Question

Quizplus · Accepted Answer

Duchenne smiles, also known as genuine or authentic smiles, involve contraction of both the zygomatic major muscle (which lifts the corners of the mouth) and the orbicularis oculi muscle (which produces crinkling around the eyes). This type of smile is involuntary and reflects genuine positive emotion. Option B is incorrect because Duchenne smiles are not intentional or forced. Option C is incorrect because the smile involves more than just the lifting of the corners of the mouth.
