EEG study: autism alters feedback evaluation, not raw perception
MacrinePhD · x · 2026-11-03
A Hebrew University EEG study found autistic and non-autistic adults achieve identical auditory task accuracy (70%), but differ in how their brains evaluate feedback and update expectations.
Key findings:
- Blunted feedback-related negativity (FRN) after errors
- Minimal neural modulation by task difficulty
- Weaker behavioral adjustment after high-confidence correct trials
All three signatures replicated in follow-up testing 1-2 years later (n=51), and combined in a machine-learning model classified neurotypes with 80% accuracy.
