Effects Of Sleep On Intrusive Symptoms And Emotional Reactivity In A Laboratory-Based Film Analog Study, Anna Marie Thi Thanh Nguyen

Graduate Theses and Dissertations

Posttraumatic stress disorder (PTSD) is characterized by four symptom clusters. Recently, research highlights the need to focus on the impact of intrusive symptoms as a possible risk factor for the development and maintenance of PTSD. Cognitive and sleep models contribute to further understanding of intrusive symptoms. Recent work also highlights disgust as an emotion closely associated with the emergence of posttraumatic stress symptomology following traumatic events. This study used a film eliciting disgust in order to examine the effects of sleep on the intensity of intrusion symptoms and emotion reactivity. The sample consisted of 49 college students randomly assigned to …

Influence Of Cultural Similarities And Differences On Coworker Relationships And Perceived Levels Of Workplace Psychological Stress, Natalie Hidaka

Psychology | Senior Theses

In growing diversity, social interactions between cultures can build psychological strain. Although, people value familiarity in situations such as in the workplace. The more we seek identity economy in the workplace, the more cross-cultural collaboration becomes essential, yet challenging. To evaluate how cultural similarities and differences influence relationships at work, a voluntary survey was conducted including three sets of measurements; Coworker Relationship Scale, Perceived Stress Scale, and Self-Construal Scale. From 126 self-report, quantitative data showed that relationships between coworkers of different cultural backgrounds (DCB) had greater difficulties than those who share similar cultural backgrounds (SCB). Regardless of one’s psychological stress …

Cultural Influences On Exercise Type And Body Confidence In Women, Skye Sakashita, Desiree Crevecoeur-Macphail

Student Scholar Symposium Abstracts and Posters

This study examined cultural influences on exercise habits and body confidence in women, specifically between ethnic minority and white women. Past research has indicated that Asian women often feel more cultural pressure than their White counterparts. This study wanted to examine further and see if an individual’s parent being an immigrant differs in amount of cultural pressure. Another aspect that this survey examined is motivation for exercise. Past research found that women who felt greater dissatisfaction with their physical appearance were more likely to list factors such as appearance or weight as their reasoning for exercise rather than for health …

It’S Not All Aces: The Role Of Negative Parental Influences And Criminal Thinking In Juvenile Offending Behaviors, Branna Humphrey

Electronic Theses and Dissertations

The role of adverse childhood experiences (ACEs) and criminal thinking in causing criminal behavior has been explored extensively in criminal justice research. Based on the concepts of ACEs and the Psychological Inventory of Criminal Thinking Scale, the negative parental influences and criminal thinking styles of 1,354 juvenile offenders were examined to establish that negative parental influences and criminal thinking are separately associated with juvenile problem and offending behavior, and that criminal thinking mediates the relationship between negative parental influences and juvenile problem and offending behavior. Analyses showed support for criminal thinking as a pathway from negative parental influences to juvenile …

Social Media Usage And Self-Esteem Of College Students In Los Angeles Vs. Other American Cities, Emily Tortora

Global Tides

This study examines self-esteem levels of college students in accordance with their social media behaviors and residential cities. An online survey was used to compare Instagram behaviors and their Heatherton Self-Esteem scores between 51 college students from the Los Angeles area and 148 students from alternate American cities. It was hypothesized that college students from the Los Angeles area would report higher levels of social media activity and lower levels of self-esteem. Results did not show any significant trend in one’s residential location dictating social media behaviors, nor did one’s social media usage predict their levels of self-esteem. The study …

Everyday Memory In People With Down Syndrome, Yingying Jennifer Yang, Zachary M. Himmelberger, Trent Robinson, Megan Davis, Frances Conners, Edward Merrill

Department of Psychology Faculty Scholarship and Creative Works

Although memory functions in people with Down Syndrome (DS) have been studied extensively, how well people with DS remember things about everyday life is not well understood. In the current study, 31 adolescents/young adults with DS and 26 with intellectual disabilities (ID) of mixed etiology (not DS) participated. They completed an everyday memory questionnaire about personal facts and recent events (e.g., school name, breakfast). They also completed a standard laboratory task of verbal long-term memory (LTM) where they recalled a list of unrelated words over trials. Results did not indicate impaired everyday memory, but impaired verbal LTM, in people with …

Out With The Humans, In With The Machines?: Investigating The Behavioral And Psychological Effects Of Replacing Human Advisors With A Machine, Andrew Prahl, Lyn Van Swol

Human-Machine Communication

This study investigates the effects of task demonstrability and replacing a human advisor with a machine advisor. Outcome measures include advice-utilization (trust), the perception of advisors, and decision-maker emotions. Participants were randomly assigned to make a series of forecasts dealing with either humanitarian planning (low demonstrability) or management (high demonstrability). Participants received advice from either a machine advisor only, a human advisor only, or their advisor was replaced with the other type of advisor (human/machine) midway through the experiment. Decision-makers rated human advisors as more expert, more useful, and more similar. Perception effects were strongest when a human advisor was …

Developing A Predictive Model Of Depression And Suicidal Tendencies In Pilots, Tanya Kim Bulleigh

Doctoral Dissertations and Master's Theses

The mental health of commercial airline pilots is as important as their physical health because of their immense responsibility for the safety of their passengers and crews. Pilot suicides that end in fatal aircraft crashes result in many injuries and deaths. Although depression and suicidal tendencies are common across all genders, ages, ethnicities, and backgrounds, the mental health of aviation pilots has been challenging to evaluate and quantify through routine flight medical exams.

