I found this on Gizmodo this morning. It's a map showing the research for where on the body each emotion affects you physically. The actual research is linked in the post. It looks about right to me. Most of the time the physical symptoms of your emotions are pretty subtle. But if you've got characters going through some powerful emotions, it might be a nice touch to include them. Where Emotions Hit You, Visualized Notice, for instance, the hands on contempt.
