Research in cognitive neuroscience indicates that we process the space surrounding our body in a specific way, both for protecting our body from immediate danger and for interacting with the environment. This research has direct implications for philosophical issues as diverse as self-location, sensorimotor theories of perception, and affective perception. This chapter briefly describes the overall directions that some of these discussions might take. But, beforehand, it is important to fully grasp what the notion of peripersonal space involves. One of the most difficult questions that the field has had to face these past 30 years is to define peripersonal space. Although it bears some relations to the social notion of personal space, to the sensorimotor notion of reaching space and to the spatial notion of egocentric space, there is something unique about peripersonal space and the special way we represent it. One of the main challenges is thus to offer a satisfactory definition of peripersonal space that is specific enough to account for its peculiar spatial, multisensory, plastic, and motor properties. Emphasis can be put on perception or on action, but also on impact prediction or defence preparation. However, each new definition brings with it new methods to experimentally investigate peripersonal space. There is then the risk of losing the unity of the notion of peripersonal space within this multiplicity of conceptions and methods. This chapter offers an overview of the key notions in the field, the way they have been operationalized, and the questions they leave open.

The brain evolved to give special representation to the space immediately around the body. One of the most obvious adaptive uses of that peripersonal space is self-protection. It is a safety buffer zone, and intrusions can trigger a suite of protective behaviours. Perhaps less obvious is the possible relationship between that complex protective mechanism and social signalling. Standing tall, cringing, power poses and handshakes, even coquettish tilts of the head that expose the neck, may all relate in some manner to that safety buffer, signalling to others that one’s protective mechanisms are heightened (when anxious) or reduced (when confident). Here I propose that some of our most fundamental human emotional expressions such as smiling, laughing, and crying may also have a specific evolutionary relationship to the buffer zone around the body, deriving ultimately from the reflexive actions that protect us.
