Altered alpha-band regulation during naturalistic theory of mind processing in autistic children.
Article in Developmental cognitive neuroscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTheory of Mind (ToM) deficits are a core feature of autism, yet the neural dynamics associated with social-cognitive processing in naturalistic contexts remain unclear. Alpha-band oscillations have been implicated in the regulation of internal attention and may be involved in supporting mentalizing during real-world social interactions.
methodsElectroencephalography (EEG) was recorded from 41 autistic children and 34 typically developing (TD) children aged 3-10 years while they passively viewed a nonverbal animated film. Alpha power (6-9 Hz) in the right temporoparietal junction (rTPJ) and prefrontal cortex (PFC) was examined during Theory of Mind-related scenes and baseline scenes.
resultsTD children showed increased alpha-band activity during ToM-related scenes relative to baseline, whereas autistic children showed no clear context-dependent alpha-band modulation. Exploratory ROI-level analyses further suggested associations between rTPJ alpha modulation and individual differences in ToMI-2 and Childhood Autism Rating Scale (CARS) scores, although these associations did not survive FDR correction.
conclusionsThese findings suggest that typical ToM-related processing involves context-sensitive alpha-band modulation supporting social cognition. In autism, reduced modulation may reflect altered neural regulation during social-cognitive processing rather than diminished regional engagement. Naturalistic EEG paradigms may help identify neural indices of individual differences in social-cognitive functioning, pending further validation.
