     Researchers in the psychology department at the University of California at Los Angeles (UCLA)

have discovered a major difference in the way men and women respond to stress. This difference may

explain why men are more likely to suffer from stress-related disorders.

     Until now, psychological research has maintained that both men and women have the same

"fight-or-flight" reaction to stress. In other words, individuals either react with aggressive behavior, such

as verbal or physical conflict ("fight"), or they react by withdrawing from the stressful situation ("flight").

However, the UCLA research team found that men and women have quite different biological and

behavioral responses to stress. While men often react to stress in the fight-or-flight response, women

often have another kind of reaction which could be called "tend and befriend." That is, they often react

to stressful conditions by protecting and nurturing their young ("tend"), and by looking for social contact

and support from others - especially other females ('befriend").

     Scientists have long known that in the fight-or- flight reaction to stress, an important role is played by

certain hormones(激素) released by the body. The UCLA research team suggests that the female

tend-or-befriend response is also based on a hormone. This hormone, called oxytocin, has been studied

in the context of childbirth, but now it is being studied for its role in the response of both men and women

to stress. The principal investigator, Dr. Shelley E. Taylor, explained that "animals and people with high

levels of oxytocin are calmer, more relaxed, more  social, and less anxious." While men also secrete(分

泌)oxytocin, its effects are reduced by male hormones.

     In terms of everyday behavior, the UCLA study found that women are far more likely than men to

seek social contact when they are feeling stressed. They may phone relatives or friends, or ask directions

if they are lost.

     The study also showed how fathers and mothers responded differently when they came home to their

family after a stressful day at work. The typical father wanted to be left alone to enjoy some peace and

quiet. For a typical mother, coping with a bad day at work meant focusing her attention on her children

and their needs.

     The differences in responding to stress may explain the fact that women have lower frequency of

stress-related disorders such as high blood pressure or aggressive behavior. The tend-and-befriend

regulatory(调节的) system may protect women against stress, and this may explain why women on

average live longer than men.
