likely if an individual has an aggressive disposition and also plays an aggressive videogame. This may lead to feelings of hostility. Then, given the opportunity to retaliate against someone who has insulted the person, for example, that individual may behave more aggressively than someone without those personological or situational factors in place."
