Question

Quizplus · Accepted Answer

The preference for a pacifier previously sucked on indicates that infants have integrated touch (the sensation of the pacifier in their mouth) and vision (the appearance of the pacifier) to form a memory. This suggests that the two senses can be integrated early in life. The other answer choices do not provide direct evidence for the integration of touch and vision.
