Advocates of Structuralist theories of phenomenal intentionality maintain that the content of perceptual experiences depends on the relations among their phenomenal components. This paper extends this view beyond basic perceptual experiences to mental imagery and experiences of seeing-as without relying on cognitive phenomenology. I develop a Structuralist account of mental imagery that distinguishes between two types of imaginative content, one of which is determined by an image’s sensory phenomenal character, while the other derives from the representation that produced the image. (...) This proposal is then combined with a treatment of certain representations I call perceptual concepts to provide a Structuralist account of experiences of seeing-as. On this account, the deployment of perceptual concepts in experiences of seeing-as alters the phenomenal character and content of such experiences by imbuing them with imagery, thereby making them perceptual/imaginative hybrids.
