Prior research indicates that many warning symbols are poorly understood. However Lesch [Lesch, M.F., 2003. Comprehension and memory for warning symbols: Age-related differences and impact of training. J. Safety Res. 34, 495-505] found that accident scenarios could be used to improve comprehension of warning symbols. The current study further investigated(More)
This study compared the effectiveness of two different types of training in improving comprehension of warning symbols by younger (aged 20-35 years) and older adults (aged 50-70 years). The verbal label training paired the symbol with a label describing its meaning while the accident scenario training further expanded on the nature of the hazard, the(More)
PROBLEM Prior research indicates that many warning symbols are poorly understood, particularly by the elderly. METHOD The effectiveness of three different training conditions to improve comprehension and memory for warning symbols was assessed for younger (18-35 years of age) and older (50-67 years of age) participants. All three conditions paired the(More)
Many studies have documented the performance decrements associated with driver distractions; however, few have examined drivers' awareness of these distraction effects. The current study measured how well-calibrated drivers are with respect to performance decrements from distracting tasks. In this test track study, 40 younger and older drivers completed a(More)
Prior research has documented the manner in which a variety of driving performance measures are impacted by concurrent cell-phone use as well as the influence of age and gender of the driver. This current study examined the extent to which different driver groups are aware of their associated performance decrements. Subjects' confidence in dealing with(More)
OBJECTIVE This study examines the effect of a computer-based training module on drivers' attitudes and behaviors with respect to in-vehicle distraction. BACKGROUND Research findings on the negative performance implications of distraction call for the need to mitigate these adverse effects. METHOD Forty drivers (ages 18 to 20 yrs) were divided into two(More)
If walkers can anticipate surface conditions, they can adjust their gait to help reduce the risk of a slip. This study investigated visual cues to slipperiness. Thirty-one participants made visually based judgements about 37 different floor surfaces. These judgements included ratings of slipperiness, reflectiveness, texture, traction, light/dark, likelihood(More)
There is increasing momentum towards international harmonization of warning standards. Therefore, it is critical to determine the applicability of existing standards across different cultures. Perceived hazard in response to isolated warning components (colors, signal words and symbols) and warning configurations was examined as a function of culture of the(More)
As more devices and services are integrated into vehicles, drivers face new opportunities to perform additional tasks while driving. While many studies have explored the detrimental effects of varying task demands on driving performance, there has been little attention devoted to tasks that vary in terms of personal interest or investment-a quality we liken(More)
