Flight Deck Display Technologies For 4dt And Surface Equivalent Visual Operations, Lawrence (Lance) J. Prinzel Iii, Denise R. Jones, Kevin J. Shelton, Jarvis (Trey) J. Arthur, Randall E. Bailey, Angela S. Allamandola, David C. Foyle, Becky L. Hooey

International Symposium on Aviation Psychology - 2009

NASA research is focused on flight deck display technologies that may significantly enhance situation awareness, enable new operating concepts, and reduce the potential for incidents/accidents for terminal area and surface operations. The display technologies include surface map, head-up, and head-worn displays; 4DT guidance algorithms; synthetic and enhanced vision technologies; and terminal maneuvering area traffic conflict detection and alerting systems. This work is critical to ensure that the flight deck interface technologies and the role of the human participants can support the full realization of the Next Generation Air Transportation System (NextGen) and its novel operating concepts.

Risk Assessment In Aviation, Robert Mauro, Immanuel Barshi

International Symposium on Aviation Psychology - 2009

In aviation, many actions are taken to reduce risk. However, not all risks can be avoided. To effectively manage risk, managers and regulators must evaluate and compare risks associated with different threats. Yet, it is frequently difficult to obtain reasonable assessments of these risks. Traditional approaches often produce unsatisfactory results when the probability of failure is low but the costs of failure are high -- as is often the case in modern civil aviation. Attempts to use a single dimension to evaluate threats often lead to unreliable and contentious assessments. Many risk assessment heuristics and displays can yield misleading and …

Predicting The Unpredictable: Estimating Human Performance Parameters For Off-Nominal Events, Becky L. Hooey, Christopher D. Wickens, Ellen Salud, Angelia Sebok, Shaun Hutchins, Brian F. Gore

International Symposium on Aviation Psychology - 2009

A parameter meta-analysis was conducted to characterize human responses to off-nominal events. The probability of detecting an off-nominal event was influenced by characteristics of the offnominal event scenario (phase of flight, expectancy, and event location) and the presence of advanced cockpit technologies (head-up displays, highway-in-the-sky displays, datalink, and graphical route displays). The results revealed that the presence of these advanced technologies hindered event detection reflecting cognitive tunneling and pilot complacency effects.

Conflict Alerts And False Alerts In En-Route Air Traffic Control: An Empirical Study Of Causes And Consequences, Christopher D. Wickens, Stephen Rice, David Keller, Jamie Hughes, Shaun Hutchins

International Symposium on Aviation Psychology - 2009

We analyzed the extent to which a high false alert rate of the conflict alerting (CA) system in five ATC facilities was the cause of a “cry-wolf” effect, whereby true alerts of a pending loss of separation were associated with either controller failure to respond or a delayed response. Radar track data surrounding 497 CA’s were examined and from these we extracted information as to whether the alert was true or false, whether a trajectory change was (response) or was not (non-response) evident, whether a loss of separation occurred, and the controller response time to the CA. Results revealed an …

Professionalism In Airline Operations?...And Accident Investigation?, Captain Kevin M. Smith, Ronald John Lofaro Phd

International Symposium on Aviation Psychology - 2009

When we read the findings of NTSB report AAR-07/06, Southwest Airlines flight #1248, we felt transported to a parallel universe whose occupants seem to be lacking any ability to reason analytically. These “findings’ seemed to turn logic on its head, were insufficient in scope and incorrect as to causation. This paper will analyze the SW accident using the ODM model; will show the deficiencies in the NTSB report and finally, a. Indicate how to design line oriented flight training (LOFT) scenarios that reflect actual operating conditions and are aircraft type-specific. b. Show where/how a separate DM crew training module should …

The Effect Of Video Weather Training Products On General Aviation Pilots’ Flight Behavior, William Knecht, Jerry Ball

International Symposium on Aviation Psychology - 2009

This study examined the effect of video weather training products on general aviation (GA) pilot flight behavior. Fifty pilots participated. Training products were two popular GA weather training videos, plus a non-weather video as control. Pilots watched one video. Then, in the CAMI flight simulator, they flew a challenging 1.5-h visual flight rules (VFR) mission. Along the route, terrain rose slowly, with cloud bases squeezing pilots between ground and clouds. The control group penetrated significantly farther into the deteriorating weather. Otherwise, no significant safety differences were observed for time spent in instrument meteorological conditions (IMC), time scud running, or time …

International Symposium on Aviation Psychology - 2009

The objective of this research was to develop a model of pilot cognitive behavior to predict performance and workload while using varying degrees of cockpit automation to serve as a basis for future systems design. A cognitive task analysis (CTA) was conducted on expert pilot performance a flight control panel (FCP), control-display unit (CDU) and flight management system, and an enhanced CDU (CDU+) providing pre-programmed arrivals from air traffic control in a simulated landing and approach task. Cognitive models were developed from the CTA using an enhanced form of the GOMS language, including a set of additional task operators, to …

