Question

Quizplus · Accepted Answer

The preference for a particular pacifier after sucking on it suggests that infants have integrated touch and vision, as they are able to recognize and remember the object both by its shape and texture. This experiment has been replicated many times with consistent results. Choices B and C suggest that infants are capable of sensing touch, but do not necessarily indicate integration with vision. Choice D suggests recognition and memory, but does not specifically test for integration of touch and vision.
