156 A background state is defined as the stable psychophysiological wave on which a person functions outside of emotional peaks or stress responses. This wave sets the limits of perception, regulation capacity, and overall coherence [7, 8, 9]. The model distinguishes five developmental levels of background state: 1. Reactive Level — impulsivity, physical tension, fragmented attention dominate [7]. 2. Affective Level — emotional waves govern behaviour more strongly than intention [8]. 3. Regulatory Level — emergence of basic skills of awareness and self- regulation [7, 9]. 4. Integrated Level — alignment of body, emotion, attention, and action; stable presence appears [9]. 5. Conduit Level — a resonant, coherent wave in which a person acts and observes simultaneously, enabling coherent influence on the environment [7, 10, 11, 12]. Each level is described through four groups of markers: - bodily markers (breath, tone, posture, motor rhythms) [7, 9]; - emotional markers (stability, amplitude, transition speed) [8]; - cognitive markers (focus, attentional coherence, mental fragmentation) [3, 9]; - social-field markers (interaction stability, capacity for resonance) [10, 11, 12]. The model also employs a 0–10 wave coherence scale, which reflects the stability and alignment of the system: from chaotic, reactive states to a stable, resonant conduit-level wave [7, 9]. This operational level makes it possible to: - empirically observe state expressions in natural environments [4, 5]; - track transformations in body, emotion, attention, and interaction [7, 8, 9]; - measure developmental dynamics, rather than describe them abstractly [9]; - integrate qualitative and embodied methods within a unified analytical framework [1, 2, 3].
