Development Of An Alternative Methodology For Implementation Of Sagat During Task Performance, Durant C. Bridges

International Symposium on Aviation Psychology - 2015

Situation awareness (SA) has been linked to performance in a variety of disciplines to date, but originated in the aviation arena. Situation awareness derives from attention and working memory being used toward acquiring and interpreting information from the environment (Endsley, 1995). The most revered objective method of measuring situation awareness is the Situation Awareness Global Assessment Technique (SAGAT). This technique employs random freezes of participant interfaces during simulations to query participants and assess the level of knowledge of what is happening at the time of the freezes. A discussion of applications using an alternative approach to SAGAT for operators in …

The Smart Cockpit Initiative, Kevin M. Smith, Stephane Larrieu

International Symposium on Aviation Psychology - 2015

Flight deck displays that automatically adapt themselves to changing operational conditions are referred to as mission adaptive displays, or smart cockpits. Most smart-enabling technology is already available in modern aircraft. To be operationally effective, however, mission adaptive displays should: • Present mission critical information when it is most urgently needed. • Be capable of responding to all mission critical events—single and multiple occurrences. • Depict a rising risk profile based upon risk defining criteria. • Utilize abstract clusters to reduce workload in high stress situations. • Contain, whenever appropriate, performance aids so that precise maneuver execution is assured.

A Comprehensive Effort To Arrive At An Optimally Reliable Human Factors Taxonomy, Raymond E. King

International Symposium on Aviation Psychology - 2015

Department of Defense (DoD) members sought to improve the inter-rater reliability of the DoD Human Factors Analysis and Classification System, (DoDHFACS). DoDHFACS differs from the original system developed by Wiegmann and Shappell (2003), based on the work of Reason (1990), by further analyzing mishaps and hazards to a more granular level – arriving at specific “nanocodes.” The steps involved in the effort included determining which of the 147 “nanocodes” were rarely/never used and collapsing nanocodes and rewriting definitions to arrive at 109 nanocodes. Next, a stepwise checklist to guide investigators through consideration of nanocodes was created. Student investigators were guided …

Recent Advances In Tactile Cueing, Angus H. Rupert, Ben D. Lawson

International Symposium on Aviation Psychology - 2015

Flight tests conducted by the Army and Navy have demonstrated the utility of the Tactile Situation Awareness System (TSAS) as an adjunct to visual instruments to improve pilot performance in degraded visual environments or under conditions of high workload. The tactile stimulators (tactors) used in each of the flight tests have been incorporated into aircraft components (seat cushions and shoulder straps) and a torso garment (belt or vest). Current tactors must operate at full magnitude and a very restricted frequency range (240 to 250 Hz) in order to provide consistent and perceptible stimuli in the aviation environment. Fortunately, recent developments …

Near-Future Technological Countermeasures For Spatial Disorientation In Flight, Eric M. Littman, Ben D. Lawson, J. Christopher Brill, Angus H. Rupert

International Symposium on Aviation Psychology - 2015

Spatial Disorientation (SD) is an important cause of deadly aircraft mishaps, despite improvements in night vision, head-up-displays, cockpit automation, etc. This paper explores several technological countermeasures for SD. This report begins by discussing the magnitude of the SD problem and the reasons why technological countermeasures are needed. The authors discuss the three main approaches that are typically used (improved selection, training, or technology) to decrease the incidence of SD, and argue that improved selection and training, although beneficial, are not sufficient by themselves to prevent SD. The authors introduce various technological solutions they are developing, including better models to predict …

Hiroshima And Mass Trauma Today: Treating Post-Traumatic Stress Disorder In Individuals And Communities, Ashley Martinez

International ResearchScape Journal

At 8:15 am on August 6^th, 1945, the world and the way in which we fight wars changed forever. Immediately following the drop of the Little Boy atomic bomb, the city of Hiroshima was decimated, leaving the surviving citizens to deal with poverty, starvation, loss of loved ones, and utter destruction of their lives. After the bombing, survivors were left with burns, radiation poisoning, and physical scars. Unknown to the survivors of the atomic bombings, or Hibakusha, were the ensuing psychological and emotional damages. In 2014, we know more about traumatic experiences than in 1945. Studies from …

Perceived Harms And Benefits Of Parental Cannabis Use, And Parents’ Reports Regarding Harm-Reduction Strategies, Kathleen J. Donoghue

Theses: Doctorates and Masters

This research focussed on families in which at least one parent was a long-term cannabis user; I explored family members’ perceptions of the benefits and harms of cannabis use and the strategies parents used to minimise cannabis-related harm to themselves and their children. In depth, semi-structured interviews were undertaken with 43 individuals from 13 families, producing a series of family case studies that enabled examination of multiple perspectives within each family. In Study 1, I used an interpretive framework guided by Miles and Huberman’s (1994) thematic content analysis technique to analyse interview data, while study 2 yielded detailed descriptive vignettes …

