Contempt facial expression

Other cultures can differ greatly from your own, but there are commonalties in the way we express emotions. Researchers from UC Berkeley and Google Research used machine learning and YouTube videos to compare common facial expressions to the situations that prompt them. The study was published in Nature. The researchers logged the facial expressions of six million videos using a machine learning algorithm. These videos were made by people from different countries representing all corners of the Earth and featured various situations and subjects.

A microexpression is a facial expression that only lasts for a short moment. It is the innate result of a voluntary and an involuntary emotional response occurring simultaneously and conflicting with one another, and occurs when the amygdala the emotion center of the brain [ dubious — discuss ] responds appropriately to the stimuli that the individual experiences and the individual wishes to conceal this specific emotion. This results in the individual very briefly displaying their true emotions followed by a false emotional reaction. Human emotions are an unconscious biopsychosocial reaction that derives from the amygdala and they typically last 0. Microexpressions cannot be controlled as they happen in a fraction of a second, but it is possible to capture someone's expressions with a high speed camera and replay them at much slower speeds. Nevertheless, in the s, Paul Ekman expanded his list of emotions, including a range of positive and negative emotions not all of which are encoded in facial muscles. These emotions are amusement, embarrassment, anxiety, guilt, pride, relief, contentment, pleasure, and shame.
