Randomized trial investigates cognitive states' effect on fall risk in high-altitude construction workers, suggesting age-specific interventions.

This research aims to determine how age affects cognitive states related to fall risk among construction workers at heights.
Investigated cognitive states through virtual reality scenarios and electroencephalogram data analysis
Examined variations in vigilance, mental fatigue, attention, task engagement, and anxiety between age groups
Conducted immersive simulations of high-altitude construction environments
Older workers exhibited lower vigilance and increased mental fatigue, with significant implications for safety
Younger workers showed heightened anxiety related to heights while having better vigilance
Mental fatigue was found to be the most significant cognitive state affecting older workers' fall risk, whereas height-related anxiety was more significant for younger workers.

Li et al. (2026) studied this question.
