Subjectica: A Lateralized Embodied Model of Cognitive Stance

The mind–body problem remains a central unresolved issue in contemporary cognitive science. Although research on hemispheric asymmetry has yielded extensive knowledge about neural specialization and functional localization, it provides limited explanatory power for how lateralized neural processes become expressed as observable embodied behavior. Existing approaches typically treat bodily asymmetry either as an epiphenomenon or as a static anatomical correspondence, leaving a conceptual and operational gap between neural activity, subjective experience, and kinematic expression.This manuscript presents Subjectica, a purely theoretical neurophenomenological model that addresses this gap by conceptualizing hemispheric asymmetry as a dynamic, embodied process. Rather than positing a fixed mapping between hemispheres and body sides, the model frames lateralization as a continuous sensorimotor pattern manifested through bodily kinematics. Cognitive stance is thus understood as an embodied orientation that becomes observable through structured asymmetries in posture, movement, and segmental motor activity.The model introduces four interrelated operational constructs: Personal-Oriented Left Side (PO-LS), Society-Oriented Right Side (SO-RS), Asymmetric Neurobehavioral Signal (ANS), and Body Segments (BS). Together, these constructs function as interpretative intermediaries linking hemispheric functional dominance, phenomenological orientation, and measurable bodily dynamics. The framework enables the analysis of lateralization through continuous, probabilistic patterns of whole-body and segment-level motor dominance, rather than through discrete anatomical or task-specific indicators.Subjectica is intended as a generative theoretical framework that produces testable hypotheses and operational pathways for future empirical research at the intersection of embodied cognition, hemispheric asymmetry, and neurophenomenology.
