New Study on Brain: It Sees Things You Don't

"Sanguinetti's study indicates that in our everyday life, as we walk down the street, for example, our brains may recognize many meaningful objects in the visual scene, but ultimately we are aware of only a handful of those objects. The brain is working to provide us with the best, most useful possible interpretation of the visual world, Sanguinetti said, an interpretation that does not necessarily include all the information in the visual input."

This validates the principle behind subliminal perception and gives us reason to use caution with what children see.  We must ask how they are processing?  Can they at certain ages?
