The Psychomotor Vigilance Test: Sources Of State And Trait Variance, Hans-Juergen Hoermann

International Symposium on Aviation Psychology - 2013

Within the context of pilot and air traffic controller selection tests the Psychomotor Vigilance Test (PVT, Dinges & Powell, 1985) was evaluated for its underlying sources of variance. The PVT is a simple visual reaction time task, which is well established as a measure of alertness during sustained operations. It provides scores for mean reaction times and number of lapses. While the PVT has proven sensitivity for temporary states of fatigue and other stressors in withinsubjects designs, validation studies are lacking to examine it for potential sources of trait variance, which could lead to confounding effects. This paper presents results …

Controller – Pilot Communications In The Presence Of Asynchronous Uas Radar Surveillance Data, Xiaochen Yuan, Jonathan Histon, Catherine Burns, Steven Waslander, Reza Dizaji

International Symposium on Aviation Psychology - 2013

Integrating Unmanned Aircraft Systems (UAS) into controlled airspace will create challenges for the pilots and controllers who need information about the UAS. This paper presents a preliminary study of the effect of differential time delays, or asynchrony, in the distribution of UAS surveillance information to controllers and pilots. Effects on controller-pilot communication were observed through 6 distinct measures of both objective performance and subjective self-evaluation. Larger time delays had an observable impact on all of the observed measures; comparison of pilot and controller results showed that the operator with the most updated information consistently experiences less frustration and feels the …

Flight Deck Audio Displays: Striking The Right Tone In Future Designs, Mitchell L. Serber

International Symposium on Aviation Psychology - 2013

The 2009 accident involving Air France Flight 447 illustrates the gap between visual and auditory display design and implementation in commercial aircraft. By examining the successful evolution of Enhanced Ground Proximity Warning System (EGPWS) and Traffic Alert and Collision Avoidance System (TCAS) to incorporate both audio and visual alerting and resolution guidance to flight crews, a contrast is drawn with similar aids available in advance of aircraft upset episodes. A universal approach for future design should incorporate harmonized video and audio displays providing optimized alerting and guidance along with the latest in simulator training designed to emphasize aircraft state awareness …

Individual Differences In Perception And Performance Of Advanced Navigation Systems, Andre Garcia, Jesse Eisert, John Payne, Carryl L. Baldwin, Victor Finomore

International Symposium on Aviation Psychology - 2013

We examined individual differences in use and preference for tactile route guidance formats. Participants drove a simulated vehicle through counterbalanced pairings of four distinct cities using one of four navigation systems (three tactile and one auditory control). One tactile system used only pulse rate, the second system used only tactor location, and the third used both pulse rate and location to convey guidance instructions. All navigation systems provided both a preliminary and an immediate cue indicating to take the next most immediate turn. Individual differences in sense of direction resulted in different preference ratings without any observed performance differences. The …

The Impact Of Cognitive Psychology In Minimizing Human Errors, Patrik Jonzon

International Symposium on Aviation Psychology - 2013

Working towards zero accidents – Experience from education and supervision of pilots and air traffic controllers (ATC) from the Royal Danish Air Force gives us a model on how to apply the latest clinical psychology methods and research, and combine it with Human Factor models.

What is behind accidents? Errors, so can you talk about zero errors? Everyone knows that this is utopia; the question is rather how we can understand errors, minimize errors and minimize the effect of errors. The goal of this paper is to contribute to a theoretical and practical understanding of how to use the research …

Psychologists And Medications In The Era Of Interprofessional Care: Collaboration Is Less Problematic And Costly Than Prescribing, William N. Robiner, Tim R. Tumlin, Tanya Tompkins

Faculty Publications

Increasing emphasis on interprofessionalism and teamwork in healthcare renders psychologists’ collaborations critical and invites reexamination of psychologists’ roles related to medications. The Collaboration Level outlined by the APA’s Ad Hoc Task Force is more achievable and in synch with health reform than prescription privileges (RxP). RxP remains controversial due to training and safety concerns, lacking support from health professionals, psychologists, and consumers. Differences in educational preparation of psychologists relative to prescribing professionals are discussed. Enactment of only three of 170 RxP initiatives reveals RxP to be a costly, ineffectual agenda. Alternatives (e.g., integrated care, collaboration, telehealth) increase access without risks …

Association Study Of 167 Candidate Genes For Schizophrenia Selected By A Multi-Domain Evidence-Based Prioritization Algorithm And Neurodevelopmental Hypothesis, Zhongming Zhao, Bradley T.

