Sender repertoires of pure and blended facial expressions of emotion

Six actors attempted to communicate by facial expression seven assumedly basic emotions (pleasure, surprise, fear, hate, sorrow, disgust and interest), and all pairwise blends, e.g., fear+sorrow. One hundred and eighty-two subjects (divided into groups as to the six actors) judged pictures of these emotions by three methods: (1) mapping, placing the pictures on coordinate systems with denotated axes, (2) identification and (3) sorting similar emotions into the same pile, followed by multidimensional scaling and cluster analyses. Recognition of the emotions was fairly good, though not equally good for all emotions and their blends; also the actors' ability to express emotions varied. Emotions of opposite hedonic tone did not blend well. Interest seemed to lend poignancy to the basic emotion with which it was blended rather than to constitute an emotion in itself. Expressions seemed to be more easily identified if the actor did not try to feel the emotion too deeply.
