lecture 6 - agression Flashcards
two types of aggression
-hostile aggression
-instrumental aggression
hostile agression
-is motivated by anger and hostility, and has the primary aim of harming others, either physically or psychologically
instrumental aggression
-is behaviour intended to harm others in order to achieve a goal
eg attracting attention, acquiring wealth, or advancing political or ideological causes
-many acts of aggression involve a mix of hostile and instrumental motives
situational determinants of aggression
Aggression is not solely caused by aggressive people, but rather by certain situational factors that can release people’s aggressive tendencies.
-hot temp
-violence/media violence
-rejection violence
-income inequality
situational determinants of aggression,
-hot weather
-hot weather affects levels of aggressive behaviour and violence.
-hotter cities have higher rates of violent crime, and more violence occurs during hot months than during cool months (andeson 1987,1989)
-temp above 32c are a strong predictor of elevated violent crime rates
-as earths temperature rises , we might expect to see increases in _____ throughout the world
-whats an explanation for this
-violence
-one explanation for this is that the heat can cause arousal which people may attribute to other people or circumstances, leading to misplaced anger and aggression
situational determinants of aggression,
-media violence
The average American child watches 3-4 hours of television a day, and about 90% of those programs portray some form of violence (Gerbner et al.,1986).
Media violence has been shown to promote aggressive acts in real life. When a highly publicised suicide occurs, copycat suicides follow.
People tend to be more aggressive, after seeing films in which they identify with the perpetrator of the violent act (Leyens & Picus, 1973
can watching violence on tv predict future violence of children
Children who watch violence on TV tend to commit serious crimes asadults, compared to kids who don’t(Leyens et al., 1975)
situational determinants of aggression,
-media violence
limitations
Measures of aggression not necessarily relating to real-world violence
-Long or short lasting effects?
Playing violent video games can also lead to more aggressive behaviour in the short run.85% of American teenagers play video games regularly (Anderson &Bushman, 2001).
The average American between the ages of 8 and 18 spends about 13hours a week playing video games, with boys spending more time (just over 16 hours) on average than girls(about 9 hours, Gentile, 2009)
Constant attention to video games can create conflicts within families and may even lead to addiction. A famous example of individuals who were heavily influenced by violent video games are Eric Harris and Dylan Klebold, who committed the Columbine High School shooting in1999.
playing violent video games correlates with
1) increase aggressive behaviour
2) reduce prosocial behaviour, such as helping or altruism
3) increase aggressive thoughts and emotions, especially anger
4) increase blood pressure and heart rate, physiological responses associated with fighting
situational determinants of aggression,
-social rejection and isolation
social rejection and isolation are powerful triggers of aggressive tendencies
e.g., Harris and Klebold were rejected by popular students. The U.S. Department of Education report that school shooters tend to feel rejected by their peers.
However, it is clear that social rejection alone was not a sufficient cause of the behaviour and underlying pathologies of the shooters were also a factor.
why does social rejection lead to aggressive tendencies
Geoff MacDonald and Mark Leary(2005) proposed that throughout human evolution, being socially rejected from the group was akin to a death warrant given our dependence on others for survival, which led to the activation of a threat defence system that includes feelings of distress and pain, and defensive aggressive tendencies.
Social cues such as hearing someone’s gossip or seeing a sneer can also trigger this threat defence system
social rejection can lead to ________ in romantic relationships
Studies have shown that social rejection can lead to feelings of distress, shame, self-doubt, and a submissive posture, and also increases the likelihood of aggression in romantic relationships and physical abuse (Williams, 2007).
-the brain region that processes physical pain lights up when experiencing _____…
Research has also shown that the brain region that processes physical pain also lights up when experiencing social pain, and that common painkillers can also diminish social pain (DeWall et al., 2010)
situational determinants of aggression
income inequality
income inequality at the level of nation, state, county, and neighbourhood strongly predicts aggression of just about every kind.
Children in countries with greater income inequality are also more likely to experience conflict with their peers and to report being victims of bullying
