QUOTE : In 2008, Lawrence Williams and John Bargh conducted a study where they had people meet strangers. One group held a cup of warm coffee, and the other group held iced coffee. Later, when asked to rate the stranger’s personality, the people who held the warm coffee said they found the stranger to be nice, generous, and caring. The other group said the same person was difficult, standoffish, hard to talk to. In another round of research subjects held either a heating pad or a cold pack and then were asked to look at various products and judge their overall quality. Once they had done this, the experimenters told them they could choose a gift to keep for participating or they could give the gift to someone else. Those who held the heating pad chose to give away their reward 54 percent of the time, but only 25 percent of the cold pack group shared. The groups had turned their physical sensations into words, and then used those words as metaphors to explain their perceptions or predict their own actions.
