Abstract

fetched live from OpenAlex

This research considers the efficacy of auditory alert systems for semi-autonomous vehicles from the perspective of the neurological processing of multi-modal information.While semiautonomous vehicles are growing in popularity, there is much to be discovered concerning driver safety.For example, understanding how the brain integrates multi-model information is essential to determining the efficacy of auditory alerting systems in semi-autonomous vehicles.The present work reports on how the auditory processing of deviant and standard stimuli is impacted by age and workload conditions at regions of the brain involved in the auditory processing pipeline.Electroencephalography (EEG) and behavioural data from five older (57-78) and five younger (18-26) participants were collected.Participants completed a visual memory task with low-and high-workload conditions along with a novel paired-click paradigm.Behavioural results showed the expected negative effects of age on visual task accuracy and response times.EEG results showed that in the low-workload visual task condition both younger and older adults partially overcame the redundancy effect of the second paired tone when a highly salient stimulus was presented.In contrast, P200 neural responses to these oddball tones were attenuated in older adults in the high-workload conditions of the visual memory task.These findings have implications for how alerting systems are implemented in semi-autonomous vehicles.

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.
