A study is reported of the perception of visual surfaces in wire-frame stimuli generated by combinations of monocular surface contours and binocular disparity that provide differing information about 3-D relief. Observers vary considerably in the relative contribution made by the binocular and monocular cues to the perception of overall 3-D form. Without(More)
Neuroergonomics provides a multidisciplinary translational approach that merges elements of neuroscience, human factors, cognitive psychology, and ergonomics to study brain structure and function in everyday environments. Driving safety, particularly that of older drivers with cognitive impairments, is a fruitful application domain for neuroergonomics.(More)
Ecstasy (MDMA) use raises concerns because of its association with risky driving. We evaluated driving performance and risk taking in abstinent recreational MDMA users in a simulated car following task that required continuous attention and vigilance. Drivers were asked to follow two car lengths behind a lead vehicle (LV). Three sinusoids generated(More)
OBJECTIVES Typical measures of the useful field of view (UFOV) involve many components of attention. The objective of the current research was to examine the attentional operations that might underlie declines in the UFOV. METHOD AND RESULTS We used 2 basic attention tasks to characterize the profile of visual attention in UFOV-impaired and -unimpaired(More)
UNLABELLED BACKGROUND/STUDY CONTEXT: Typical measures for assessing the useful field (UFOV) of view involve many components of attention. The objective of the current experiment was to examine differences in visual search efficiency for older individuals with and without UFOV impairment. METHODS The authors used a computerized screening instrument to(More)
This study investigated how system failures influenced drivers' reliance on Adaptive Cruise Control (ACC). A medium-fidelity driving simulator was used to evaluate the effect of driving condition (traffic, rain) and automation (manual control, ACC) on headway maintenance and brake response. In conditions of rain, the signal continuity of the ACC sensors was(More)

Feeding distillers grains to cattle decreases shelf life stability of retail displayed steaks due to the increased polyunsaturated fatty acid (PUFAs) content. High levels of PUFAs cause rapid oxidation of the fats in meat. To improve shelf life, a low-fat distillers grain ration, without solubles (LFWDG; 4.72% fat), was compared to a traditional diet(More)
Older adults are overrepresented in fatal crashes on a per-mile basis. Those with useful field of view (UFOV) reductions show a particularly elevated crash risk that might be mitigated with vehicle-based warnings. To evaluate cross-modal cues that could be used in these warnings, we applied a variation of Posner's orienting of attention paradigm.(More)
Older drivers are at risk for vehicle crashes due to impairments of visual processing and attention, placing these drivers at greater risk in driving tasks that require continuous attention to neighboring traffic, especially lead vehicles (LVs). We investigated car following behavior in 42 younger drivers (ages 18 to 44 years) and 58 older drivers (ages 65(More)
