Abstract

The concept of the self has been central to both psychological and philosophical discourse, with recent developments emphasizing the 4E approach—embodied, embedded, enacted, and extended cognition. Peripersonal space (PPS), defined as the immediate space surrounding the body, serves as a critical interface between the individual and the external environment, facilitating action and perception. Despite its significance, the role of PPS in shaping various aspects of the self remains underexplored. This article examines how perception within PPS influences different dimensions of the self. That is to say, it affects the narrative self and bodily self through its impact on autobiographical and procedural memory, respectively. Additionally, PPS perception contributes to the minimal self by influencing the sense of bodily ownership. Moreover, this understanding offers significant implications for technological applications. On the one hand, it reveals methods by which individuals' memories and sense of self can be influenced through the manipulation of peripersonal perception. On the other hand, it underscores the role of technology in prompting a reevaluation of the concept of self.
