Abstract

The apparent failure of infants to understand “object permanence” by reaching for hidden objects is perhaps the most striking and debated phenomenon in cognitive development. Of particular interest is the extent to which infants perceive and remember objects in a similar way to that of adults. Here we report two findings that clarify infant object processing. The first is that six-month-old infants are sensitive to visual cues to occlusion—particularly gradual deletion. The second finding is that oscillatory EEG activity recorded over right temporal channels is involved in object maintenance. This effect only occurs following disappearance in a manner consistent with occlusion, and the object's continued existence.
