<p>A prevalent philosophical view holds that information about the self remains implicit in perceptual representation. While it correctly describes the most basic perceptual representations, I argue that this view does not hold for more complex, but still low-level, perceptual representations of space. I propose that in the course of perceptual processing, implicit information about the self is made explicit. My discussion centers on a detailed study of egocentric reference frames. I suggest that within the perceptual system of a creature, these reference frames form a hierarchy, in which each frame that is implicit at one stage of perceptual processing is explicit at the next. This hierarchy allows implicit information about the self to be articulated as processing advances. I show how standard explanations of two perceptual phenomena – gaze shifts and the illusory experience of self-motion – are committed to and thus support this hierarchical picture.</p>
