The Non-Linear Physiology–Behavior Equation™

For decades, human behavior has been interpreted through fragmented disciplinary lenses. Psychology emphasized cognition and emotion. Behavioral science focused on antecedents and consequences. Neuroscience examined circuitry. Medicine examined pathology. Education examined motivation and performance. Yet a central scientific problem remained unresolved:Why can identical environmental conditions produce profoundly different behavioral outcomes across individuals, settings, and physiological states?The Non-Linear Physiology–Behavior Equation™ introduces a physiology-centered framework proposing that behavior is not the direct product of antecedents, consequences, cognition, or intention alone, but the downstream expression of dynamically organized physiological state.Grounded in the equation:A ↔ P ↔ C↓Bthe book advances a non-linear interdisciplinary model integrating autonomic regulation, interoception, predictive processing, stress physiology, sensory organization, emotional regulation, cortical accessibility, adaptive load dynamics, and state-dependent learning into a unified architecture of human behavior.Through this framework, behavioral variability, emotional dysregulation, inconsistent learning, executive dysfunction, sensory overwhelm, communication collapse, and fluctuations in adaptive functioning become interpretable through the changing organization of physiological state (P) across time and conditions.This volume introduces the foundational architecture of Behavioral Physiology Science™, including:the BP-Laws™,physiology-centered behavioral interpretation,the Interoceptive Communication Model (ICM 2.0™),state-dependent learning theory,adaptive load dynamics,physiological accessibility,and interdisciplinary applications across behavioral science, medicine, psychology, neuroscience, education, and allied health systems.Designed for behavior analysts, physicians, psychologists, neuroscientists, educators, occupational therapists, speech-language pathologists, mental health professionals, and interdisciplinary researchers, this work proposes a scientifically investigable framework for understanding behavior through the dynamic organization of the human physiological system.This foundational framework expands upon the author’s interdisciplinary publications including:Gomez Uncu, Y.
