Question

Quizplus · Accepted Answer

A reflexive smile is an automatic, unlearned response that occurs without external stimuli, often during sleep, and is present in infants from birth up to the age of one or two months. Genuine smiles occur in response to external stimuli and are a learned behavior that develops later on. Social smiles, on the other hand, are a type of genuine smile that is used to communicate and build relationships with others. False smiles are intentional, insincere smiles that are used to deceive or manipulate others.
