LECTURE 4: MEDIA PSYCHOLOGY Wayne Warburton 1 2 Social Psychology The General Aggression Model • Aggression elicited by the situation rather than the personality • Social cognition • Schemas, scripts, knowledge structures • Automaticity, priming • Learned social behaviours • Triggers and cues • Models from this sub-discipline usually start with a person-situation interaction • The General Aggression Model is a good example 3 • Craig Anderson and Brad Bushman have put together a model that incorporates a range of theories, approaches and research findings into a General Aggression Model (GAM). • In this theory, an episode of aggression firstly depends on the nature of the situation (the aspects of the situation that can trigger aggression) and what the person brings to it (the beliefs, personality factors, memories etc. that increase their readiness to aggress in that situation). 4 The General Aggression Model Craig Anderson, Brad Bushman • Whether or not someone responds to a situation with aggression depends firstly on the nature of the thoughts, feelings and physiological responses thata are aroused, This material is provided to you as and then on how much that person thinks Macquarie through University theirstudent responsefor your individual research and study purposes only.

Violent video games have measurable and statistically significant effects on both males and females. Theoretically important effects of violent video games have been confirmed by many empirical studies. The effects have been replicated by researchers in different settings and in numerous countries. The psychological processes underlying such effects are well understood and include: imitation, observational learning, priming of cognitive, emotional and behavioral scripts, physiological arousal, and emotional desensitization.

Aggressive Behavior, 38, 335-341. These are general processes that underlie all types of social behavior, not just aggression and violence; they have been confirmed by countless studies outside of the media violence domain. In addition to causing an increase in the likelihood of aggressive behavior, violent video games have also been found to increase aggressive thinking, aggressive feelings, physiological desensitization to violence, and to decrease pro-social behavior.” (Anderson, Bartholow, Berkowitz, Brockmeyer, Bushman, Dill, Donnerstein, Gentile, Huesmann, Krahe, Moller, Sakamoto & Warburton, 2010) 19 http://www.israsociety.com/news.html#MVReport 20 Well researched effects of violent media • Both short term and long term effects • Increases in aggressive thoughts, Other effects of violent media • Subtle long-term changes to thinking: • Hostile attributional bias • Increase in normative beliefs approving feelings and behaviour • More fearful aggression • Overestimate likelihood of being a victim • Age dependent • Emotional desensitisation to violence • Less concerned about others’ suffering • Tolerate increasing levels of violence in the • Aggressive problem solving scripts for behaviour • Decreased empathy • Decreased prosocial behaviour world around them 21 22 Anderson Warburton et al 2017 7 nation study (PSPB) HOWEVER: A risk factor approach • Violent and fairly aggressive behaviour always has multiple contributing risk factors • These may include personality traits, type of This material is provided to you as a Macquarie University student for your individual research and study purposes only.
