Abstract
In recent years, the number of infant studies using functional Near-Infrared Spectroscopy (fNIRS) has been steadily increasing. One of the main focuses in developmental cognitive neuroscience research is uncovering the brain correlates of speech processing. This is a meta-analysis, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, investigating the brain regions activated when presented with speech during infancy. Specifically, we will report on the field-wide result of whether the frontal and temporal lobes of both or either hemispheres are active when neonate to 12-month-old infants perceive auditory or audiovisual stimuli in studies employing fNIRS methodologies.

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
