Abstract
In the last decade, the study of the cognitive advantages stemming from bilingualism has become a major focus of research in neuroscience. The evidence suggests that bilingualism may contribute to building cognitive reserve but controversies still remain. This paper provides evidence of the so-called “bilingual advantage” by focusing on neural and cognitive reserve. Specifically, we shall discuss (a) the rationale underlying the idea that bilingualism might provide a cognitive advantage particularly in agingand (b) the evidence for two types of reserve associated with bilingualism, namely neural and cognitive reserve. In particular, we will focus on evidence from recent functional neuroimaging studies on elderly bilinguals carried out by our research group and others.

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
