Abstract
This article provides a selective overview of recent event-related brain potential (ERP) studies in L2 morpho-syntax, demonstrating that the ERP evidence supporting the critical period hypothesis (CPH) may be less compelling than previously thought. The article starts with a general introduction to ERP methodology and language-related ERP profiles in native speakers. The second section presents early ERP studies supporting the CPH, discusses some of their methodological problems, and follows up with data from more recent studies avoiding these problems. It is concluded that well-controlled ERP studies support the convergence hypothesis, according to which L2 learners initially differ from native speakers and then converge on native-like neurocognitive processing mechanisms. The fact that ERPs in late L2 learners at high levels of proficiency are often indistinguishable from those of native speakers suggests that age-of-acquisition effects in SLA are not primarily driven by maturational constraints.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
