Abstract

fetched live from OpenAlex

Hazard perception (ability to identify dangerous road situations that require evasive action) declines with age and is linked to changes in visual attention and crash risk. Evidence shows that training can improve this ability in older adults. Yet, no study has considered the type of experience (manual versus automatic transmission) these older drivers have. The current study aims to fill this gap by examining the effects of age, experience and training on hazard perception ability. Twenty-four older and 23 middle aged adults (equal number of manual/automatic drivers per age group) were trained in a 20-minute single-session on hazard perception. Results indicate hazard performance declines with age and this is exacerbated with older automatic drivers. Further, the results show that generally training improves for most hazard variable. However, training does does assist older automatic drivers on identifying hazards.

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.
