Abstract

fetched live from OpenAlex

The preschool years are a critical period of brain and language development, although little research has investigated relationships between language and brain structure or function during this age. This thesis contains an investigation of children aged 3.0-4.7 years who underwent assessments of phonological processing and speeded naming, measures that predict later reading ability. We used quantitative MRI methods to investigate brain structure and function, including diffusion tensor imaging, inhomogeneous magnetization transfer imaging, morphological analysis, and arterial spin labeling. Findings suggest that children with stronger language skills possess more mature patterns of brain structure and function. Our results are consistent with previous research in older children that suggest that structural and functional markers for reading disability exist before children begin formal reading instruction. Our results have identified neurological markers for children at risk for developing reading impairments, including reduced myelination, decreased cortical thickness, and reduced perfusion in the left hemisphere.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
