Here's some research showing where kids better than adults: children are better recognizers of the visual differences (the study used pictures of different animals). It may be that everything is more novel to them and they more interested, but reflects Ohio State University researcher Vladmir Sloutsky, "As people become smarter, they start to put things into categories, and one of the costs they pay is lower memory accuracy for individual differences." Interestingly, adults regained that child-like memory for differences if they were shown novel and completely imaginary figures.
This like those "child-like" creative geniuses you read about biographical accounts. These men and women have a "child-like" way of seeing familiar things as if for the first time.
