Well, what you do is, if you take any one of you here, and put you in front of a screen, and measure your galvanic skin response, and show pictures on the screen, I can measure how you sweat when you see an object, like a table or an umbrella. Of course, you don't sweat.
你要做的是，如果你找来一个人，在他面前放一面屏幕， 一边测量他的皮肤电反应， 一边在屏幕上放图片给他看， 我能测量你看见一个物体出汗的情况， 比如一张桌子或一把伞时，当然你不会出汗，
