Final answer:
Infants develop depth perception and intermodal perception during their early months and years of life. Depth perception starts to develop after an infant becomes mobile, while intermodal perception involves integrating information from multiple senses.
Step-by-step explanation:
Infants develop depth perception and intermodal perception during their early months and years of life. Depth perception, the ability to see in three dimensions, starts to develop after an infant becomes mobile. It continues to develop throughout early childhood. Intermodal perception, on the other hand, is the ability to integrate information from multiple senses, such as vision and hearing. Infants start to develop intermodal perception early in life as they learn to associate sights and sounds.
