Question

Quizplus · Accepted Answer

A social smile is a smile that is a response to a social interaction or communication, rather than just reflecting an infant's internal state. The fact that the infant smiles when someone catches her attention suggests that she is responding to social stimuli, indicating a social smile. Option B, conditioned stimulus, refers to a stimulus that becomes associated with a specific response through learning, which is not relevant in this scenario. Option C, learned emotion, is not applicable in this context because emotions are not learned per se, although they can be shaped by experience. Option D, motor expression, refers to the outward manifestation of a particular motor response, which is too broad to apply in this specific scenario without further details.
