As human beings, we experience all kinds of emotions on a daily basis. Sometime, we may even feel that we are experiencing all the emotions in the wheel. Paul Ekman suggested the six basic human emotions are anger, happiness, surprise, disgust, sadness and fear. Before he published his findings in the early 1970s, it was widely believed that facial expressions and their meanings were specific to each culture. However, new research from the Institute of Neuroscience and Psychology at the University of Glasgow, published in Current Biology, says the range of human emotion is a little closer to a teaspoon. This new research suggests there are only 4 basic emotions. They are happy, sad, afraid/surprised, and angry/disgusted.
