Jonah Lehrer reveals what infants see and how it differs from what we see. He writes that "if attention is like a focused beam in adults, then it’s more like a glowing bulb in babies, casting a diffuse radiance across the world":

The experiment itself involved tracking the eye movements of infants between 6 and 15 months of age. The researchers used a special stimuli known as a Mooney face. ... [T]he only way to see the shadowed faces is to stare straight at them – unless we pay attention the faces remain incomprehensible, just a mass of black and white splotches. In this experiment, however, the babies were able to perceive the faces even when they were located in the periphery of their visual field. (Trust me: You can’t do this.) Because their lantern was so diffuse, they were able to notice stimuli on a much vaster sensory stage.