The purpose of this study was to determine predictive factors of depression and suicidal tendencies among commercial airline pilots. Previous research has determined predictive factors of depression …

Authentication Schemes' Impact On Working Memory, Janine D. Mator

Psychology Theses & Dissertations

Authentication is the process by which a computing system validates a user’s identity. Although this process is necessary for system security, users view authentication as a frequent disruption to their primary tasks. During this disruption, primary task information must be actively maintained in working memory. As a result, primary task information stored in working memory is at risk of being lost or corrupted while users authenticate. For over two decades, researchers have focused on developing more memorable passwords by replacing alphanumeric text with visual graphics (Biddle et al., 2012). However, very little attention has been given to the impact authentication …

Étude De L’Applicabilité De Haut-Parleurs Paramétriques Au Développement De Nouveaux Concepts D’Alarmes De Recul, Olivier Robin, Alain Berry, Hugues Nélisse

Rapports de recherche scientifique

L’utilisation d’alarmes de recul est obligatoire sur une majorité de véhicules lourds et reste un moyen largement utilisé pour prévenir et alerter les personnes œuvrant à proximité de ces véhicules. Des études antérieures, réalisées par l’IRSST, ont montré les limites d’efficacité des alarmes utilisées en milieu de travail pour minimiser le risque à la sécurité des travailleurs. De plus, les alarmes de recul, par le son de niveau élevé et très typé qu’elles produisent, sont régulièrement une source de nuisance importante pour les travailleurs, et aussi pour les riverains. Ces problèmes de gêne et de perception sonore pour les travailleurs …

Narrative Experiences Of Fathers Of Children With Down Syndrome, Corey Rose

Educational Studies Dissertations

This dissertation explores the narrative experiences of fathers raising children born with Down syndrome. The study joins a recent stratum of research on parents of children with Down syndrome which is grounded in critical disability theory, adheres to a social model of disabilities, and adopts narrative methodology, but which thus far has not investigated fathers’ experiences. 22 fathers, recruited by means of snowball sampling, participated in a two-question, semi-structured interview with a follow-up conversation. Findings from question one indicated that, in the initial moment of diagnosis, fathers experienced adverse encounters with medical personnel, intense negative emotions about the diagnosis, distressing …

Fatigue And Its Management In The Aviation Industry, With Special Reference To Pilots, Rajee Olaganathan, Timothy B. Holt, Jackie Luedtke, Brent D. Bowen

Publications

Abstract Fatigue is a significant contributing factor that reduces human ability and leads to accidents and threatens the safety of aircraft and human lives. Approximately 70% of fatal accidents that occur in commercial aviation operations are due to human factors. More specifically, crew fatigue contributes to nearly 15 to 20% of the accidents (Akerstedt, 2000). These accidents and incidents are associated with pilot fatigue because of the long duty periods, disruption of circadian rhythms, and inadequate sleep that are common among both commercial and military pilots. Though fatigue is seen in all the disciplines associated with the aviation industry, this …

Exploring Attentional And Emotional Biases As A Function Of Trauma And Dissociation Symptomology, Claudia Clinchard

Department of Psychology: Dissertations, Theses, and Student Research

There is evidence that threatening facial expressions (e.g., angry faces) direct attention toward the target, and that for facial expressions that are less threatening but still convey negative valence (e.g., fear faces) direct attention outward and to one’s environment, therefore causing a shift in memory performance and attentional bias depending on the level of threat in emotional facial expressions presented. Extant literature provides evidence for attentional biases both towards and away from threat in those with posttraumatic stress disorder (PTSD) symptomology. The current study aimed to replicate the previous findings of the effects stimulus and emotion have on memory performance …

An Investigation Of Factors That Influence Passengers’ Intentions To Use Biometric Technologies At Airports, Kabir Olaseni Kasim

The Effects Of Display Type, Weather Type, And Pilot Experience On Pilot Interpretation Of Weather Products, Jayde M. King, Beth Blickensderfer, Thomas A. Guinn, John L. Kleber, Thomas A. Guinn

Publications

The majority of general aviation (GA) accidents involving adverse weather result in fatalities. Considering the high weather-related fatality rate among GA flight operations, it is imperative to ensure that GA pilots of all experience levels can incorporate available weather information into their flight planning. In the past decade, weather product development has incorporated increasing levels of automation, which has led to the generation of high-resolution, model-based aviation displays such as graphical turbulence guidance and current icing potential, which rival the resolution of radar and satellite imagery. This is in stark contrast to the traditional polygonal-based displays of aviation weather hazards …
