The Physiological & Psychological Effects Of Sleep Deprivation, Nilson Aguilar

Nebraska College Preparatory Academy: Senior Capstone Projects

Sleep deprivation is a serious issue that affects this nation as a whole and is sadly ignored, overlooked, and even dismissed. Through extensive research one could see that sleep deprivation causes several unwanted health issues: some of which include obesity, insomnia, and anxiety. From this research conducted over the physical and psychological effects of sleep deprivation one can conclude that with simple education over this serious topic the effects of sleep deprivation would in fact significantly decrease. This in turn would benefit several people, families, and even society as a whole.

From the research conducted one can see that as …

Buying Happiness: Property, Acquisition, And Subjective Well-Being, David Fagundes

Faculty Articles

Acquiring property is a central part of the modern American vision of the good life. The assumption that accruing more land or chattels will make us better off is so central to the contemporary preoccupation with acquisition that it typically goes without saying. Yet an increasing body of evidence from psychologists and economists who study hedonics—the science of happiness—yields the surprising conclusion that getting and having property does not actually increase our subjective well-being. In fact, it might even decrease it. While scholars have integrated the insights of hedonics into other areas of law, no scholarship has yet done so …

Trial 1 Versus Trial 2 Of The Test Of Memory Malingering: Evaluating Accuracy Without A “Gold Standard”, Douglas Mossman, Dustin B. Wygant, Roger O. Gervais, Kathleen J. Hart

EKU Faculty and Staff Scholarship

This study examines the accuracy of the Test of Memory Malingering (TOMM), a frequently administered measure for evaluating effort during neurocognitive testing. In the last few years, several authors have suggested that the initial recognition trial of the TOMM (Trial 1) might be a more useful index for detecting feigned or exaggerated impairment than Trial 2, which is the source for inference recommended by the original instruction manual (Tombaugh, 1996). We used latent class modeling (LCM) implemented in a Bayesian framework to evaluate archival Trial 1 and Trial 2 data collected from 1198 adults who had undergone outpatient forensic evaluations. …

Role Of Food Preoccupation And Current Dieting In The Associations Of Parental Feeding Practices To Emotional Eating In Young Adults: A Moderated Mediation Study, Natalie A. Williams, Dipti A. Dev, Maren Hankey, Kimberly A. Blitch

Department of Child, Youth, and Family Studies: Faculty Publications

Parental feeding practices reflecting coercive control are related to children’s later eating behaviors, but the mechanisms underlying these effects remain poorly understood. This study examined the relationships between recalled childhood experiences of parental pressure to eat and restriction and current food preoccupation, dieting, and emotional eating in a racially diverse sample of college students (N = 711). Results revealed that parental restriction, but not pressure to eat, was associated with more emotional eating (r = 0.18, p < 0.0001). Food preoccupation mediated the association between restriction and emotional eating (95% CI [3.6495–7.2231]); however, a moderated mediation model revealed that the strength of the indirect effect of restrictive feeding on emotional eating through food preoccupation was significantly different for dieters and non-dieters (index of moderated mediation = 1.79, Boot SE = 0.79; 95% bias-corrected bootstrap CI [–3.5490 to –0.4515]). These findings provide unique insight into the mechanisms linking parental feeding practices with emotional eating in young adulthood. Future studies attempting to clarify the processes through which child feeding practices impact later eating behaviors should consider the role of current dieting.

Non-Medical Use Of Prescription Drugs, Stress, Cultural Orientation, Utilization Of Healthcare, And Protective Factors Among College Students In China, Cheuk Chi Tam

Theses and Dissertations

Background: Non-medical use of prescription drugs (NMUPD) refers to the use of prescription drugs which are traditionally utilized to manage pain or treat psychiatric problems but without a doctor’s prescription. In 2010, an investigation by the Substance Use and Mental Health Services Administration (SAMHSA) revealed that 5.3% of young adults (18 to 25-year-olds) in the United States reported past-month NMUPD. NMUPD has become a growing concern owing to associations with consequences such as college dropout, poor academic achievement, and health jeopardizing behaviors. College students' NMUPD has been well documented in the United States. Limited studies, however, have been conducted among …

Distress And Worry As Mediators In The Relationship Between Psychosocial Risks And Upper Body Musculosketal Complaints In Highly Automated Manufacturing, Fiona Wixted, Leonard O'Sullivan

H-Workload 2017: Models and Applications (Works in Progress)