Aviator 2030 - Ability Requirements In Future Atm Systems, Hinnerk Eißfeldt

International Symposium on Aviation Psychology - 2009

‘Aviator 2030’ is a project at DLR on ability requirements for operators in future ATM systems. Several workshops have been conducted with pilots and air traffic controllers to learn how today’s aviation professionals see their jobs develop in future. Using separated workshops first, pilots and air traffic controllers were introduced to current developments within the context of Single European Sky SES, a large-scale program comparable to NextGen in the United States. Following the ‘future-workshop’ concept participants developed scenarios of future ATM from their professional background and experience. In a third workshop pilots and controllers met to exchange and discuss their …

A Methodology And Tools For The Prospective Identification Of Nextgen Human Factors Issues, Ken Funk

International Symposium on Aviation Psychology - 2009

The Human-Machine Systems Engineering Methodology (HMSEM) is a systematic method to prospectively identify relevant human fallibilities, potential errors, and general human factors issues in a complex, high-risk system, then develop design recommendations for remediations to counteract the fallibilities, avoid or mitigate the errors, and resolve the issues. HMSEM uses IDEF0 functional modeling, task analysis, human fallibilities analysis, and Failure Modes and Effects Analysis, organizing the information for and from the analyses in a workbook. The results of its application to several tasks on the NextGen flight deck suggest that it can be a valuable complement to other means to anticipate …

Near-Term Nextgen And Class 2 Efbs, Thomas L. Seamster Ph.D., Barbara G. Kanki Ph.D.

This study is based on data collected at the Electronic Flight Bag (EFB) Advanced Software and Authorization Workshop for US operators currently involved in EFB software evaluation or implementation for their own fleets. With most US operators not taking delivery of new, larger aircraft in the next few years, they are considering ways of displaying near-term NextGen data on board existing aircraft through systems such as the EFB. The workshop collected operator near-term needs in the areas of EFB user interface and standardization and EFB advanced software applications. The analysis of the data collected during the workshop provided a prioritized …

Vigilant Warrior™: A Selection Tool For Vigilance Performance, David E. Weldon Ph.D., Clark Shingledecker Ph.D.

International Symposium on Aviation Psychology - 2009

In this paper, we describe an individual differences model of vigilance performance—the ability to maintain one’s focus of attention and remain alert for prolonged periods of time—and summarize our model evaluation research. Our goal was an automated test battery (Vigilant Warrior™) that could be employed to select personnel with superior abilities for assignment to critical vigilance duties. Thus, we conducted extensive laboratory research to identify an optimal set of vigilance predictors and validate them against a simulated, real-world, electronic-display, battlefieldmonitoring task with high vigilance requirements. The results confirmed that an objective, Short Vigilance Task (SVT), coupled with analytic skill and …

The Technological, Financial, And Social Realities That Are Defining The Aircraft Mechanic Of Tomorrow, Glen R. Gallway

International Symposium on Aviation Psychology - 2009

Today it is becoming increasingly difficult to describe maintenance roles because an enormous number of once stable factors affecting the maintenance person and process are changing. Technology changes like software based aircraft, air/ground/satellite/airport system integration, highly complexity systems, and other technology issues are not currently part of a maintenance person’s normal skill set but are already part of aircraft maintenance needs. Many of the change issues that are considered to be “TECHNOLOGY” initiated but usually are caused by changing financial and/or social requirements that has occurred. This is a circular result in that when technology changes occur it further drives …

Simulator Motion…It Rocks! (Or Maybe Not), Bob Jacobs

International Symposium on Aviation Psychology - 2009

I want to briefly share some of our early work at the University of Illinois Aviation Research Laboratory relating to the nature and role of motion cueing and its relationship to pilot performance in flight training, skill evaluation, and flight instrument utilization. First, though, I’d like to offer some personal testimony about Stan Roscoe, the director of the Lab, so that you can appreciate the extraordinary environment we were provided in which to pursue our research and to learn.

Aspergers Syndrome has recently become a "popular" topic in the mental health fields. More and more school aged children are being formally diagnosed with the disorder. Yet, many professionals do not truly understand the nature of Aspergers syndrome beyond being a form of autism. In this paper Aspergers Syndrome is defined and compared with Autism and the causes and possible treatments are discussed, particularly from biological and sociocultural points of view.

Alterations In Default Network Connectivity In Posttraumatic Stress Disorder Related To Early Life Trauma, Robyn L. Bluhm, Peter C. Williamson, Elizabeth A. Osuch, Paul A. Frewen, Todd K. Stevens, Kristine Boksman, Richard W.J. Neufeld, Jean Théberge, Ruth A. Lanius

Philosophy Faculty Publications

Background: The "default network" consists of a number of brain regions that exhibit correlated low-frequency activity at rest and that have been suggested to be involved in the processing of self-relevant stimuli. Activity in many of these areas has also been shown to be altered in individuals with posttraumatic stress disorder (PTSD). We hypothesized that the posterior cingulate cortex (PCC)/precuneus, part of the default network, would exhibit altered connectivity at rest with other areas of the default network and regions associated with PTSD.

