The number of human emotions used to be six: happiness, sadness, anger, fear, disgust and surprise. Now a team of researchers at the University of California, Berkeley, has created a multidimensional, interactive mapping of interconnected emotional states that is much richer and more subtle than we knew. In their study, 853 people viewed sequences of evocative video clips that included births, weddings, risky stunts, death, suffering, sexual acts and natural disasters. People viewing the clips described a wide range of emotiional states reflected a rich and nuanced array of emotional states.  The researchers found that participants generally shared the same or similar responses to the videos and the data generated enabled them to identify 27 distinct emotional states. Using innovative statistical models and visualization techniques, the team created a semantic map, with each of the 27 emotional categories corresponding to a certain color to shed light on the full palette of emotions.