As a result of an upward trend in automation, the requirement for supervisory monitoring and consequently, cognitive demand has increased in automated manufacturing. The incidence of musculoskeletal disorders has also increased in the manufacturing sector. A model was developed based on survey data to test if distress and worry mediate the relationship between psychosocial factors (job control, cognitive demand, social isolation and skill discretion), stress states and upper body musculoskeletal complaints in highly automated manufacturing companies (n=235). Cognitive demand was shown to be related to higher distress in employees. The data raise the question about the link between job control …

Petrochemical Plant Console Operator Workload:The Issues, David A. Strobhar

H-Workload 2017: Models and Applications (Works in Progress)

The console operators of certain petrochemical processes must maintain high levels of performance during process upsets or endanger personnel safety and the environment. Mismanagement of an upset can result in explosions, fires, and the release of hazardous chemicals to the environment. The change in workload from steady state to upset operation is significant, with alarms and control changes that are of an order of magnitude. This paper describes the state of console activity in process plants, particularly the increase with key upsets. Quantitative data on the nature of the console operator’s position, its workload during normal operation, and the requirements …

Towards A Continuous Assessment Of Cognitive Workload For Smartphone Multitasking Users, Angel Jimenez-Molina, Hernan Lira

H-Workload 2017: Models and Applications (Works in Progress)

The intermeshing of Smartphone interactions and daily activities depletes the availability of cognitive resources. This excessive demand may lead to several undesirable cognitive states, which can be avoided by continuously assessing the user cognitive workload. Recently, many attempts have emerged to assess this workload by using psycho physiological signals. This paper provides evidence that it is possible to train models that accurately identify in short time windows such cognitive workload by processing heart rate and blood oxygen saturation signals. This assessment could be applied in Smartphone notification delivery, interface adaptations or cognitive capabilities evaluation.

A Workload-Centered Perspective On Reduced Crew Operations In Commercial Aviation, Daniela Schmid

H-Workload 2017: Models and Applications (Works in Progress)

Mental workload of a pilot, in short workload, depends on various characteristics of different accumulated tasks on the flight deck. Exogenous task demands and endogenous supply of attentional or information processing resources determine workload [1]. Performance is expect to drop if the demand exceeds the available resources of the pilot. Expertise and experience modulate the endogenous sup- ply of resources like perceiving, updating memory, planing, making a decision, and executing and processing a response. Subsequently, workload manifests in performance variables, subjective experience, and physiological parameters [2]. This is how we can summarize workload very brie y to introduce a model …

Moving Between Automated And Manual Driving: Mental Workload And Performance Implications, Totsapon Butmee, Terry C. Lansdown

H-Workload 2017: Models and Applications (Works in Progress)

Automated driving has been predicted to take-over from manual vehicle control in the near future. The driver’s role may then change from active operator to passive observer. Such technology offers the tantalising promise of improving driving safety. However, many studies have presented findings suggesting potentially adverse effects from automated driving systems, e.g., reduced situation awareness. Mental workload is also a key issue of concern for researchers in this area. Excessive mental workload has repeatedly been shown to be associated with degraded driving performance. Previously, most traffic psychology studies on mental workload have focused the manual driving task. However, a shift …

Reducing Peak Workload In The Cockpit: A Human In The Loop Simulation Evaluating New Runway Selection Tool, Tanja Bos, Rolf Zon, Wilfred Rouwhorst

H-Workload 2017: Models and Applications (Works in Progress)

In efforts to increase safety and reduce peak workload situations in the cockpit, a tool with a different interaction style was developed for use in case of a runway change instructed by Air Traffic Control during approach. In an experiment a workload comparison was made between the new tool and the conventional cockpit. Workload was measured by means of a self-rating after each experiment run, as well as eye blink frequency during each run. Results show that the self-rated workload decreases with the new tool for one of the two crew members and the blink frequency suggests a workload decrease …

Facing Human Workload: The Resilient Ego: A Psychoanalytic Point Of View, Glauco Maria Genga, Maria Gabriella Pediconii

H-Workload 2017: Models and Applications (Works in Progress)

The paper aims to show new connections among Human Factors, Human Workload and Resilience. We intend: 1) to highlight the role of subject in facing the human workload, inflected as demanding tasks and emergency situations; 2) to show how psychoanalysis can provide novel insights, not only into human errors, but also into human resilience. They have a common denominator, at least in part: the role of subjective contributions even in demanding situations. Human workload includes a work for satisfaction. We recall also the case study of US Airways Flight 1549 water landing (the so called “Miracle on the Hudson”), which …

