Comparing The Effects Of Traffic Speed And Driver Assistance On Different Age Groups: Mixed Methods User Testing, Alan Mintz

All Theses

Although much research exists investigating preferences towards transportation and driver assistance technologies, there is a gap in the literature related to taking a mixed methods approach investigating age-related differences in traffic management behaviors. Previous studies have established that older adults tend to avoid higher risk traffic situations more often than younger adults. This research builds on existing work that compares different aged participants simulated driving behaviors, self-reported workload, and interview responses. Benefits from this study include adding to our understanding of gap maintenance behavior, perceived workload at varying traffic speeds, and preferences among younger and older drivers towards offloading driving …

Identification And Validation Of A Measurement Of Emergency Physician Workload During End Of Shift Patient Handoffs, Steven Foster

All Dissertations

Recent increases in emergency physician (EP) workload have been identified as contributors to increased EP burnout, increased staff attrition, decreased patient safety, and increased patient admission rates. Patient handoffs have been extensively researched as critical points in patient care, with existing research primarily focusing on communication errors and interventions designed to standardize handoff communication protocols.

While end of shift handoffs in hospital emergency departments (EDs) intuitively represent a transfer of patient caseload from an outgoing EP to an incoming EP, there is a fundamental lack of literature examining how such handoffs contribute to EP workload, and a similar lack of …

The Effect Of Workload On Trust Repair: Testing A New Model Of Trust Repair, Jada Lester

All Theses

Given the importance of trust in human-automation interaction, there has been intense activity in understanding trust repair (Esterwood & Robert, 2021). However, despite the numerous trust repair studies, there is no coherent understanding of when and why trust repair works. A recently proposed theoretical model identified two unique categories of trust repair (central and peripheral) and the factors that might affect their success (Pak & Rovira, 2023). The current study tested a specific hypothesis arising from the theoretical model: variations in workload will affect central trust repair efficacy, but peripheral trust repair will be unaffected by workload. Participants engaged in …

Revisiting The Vigilance Taxonomy: Are Findings Consistent In A Remote Environment?, Grace E. Waldfogle

Graduate Thesis and Dissertation 2023-2024

Previous research has highlighted key taxonomic factors that have been found to influence human performance on vigilance tasks. However, previous literature has focused on research conducted in laboratory settings but has not examined vigilance tasks in remote environments. The present dissertation addresses this gap in the literature by examining human performance on a remote vigilance task, as well as workload and stress associated with the task. Qualitative data were collected to further understand the environment and distractions that participants experienced. Across three experiments, 372 participants were asked to complete a vigilance task and answer surveys pertaining to stress, workload, and …

Analisis Stres Kerja Pada Pengemudi Truk Pengantar Produk Pt Xyz Tahun 2022, Riska Oktaviana, Hendra Hendra

National Journal of Occupational Health and Safety

Drivers are one of the occupational groups with the highest risk of experiencing workplace stress. This can happen to truck drivers who play an important role in the PT XYZ product delivery process. This study aims to describe the work stress level in PT XYZ product delivery truck drivers and the risk factors associated with work stress. The factors studied include individual factors (age, marital status, place of residence, number of children, and length of service), psychosocial factors related to job context (job control, social support, and home-work interface), and job content (physical environment of the cabin, workload, and working …

Impact Of Electronic Flight Bag (Efb) On Single Pilot Performance And Workload, Saravanan Suppiah, Dahai Liu, Sang-A Lee, Andrew Dattel, Dennis Vincenzi Ph.D.

International Journal of Aviation, Aeronautics, and Aerospace

The increase of automation in the aviation industry poses challenges to human performance. To attest this point, studies about aircraft accidents reveal that pilots’ response to automated systems is not always coherent. Research findings suggest that pilots’ interaction with automated systems in highly demanding task situations results in an increase in workload, and if they are unable to resolve it in time, it will compromise flight safety. Therefore, in the interest to further explore the impact of automation on human factor constructs, the study aimed to investigate the impact of Electronic Flight Bag (EFB) on pilot workload. The study measured …

Human Performance In Manufacturing Tasks: Optimization And Assessment Of Required Workload And Capabilities, Maria Chiara Leva, Lorenzo Comberti, Micaela Demichela, Alberto Caimo

Conference papers

This paper discusses some examples where human performance and or human error prediction was achieved by using a modified version of the Rasch model(1980), where the probability of a specified outcome is modelled as a logistic function of the difference between the person capacity and item difficulty. The model needs to be modified to take into account an outcome that may not be dichotomous and o take into account the interaction between two macro factors: (a) Task complexity: that summarises all factors contributing to physical and mental workload requirements for execution of a given operative task & (b) Human capability: …

The Effect Of Improvisations And Observations On Standardized Patient Encounters, Subjective Workload And Stress, Elizabeth T. Newlin-Canzone

Psychology Theses & Dissertations

Standardized patients (SPs) are people trained to present a medical case for teaching and assessing medical students and they simultaneously perform several demanding tasks including portraying the patient, assessing the learner, and providing feedback. This study investigated the effect of improvisations and multiple task performance on the ability to observe another's nonverbal (NV) behaviors and rate their communication skills. Subjective reports of mental workload and stress were also obtained. The first study involved undergraduates interviewing for a job. Type of interview (rote and improvisational) and type of observation (passive and active) were manipulated within groups. Based on theories of attention …
