Transcript

  • 1. Aggression and Hurting
    The nature and nurture of aggression
  • 2. French Philosopher Jean-Jacques Rousseau (1712-1778) blames society, not human nature, for social evils.
    Jean-Jacques Rousseau
    Is Aggression an Instinct?
  • 3. English Philosopher Thomas Hobbes (1588-1679) sees society’s laws as necessary to restrain and control the human brute.
    Thomas Hobbes
    Is Aggression an Instinct?
  • 4. In the last century, “brutish” view—that aggressive drive is inborn and thus inevitable—was argued by Sigmund Freud and Konrad Lorenz.
    Inborn
    Is Aggression an Instinct?
    Instinctual
    Both agreed that that aggressive energy is instinctual (unlearned and universal)
    If not discharged, it builds up until it explodes
  • 5. Freud speculated that human aggression springs from a self-destructive impulse
    It redirects toward others the energy of a primitive death urge (death instinct)
    Sigmund Freud
    Is Aggression an Instinct?
  • 6. An animal behavior expert, he saw aggression as adaptive rather than self-destructive
    KonradLorenz
    Is Aggression an Instinct?
  • 7. Influences of Aggression
  • 8. Neural Influences
    Researchers have found neural systems in both animals and humans that facilitate aggression
    When scientists activate these areas in the brain, hostility increases; when they deactivated them, hostility decreases.
    The prefrontal cortex acts like an emergency brake on deeper brain areas involved in aggressive behavior.
  • 9. Neural Influences
    In one experiment, researchers placed an electrode in an aggression-inhibiting area of a domineering monkey’s brain. One small monkey, given the button that activated the electrode, learned to push it everytime the tyrant monkey became intimidating.
    In human, after a woman receives electrical stimulation in her amygdala (a part of the brain core), the woman became enraged and smashed her guitar against the wall.
  • 10. Genetic Influences
    Heredity influence the neural system’s sensitivity to aggressive cues.
    Animals can be bred for aggressive purposes, as in cock fighting; sometimes for research purposes
    Finish Psychologist KirstiLagerpetz (1979) took normal albino mice and bred the most aggressive ones together and the least aggressive ones. After repeating the procedure for 26 generations.
    Aggression varies among humans and primates (Asher, 1987; Olweus, 1979).
    Our temperaments are partly brought with us in the world, influenced by our sympathetic nervous system.
  • 11. Levels of various substances in the blood can provide clues to a patient's condition and aggression
    When people are provoked, alcohol unleashes aggression (Bushman, 1993; Bushman & Copper, 1990; Taylor & Chermack, 1993)
    Violent people are more likely to drink and to become aggressive when intoxicated (White & others, 1993)
    Aggressiveness also correlates with the males sex hormone, testosterone
    Testosterone levels are high among prisoners convicted of unprovoked violent crimes than of non-violent crimes (Dabbs, 1992; Dabbs & others, 1995, 1998)
    Blood Chemistry
  • 12. Psychological Influences
  • 13. Psychological Influences
    Frustration always leads to some form of aggression.
    The classic frustration-aggression theory (Dollard & others. 1989; Miller, 1941)
    • Frustration is anything (such as the malfunctioning vending machine) that blocks our attaining goal.
    • 14. It grows when our motivation to achieve a goal is very strong, when we expected gratification, and when the blocking is complete.
  • Operant Conditioning (B.F. Skinner)
    If after performing an aggressive act an animal or human receives a positive reinforcement (such as food or a toy), they are likely to repeat the behavior in order to gain more rewards.
    In this way, the aggressive act becomes positively associated with the reward, which encourages the further display of aggression.
    Psychological Influences
  • 15. Social Learning Theory/Observational Learning(Albert Bandura)
    Aggression is initially learned from social behavior and it is maintained by other conditions 
    Aggressive responses can also be acquired through social modeling or social reference.
    Everyday life exposes us to aggressive models in the family.
    Social environment outside the home provides models.
    Bandura (1979) contended that aggressive acts are motivated by a variety of aversive experiences—frustration, pain, insults.
    Psychological Influences
  • 16. Environmental Influences
  • 17. Painful Accidents
    Pain heightens aggressiveness in individuals.
    Leonard Berkowitz (1983, 1989, 1999) and his associates demonstrated aggressiveness by having students hold one hand in lukewarm water or painfully cold water.
    Those whose hands were submerged in the cold water reported feeling more irritable and more annoyed, and they were more willing to blast another person with unpleasant noise
    Berkowitz concluded that aversive stimulation rather than frustration is the basic trigger of hostile aggression.
  • 18. But any aversive event, whether dashed expectation, a personal insult, or physical pain, can incite an emotional outburst
    Even the torment of a depressed state increases the likelihood of hostile aggressive behavior
    Painful Accidents
  • 19. An uncomfortable environment heightens aggressive tendencies.
    Offensive odors, cigarette smoke, and air pollution have all been linked with aggressive behavior (Rotton & Frey, 1985)
    But heat is the most-studied environmental irritant.
    William Griffit (1970) found that compared to students who answered questionnaires in a room with a normal temperature, those who did so in an uncomfortable hot room reported feeling more tired and aggressive, and experienced more hostility.
    Follow-up experiments revealed that heat also triggers retaliative actions (Bell, 1980; Rule & others, 1987).
    Heat
  • 20. Being attacked or insulted by another is especially conducive to aggression.
    Experiments confirm that intentional attacks breed retaliatory attacks.
    Attacks
  • 21. The subjective feeling of not having enough space—is stressful
    Crammed in the back of the bus, trapped in a slow moving freeway traffic, or living three to a small room in a college dorm diminishes one’s sense of control (Baron & others, 1976; McNeel, 1980)
    The stress experienced by animals allowed to overpopulate a confirmed environment that heighten aggressiveness (Calhoun, 1962; Christina & others, 1960)
