AB098. Perceptual, motor and cognitive factors related to braille reading performance in aging: a scoping review
Bibliographic record
Abstract
Background: A growing number of older adults with vision loss require vision rehabilitation services to address reading difficulties. Braille may be the most appropriate option for those with functional blindness, poor visual prognoses or dual sensory loss. While standardized braille assessment and training protocols are in place to guide interventions with children, there is a high degree of inconsistency and a lack of evidence-based knowledge about best practices to use with adults and seniors who require braille training. Age-related declines in tactile acuity, motor dexterity and cognition present unique barriers to braille training, but very little is known about the impact of aging on factors related to braille reading performance. The aim of this scoping review is to identify the perceptual, motor, and cognitive factors related to braille reading performance and to determine how these factors have been assessed or measured among blind adults and elderly individuals in prior studies. Methods: Using the scoping review method, a comprehensive search was conducted in three databases: PubMed, Educational Resource Information Center (ERIC), and the Cochrane library. Two reviewers screened articles for inclusion to ensure internal agreement, based on identified exclusion criteria. Results: The initial search resulted in 1,565 qualitative and quantitative articles. The results synthesize the perceptual, motor and cognitive factors known to predict braille reading performance, how these variables are impacted by the aging process, and how they have been measured in prior studies. Conclusions: This scoping review is the first step in working towards the development of evidence-based assessment and training protocols to standardized practice with adult and senior clients who require braille training. It also serves to clarify where current knowledge gaps exist in order to guide future studies on braille reading and aging.

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.