Life Balance – A Mindfulness-Based Mental Health Promotion Program: Conceptualization, Implementation, Compliance And User Satisfaction In A Field Setting, Lisa Lyssenko, Gerhard Müller, Nikolaus Kleindienst, Christian Schmal, Mathias Berger, Georg Eifert, Alexander Kölle, Siegmar Nesch, Jutta Ommer-Hohl, Michael Wenner, Martin Bohus

Psychology Faculty Articles and Research

Background

Mental health disorders account for a large percentage of the total burden of illness and constitute a major economic challenge in industrialized countries. Several prevention programs targeted at high-risk or sub-clinical populations have been shown to decrease risk, to increase quality of life, and to be cost-efficient. However, there is a paucity of primary preventive programs aimed at the general adult population. “Life Balance” is a program that employs strategies borrowed from well-established psychotherapeutic approaches, and has been made available to the public in one federal German state by a large health care insurance company. The data presented here …

Asthma-Related Anxiety And Quick-Relief Medication Use In Urban Children With Asthma, Sarah E. Astrab, Robin Everhart

Undergraduate Research Posters

Among children, asthma is the most common chronic illness. Although not curable, asthma is manageable with the use of both daily controller medication and quick relief or rescue medication. Anxiety has been found to increase asthma symptoms in children. Caregivers who are anxious about their child’s asthma symptoms may perceive their child’s asthma as more severe or doubt their ability to manage their child’s asthma, which can result in the misuse of asthma medication. This study focused on the association between asthma-related anxiety and the use of quick-relief asthma medications in a low-income, urban sample in Richmond, Virginia. Child participants …

Is Postpartum Depression A Disease Of Modern Civilization?, Jennifer Hahn-Holbrook, Martie Haselton

Psychology Faculty Articles and Research

Access to calorie-dense foods, medicine, and other comforts has made modern humans healthier than our prehistoric ancestors in many respects. However, the epidemics of obesity, diabetes, and cardiovascular disease suggest that there are also drawbacks to modern living. Here, we address the question of whether the dramatic cultural changes that have occurred over the past century have inflated rates of postpartum depression, adding postpartum depression to the list of diseases of modern civilization. We review evidence from cross-cultural, epidemiological, and experimental studies documenting associations between postpartum depression and modern patterns of early weaning, diets deficient in essential fatty acids, low …

On Reporting The Onset Of The Intention To Move, Uri Maoz, Liad Mudrik, Ram Rivlin, Ian Ross, Adam Mamelak, Gideon Yaffe

Psychology Faculty Books and Book Chapters

"In 1965, Hans Kornhuber and Luder Deecke made a discovery that greatly influenced the study of voluntary action. Using electroencephalography (EEG), they showed that when aligning some tens of trials to movement onset and averaging, a slowly decreasing electrical potential emerges over central regions of the brain. It starts 1 second ( s) or so before the onset of the voluntary action1 and continues until shortly after the action begins. They termed this the Bereitschaftspotential, or readiness potential (RP; Kornhuber & Deecke, 1965).2 This became the first well-established neural marker of voluntary action. In that, the RP allowed for more …

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …

Intentions And Voluntary Actions: Reframing The Problem, Aaron Schurger

Psychology Faculty Articles and Research

Nachev and Hacker are justified in drawing our attention to the importance of conceptual clarity and coherence as these are too often overshadowed by technical sophistication and methodological rigor, which by themselves count for little. But can a process of “conceptual analysis” actually help us to avoid pitfalls, or does it merely serve to expose those pitfalls in hindsight? What is needed is a method for making scientific arguments formulaic and laying bare the implicit assumptions. We have tools for this, but not everyone uses them.

Tapping To A Slow Tempo In The Presence Of Simple And Complex Musical Meters Reveals Experience-Specific Biases For Processing Music, Sangeeta Ullal-Gupta, Erin E. Hannon, Joel S. Snyder

Psychology Faculty Research

Musical meters vary considerably across cultures, yet relatively little is known about how culture-specific experience influences metrical processing. In Experiment 1, we compared American and Indian listeners' synchronous tapping to slow sequences. Inter-tone intervals contained silence or to-be-ignored rhythms that were designed to induce a simple meter (familiar to Americans and Indians) or a complex meter (familiar only to Indians). A subset of trials contained an abrupt switch from one rhythm to another to assess the disruptive effects of contradicting the initially implied meter. In the unfilled condition, both groups tapped earlier than the target and showed large tap-tone asynchronies …

Development Of A Short Version Of The Modified Yale Preoperative Anxiety Scale, Brooke N. Jenkins, Michelle Fortier, Sherrie H. Kaplan, Linda C. Mayes, Zeev N. Kain

Psychology Faculty Articles and Research

BACKGROUND: The modified Yale Preoperative Anxiety Scale (mYPAS) is the current “criterion standard” for assessing child anxiety during induction of anesthesia and has been used in >100 studies. This observational instrument covers 5 items and is typically administered at 4 perioperative time points. Application of this complex instrument in busy operating room (OR) settings, however, presents a challenge. In this investigation, we examined whether the instrument could be modified and made easier to use in OR settings.

