Situational determinants
Aggression as a response to an aversive event (including frustration)
Social-Learning Theories of Aggression
Aggression as a learned social behavior
Frustration
Experienced when something prevents us from reaching our goals
Weapons Effect
Increase in likelihood of aggression when weapons are present
Berkowitz & LePage
Creative task, coming up with ideas – another participant (actually a
confederate) gives you 1 shock (if ideas good) or 7 shocks (if ideas bad)
(number of shocks actually randomly determined)
• Then partners switch and participant delivers shocks to “partner”
• Next to “shock machine:” nothing, badminton props, or two guns
Yes
Stronger shocks in a presence of a weapon?
Desensitization
Making people less responsive to violence (and less empathic)
Social script
Expectations of how to act in various situations
Altered perceptions
• Of what happens in the real world
• Even your definition of aggression may change
Cognitive priming
Of aggression-related ideas (making them more accessible
Catharsis hypothesis
Playing violent video games allows people to release anger and to safely
express their aggressive tendencies
• NOT supported by research
Anderson meta-analysis
violent game playing increased aggression
Risk factors for extreme violence
who experience depression and/or social rejection, who
immerse in violent video games, who have access to firearms do NOT
engage in extreme violence
Third variables and reverse causation
correlational studies drawback
Stereotypes are

The tendency for people to assume that within-group similarity is much stronger for outgroups than for ingroups.
Own-race identification bias
The tendency for people to be better able to recognize and distinguish faces from their own race
than from other races.
Contact hypothesis
contact between members of different groups can reduce intergroup hostility, especially if the contact involves one-on-one interactions between individuals of equal status, if it encourages the cooperative pursuit of superordinate goals, and if it is supported by the prevailing norms in each group.
