Beyond the Zero-Boundary

Edward T. Hall’s classical proxemics framework models interpersonal space up to the zero-boundary (skin contact), beyond which space is conventionally treated as collapsed. Yet in non-consensual bodily violations, spatial dynamics do not cease; they enter negative proxemic space. This paper introduces Dynamic Negative Proxemics (DNP), a formal, quantitative framework that extends proxemic theory past the zero-boundary into negative spatial dimensions. We formalize negative space across seven normalized dimensions: Agency/Consent (A), Depth/Invasion Layer (D), Temporal Duration (T), Relational/Institutional Power (R), Kinetic Intensity (K), Directional Vector (θ), and Valence/Intent (Ψ). We synthesize these dimensions into a gated, bounded intrusion magnitude (M_intrusion) and introduce the concept of the Proxemic Echo (E_proxemic), capturing post-intrusion spatial hypersensitivity, hypervigilance, and persistent baseline expansion. The model generates falsifiable predictions across psychophysiological, behavioral, and clinical domains. DNP offers a rigorous taxonomy and mathematical formalism for modeling boundary violations, institutional betrayal, and post-traumatic spatial reconfiguration.
