Question

Quizplus · Accepted Answer

Duchenne smiling is characterized by genuine positive emotions and a contraction of both the zygomatic major muscle (the muscle responsible for lifting the corners of the mouth) and the orbicularis oculi muscle (the muscle responsible for crinkling the corners of the eyes), which signals a greater sense of competence and authenticity. This type of smile has also been shown to lead to more supportive social relationships and greater happiness, making it a desirable facial expression to display.
