 The implication of this work is that positive emotions have inherent value to human growth and development and cultivation of these emotions will help people lead fuller lives.Studies from Fredrickson's lab have randomly assigned participants to watch films that induce positive emotions such as amusement and contentment, negative emotions such as fear and sadness, or no emotions.Compared to people in the other conditions, participants who experience positive emotions show heightened levels of creativity, inventiveness, and "big picture" perceptual focus.
