Measuring drivers' glare sensitivity: Evaluation of an automated technique

Abstract

An automated glare sensitivity-testing procedure based on contrast discrimination under variable glare was examined in a partially hierarchical experiment with 13 male and 17 female Ss comprising 3 homogeneously aged groups of 10 Ss each (mean ages 17, 42.2, and 69 yrs). ANOVA indicated significant differences between age groups and a small but significant practice effect. Correlations between successive test scores varied from .92 to .80, and the difference between mean scores of the oldest and youngest groups closely approximated that found in an earlier, clinical study. The technique is considered sufficiently accurate for quantifying glare sensitivity and identifying individuals who possess elevated glare sensitivity. Issues to be addressed in the future development of minimum standards for night driving are enumerated. (10 ref) (PsycInfo Database Record (c) 2025 APA, all rights reserved)
