Human behaviour is typically analysed through its observable manifestations, such as actions, decisions, emotional expressions, or physiological responses. However, these observable outcomes represent only the surface of a broader and largely unexamined phenomenon: the internal dynamics that precede and shape behaviour in real time. Contemporary approaches in behavioural science, neuroscience, and cognitive modelling often rely on external measurements or retrospective self-reports, which provide limited access to the continuous fluctuations occurring within lived experience. This article introduces a structured first-person methodology designed to observe and document internal cognitive-emotional dynamics as they unfold in real time. The proposed approach organises observation along five complementary axes—sensory, attentional, emotional, cognitive, and decisional—while emphasising descriptive neutrality, temporal precision, and systematic recording of internal transitions. Applied repeatedly in naturalistic contexts, the method reveals recurring forms of internal organisation, including attentional fluctuations, emergence and resolution of internal tensions, rapid transitions, stabilisation phases, and cyclical patterns. These observations suggest that internal dynamics can be described as structured processes rather than static mental states. Although exploratory and based on a single-case methodological investigation, the study demonstrates the feasibility of integrating disciplined first-person observation into behavioural research. The framework provides a potential bridge between phenomenological accounts of experience and contemporary dynamic approaches to cognition, opening avenues for future empirical, theoretical, and computational developments.

This preprint proposes a structured first-person methodology for observing internal cognitive-emotional dynamics in real time. The work explores how attentional, emotional, cognitive and decisional processes evolve before observable behaviour. It aims to provide a methodological bridge between phenomenological observation and contemporary dynamic approaches in cognitive science.
