Horizontal Curve Negotiation In Drivers With And Without Autism Spectrum Disorder, Gabriela M. Sherrod
Horizontal Curve Negotiation In Drivers With And Without Autism Spectrum Disorder, Gabriela M. Sherrod
All ETDs from UAB
Negotiating horizontal curves is one of the more high-risk tactical control maneuvers when operating a motor vehicle, as drivers must simultaneously and adeptly control their steering adjustment, speed, and lane positioning, as well as accurately perceive the curvature of the road segment and adjust to proprioceptive cues. Given known differences in upper body motor control, coordination, proprioception, and attention, this maneuver may be particularly difficult for drivers with autism spectrum disorder (ASD). The current study examined how drivers with ASD negotiated rural horizontal curves. Thirty-one participants ages 16-30 (13 ASD, 18 TD) drove through a simulated driving environment containing one …
The Impact Of Time-To-Collision Estimates On Transportation Safety For Young Drivers With Developmental Disabilities, Austin M. Svancara
The Impact Of Time-To-Collision Estimates On Transportation Safety For Young Drivers With Developmental Disabilities, Austin M. Svancara
All ETDs from UAB
Motor vehicle collisions (MVC) are the leading cause of death for young drivers. MVC risk is higher among drivers with developmental disabilities, particularly individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Difficulties in time perception may negatively impact driving, such as with time-to-collision (TTC) estimations (i.e., an estimation of how long it will take to collide with another vehicle). The goal of this study was to determine whether individuals with ADHD and ASD displayed decrements in TTC estimations and whether perception of time in a general context was related to TTC estimations in a driving-specific context. A total …
Driving Through The Fog: The Impact Of Traumatic Brain Injury On Mental Fog And Driving Performance, Tyler Reed Bell
Driving Through The Fog: The Impact Of Traumatic Brain Injury On Mental Fog And Driving Performance, Tyler Reed Bell
All ETDs from UAB
Every year, millions of people in the United States sustain a traumatic brain injury (TBI). Subsequently, a subset of people with TBIs may incur roadway crashes due to poorer vehicle maneuvering and problems with higher-order driving skills such as speed control and lane maintenance. Research is needed to better understand what relates to driving aptitude following TBI. Previous research in individuals with TBI has focused on objective cognition, the set of mental abilities that help to process information for memory, planning, and action. TBIs can result in cognitive difficulties, which for some, may last months after mild cases and a …
Investigating Driving Performance In Older Adults: A Continuum Of Mild Cognitive Impairment, Tyler Preston Bull
Investigating Driving Performance In Older Adults: A Continuum Of Mild Cognitive Impairment, Tyler Preston Bull
All ETDs from UAB
Driving is an important instrumental activity of daily living (IADL) that is crucial for mobility and independence of adults in the United States. Dementia and cognitive impairment are indicated as increasing risk for driving impairment and cessation, prompting the necessity for screeners in predicting impaired driving performance. The Trails Making Test (TMT) A and B, and the Useful Field of View (UFOV) are common measures used to predict driving performance across populations of older adults. Prior research has shown that Mild Cognitive Impairment (MCI), which is theorized as an intermediary between normal aging and dementia, is associated with subtle declines …
A Comparison Of Novice And Experienced Drivers With Autism Spectrum Disorder, Haley Johnson Bishop
A Comparison Of Novice And Experienced Drivers With Autism Spectrum Disorder, Haley Johnson Bishop
All ETDs from UAB
According to recent estimates, only 33% of individuals with Autism Spectrum Disorder (ASD) successfully achieve licensure compared to nearly 84% of the general population. Despite this decreased number of individuals driving in the ASD population and the importance of driving in increasing independence and quality of life, research in transportation safety among drivers with ASD is limited. Many of the impairments associated with ASD such as anxiety, processing speed and executive function may negatively impact driving performance. This study is among the first to objectively assess possible demographic, cognitive and simulated driving performance differences in individuals with ASD who are …
Cognitive Correlates Of Driving Behavior In Older Adults With Hiv, Caitlin Northcutt Pope
Cognitive Correlates Of Driving Behavior In Older Adults With Hiv, Caitlin Northcutt Pope
All ETDs from UAB
Human immunodeficiency virus (HIV) currently affects over 1 million individuals in the United States. It is estimated that by the year 2020, up to 70% of individuals with HIV in the United States will be ages 50 and older, as these individuals live longer due to more advanced medicine and later diagnosis. Aging research suggests individuals with HIV may be at risk for accelerated or accentuated aging making age-related deficits, particularly with cognition and everyday functioning, of public concern. The current study investigated the complex associations between age, HIV disease state, cognition, health, and driving in 139 older adults (Mage …
Effect Of Vigilance On Driving Performance In Commercial Motor Vehicle Drivers, Ben Mcmanus
Effect Of Vigilance On Driving Performance In Commercial Motor Vehicle Drivers, Ben Mcmanus
All ETDs from UAB
Driving is a complex task requiring constant information processing made possible by attention. Because there are 5.7 million commercial motor vehicle (CMV) drivers in the United States, it is imperative to investigate factors affecting driving performance as well as methods to reduce motor vehicle collisions (MVCs) with the primary goal of eliminating transportation-related unintentional fatal and nonfatal injuries. Vigilance is a cognitive processing component that may play an important role in CMV driving safety. Two experiments were conducted to examine the effect of vigilance on simulated driving performance in varying conditions. Experiment 1 focused specifically on the effect of vigilance …
