Assessing the Mediating Roles of Global Sensory Impairment, Social Isolation, and Loneliness in the Association Between Education and Cognitive Function
Bibliographic record
Abstract
Education is a key predictor of cognitive function and dementia. Sensory impairments and social well-being are underexplored modifiable pathways through which education may influence cognitive function. Using longitudinal data from the National Social Life, Health, and Aging Project, we created a latent measure of global sensory impairment (GSI) encompassing all five "classical" senses. We estimated the indirect influence of education on Montreal Cognitive Assessment (MoCA) scores-our primary measure of cognitive function-through GSI, loneliness, and social isolation. Positive dementia screening was a secondary outcome. GSI accounted for 5.32% and social isolation for 3.79% of college attendance's influence on MoCA scores. For years of education, GSI accounted for 3.87% and social isolation for 2.85% of its influence on MoCA scores. Loneliness accounted for smaller percentages. Sensory impairments and social isolation may be targets for public health interventions aimed at reducing educational disparities in cognitive function and improving older adults' quality of life.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