Integrating evidence from multiple domains is useful in prioritizing disease candidate genes for subsequent testing. We ranked all known human genes (n = 3819) under linkage peaks in the Irish Study of High-Density Schizophrenia Families using three different evidence domains: 1) a meta-analysis of microarray gene expression results using the Stanley Brain collection, 2) a schizophrenia protein-protein interaction network, and 3) a systematic literature search. Each gene was assigned a domain-specific p-value and ranked after evaluating the evidence within each domain. For comparison to this ranking process, a large-scale candidate gene hypothesis was also tested by including genes with Gene …

Suicidal Risk Factors Of Recurrent Major Depression In Han Chinese Women, Yuzhang Zhu, Hongni Zhang, Shenxun Shi, Jingfang Gao, Youhui Li, Ming Tao, Kerang Zhang, Xumei Wang, Chengge Gao, Lijun Yang, Kan Li, Jiangguo Shi, Gang Wang, Lanfen Liu, Jinbei Zhang, Bo Du, Guoqing Jiang, Jianhua Shen, Zhen Zhang, Wei Liang, Jing Sun, Jian Hu, Tiebang Liu, Xueyi Wang, Guodong Miao, Huaqing Meng, Yi Li, Chunmei Hu, Yi Li, Guoping Huang, Gongying Li, Baowei Ha, Hong Deng, Qiyi Mei, Hui Zhong, Shugui Gao, Hong Sang, Yutang Zhang, Xiang Fang, Fengyu Yu, Donglin Yang, Tieqiao Liu, Yunchun Chen, Xiaohong Hong, Wenyuan Wu, Guibing Chen, Min Cai, Yan Song, Jiyang Pan, Jicheng Dong, Runde Pan, Wei Zhang, Zhenming Shen, Zhengrong Liu, Danhua Gu, Xiaoping Wang, Xiaojuan Liu, Qiwen Zhang, Yihan Li, Yiping Chen, Kenneth S.

The relationship between suicidality and major depression is complex. Socio- demography, clinical features, comorbidity, clinical symptoms, and stressful life events are important factors influencing suicide in major depression, but these are not well defined. Thus, the aim of the present study was to assess the associations between the above-mentioned factors and suicide ideation, suicide plan, and suicide attempt in 6008 Han Chinese women with recurrent major depression (MD). Patients with any suicidality had significantly more MD symptoms, a significantly greater number of stressful life events, a positive family history of MD, a greater number of episodes, a significant experience of …

Association Testing Strategy For Data From Dense Marker Panels, Donghyung Lee, Silviu-Alin Bacanu

Psychiatry Publications

Genome wide association studies have been usually analyzed in a univariate manner. The commonly used univariate tests have one degree of freedom and assume an additive mode of inheritance. The experiment-wise significance of these univariate statistics is obtained by adjusting for multiple testing. Next generation sequencing studies, which assay 10-20 million variants, are beginning to come online. For these studies, the strategy of additive univariate testing and multiple testing adjustment is likely to result in a loss of power due to (1) the substantial multiple testing burden and (2) the possibility of a non-additive causal mode of inheritance. To reduce …

