Now I have to admit, these are the worst studies my lab has ever run. 现在我要承认,这个是我实验室里进行过的最糟糕的实验。
Because the tickle 1 sensation on the palm comes and goes, you need large numbers of subjects with these stars making them significant. 因为痒痒的感觉就像昙花一现,所以需要大量的试验者,还只能靠星级来给痒痒的程度打分。
So we were looking for a much more objective way to assess this phenomena 2. 所以我们需要一个更客观的办法来评估这个现象。
And in the intervening years I had two daughters. 其间几年中,我有了两个女儿。
And one thing you notice about children in backseats of cars on long journeys, 于是关于长途旅行里小孩子坐在后座上,你注意到一件事,
they get into fights -- which started with one of them doing something to the other, the other retaliating 3. 那就是他们会互相掐架--开始于其中一个对另一个动了什么手脚,另一个就要还手。
It quickly escalates 5. And children tend to get into fights which escalate 4 in terms of force. 然后冲突很快就会升级。而小孩子们之间的冲突升级一般都体现在用力大小上。
Now when I screamed at my children to stop, sometimes they would both say to me the other person hit them harder. 于是我嚷嚷着叫我的孩子们住手的时候,有的时候她们俩都会告诉我,对方下手比自己更重。
Now I happen to know my children don't lie, so I thought, as a neuroscientist, 我恰好知道我的孩子们不会说假话,所以作为一个神经学家,
and it was important how I could explain how they were telling inconsistent truths. 我想我如何解释两人自相矛盾的真话应该是很重要的吧。
And we hypothesize based on the tickling 6 study that when one child hits another, they generate the movement command. 于是我们根据挠痒痒的实验做出了假设,就是当一个孩子打另一个的时候,会生成动作命令。
They predict the sensory 7 consequences and subtract it off. 他们预测出了感知到的结果,然后减掉了。
So they actually think they've hit the person less hard than they have -- rather like the tickling. 实际上他们以为他们下手比真正要轻,和挠痒的道理类似。
Whereas the passive recipient 8 doesn't make the prediction, feels the full blow. 然而那个被打的孩子没有做预测,感觉到了全部的打击。
So if they retaliate 9 with the same force, the first person will think it's been escalated 10. 所以他们用同样这个打击的力气还手的话,第一个人会觉得力气变大,冲突升级了。
