Key Points

The study aims to explore whether cognitive discrepancies in high-ability ASD can stratify individuals into different cortical field geometries.
Resting-state fMRI study applying Cortical Informational Field Theory to analyze ASD subgroups.
Cortical field geometry measured using four global optimization observables across different cohorts.
Comparative analysis conducted on subgroups including NT, ASD 2e Compensated, and ASD 2e Overloaded with a sample size of n=159.
No significant differences were found between groups after false discovery rate (FDR) correction (best p_FDR=0.182).
Robustness analyses revealed that observed trends were not stable across different analytical choices.
The findings provide a baseline for future studies to replicate with larger power and anatomical validation.

Abstract

This preprint reports a resting-state fMRI study applying the Cortical Informational Field Theory (CIFT) Ginzburg-Landau framework to test whether VIQ-PIQ cognitive discrepancy stratifies high-ability ASD (FIQ ≥ 120, termed twice-exceptional or 2e) into distinct cortical field geometry regimes. Four GL observables — global efficiency (ξₑ), local clustering (C₁), mid/long-range clustering (C₂), and field curvature (R) — were computed from ABIDE I (n=159, CC200 atlas, 14 sites, neuroCombat harmonization) and compared across NT (n=83), ASD 2e Compensated (n=54), and ASD 2e Overloaded (n=22) subgroups. No GL observable survived FDR correction (best pFDR=0. 182). Three robustness analyses — global FC magnitude control, VIQ-PIQ threshold multiverse 10, 12, 15, 18, 20, 25, and segmented changepoint modelling — showed that uncorrected directional trends are not stable across analytic choices. These results constitute a fully characterized null motivating pre-registered replication with adequate power (n ≥ 36 Overloaded), anatomically validated C₂, and a pre-specified VIQ-PIQ threshold. Submitted to Brain Sciences (MDPI).
