Dr. Yoandra M. Gomez Uncu’s research centers on the Non-Linear Physiology–Behavior Equation™, a physiology-centered theoretical framework proposing that human behavior emerges as a dynamic, state-dependent outcome of continuously interacting physiological systems rather than as an isolated linear response to environmental contingencies alone.

Within the framework:

A↔P↔C

Antecedents (A), Physiological State (P), and Consequences (C) interact continuously within a non-linear physiological system, while behavior (B) represents the downstream expression of the organism’s physiological organization at a given moment in time.

Her work proposes that physiological state functions as a dynamic organizing variable influencing accessibility to executive functioning, emotional regulation, learning, communication, social engagement, behavioral flexibility, adaptive performance, and cognitive accessibility across changing internal and environmental conditions.

The broader objective of this research is to contribute toward a unified interdisciplinary framework capable of integrating observations that have historically remained fragmented across scientific disciplines. The framework draws from and seeks to connect findings from behavior analysis, physiology, neuroscience, autonomic regulation, interoception, neuroendocrinology, stress physiology, trauma science, cognitive science, embodied cognition, psychiatry, developmental science, dynamic systems theory, rehabilitation sciences, education, and human performance research within a single non-linear interpretive architecture.

Rather than treating cognition, emotion, behavior, physiology, and environmental interaction as independent or competing explanatory domains, the Non-Linear Physiology–Behavior Equation™ conceptualizes them as continuously interacting components of an integrated physiological-behavioral system.

A central principle of the framework is that functional capacity and functional accessibility are not always equivalent. An individual may possess knowledge, skills, emotional insight, communication abilities, or learned behavioral repertoires while simultaneously experiencing temporary reductions in accessibility to those capacities under conditions of cumulative physiological load, autonomic dysregulation, chronic stress, trauma-related activation, sensory overload, metabolic instability, or adaptive narrowing.

Building upon this theoretical foundation, Dr. Gomez Uncu developed additional physiology-centered conceptual frameworks, including the Functional Regulation Assessment (FRA™), Regulation Before Instruction (RBI™), and the Interoceptive Communication Model (ICM 2.0™), which further explore how physiological organization may influence behavioral interpretation, instructional accessibility, emotional regulation, adaptive functioning, and real-time cognitive performance across clinical, educational, developmental, and mental health contexts.

Collectively, this body of work advances a physiology-centered, state-dependent perspective proposing that variability in human behavior may often reflect dynamic changes in physiological organization rather than fixed deficits, lack of motivation, or stable trait limitations alone.
