 According to another proposal about spatial experiences, made by Cussins (1990), experiences of space consist in the subject’s having abilities to move in certain ways. On this view, to experience a sound as coming from the left is to know how to locate the place it is coming from, where this knowledge is practical knowledge about how to move through the environment. Having these abilities, according to Cussins, enables the subject to form beliefs and other mental states that are assessable for accuracy (or that have contents in our sense); but the abilities themselves, which are supposed to constitute experiences, are not; and even a creature who hadn’t yet or couldn’t form such states could still have the abilities. To have the abilities, according to Cussins, is to be presented with locations in experience. In his 1990 he calls this way of being presented with locations construction-theoretic content (where this kind of ‘content’ is not assessable for truth).
