Question

Quizplus · Accepted Answer

Studies have shown that very young infants (as young as a few days old) show similar facial expressions of taste when presented with sweet, sour, and bitter tastes, suggesting that the link between taste and facial expressions is innate and not learned or culturally defined. Infants also show a preference for sweet tastes and a dislike for bitter tastes, which supports the idea that this innate link has evolutionary significance. There is little evidence to suggest that infants are learning their facial expressions of taste by observing their parents.
