Lecture 11 - Aggression Flashcards
Aggression
- Any behavior that is intended to inflict physical or psychological harm on an organism or object
- *Key aspects:
1. Requires intent
2. Incl phys/psych harm inflicted
Types of aggression
- Instrumental
2. Hostile
Instrumental aggression
Aggressive acts carried out to achieve a goal (to obtain material, psychological, or social benefits)
- Generally deliberative in nature
- Motivated by rewards or avoidance of punishment
- Behavioral principle of reinforcement
Hostile aggression
Aggressive behavior, stemming from anger, with the goal to injure or cause death
- Often impulsive and irrational
- May not be deliberated upon
Biological factors/ theories of aggression
- Physiological Theories (brain structures, hormones)
- Ethological Theories (instincts, genetic factors)
- Sociobiological Theories: Role of aggression in survival (sexual competition and resource competition)
External/social factors/theories of aggression
- Frustration-aggression theory
2. Social learning theories
Biology of aggression - influences
- Genetic
- Identical twins have more similar aggressive tendencies than fraternal twins - Hormonal
- testosterone - Brain
- Amygdala
- Hypothalamus
Frustration-aggression hypothesis
According to this hypothesis, frustration leads to aggression
- Frustration always elicits aggression
- Every act of (hostile) aggression could be traced to an act of frustration
- Aggression causes catharsis, a reduction in the aggressive drive
Displaced aggression
Aggression against a safe, lower power target rather than the source of frustration
Social learning theory of aggression
- People are not born with a repertoire of aggressive responses
- People learn aggressive responses through experience or observation of others
E.g., Bobo Doll Studies
Social factors that increase aggression
- Frustration (can lead to increased aggression)
- Heat
- Alcohol
- Aggressive Cues
- Media Violence
- Video Games
General Affective Aggression Model (GAAM)
Repeated violent video game playing leads to: aggressive beliefs and attitudes, aggressive perceptions and expectations, aggressive desensitization, and to an increase in aggressive behavior
Why do violent video games increase aggression?
- Social learning
- Formation of aggressive schemas
- May form an automatic association between the self and aggression
Uhlmann and Swanson, 2004 - video games and aggression
- Playing violent video games causes the self to be associated with aggression (at least temporarily)
- Also found a relationship between IAT scores and long-term exposure to violent video games (r = 0.28)
- Suggests the effect of violent games on the implicit self-concept may be long-lasting
