Peripersonal space as the haptic field

A topic of interest in the philosophy of perception concerns similarities and differences between the senses. One way of approaching this issue is to focus on structural differences. An interesting question in this respect concerns whether, and in what respect, perceptual modalities other than vision might possess a spatial field which is in some respects similar to the visual field. This paper argues that haptic touch is structured by an external spatial field, namely peripersonal space. I first provide a clarification of the general characteristics of an external spatial field. The paper then outlines the notion of peripersonal space. Finally, I argue that peripersonal space functions as the external spatial field of haptic touch insofar as it meets the necessary conditions for a spatial field.
