Findings indicated that 5-month-olds succeeded in reasoning about the interaction of a visible and a hidden object even though the 2 objects were never simultaneously visible and a 3- or 4-minute delay preceded…

The results revealed two developments, one in infants' knowledge of when objects should and should not be occluded and the other in infants' ability to posit additional objects to make sense of events that would otherwise violate their…
