美国斯坦福大学神经生物学家卡纶·帕克教授做了一个科研实验:让小猴每周都与母猴分开一个小时,并在这段时间里对它们的荷尔蒙做出测量。帕克发现,在小猴离群半个多小时后,压力指数明显增大,而在小猴回到猴群后,母猴会立刻安抚它们,压力指数很快会与从未离群的小猴持平。但在以 Professor Carl Parker, a neurobiologist at Stanford University in the United States, conducted a research experiment in which the monkeys were separated from the female monkey by an hour each week and their hormones were measured during this time. Parker found that the pressure index increased significantly more than half an hour after the monkeys were out of the group, and the monkeys immediately appeased them after the monkeys returned to the monkeys, and the stress index quickly became associated with the monkeys Flat.
