When one animal attacks another, it engages in the most obvious example of aggressivebehavior. Psychologists have adopted veral approaches to understanding aggressivebehavior in people.
The Biological Approach. Numerous biological structures and chemicals appear to be involved inaggression. One is the hypothalamus, a region of the brain. In respon to certain stimuli,many animals show instinctive aggressive reactions. The hypothalamus appears to beinvolved in this inborn reaction pattern: electrical stimulation of part of the hypothalamustriggers stereotypical aggressive behaviors in many animals. In people, however, who brainsare more complex, other brain structures apparently moderate possible instincts.
An offshoot of the biological approach called sociobiology suggests that aggression is naturaland even desirable for people. Sociobiology views much social behavior, including aggressivebehavior, as genetically determined. Consider Darwin's theory of evolution. Darwin held thatmany more individuals are produced than can find food and survive into adulthood. A strugglefor survival follows. Tho individuals who posss characteristics that provide them with anadvantage in the struggle for existence are more likely to survive and contribute their genesto the next generation. In many species, such characteristics include aggressiveness. Becauaggressive individuals are more likely to survive and reproduce, whatever genes are linked toaggressive behavior are more likely to be transmitted to subquent generations.

The sociobiology view has been attacked on numerous grounds. One is that people's capacityto outwit other species, not their aggressiveness, appears to be the dominant factor inhuman survival. Another is that there is too much variation among people to believe that theyare dominated by, or at the mercy of, aggressive impuls.党支部成立条件

The Psychodynamic Approach. Theorists adopting the psychodynamic approach hold that innerconflicts are crucial for understanding human behavior, including aggression. Sigmund Freud,for example, believed that aggressive impuls are inevitable reactions to the frustrations ofdaily life. Children normally desire to vent aggressive impuls on other people, including theirparents, becau even the most attentive parents cannot gratify all of their demandsimmediately. Yet children, also fearing their parents' punishment and the loss of parental love,come to repress most aggressive impuls. The Freudian perspective, in a n: es us as"steam engines." By holding in rather than venting "steam," we t the stage for futureexplosions. Pent-up aggressive impuls demand outlets. They may be expresd towardparents in indirect ways such as destroying furniture, or they may be expresd towardstrangers later in life.
According to psychodynamic theory, the best ways to prevent harmful aggression may be toencourage less harmful aggression. In the steam-engine analogy, verbal aggression mayvent some of the aggressive steam. So might cheering on one's favorite sports team.Psychoanalysts, therapists adopting a psychodynamic approach, refer to the ventin
g ofaggressive impuls as "catharsis." Catharsis is theorized to be a safety valve. But rearchfindings on the ufulness of catharsis are mixed. Some studies suggest that catharsis leadsto reductions in tension and a lowered likelihood of future aggression. Other studies,however, suggest that letting some steam escape actually encourages more aggression lateron.钢锅
The Cognitive Approach. Cognitive psychologists asrt that our behavior is influenced by ourvalues, by the ways in which we interpret our situations and by choice. For example, peoplewho believe that aggression is necessary and justified-as during wartime-are likely to actaggressively, whereas people who believe that a particular war or act of aggression is unjust,or who think that aggression is never justified, are less likely to behave aggressively.
One cognitive theory suggests that aggravating and painful events trigger unpleasantfeelings. The feelings, in turn, can lead to aggressive action, but not automatically.Cognitive factors intervene. People decide whether they will act aggressivel
y or not on thebasis of factors such as their experiences with aggression and their interpretation of otherpeople's motives. Supporting evidence comes from rearch showing that aggressive peopleoften distort other people's motives. For example, they assume that other people mean themharm when they do not.
Catharsis: In psychodynamic theory, the purging of strong emotions or the relieving oftensions.
Paragraph 2: The Biological Approach. Numerous biological structures and chemicals appear tobe involved in aggression. One is the hypothalamus, a region of the brain. In respon tocertain stimuli, many animals show instinctive aggressive reactions. The hypothalamusappears to be involved in this inborn reaction pattern: electrical stimulation of part of thehypothalamus triggers stereotypical aggressive behaviors in many animals. In people, however,who brains are more complex, other brain structures apparently moderate possibleinstincts.
