Hazard perception (ability to identify dangerous road situations that require evasive action) declines with age and is linked to changes in visual attention and crash risk. Evidence shows that training can improve this ability in older adults. Yet, no study has considered the type of experience (manual versus automatic transmission) these older drivers have. The current study aims to fill this gap by examining the effects of age, experience and training on hazard perception ability. Twenty-four older and 23 middle aged adults (equal number of manual/automatic drivers per age group) were trained in a 20-minute single-session on hazard perception. Results indicate hazard performance declines with age and this is exacerbated with older automatic drivers. Further, the results show that generally training improves for most hazard variable. However, training does does assist older automatic drivers on identifying hazards.

ABSTRACTBackground: With the number of older drivers increasing, self-regulation of driving has been proposed as a viable means of balancing the autonomy of older adults against the sometimes competing demand of public safety. In this study, we investigate self-regulation of driving among a group of older adults with varying functional abilities.Method: Participants in the study comprised 1,543 drivers aged 75 years or older. They completed an objective measure of visual attention from which crash risk was estimated, and self-report measures of driving avoidance, driving exposure, physical functioning, general health status, and vision. Crash records were obtained from the State Department of Public Safety.Results: Overall, participants were most likely to avoid driving in bad weather followed by driving at night, driving on high traffic roads, driving in unfamiliar areas, and making left-hand turns across oncoming traffic. With the exception of driving at night, drivers at higher risk of crashes generally reported greater avoidance of these driving situations than lower risk drivers. However, across all driving situations a significant proportion of higher risk drivers did not restrict their driving. In general, self-regulation of driving did not result in reduced social engagement.Conclusion: Some older drivers with visual attention impairments do not restrict their driving in difficult situations. There is a need for physicians and family members to discuss driving behaviors with older adults routinely to ensure their safety. The association between visual attention and driving restriction also has implications for interventions aimed at preserving mobility in the elderly.

Abstract Older adults are at greater risk of death and serious injury in transportation crashes which have been increasing in older adult cohorts relative to younger cohorts. Can technology provide a safer road environment? Even if technology can mitigate crash risk, is it acceptable to older road users? We outline the results from several studies that tested 1) whether advanced driver assistance systems (ADAS) can improve older adult driving performance, 2) older adults’ acceptance of ADAS and Autonomous Vehicle (AV) systems, and 3) perceptions of value for ADAS systems, particularly for blind-spot detection systems. We found that collision avoidance warning systems improved older adult simulator driving performance, but not lane departure warning systems. In a young to middle-aged sample the factor “concern with AV” showed age effects with older drivers less favorable. Older drivers, however, valued an active blind spot detection system more than younger drivers.

This study investigated agency and communion attributes in adults’ spontaneous self-representations. The study sample consisted of 158 adults (80 men, 78 women) ranging in age from 20 to 88 years. Consistent with theorising, significant age and sex differences were found in terms of the number of agency and communion attributes. Young and middle-aged adults included significantly more agency attributes in their self-representations than older adults; men listed significantly more agency attributes than women. In contrast, older adults included significantly more communion attributes in their self-representations than young adults, and women listed significantly more communion attributes than men. Significant Age Group × Self-Portrait Display and Sex × Self-Portrait Display interactions were found for communion attributes, indicating that the importance of communion attributes differed across age groups and by sex. Correlational analyses showed significant associations of agency and communion attributes with personality traits and defence mechanisms. Communion attributes also showed significant correlations with four dimensions of psychological well-being.

Abstract Background Older drivers have a crash rate nearly equal to that of young drivers whose crash rate is the highest among all age groups. Contrast sensitivity impairment is common in older adults. The purpose of this study is to examine whether parameters from the photopic and mesopic contrast sensitivity functions (CSF) are associated with incident motor vehicle crash involvement by older drivers. Methods This study utilized data from older drivers (ages ≥60 years) who participated in the Strategic Highway Research Program Naturalistic Driving Study, a prospective, population-based study. At baseline participants underwent photopic and mesopic contrast sensitivity testing for targets from 1.5–18 cycles per degree. Model fitting generated area under the log CSF (AULCSF) and peak log sensitivity. Participant vehicles were instrumented with sensors that captured continuous driving data when the vehicle was operating (accelerometers, global positioning system, forward radar, 4-channel video). They participated for 1–2 years. Crashes were coded from the video and other data streams by trained analysts. Results The photopic analysis was based on 844 drivers, and the mesopic on 854 drivers. Photopic AULCSF and peak log contrast sensitivity were not associated with crash rate, whether defined as all crashes or at-fault crashes only (all p > 0.05). Mesopic AULCSF and peak log sensitivity were associated with an increased crash rate when considered for all crashes (rate ratio (RR): 1.36, 95% CI: 1.06–1.72; RR: 1.28, 95% CI: 1.01–1.63, respectively) and at-fault crashes only (RR: 1.50, 95% CI: 1.16–1.93; RR: 1.38, 95% CI: 1.07–1.78, respectively). Conclusions Results suggest that photopic contrast sensitivity testing may not help us understand future crash risk at the older-driver population level. Results highlight a previously unappreciated association between older adults’ mesopic contrast sensitivity deficits and crash involvement regardless of the time of day. Given the wide variability of light levels encountered in both day and night driving, mesopic vision tests, with their reliance on both cone and rod vision, may be a more comprehensive assessment of the visual system’s ability to process the roadway environment.