Clinical Features Of Patients With Dysthymia In A Large Cohort Of Han Chinese Women With Recurrent Major Depression, Wenqing Wu, Zhoubing Wang, Yan Wei, Guanghua Zhang, Shenxun Shi, Jingfang Gao, Youhui Li, Ming Tao, Kerang Zhang, Xumei Wang, Chengge Gao, Lijun Yang, Kan Li, Jianguo Shi, Gang Wang, Lanfen Liu, Jinbei Zhang, Bo Du, Guoqing Jiang, Jianhua Shen, Ying Liu, Wei Liang, Jing Sun, Jian Hu, Tiebang Liu, Xueyi Wang, Guodong Miao, Huaqing Meng, Yi Li, Guoping Huang, Gongying Li, Baowei Ha, Hong Deng, Qiyi Mei, Hui Zhong, Shugui Gao, Hong Sang, Yutang Zhang, Xiang Fang, Fengyu Yu, Donglin Yang, Tieqiao Liu, Yunchun Chen, Xiaohong Hong, Wenyuan Wu, Guibing Chen, Min Cai, Yan Song, Jiyang Pan, Jicheng Dong, Runde Pan, Wei Zhang, Zhenming Shen, Zhengrong Liu, Danhua Gu, Xiaoping Wang, Xiaojuan Liu, Qiwen Zhang, Yihan Li, Yiping Chen, Kenneth S.

Psychiatry Publications

Background

Dysthymia is a form of chronic mild depression that has a complex relationship with major depressive disorder (MDD). Here we investigate the role of environmental risk factors, including stressful life events and parenting style, in patients with both MDD and dysthymia. We ask whether these risk factors act in the same way in MDD with and without dysthymia.

Results

We examined the clinical features in 5,950 Han Chinese women with MDD between 30–60 years of age across China. We confirmed earlier results by replicating prior analyses in 3,950 new MDD cases. There were no significant differences between the two …

A Quantitative Link Between Face Discrimination Deficits And Neuronal Selectivity For Faces In Autism, Xiong Jiang, Angela Bollich, Patrick Cox, Eric Hyder, Joette James, Saqib Ali Gowani, Nouchine Hadjikhani, Volker Blanz, Dara S. Manoach, Jason J.S. Barton, William D. Gaillard, Maximilian Reisenhuber

Psychiatry and Behavioral Sciences Faculty Publications

Individuals with Autism Spectrum Disorder (ASD) appear to show a general face discrimination deficit across a range of tasks including social–emotional judgments as well as identification and discrimination. However, functional magnetic resonance imaging (fMRI) studies probing the neural bases of these behavioral differences have produced conflicting results: while some studies have reported reduced or no activity to faces in ASD in the Fusiform Face Area (FFA), a key region in human face processing, others have suggested more typical activation levels, possibly reflecting limitations of conventional fMRI techniques to characterize neuron-level processing. Here, we test the hypotheses that face discrimination abilities …

Reinforcing, Subjective, And Cognitive Effects Of Methamphetamine During D-Amphetamine Maintenance, Erika Pike

Theses and Dissertations--Psychology

Translational research suggests that agonist replacement may be a viable treatment approach for managing methamphetamine dependence. This study sought to determine the effects of d-amphetamine maintenance on methamphetamine self-administration in stimulant using participants. A cognitive battery was used to determine the performance effects of methamphetamine alone and during d-amphetamine maintenance. During each maintenance condition, participants first sampled a dose of intranasal methamphetamine then had the opportunity to respond on a progressive ratio task to earn portions of the sampled dose. Subject-rated drug-effect and physiological measures were completed prior to and after sampling methamphetamine. Methamphetamine was self-administered as function …

Venlafaxine-Induced Orthostatic Hypotension In A Geriatric Patient, Vidyashree Chikkaramanjegowda, Jose De Leon

Psychiatry Faculty Publications

Venlafaxine is not usually associated with risk of orthostatic hypotension. A 65-year-old US Caucasian female taking 225 mg/day of venlafaxine extended-release developed symptomatic orthostatic hypotension. The systolic and diastolic blood pressure dropped by 25 and 18 mm Hg, respectively, from supine position to standing position within 3 minutes. The patient was otherwise healthy and the orthostatic hypotension resolved with venlafaxine discontinuation. This was a probable venlafaxine adverse drug reaction according to the Naranjo scale. This case contributes to the scarce literature that indicates that clinicians need to be aware that occasionally venlafaxine can induce clinically significant orthostatic hypotension, particularly in …

