“…These findings extended previous research, which has tended to focus more on age-related performance variability, such as with contrast sensitivity (Greene & Madden, 1987;Owsley, Sekuler, & Siemsen, 1983), useful field of view (Ball, Owsley, & Beard, 1990;Scialfa, Kline, & Lyman, 1987), stereopsis (Schieber, 1991), and overall attention capacity (Madden, 1986). However, in regards to 360-degree awareness, the study supported findings by Bao & Boyle (2009), who found older drivers to exhibit less usage of their review mirrors.…”

“…Bao & Boyle (2009), for example, found that middle-aged drivers checked their rearview mirror a significantly higher proportion of time than any age-group. However, they also observed differences between older and younger drivers during 'straight across' and 'left turning' manoeuvres, with the younger drivers being found to check their rearview mirror to a higher degree.…”

A study investigating the comparative situation awareness of older and younger drivers when driving a route with extended periods of cognitive taxation A study investigating the comparative Situation Awareness of older and younger drivers when driving a route with extended periods of cognitive taxation. Highlights• Younger drivers performed comparatively better than older drivers in Situation Awareness related scoring.• Perceptions of task difficulty appeared to be an important influential factor for SA proficiency.• Textual analysis of driver commentaries found that older drivers were less aware of what was behind their vehicles and enunciated less safety-related concepts. AbstractThis study sought to measure and compare the Situation Awareness (SA) of a younger group of 11 drivers (average age 28.2 years) to that of an older group of 10 drivers (average age 77.2 years), as they traversed a route that included many cognitively taxing elements. This was achieved by recording a participant's continual commentary of what s/he felt to be of relevance during the drive. These recordings were then transcribed and assessed by computer software capable of abstracting the main concepts from each individual's or group's narrative, and calculating scores indicative of Situation Awareness. It was found that the younger drivers scored significantly higher (p<0.024) than their older counterparts. Furthermore, when the results from the participants who undertook both this and previous studies in the series were compared (see Key et al., 2016), it was found that SA scoring could be importantly influenced by perceptions of a task's difficulty, rather than its actual difficulty. It was also indicative from the narratives, that the younger driving group had demonstrated a better 360-degree awareness, and enunciated more safety-related concepts.

“…Indeed, visual working memory, 37,38 the functional field of view 39,40 and exploratory eye movements [41][42][43] are all degraded in the elderly. Yet another interpretation holds that seniors rely for walking increasingly on foot vision, 44,45 which is typically blocked by visual non-walking task; however, this view is in conflict with the observation that seniors' deficits persist even if the visual non-walking task doesn't interfere with foot vision.…”

Role of motor skills and visual demand for age-related deficits in dual-task walking

Previous studies suggested that age-related deficits of walking are accentuated under dualtask conditions when the non-walking task is visually demanding. Here we evaluate whether a requirement for manual skills is critical as well. Young (22±2 years) and older (69±3 years) subjects walked along a straight path while performing a task that required manual skills but no visual processing, i.e., checking off boxes on a handheld panel without seeing the arm, or a task that required visual processing but no manual skill , i.e., a Stroop-like task with verbal responses. We found that the checking task affected the performance of young and elderly subjects to a similar degree, while the Stroop-like task affected seniors' performance more than that of young subjects. This outcome confirms the role of visual demand for age-related deficits of dual-task walking (in the Stroop-like task), but doesn't support a similar role for manual skills (in the checking task).

“…In psychological terms, eye movement measures include a glance, saccade, pupil diameter, fixation range and percentage of eye closure. According to Shan Boa's study on visual scanning at median-divided highway intersections in rural areas [19], visual scanning is classified into seven possible area of interest, (AOI) relative to a straight ahead position while driving. In this study, visual scanning was divided into six AOIs, as shown in figure 4.…”

Abstract:The objective of this study is to examine experience-related differences in microscope driving behavior as drivers performed six separate maneuvers, namely 1) driving on general urban roads, 2) approaching a tunnel portal, 3) driving through a tunnel's threshold zone, 4) driving in the interior tunnel zone, 5) driving in the zone ahead the tunnel exit and 6) driving after the tunnel exit. An on-road experiment was conducted with 20 drivers in two groups. The first group was made up of new licensed drivers, and the second group contained the more experienced drivers. The study consisted of one between-subject (experience) and five within-subject variables (drive environment type). The drivers' behavior was measured through Mean Glance Duration, AOI Attention Ration, Horizontal Eye Activity, Vertical Eye Activity, Percentage of Eyelid Closure, and Heart Rate Variability. With respect to the relevant psychological measures, the results show that in general more attention is focused on the far left-hand side of the road and the near front road when driving through tunnel areas when compared with driving on general roads. In addition, the psychological measurements indicate that tunnel's dark narrow environment causes anxiety on driving for lower heart rate variation coefficient (RRCV). New licensed drivers were more severely affected by the tunnel environment than the experienced drivers.
