Laura cries. She sobs. She holds her head in her hands. Watch her be sad and let the tears go. Is she really crying or is she trying to get your attention? You wonder. Are those tears real or is there a manipulative game that she's playing? But suddenly, you have sympathy on her. You want to comfort her and make her feel better. Snap! Suddenly you want to punish her. Snap! Suddenly you realize that you just need to let her cry it out. It's hot to watch her cry. And this is the essence of our psychophysical experiment.
