Abstract
Abstract Research investigating the contribution of bilingualism to cognitive reserve has produced mixed findings. Previous reviews and commentaries have explored potential reasons for the inconsistent findings across studies, including language status, participant characteristics, and immigration-related variables. This chapter addresses several questions that have received relatively less attention. Specifically, in this chapter we aim to clarify the relationship between brain function and structure within a reserve framework (including data from our lab examining regional cortical thickness in patients with mild cognitive impairment and Alzheimer’s disease). We also review the impact of bilingualism on memory functioning, and examine theoretical and practical issues (such as trajectory of change in cognitive function) surrounding the cognitive reserve hypothesis. We end by discussing the potential for -and practicalities of- using Big Data initiatives to contribute insight into the role of bilingualism in cognitive reserve and brain function.

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