Methods: Seventeen medicated and unmedicated female patients with chronic posttraumatic stress disorder (PTSD) related to early-life trauma …

Resting State Default-Mode Network Connectivity In Early Depression Using A Seed Region-Of-Interest Analysis: Decreased Connectivity With Caudate Nucleus, Robyn Bluhm, Peter Williamson, Ruth Lanius, Jean Théberge, Maria Densmore, Robert Bartha, Richard Neufeld, Elizabeth Osuch

Philosophy Faculty Publications

Aim: Reports on resting brain activity in healthy controls have described a default-mode network (DMN) and important differences in DMN connectivity have emerged for several psychiatric conditions. No study to date, however, has investigated resting-state DMN in relatively early depression before years of medication treatment. The objective of the present study was, therefore, to investigate the DMN in patients seeking help from specialized mental health services for the first time for symptoms of depression.

Methods: Fourteen depressed subjects and 15 matched controls were scanned using 4-T functional magnetic resonance imaging while resting with eyes closed. All but one subject was …

Nonlinear Dynamics Of Infant Sitting Postural Control, Joan E. Deffeyes

Department of Psychology: Dissertations, Theses, and Student Research

Sitting is one of the first developmental milestones that an infant achieves. Thus measurements of sitting posture present an opportunity to assess sensorimotor development at a young age, in order to identify infants who might benefit from therapeutic intervention, and to monitor the efficacy of the intervention. Sitting postural sway data was collected using a force plate from infants with typical development, and from infants with delayed development, where the delay in development was due to cerebral palsy in most of the infants in the study. The center of pressure time series from the infant sitting was subjected to a …

Self-Mutilation : A Growing Concern, Sarah M. Meiners

Graduate Research Papers

According to an article by Nock and Prinstein, "Self-mutilation behavior is a pervasive public health problem occurring at a rate of 40% in the general adult population and 21 % in adult clinical populations. Adolescence is a period of significantly increased risk for self-mutilation behavior, as evidenced by rates of 14%-39% in adolescent community samples" (Nock & Prinstein, 2005, p.140). Raising awareness about the behaviors and emotions involved with individuals who self-mutilate may help counselors and school administrators understand better methods of treatment for adolescents. The following is a review of current research and literature regarding the nature of adolescents …

Impairments In Attention In Occasionally Snoring Children: An Event-Related Potential Study, Maria E. Barnes, Elizabeth A. Huss, Krista N. Garrod, Eric Van Raay, Ehab Dayyat, Dennis L. Molfese

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Objective—To determine whether minimal snoring is benign in children.

Procedure—22 rarely snoring children (mean age=6.9 years, 11 females) and age- and sexmatched controls participated in an auditory oddball task wearing 128-electrode nets. Parents completed Conner’s Parent Rating Scales-Revised Long (CPRS-R:L).

Results—Snorers scored significantly higher on 4 CPRS-R:L subscales. Stepwise regression indicated that two ERP variables from a region of the ERP that peaked at 844 ms post-stimulus onset predicted CPRS-R:L ADHD Index scores.

Conclusions—Occasional snorers according to parental report do exhibit ADHD-like behaviors. Basic sensory processing is longer than in controls, suggesting that delayed frontal activation requires more effort in …

Persons As Contexts: Evaluating Between-Person And Within-Person Effects In Longitudinal Analysis, Lesa Hoffman, Robert S. Stawski

Department of Psychology: Faculty Publications

Relationships among multiple variables over time are of interest in many developmental areas and are frequently examined using time-varying predictors in multilevel models. Yet an incomplete specification of time-varying predictors will usually result in biased model effects. Specifically, the impact of constant, between-person sources of variation must be differentiated from the impact of time-specific, within-person sources of variation -that is, persons should be modeled as contexts. The current didactic article expands upon previous work to address why and how to model persons as contexts in longitudinal analysis. An electronic appendix of syntax for estimating these models is also provided.

Educating Clinical Pastoral Education Supervisors: A Grounded Theory Study Of Supervisory Wisdom, Judith R. Ragsdale

Antioch University Dissertations & Theses

Clinical Pastoral Education (CPE) is an 80 year old education modality that provides professional education for students of pastoral care. Supervision is central to the CPE process. Pastoral supervisors in the Association for Clinical Pastoral Education (ACPE) have done little writing about their work educating Students in Supervisory Education (SSEs). The purpose of this dissertation is to identify and interview those practitioners in ACPE who have been identified by their peers as excellent in practice, and to cull their wisdom by listening to and categorizing their experience of supervising SSEs. The research question to the supervisors was: What is your …
