A « world within a world » could be the title for which the Autistic Knowledge Space would be the core conjecture. The ROAL-model (Bakrim, 2020, 2021, 2022, 2024, 2025) has been formulating and verifying this latter from a non-therapeutic viewpoint of duality, through epistemic particles, spectral plane and Brain-physical mapping of the the spectrum grounding in Cognition Emotion Action individuals or the ternary structure of language-consciousness. To date, the set of duality splits and inversion relying on framing (typical)/antiframing (divergent) have enabled observatio-nal formulas and theoretical formulas such as : Participational event diathesis: actp1fact p1/ factp2act p2, Act event diathesis (action/emotion) and AE   / EA, Neurotype plane diathesis:  Kg/Gk . From our brain computational model, the duality principle being a mathematical mapping between two rea-soning/inferential sets or the Semiome (graph projection semiotics) implies the hypothetic relation between our brain mathematical model (nD- Higher epistemic-mathematical properties and 3D Brain manifold (cortex) for lower epistemic-mathematical properties) and the duality between pro-jective graph spaces and graph properties of the aforementioned CEA individuals (cycle and distri-bution properties) of which prime number relevance ( Bershadskii, 2011) for modularity (Chellig, Fountoulakis, Skerman, 2021) and modular  framing/antiframing duality, especially neuro-degenerative results on the latter. 

Hence, under consideration of perceptual inversion, in particular ’’perceptual autistic acts’’ and their pertinence in exteroceptive, interoceptive and proprioceptive spheres (Cuppini, 2012- Lourei-ro, Ringold, Lisa, 2024- Neklyudova, A et al, 2022 - Noel, Lytle, Cascio, Wallace, T, M, 2018- Proff, Williams, Garfinkel, 2022 -  Zhang,  2020, - Buzsaki, 2006), relying on Sensor, Control, Ef-fector roles, embedded sequences of linguistic/non-linguistic individuals and their rotational  plane axes (source, effectuator, target) are submitted to a co-semiotic symptomatology of delta-explanability and delta-interpretability and will be applied to our results following a bi-morphic observation function. Therefore, grounding in a monistic model where the observation function swaps scientific(n-autistic) / semiotic (n-1 typical) and semiotic (n-1 autistic) / scientific (n typi-cal). Moreover, higher and lower epistemic-mathematical properties of sets, types and categories indicate a computational model for  brain-consciousness in autism (genome/transcriptome, dy-nome, connectome, cognome and communicome/symbiome).

This research aims at studying  duality and co-semioticity in diagnosed autistic participants (ado-lescent and children) focusing on modular sequencing principles on text levels (truncation in sylla-ble rythmic dimensions, phonomorphological, morphosyntactic levels...). The novelty of the ap-proach is the experimental and brain-phyical obtaining of a spectrum result representation of CEA individuals along with symptomatic plotting.