Abstract Attitudes towards aging include both positive and negative beliefs about older adults (Iverson et al., 2017; Palmore, 1999). Palmore’s (1998) Facts on Aging Quiz, a widely used assessment of knowledge about aging, also identifies common societal misconceptions about aging. Findings regarding age group differences in attitudes toward aging are mixed (Bodner et al., 2012; Cherry & Palmore, 2008; Rupp et al., 2005). The current study compared knowledge of aging, negative age bias, and positive age bias between young adults (18-35 years, n=268) and middle-aged adults (40-55 years; n=277). Middle-aged adults reported significantly greater average knowledge of aging than young adults (p=.019), although both groups had relatively low knowledge (MA: M=13.0, YA: M=12.2). Middle-aged adults also showed significantly less negative age bias (p<.001) and significantly more positive age bias than young adults (p=.026). Although the total sample was significantly more likely to be incorrect than correct on 23 of the 25 facts (p<.001), young adults were significantly more likely than middle-aged adults (p<.001) to respond incorrectly for only 2 of 25 facts. Both facts reflected greater negative age bias among young adults than middle-aged adults. These facts concerned older adults’ ability to work as effectively as young adults (fact 9) and frequency of depression in older adults (fact 13). Results demonstrate that age bias is not limited to young adults and may continue through midlife, though negative age bias in particular may be lower for individuals approaching older adulthood, which could have implications for their psychological and physical well-being.

Hazard perception in driving refers to a driver’s ability to anticipate potentially dangerous situations on the road ahead and has been the subject of research for over 50 years. It is typically measured using computer-based hazard-perception tests and has been associated with both retrospective and prospective crash risk, as well as key crash-risk factors such as distraction, fatigue, alcohol consumption, speed choice, and age-related declines. It can also differentiate high- and lower-risk driver groups. The problem is that it is also a skill that appears to take decades of driving experience to acquire. This raises the question of whether it is possible and practical to accelerate this learning process via assessment and training in order to improve traffic safety. We have evidence that, in contrast to most driver education and assessment interventions, hazard-perception testing and training appear to have the capability to reduce crash risk. For example, the inclusion of a hazard-perception test in the UK driver licensing process has been estimated to reduce drivers’ non-low-speed public-road crash rates by 11.3% in the year following their test.

OBJECTIVE: To estimate the prevalence of Brazilian older adults who drive a car/ride a motorcycle, according to sociodemographic characteristics. METHODS: This cross-sectional study uses data from the 2018 Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel). The prevalence of drivers was determined by an affirmative answer to the following question: “Do you drive a car, motorcycle and/or other vehicle?”. RESULTS: Among the 15,333 individuals aged 65 and over living in Brazilian capitals and the Federal District, the overall prevalence of drivers was 28.73% (95%CI 27.22 – 30.29) and was higher among men (53.37%; 95%CI 50.45 – 56.28), those with higher education (65.44%; 95%CI 61.98 – 68.75), and individuals aged 65 to 69 years (35.7%; 95%CI 33.06 – 38.61). Among the regions of Brazil, prevalence varied from 35% (Midwest and South) to approximately 22% (North and Northeast). Florianopolis (42.2%; 95%CI 38.05 – 46.47) and Palmas (40.32%; 95%CI 32.74 – 48.38) were the cities with the highest prevalence of older drivers. CONCLUSIONS: Characteristics such as sex, age group, region, and state capital of residence affect the prevalence of older drivers. Our results contribute to knowledge about how older adults choose to move around in large Brazilian cities, enabling proposal of strategies to improve the quality of this population’s displacement.

Abstract Research on attitudes toward dementia has often focused on younger and older adults; few studies have also included the age groups of established and middle adulthood. The current study utilized data from community-dwelling adults aged 18-95 (n=567) residing in two Midwestern states. Participants were divided into four age groups: emerging/young adulthood (ages 18-29), established adulthood (ages 30-45), middle adulthood (ages 46-64), and older adulthood (age 65+). ANOVA models were used to examine age group differences on the following outcomes: factual knowledge about dementia (total score on 14 true-false questions); attitudes toward dementia (total score on the 20-item Dementia Attitudes Scale); and a single item, “I am afraid of losing my memory” (rated on a 5-point scale). The effect of age group was significant in all models (p<0.01 for all). Emerging/young adults had significantly more knowledge about dementia, but less positive attitudes toward dementia, relative to established, middle-aged, and older adults. Attitudes and knowledge did not differ between established, middle-aged, and older adults. By contrast, older adults reported significantly more fear of memory loss than emerging/young, established, and middle-aged adults; fear did not differ between the latter three age groups. There were no significant interactions between age group and sex in any of the models. Implications of these findings are discussed.

Abstract Technology may assist older adults in improving their driving performance and therefore driving safety. However, it is sometimes a distraction and some older adults avoid its use due to the complexity of learning the systems. This study examined how older drivers interacted with an electronic navigation system (e.g., GPS) and the extent to which it impacted driving performance on unfamiliar routes. It also examined three approaches to training older adults how to program the devices. In Phase 1, 80 older drivers navigated unfamiliar routes using a GPS or paper directions and completed destination entry tasks. In Phase 2, 60 older drivers completed one of three training conditions (video, video with hands-on, placebo) to examine the impacts of training on destination entry performance. Driving performance was improved with GPS over paper directions (p = .025), as evaluated by a driver rehabilitation specialized on counterbalanced standardized routes. Analyses also showed significant effects for familiarity for use of GPS (p=.035) and age group (60’s versus 70’s) (p<.001), but many drivers had difficulty entering destinations. In Phase 2, a main effect of training was found (p=.02) with using video and one-on-one training showing the best performance. This study demonstrates older drivers could benefit from the use of such devices when driving to unfamiliar destinations, but training is needed with hands-on training with a live instructor being the best.
