Mental-4-Element Framework: A Four-Element Coordinate Model of Human Psychology (v1.5)

This paper proposes a hypothetical integrative framework for the structural mapping of human mental functioning, organized around four elements: Emotion (output), Sensitivity (input), Social Norm Dependency (external control), and Reason-Based Thinking (internal control). v1.5 introduces the following refinements over v1.4: (1) conceptual separation of Aron's "deep processing" from Reason-Based Thinking; (2) Sensitivity formulated as the activation condition for development; (3) Reason-Based Thinking formulated as the accumulation and conversion condition for developmental potential; (4) Environmental Friction redefined as the experience that compels the relativization of "normal"; (5) structural description of the low-Sensitivity profile added.
