Aggression
behaviour that is
intended to harm another individua
Anger
consists of strong feelings of
displeasure in response to a perceived
injury.
Hostility
negative, antagonistic attitude
toward another person or group.
Violence
extreme acts of
aggression
Instrumental/pro-active Aggression
Harm is inflicted as a means to a desired end
Emotional/reactive Aggression
Harm is inflicted for its own sake (in reaction to something)
Culture and Aggression
• Aggression varies dramatically between cultures – The forms violence typically takes – People’s attitudes toward various kinds of aggression
Individual differences which predict aggression
- Low agreeableness
- Low openness
- High neuroticism
- Traits
overt agression (and gender)
more men
relational aggression (and gender)
more women
evolutionary perspective and aggression gender
Why gender differences?
– Males aggress to achieve and maintain
status.
– Females aggress to protect offspring.
biological factors and aggression (3)
- Genetics
Mixed overall results on heritability
of aggression
– Trend in research supports heritability of
human aggressiveness to at least some
degree - ○ MAOA gene linked to aggressive behaviour
• Serotonin ○ Low levels linked to aggression • Brain & EF ○ Abnormalities in PFC ○ Poor EF
biological differences in gender based aggression
• Testosterone
○ Association between testosterone and aggression
○ Especially if low in cortisol
social learning theory of aggression
○ The theory that behaviour is learned through the observation of others as well as through the direct experience of rewards and punishments
○ Bobo dolls
○ Those perpetrating violence have often witnessed violence
socialisation and gender differences in aggression
§ Overt aggression more acceptable amongst boys
§ Using relational aggression can allow a girl access to benefits
§ Culture of honor (males) - culture
□ Emphasising honor and social status - role of aggression
□ Promotes violent behaviour
socialisation and cultural differences in aggression
Socialization of aggression also varies from culture to culture. For example, Giovanna Tomada and Barry Schneider (1997) report that adolescent boys in traditional villages in Italy are encouraged to aggress as an indication of their sexual prowess
frustration-aggression hypothesis
- Frustration - which is produced by interrupting a person’s progress towards an expected goal - will always elicit the motive to aggress
- All aggression is caused by frustration
displacement
○ Aggressing against a substitute target because aggressive acts against the source are inhibited by fear or lack of access
catharsis
○ Reduction of the motive to aggress said to result from imagined, observed or actual act of aggression
problems with frustration-aggression hypothesis
○ Carthasis can inflame aggression
frustration-aggression hyp revised (Berkowitz, 1989)
Frustration is but one of many unpleasant
experiences that can lead to aggression
by creating negative, uncomfortable
feelings.
• It is the negative feelings (negative affect),
not frustration itself, that can trigger
aggression.
role of affect in aggression and situational factors
• Heat - increases negative affect = aggression
• Provocation
○ Social rejection
Positive Affect
• Research shows that inducing a pleasant mood can reduce aggression
arousal and aggression and situational factors
• Excitation transfer
○ Arousal created by one stimulus can intensify another response
○ Physical exercise - increase in aggression/violence
• Heat increases arousal
cognition and aggression and situational factors
Both automatic and deliberate thoughts
play a critical role in aggression
Automatic cognitions
– Weapons effect – tendency that the likelihood
of aggression will increase by mere presence
of guns
Higher order cognitions:
○ Angry person restrains self from aggressing because costs are too high
- rumination: thinking about aggressive thoughts over and over
