Traditional abnormal psychology, centered on symptom inventories and categorical diagnosis, has long been constrained by fragmentation, labeling, and inadequate mechanistic explanation, lacking a unified framework for understanding across disorder categories. Adopting vector psychology as an innovative paradigm, this paper provides a unified account of schizophrenia, depressive spectrum disorders, bipolar spectrum disorders, neurotic spectrum disorders, and psychosomatic disorders, based on the core dimensions of the psychological vector system, dual‑channel processing, self‑structure, and psychological energy. It further examines the associations between emotion, psychological energy, and physiological indicators with reference to classical psychosomatic models, and proposes a psychological energy continuum, psychological genotyping, and a new framework of symptomatology. This study aims to offer an integrative, mechanistically consistent, and clinically applicable foundation for abnormal psychology, facilitating its transformation from classificatory description to theoretical reconstruction. Keywords: vector psychology; psychiatric and psychological disorders; abnormal psychology; psychological energy; embodied intelligence
