Reliability of the Core Emotion Framework Scale: Psychometric Validation, Multi-Scale Synthesis, and Preliminary Empirical Evidence from Pilot Study 3

The landscape of contemporary affective science is characterized by a fundamental tension between classical essentialist models, which view emotions as discrete, hardwired biological categories, and modern constructivist perspectives, which treat emotions as emergent, situated states constructed from a complex interplay of interoception, past experience, and contextual concepts. The Core Emotion Framework (CEF) proposes a structural-constructivist synthesis designed to resolve this divide by conceptualizing the human psyche as a coordinated "Human Operating System" (Human OS). This architecture is built upon ten irreducible functional operators distributed across three primary neural hubs: the Head (Cognitive-Regulatory), the Heart (Relational-Affective), and the Gut (Conative-Existential). Central to the clinical and academic utility of this framework is the development of the CEF Scale—a psychometric instrument designed to measure an individual's reflexive and deliberate emotional capacities. This report provides an exhaustive analysis of the reliability, construct validity, and empirical foundations of the CEF Scale, incorporating the preliminary findings of Pilot Study 3 (N\ =\ 39) to establish a robust, citable baseline for researchers in the fields of psychological science and affective neuroscience.
