Aggression and Hurting (Social Psychology)

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