The views expressed here do not necessarily reflect the views of these organizations. Facial expressions are important parts of how we communicate and how we develop impressions of the people around us. He hypothesized that certain facial expressions are innate, and therefore universally expressed and recognized across all cultures. They enlisted members of the Fore tribe in Papua New Guinea, who at the time had little contact with Western culture, to do an emotion recognition task. The researchers also took photos of the facial expressions of the Fore people and showed them to Americans later.
They are extremely important to the social interaction of individuals. Background scenes in which faces are perceived provide important contextual information for facial expression processing. The purpose of this study was to explore the time course of emotional congruency effects in processing faces and scenes simultaneously by recording event-related potentials ERPs. The behavioral results found that the categorization of facial expression was faster and more accurate when the face was emotionally congruent than incongruent with the emotion displayed by the scene. In ERPs the late positive potential LPP amplitudes were modulated by the emotional congruency between faces and scenes.