METHODS: This study used qualitative methods, principal component analyses, Cronbach αs, and effect sizes to create the mYPAS-Short Form (mYPAS-SF) and reduce time …

Pregnancy Anxiety And Prenatal Cortisol Trajectories, Heidi S. Kane, Christine Dunkel Schetter, Laura M. Glynn, Calvin J. Hobel, Curt A. Sandman

Psychology Faculty Articles and Research

Pregnancy anxiety is a potent predictor of adverse birth and infant outcomes. The goal of the current study was to examine one potential mechanism whereby these effects may occur by testing associations between pregnancy anxiety and maternal salivary cortisol on 4 occasions during pregnancy in a sample of 448 women. Higher mean levels of pregnancy anxiety over the course of pregnancy predicted steeper increases in cortisol trajectories compared to lower pregnancy anxiety. Significant differences between cortisol trajectories emerged between 30 to 31 weeks of gestation. Results remained significant when adjusted for state anxiety and perceived stress. Neither changes in pregnancy …

If You Can’T Take The Heat, Stay Out Of The Kitchen: A Reflection On “Student Beliefs, Multiculturalism, And Client Welfare.”, Thomas G. Plante

Psychology

In Student beliefs, multiculturalism, and client welfare, Professor Kristin Hancock offers a thoughtful description of and reflection on the contemporary challenges associated with psychology graduate trainees managing their personal and religious beliefs and practices with the training and professional demands of the psychology profession and their educational training institutions. She reviewed several recent court cases (e.g., Ward v. Polite et al., Keeton v. Anderson-Wiley et al., Ward v. Wilbanks et al.) where psychology students sued their graduate programs (typically secular state universities) because their training requirements included multicultural competency training involving sexual issues such as homosexuality. These graduate training …

Relationship Between Sensory Sensitivities And Cognitive And Adaptive Abilities In Children With Autism Spectrum Disorders, Laura Pendergast

Honors Scholar Theses

Sensory sensitivities are widely reported among individuals with ASD. These sensory sensitivities can be classified as over-responsivity, under-responsivity, or seeking of sensory stimulation. Following recent changes in the diagnostic criteria, sensory sensitivities are considered a key feature of the behavioral phenotype of ASDs. Despite their significance, sensory sensitivities have been largely underestimated. Therefore, more research in this area may reveal important information about the influence of sensitivities on functioning, as well as the underlying causes of the symptoms. This study investigated a possible relationship between sensory sensitivities and cognitive and adaptive abilities in children with ASD. The sample included 29 …

Perceived Barriers To Obtaining Psychiatric Treatment At Johnson City Community Health Center, Mychal Bolton

Undergraduate Honors Theses

The purpose of this study was to describe the perceived barriers to obtaining psychiatric treatment at the Johnson City Community Health Center. The context of the study was a rural area in Eastern Tennessee. Five patients with confirmed DSM-IV mental health diagnoses were recruited during treatment and interviewed at the Johnson City Community Health Center after their scheduled appointments with a Mental Health Nurse Practitioner (MHNP). The semi-structured interview focused on perceived barriers to obtaining treatment, perceptions of treatment received, and perceived availability of treatment. From those interviews, two themes were identified and each of which had two sub-themes identified: …

An Animal Model Of The Motivational Symptoms Of Depression: Testing The Antidepressant Desipramine On An Effort-Related Choice Task, Samantha L. Collins

Honors Scholar Theses

Patients with depression, schizophrenia, and other related disorders often show effort-related motivational symptoms such as anergia, psychomotor slowing, lassitude, and fatigue. Several studies have indicated that dopamine (DA) within the nucleus accumbens (NAc) is involved in the regulation of effort-related behavior. Interference with NAc DA alters response allocation in effort related choice procedures, biasing animals towards the alterative that can be obtained with minimal effort. Previous studies have shown that administration of the vesicular monoamine transporter-2 (VMAT-2) inhibitor tetrabenazine (TBZ) shifts behavior in rats responding on the FR5/chow choice procedure causing a decrease in lever pressing and a compensatory increase …
