These are widely regarded as the main types of emotion experienced by humans, but until recently it was believed that humans could express all of these 6 emotions via expressions on their face. In actual fact we can’t, we are only capable of exhibiting 4. The original belief was based on Dr Paul Ekman’s theory of the above 6 emotions, but this has been somewhat challenged by new research presented in the Current Biology journal asserting that there are in fact only 4 emotions. What these actual emotions are is unclear as there is difficulty differentiating between say fear and surprise, or anger and disgust, but the conclusion was based on the range of different muscles in the face (aka action units) involved in signalling different emotions and the overlap there seems to be between certain emotions.
