The effect of a simulated hearing loss on performance of an auditory memory task in driving

Abstract

Abstract:Hearing loss has been shown to exacerbate the effect of auditory distraction on driving 11 performance in older drivers. This study controlled for the potentially confounding factor of age-12 related cognitive decrements, by applying a simulated hearing loss in young, normally hearing removing capacity that could be used for other concurrent processes required for safe driving. 61The authors found that, compared to normally hearing participants, hearing impaired drivers An interesting, and unexpected, outcome of the Hickson et al. study (2010) was that hearing 72 impaired individual's driving performance (indexed by their composite driving score) was also

Does cognitive distraction improve or degrade lane keeping performance? Analysis of time-to-line crossing safety margins

“…Here, three difficulty levels of cognitive task were presented to drivers in a simulator study, and different measures of lane keeping performance were analyzed. In line with previous research (Cooper et al, 2013;Herbert et al, 2016;Jamson et al, 2005;), a lower SDLP was observed with concurrent cognitive load, in addition to an increase in steering reversal rate (at the 0.5 o level) and gaze concentration, with both measures showing a systematic change with increasing cognitive load.…”

“…SDLP during the 1-back task was only found to be lower than baseline (p=0.035). This finding shows that, in line with other studies, the cognitive load task causes a systematic reduction in lateral deviation, as measured by SDLP (Cooper et al, 2013;Herbert et al, 2016;Jamson et al, 2005;. SRR0.5 o : There was a significant main effect of task demands on SRR0.5 o (F(3, 93)=12.976, p<0.001, =0.295) , as shown in Fig.…”

“…To our knowledge, only a handful of studies have focussed specifically on examining TLC values during cognitive distraction, and when TLC results have been reported, these have generally been non-significant. For example, studies from the HASTE project (Carsten & Brookhuis, 2005) showed a significant effect of cognitive distraction for elderly drivers, with a significantly higher mean of TLC minima during engagement in low levels of cognitive distraction (compared to both baseline and moderate levels of cognitive distraction), but they failed to find a significant effect of cognitive distraction for average drivers, see also Östlund et al (2004);and Herbert et al (2016). Indeed, our calculations of mean TLC, minimum TLC, mean of TLC minima, and percentage of TLC less than 1s also failed to find any significant differences between baseline and task data, in the present study.…”
