This chapter explores the complex relationship between exposure to media violence, aggression, and desensitization across various effects dimensions, from physiological and cognitive to affective and behavioral. The impact of contextual factors of media violence is explored, supported by a discussion of Leone's work on “ratings creep.” Susceptibility to media violence is also discussed, informed by Paradise's videogame research dealing with trait aggression and playing style. The authors conclude that the relationship between exposure to media violence, aggression, and desensitization is not linear. Short-term increases in responsiveness to violent media – suggesting aggression-causing effects – can cede to decreased responses – indicative of a desensitization effect – over time. It is this pattern, the authors assert, that is most likely to guide future research into these phenomena.
