New research from the Institute of Neuroscience and Psychology at the University of Glasgow, published this week in Current Biology, says the range of human emotion may be a little closer to a teaspoon than previously thought, according to The Atlantic.
Conventional scientific wisdom recognizes six "classic" emotions: happy, surprised, afraid, disgusted, angry, and sad. But the Glasgow scientists studied people's facial expressions, and the emotions they signal, by showing people computer-generated facial animations. They asked the observers to characterize the faces based on those six basic emotions, and found that anger and disgust looked very similar to the observers in the early stages, as did fear and surprise. For example, both anger and disgust share a wrinkled nose, and both surprise and fear share raised eyebrows.
