Transduction Ontology and Clinical Psychodynamics: An Emotional Inertia Model Based on Variable-Mass Systems

When patients describe emotions as "heavy" or "numb," clinical psychology faces a quantification crisis: we cannot measure this "weight" while remaining trapped in the either/or dichotomy of neural reductionism and dualism.This paper introduces Supplementation Theory and Transworld Energy Dynamics (TWE-AD), conceptualizing the psychological domain as an emergent superstructure—a computational simulation of the physical world yet endowed with independent causal powers such as evaluation and counterfactual reasoning.On the phenomenological timescale (seconds to minutes), emotions are reconceptualized as quasi-classical dynamics within variable-mass systems: psychological mass is dynamically regulated by three dimensions—survival weighting, attention, and authenticity—orbiting the virtual attractor of the "Imagined Satisfaction State" (ISS).Accordingly, depression manifests as a zero-mass trap (m→0), anxiety as underdamped oscillation (η→0), and trauma as mass-inertia solidification. This framework provides computational psychiatry with a pathway from symptom classification to dynamic parameter diagnosis, enabling formal descriptions of subjective experience without reducing the psychological to the physical. --- This is the English translation of the original Chinese version published at [V1 DOI: 10.5281/zenodo.18897285].
