A Three-Layer Cognitive Structure Theory of “Soma-Emotion-Meaning” Based on Embodied Cognition: Integrating Somatic Marker Hypothesis and Progressive Weakening-Compensation Principle — An Integrative Framework for Understanding Autism Spectrum Disorder and Depression Comorbidity

The comorbidity rate between Autism Spectrum Disorder (ASD) and depression reaches 50%, yet there is a lack of an integrated theoretical framework to guide digital health interventions. Existing research on sensory processing, emotion regulation, and meaning-making is fragmented, which limits the development of technology-enabled treatment solutions. This study integrates embodied cognition theory, the somatic marker hypothesis, and the principle of decreasing entropy and compensation, proposing a three-layer cognitive structure theory of "sensory awareness - emotional awareness - sense of meaning". This framework reveals that the comorbidity of ASD and depression stems from impairments in the three-layer cognitive pathway. Art therapy operates through dual mechanisms: sensory integration activates bottom-up neuroplasticity, while narrative reconstruction achieves top-down cognitive reappraisal. This theoretical model provides clear guidelines for the development of intelligent assessment tools, adaptive intervention algorithms, and data-driven personalized strategies in mobile health applications.