Hunger And Reduced Self-Control In The Laboratory And Across The World: Reducing Hunger As A Self-Control Panacea, Matthew T. Gailliot

Faculty Publications

Ten studies link hunger to reduced self-control. Higher levels of hunger-as assessed by self-report, time since last eating, or physiology-predicted reduced self-control, as indicated by increased racial prejudice, (hypothetical) sexual infidelity, passivity, accessibility of death thoughts and perceptions of task difficulty, as well as impaired Stroop performance and decreased self-monitoring. Increased rates of hunger across 200 countries predicted increased war killings, suggestive of reduced aggressive restraint. In a final experiment, self-reported hunger mediated the effect of hungry (v fed) participants performing worse on the Stroop task, suggesting a causal relationship of hunger reducing self-control.

Vascular Depression: An Early Warning Sign Of Frailty, Daniel Paulson, Peter A. Lichtenberg

Psychology Faculty Research Publications

Objectives: Frailty is a common geriatric disorder associated with ADL impairment, hospitalization, and death. Phenomenological evidence suggests that late-life depression (Katz, 2004), particularly vascular depression, may be a risk factor for frailty. This study tests that hypothesis.

Methods: We identified a sample of stroke-free women over the age of 80 from the Health and Retirement Survey. The sample included 984 respondents in 2000 (incidence sample). Of these, 459 were non-frail at baseline and still alive in 2004 (prevalence sample). Frail respondents experienced at least three of the following: wasting, exhaustion, weakness, slowness, and falls. Vascular depression was represented using two …

Subordinate-Supervisor Demographic And Perceived Value Similarity: Relationships To Subordinate Perceptions Of Organizational Justice, Charles Levi Wells, Iv

Wayne State University Dissertations

The purpose of this study was to examine the empirical relationship between subordinate-supervisor demographic and value similarity with subordinate perceptions of organizational justice using three structural equation models. The first model indicated that subordinate-supervisor demographic and value similarity were directly related to subordinate perceptions of organizational justice (Direct Model). The second model indicated that subordinate perceived value similarity with their supervisor mediated the relationship between the subordinate-supervisor demographic similarity and subordinate perceptions of organizational justice (Mediated Model). The last model indicated subordinate perceived value similarity with their supervisor moderated the relationship between subordinate-supervisor demographic similarity and subordinate perceptions of organizational …

Dispositional Mediators Of Burnout Syndrome In A Sample Of Direct Care Staff Employed At Group Homes In A Midwestern State, Cristovao Bartolo Carreira

Wayne State University Dissertations

The current research examined the dispositional characteristics that mediated burnout syndrome in a sample of direct care workers who were employed in group homes for the mentally ill in a Midwestern state. Specifically, the indirect effects that the direct care staff's attachment systems and problem solving ability were examined as they applied to their potential burnout status. Attachment theory, a contemporary psychodynamic theory of personality, was used to provide a context for the study. The researcher studied the interactions between construct subcomponents to address a criticism in the literature stating that only total scores were used to study burnout and …

The Impact Of Exercise On Suicide Risk: Examining Pathways Through Depression, Ptsd, And Sleep In An Inpatient Sample Of Veterans, Collin L. Davidson, Kimberly A. Babson, Marcel O. Bonn-Miller, Tasha Souter, Steven D. Vannoy

Steven D Vannoy

Suicide has a large public health impact. Although effective interventions exist, the many people at risk for suicide cannot access these interventions. Exercise interventions hold promise in terms of reducing suicide because of their ease of implementation. While exercise reduces depression, and reductions in depressive symptoms are linked to reduced suicidal ideation, no studies have directly linked exercise and suicide risk. The current study examined this associ- ation, including potential mediators (i.e., sleep disturbance, posttraumatic stress symptoms, and depression), in a sample of Veterans. SEM analyses revealed that exercise was directly and indirectly associated with suicide risk. Additionally, exercise was …
