Final answer:
Infants' preference for synchronized audio-visual information showcases their multisensory perceptual abilities, related to the sensorimotor stage of cognitive development.
Step-by-step explanation:
Infants prefer to watch videos where the visual and auditory information is in sync because it demonstrates their multisensory perceptual abilities. This preference is intricately tied to their cognitive development, particularly during the sensorimotor stage, which is the first stage in Piaget's theory of cognitive development. From birth through age two, children learn about the world primarily through their senses and motor behavior.
Their perceptual skills are significant even from a very young age, helping to facilitate interactions with caregivers and the environment. For instance, newborns show a preference for their mother's voice, indicating early development in the realm of cognitive development in terms of language recognition and emotional bonding.
