Code Psychology: How Organic Codes Create Mind

Code Psychology extends Marcello Barbieri’s Code Biology paradigm to psychological phenomena, proposing that mental processes operate through organic codes—arbitrary rule-based mappings between neural signals (signs) and subjective experiences (meanings) mediated by adaptors. This theoretical framework addresses persistent epistemological challenges in psychology, including mind–body dualism, the debate between reductionism and holism, and the tension between universal and subjective experiences. I propose to integrate Code Biology’s triadic structure with contemporary neuroscience, particularly the free energy principle, affective neuroscience, and biogenetic structuralism’s neurognostic structures. The framework reconceptualizes psychological disorders as disruptions in metacode organization, exemplified through autism spectrum disorder, where distinct neural adaptor configurations create systematic cognitive variations rather than deficits. Drawing on thermodynamic principles, we propose that the psyche minimizes variational free energy through codepoiesis—the ongoing generation and conservation of codes that assemble adaptive meanings. This synthesis unifies insights from Marcello Barbieri, Carl Jung, Ross Ashby, Karl Friston, and Jaak Panksepp, revealing the mind as a predictive system that bounds uncertainty via action-oriented inference. Code Psychology offers testable hypotheses for empirical validation through neuroimaging, genomic modeling, and high-dimensional cytometry, providing a mechanistic yet holistic account of mental phenomena that bridges the metaphoric and material at the interface of code, energy, and matter.
