3. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Chapter Outline I. What Is Aggression?

4. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? An aggressive action is intentional behavior aimed at causing either physical or psychological pain.

5. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Hostile aggression is an act of aggression stemming from feelings of anger and aimed at inflicting pain.

6. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Instrumental aggression is aggression that serves as a means to some goal other than causing pain.

7. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Is Aggression Inborn, or Learned? Scientists do not agree on whether aggression is innate or learned. The debate has been raging for centuries.

8. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Is Aggression Inborn, or Learned? Freud postulated that humans have innate instincts toward life, Eros, and towards death and aggression, Thanatos.

9. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Is Aggression Instinctual? Situational? Optional? Even in the most aggression-prone species, aggression is an optional strategy and is determined by the organism’s previous social experiences and by the specific social context in which the organism finds itself.

10. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Aggressiveness and Culture Berkowitz (1993) suggests that humans seem to have an inborn tendency to respond to certain provocative stimuli by striking out against the perpetrator.

11. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Aggressiveness and Culture Whether or not this aggressive action is expressed depends on the interaction of these innate propensities with learned inhibitory responses and the nature of the social situation.

12. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Aggressiveness and Culture In humans, innate patterns of behavior are infinitely malleable; thus, cultures vary widely in the degree of aggressiveness.

13. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. What Is Aggression? Aggressiveness and Culture The evidence is inconclusive on whether or not aggression has an instinctual component, but it is clear that aggression can be modified by situational factors. Two examples of this are aggression among the Iroquois and the regional differences in aggressive behavior in the United States.

14. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Chapter Outline II. Neural and Chemical Influences on Aggression

15. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Neural and Chemical Influences on Aggression Neural and Chemical Influences on Aggression The amygdala is an area in the core of the brain associated with aggressive behavior. But even if the amygdala is directly stimulated, whether or not the organism will aggress depends on situational factors.

16. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Neural and Chemical Influences on Aggression Serotonin and Testosterone Serotonin is a chemical in the brain that may inhibit aggressive impulses. Testosterone is a male sex hormone associated with aggression. A wide variety of studies have shown that men are more aggressive than women are. However, the research on gender differences is complex and results depend on situational and cultural factors.

17. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Neural and Chemical Influences on Aggression Alcohol and Aggression Alcohol serves as a disinhibitor and leads people to be more likely to commit actions frowned upon by society; thus alcohol can foster aggression when people are provoked.

18. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Neural and Chemical Influences on Aggression Pain, Discomfort, and Aggression Both animal and human studies show that pain will increase the probability that an organism will aggress. Other forms of bodily discomfort (heat, humidity, air pollution, offensive odors) may also act to lower the threshold for aggressive behaviors.

19. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Chapter Outline III. Social Situations and Aggression

20. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Frustration and Aggression Frustration-aggression theory says that frustration, the perception that you are being prevented from obtaining a goal, will increase the probability of an aggressive response.

21. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Social Situations and Aggression Frustration and Aggression The closer someone is to a goal, the greater the frustration when one is thwarted and the higher the probability that the person will act aggressively.

22. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Frustration and Aggression Aggression also increases when frustration is unexpected. The perception of relative deprivation, feeling that one has less than one deserves or has been led to expect or has less than similar people, can increase aggressive behavior.

23. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Being Provoked and Reciprocating People usually feel the need to reciprocate after they are provoked by aggressive behavior from another person.

24. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Being Provoked and Reciprocating If we think the provocation was unintentional, we are unlikely to reciprocate. And if there are mitigating circumstances, we may not aggress, so long as the circumstances are known at the time of the aggression.

25. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Aggressive Objects as Cues An aggressive stimulus is an object that is associated with aggressive responses (for example, a gun), and whose mere presence can increase the probability of aggression.

26. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Aggressive Objects as Cues

27. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Imitation and Aggression A major cause of aggression is social learning. Bandura and associates (1961) demonstrated social learning theory, the theory that we learn social behavior (for example, aggression) by observing others and imitating them.

28. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violence in the Media: TV, Movies, and Video Games A number of long-term studies indicate that the more violence individuals watch on TV as children, the more violence they exhibit years later as teens and adults.

29. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violence in the Media: TV, Movies, and Video Games

30. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violence in the Media: TV, Movies, and Video Games Adults as well as children are influenced by violent television.

31. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violence in the Media: TV, Movies, and Video Games Repeated exposure to horrifying events has a numbing effect on our sensitivity to those events.

32. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violence in the Media: TV, Movies, and Video Games Adolescents and adults who watch more than four hours of television per day are more likely than people who watch less television to have an exaggerated view of the level of violence that occurs outside their home and they have a greater fear of being personally assaulted.

33. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violence in the Media: TV, Movies, and Video Games At least five reactions to media violence help explain why exposure to violence in the media might increase aggression: “If they can do it, so can I.”, “Oh, so that’s how you do it!”, “I think it must be aggressive feelings that I’m experiencing.”, “Ho-hum, another brutal beating; what’s on the other channel?”, and “I had better get him before he gets me!”

34. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Does Violence Sell?

35. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violent Pornography and Violence Against Women During the past three decades, almost half of all rapes or attempted rapes are attributed to date rape. Scripts are ways of behaving socially that we learn implicitly from our culture. The sexual scripts adolescents are exposed to suggest that females should resist males’ sexual advances and that males should be persistent.

36. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violent Pornography and Violence Against Women There has been an increase in the availability of magazines, films, and videos depicting vivid, explicit sexual behavior.

37. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Social Situations and Aggression Violent Pornography and Violence Against Women However, experimental evidence regarding the effects of pornography on violence against women is very complex. One conclusion that can be made is that violent sexual pornography presents a clear problem for our society and it increases aggression against women.

38. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Chapter Outline IV. How to Reduce Aggression

39. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Does Punishing Aggression Reduce Aggressive Behavior? For children, harsh punishment provides a model of aggression and does not prevent a child from engaging in the forbidden behavior when the child is unsupervised.

40. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Does Punishing Aggression Reduce Aggressive Behavior? The threat of mild punishment, swiftly administered, does, however, seem to reduce aggression. The combination of education and mild punishment has been successful in efforts to reduce the occurrence of bullying behavior.

41. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Does Punishing Aggression Reduce Aggressive Behavior? For adults, the research evidence is mixed. Laboratory experiments suggest that under ideal circumstances punishment can reduce aggression. But in real life, punishment occurs under anything but ideal conditions.

42. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Does Punishing Aggression Reduce Aggressive Behavior? Berkowitz (1993) suggests that it is the swiftness and certainty of punishment rather than its severity that is important in leading to reductions in aggression.

43. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Does Punishing Aggression Reduce Aggressive Behavior?

44. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Catharsis and Aggression The common belief that one can “blow off steam” and “get it out of your system” is an oversimplification of Freud’s psychoanalytic notion of catharsis.

45. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Catharsis and Aggression According to this idea, performing an aggressive act relieves built-up aggressive energies and hence reduces the likelihood of further aggressive behavior.

46. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Catharsis and Aggression However, controlled studies suggest that attempting to reduce one’s anger by acting violently increases, rather than decreases, subsequent aggression and hostility.

47. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Catharsis and Aggression Research has found that when people are allowed to express their aggression, they later feel greater dislike and hostility toward their victims.

48. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression Catharsis and Aggression This effect is magnified when a nation is at war. Being at war weakens the population’s inhibitions against aggression, leads to imitation of aggression, makes aggressive responses more acceptable, and numbs people and makes them unsympathetic toward the victims. Also, war legitimizes the use of violent solutions to address difficult problems.

50. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression What Are We Supposed to Do with Our Anger? There is an important difference between being angry and expressing that anger in a violent and destructive manner. Expressing anger nonviolently is an assertive response that avoids the dangers of either violent expression or of repression of the feelings.

51. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression What Are We Supposed to Do with Our Anger? One way to reduce aggression in another person is for the person who caused the frustration to take responsibility, apologize, and indicate it won’t happen again.

52. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression What Are We Supposed to Do with Our Anger? Children exposed to models who behave nonaggressively when provoked show a much lower frequency of aggression than children who were not exposed to these models.

53. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression What Are We Supposed to Do with Our Anger? In most societies it is the people who lack proper social skills who are most prone to violent solutions to interpersonal problems.

54. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression What Are We Supposed to Do with Our Anger? Thus one way to reduce violence is to teach people how to communicate anger and criticism constructively and how to negotiate and compromise.

55. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. How To Reduce Aggression What Are We Supposed to Do with Our Anger? Building empathy, for example by teaching empathy in school, not only reduces aggressiveness but also can increase self- esteem, generosity, and positive attitudes.

56. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Chapter Outline V. Could the Columbine Massacre Have Been Prevented?

57. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Could the Columbine Massacre Have Been Prevented? Aronson (2000) suggests that although the violent acts of the Columbine massacre were pathological, it would be a mistake to dismiss them as just the result of individual pathology.

58. Aronson Social Psychology, 5/e Copyright © 2005 by Prentice-Hall, Inc. Could the Columbine Massacre Have Been Prevented? What is necessary to acknowledge is the social situation that children and adolescents face in schools. Thus, making our schools safer by changing the negative, exclusionary social atmosphere may help reduce the frequency of violence in schools.
