"Fight or flight! That's the only way we cope with stress," said my professor years ago. For more than sixty years, our competitive nature has been assumed to be related to our built-in sympatho-adreno-medulary (SAM) response system. This is our automatic alarm state that pushes our body to the max so we can do something very aggressive to win over a predator or perceived source of severe stress, or to hightail it away as quickly as possible.
Psychologist Walter Cannon conducted the classic research on the SAM-mediated fight-or-flight response. With laboratory research conducted primarily on male rats, he showed that our body reacts to stress through a sympathetic nervous system surge and associated stress-hormone release sequence. It was assumed that the fight-or-flight response was our only natural intense reaction to perceived stress, but new research by psychologist Shelly Taylor at the University of California, Los Angeles, and her colleagues suggests that learning from male rats has its serious limitations.
