Neuroplasticity, neuroimaging, and bilingualism: Commentary on Baum and Titone
Bibliographic record
Abstract
In this comprehensive review by Baum and Titone, the authors promote the notion that bilingualism should be thought of as an agent of neuroplastic change over the life span. Their proposal offers a context within which to view early enrichment, one element of which is the early learning of two languages. The review points out the complexities of studying bilingualism and highlights empirical gaps in research that are critical to our understanding of how experience with language, especially exposure to two languages, might affect the neurocognitive system. The framework brings together disparate sets of studies in the literature across multiple methods, models, and disparate repertoires of descriptive terms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