System Identification Of Motion Artifact: Noise In Eeg Headsets From Locomotion, Kaela Shea, James Tung

H-Workload 2017: Models and Applications (Works in Progress)

Fall prevention for geriatric populations is a growing concern among clinicians and researchers due to severe risk of morbidity and loss of independence. Emerging evidence has demonstrated that mental workload while walking influences gait stability and the risk for falling. Electroencephalography (EEG) presents a potential method to provide objective measures of mental workload, particularly during daily activities. Noise introduced to the EEG signal during motion, however, is restrictive. The study presented in the following paper isolates EEG signal noise attained from gait for a commercially accessible EEG system, the "Emotiv" Time and spectral system identification techniques were applied to model …

Online Measuring Of Available Resources, Enrique Munoz-De-Escalona, José Juan Canas

H-Workload 2017: Models and Applications (Works in Progress)

This paper present a proposal for measuring available mental resources during the accomplishment of a task. Our proposal consists in measuring emotions provoked by perceived self-efficacy in the execution of the task. Self-efficacy is one of the most important factors that affect the resources that a person puts at the disposal of the execution of the task. When a person perceives that he/she is not being effective he/she will activate more resources to improve his performance. This self-efficacy will be reflected in the emotions that the person experiences. A good efficacy will provoke positive emotions and a bad efficacy negative …

On The Overlap Of Vital Exhaustion And Depression, Bianchi Renzo, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Our reexamination of the symptoms and main measure of vital exhasution (VE) suggests that the overlap of VE with depression has been problematically underestimated due to inconsistent comparisons and blindness to definitional similarities. In our view, the case of VE is emblematic of a trend toward construct proliferation. Many ‘‘new’’ constructs are introduced in the literature precipitously, with insufficient examination of their added value, and based on ‘‘linguistic contortions’’ and anecdotal evidence rather than robust empirical findings and sound theorizing. Such constructs are often ‘‘distinguished’’ from existing ones on the basis of specious arguments and missing-the-point conclusions. This is for …

How Burroughs Plays With The Brain, Or Ritornellos As A Means To Produce Déjà-Vu, Antonio José Bonome

CLCWeb: Comparative Literature and Culture

In his article "How Burroughs Plays with the Brain, or Ritornellos as a Means to Produce Déjà-Vu" Antonio José Bonome discusses how the recurrence and significance of one of William S. Burroughs's most potent refrains, "dim jerky faraway," was inspired by its source text, Paul Bowles's second novel Let It Come Down (1952), where Tangiers-Interzone fuels the unwholesome descent of a US-American expatriate not unlike Bowles or Burroughs himself. "Dim jerky faraway" was used by Burroughs during more than two decades in different contexts, and its textual variations have sparked a mélange of colors, sounds, smells, and feelings oscillating in …

Now Hear This: Inattentional Deafness Depends On Task Relatedness, Donald J. Tellinghuisen, Alexander J. Cohen, Natalie J. Cooper

University Faculty Publications and Creative Works

Mixed results have been found for the impact of auditory information presented during high-perceptual-load visual search tasks, with some studies showing large effects and others indicating inattentional deafness, with such stimuli going largely undetected. In three experiments, we demonstrated that task relatedness is a key factor in whether extraneous auditory stimuli impact high-load visual searches. Experiment 1 addressed a methodological concern (e.g., Lavie Trends in Cognitive Sciences, 9, 75–82, 2005) regarding the timing of the relative onsets and offsets of task-related, to-be-ignored auditory stimuli and visual search arrays in experiments that have shown auditory distractor effects. Robust auditory distractor effects …

Naïve Beliefs About The Natural World In A Case Of Childhood Onset Amnesia, William Winter

Publications and Research

The individual profiled here (M.S.) suffered an episode of severe oxygen deprivation (anoxia) at the age of eight, damaging memory relevant structures in the mid-temporal lobes, including the hippocampus bilaterally. The resulting anterograde amnesia was characterized by profound deficits in autobiographical memory, but also a compromised ability to acquire new facts and information (semantic memory), resulting in the formation of idiosyncratic and naïve beliefs about the natural world that have persisted into his adult years. This article presents an interview with M.S. in which many of these idiosyncratic beliefs are detailed, and argues that they can be broadly viewed as …
