The Emotional Intelligence Framework (EIF): A Physiology-Informed Model of State-Dependent Emotional Accessibility introduces a conceptual framework for understanding emotional functioning as a dynamic, state-dependent, and context-sensitive process. The framework proposes that emotional intelligence reflects not only the presence of emotional capacities such as empathy, emotional awareness, emotional regulation, and relational reciprocity, but also the degree to which these capacities remain accessible under changing physiological, contextual, interpersonal, and ecological conditions. The Emotional Intelligence Framework (EIF) distinguishes emotional competence from emotional accessibility and introduces the concept of Emotional Accessibility Compression, defined as a temporary narrowing of access to emotional repertoires under conditions of cumulative adaptive load. Grounded in physiology-informed, nonlinear, ecological, interoceptive, and dynamic systems perspectives, the framework conceptualizes emotional functioning as an emergent process arising from interactions among physiological regulation, adaptive load, contextual influences, interpersonal processes, recovery resources, and environmental conditions. Situated within the broader Non-Linear Physiology–Behavior Equation™ framework, the EIF conceptualizes emotional accessibility as a dynamic organizational process that may fluctuate across varying physiological and ecological conditions while underlying emotional capacities remain intact. The framework is not intended to replace existing theories of emotional intelligence, emotional regulation, development, or behavior. Rather, it is proposed as an integrative and interdisciplinary model for examining state-dependent variability in emotional accessibility across natural environments and over time. The EIF is presented as an exploratory conceptual framework intended to support future empirical investigation through repeated-measures ecological studies, longitudinal research, physiology-informed observation, and other interdisciplinary approaches aimed at evaluating emotional accessibility across diverse populations and contexts.
