The selfish aggressive impulses within us that we hide from the public view to fit in and feel respected and liked by the group.

我们内心自私、好斗的冲动被我们隐藏起来，不让公众看到，以适应并感到被群体尊重和喜欢。

So, for instance, depriving male rats of the kind of rough play they want leads to adult male rats who never learned how to manage their aggressive impulses.

举例来说，剥夺雄性老鼠想要的粗暴玩耍的权利，会导致成年雄性老鼠永远学不会如何控制自己的攻击冲动。
