A Study Of Accidents And Incidents Of Landing On Wrong Runways And Wrong Airports, Linfeng Jin, Edmund Lo
A Study Of Accidents And Incidents Of Landing On Wrong Runways And Wrong Airports, Linfeng Jin, Edmund Lo
International Symposium on Aviation Psychology - 2017
This paper addresses the landings on wrong runways/ at wrong airports happened between 03/26/1992 and 05/08/2012. The visibility, intended landing runway heading, accident landing runway heading, pilots’ flight hours, and the ages of those pilots are studied to test whether they have correlationswith the number of personnel injury, the number of personneldeath, and the degrees of aircraft damage. Some significantfindings are: the most likely angular difference between the supposed landing runwayheadings and wrong runway headings among wrong runway/airport landingsis 180 degrees,and there is a weaknegative correlation between aircraft damage and pilot flight hours. All the data used in the paper …
Is Rho The Key To Hazardous Weather Avoidance?, William R. Knecht
Is Rho The Key To Hazardous Weather Avoidance?, William R. Knecht
International Symposium on Aviation Psychology - 2017
Current in-cockpit looping Next-Generation Radar (NEXRAD) is inadequate to maintain safe (20 nm) aircraft separation from heavy weather (> 40 dBZ reflectivity). This assertion issupported by mathematical information analysis and an empirical study (Knecht, 2016), as well as numerous previous empirical studies. The current work revisitsthe ecological analysis by examining the putative affordance (rho) specifying when weather-avoidance maneuver should begin, as suggested by General Tau Theory (Lee, 2009).With“gapdefined as the distance between the on-screen aircraft icon and the weather hazard, is specified by the ratio ((dg/dt)/g)(t), the instantaneous gap contraction rate divided by the instantaneous gap size. In current …

A Case Study Using The Human Factors Analysis And Classification System Framework, Flavio A.C. Mendonca Ph.D., Chenyu Huang Ph.D., Julius Keller Ph.D.
International Symposium on Aviation Psychology - 2017
Aircraft accidents are generally the end result of a number of latent conditions arising in the organizational and managerial sectors. These conditions frequently permit or even motivatethe unsafe acts by the flight crew. The Human Factors Analysis and ClassificationSystem (HFACS) is a system safety tool for the investigation and analysis of underlying human causal factors in aircraft accidents. Using the HFACS framework, four researchers classified the human factors identified by the Brazilian Aeronautical AccidentsInvestigation and Prevention Center (CENIPA) during the investigation of a mishap(PR-AFA) that happened in Brazil in 2014. CENIPA argued that errors and violations by both pilots contributed …

Usaf Spatial Disorientation Prevention: A Meta-Analytical Human Systems Integration Perspective, Patrick O'Neil, Booz Allen Hamilton, Michael Miller
International Symposium on Aviation Psychology - 2017
Human Systems Integration involvesthe systematic consideration of tradeoffs in system structure or behavior, which affect sevenhuman-centered domains to optimize total system performance and life cycle cost.All too often, HSI is overlooked or poorly practiced, despite the specific directive within DoDI 5000.02 for program managers to plan for and conduct HSI. In the worst of cases, poor consideration of human capabilitiesandlimitations leads to errors, mishaps, and death or serious injury. One such human limitation in aviation is the inability of the pilot to maintain proper spatial orientationduring flight,asmismatches between the stimuli present during flight create an erroneous perception of aircraft attitude …
Understanding Pilots’ Explanations Of Automation Surprises, Robert Mauro, Loukia Loukopoulou, Julia Trippe
Understanding Pilots’ Explanations Of Automation Surprises, Robert Mauro, Loukia Loukopoulou, Julia Trippe
International Symposium on Aviation Psychology - 2017
Automation surprise may result from inadequate or mistaken “mental models” of the automation (Sarter and Woods, 1995). To study pilots’ mental models of their automation, 202 airline pilots were asked to explain five different events involving unexpected behaviors of aircraft automation. Pilots’ abilities to correctly explain the behavior of the automation differed systematically across the scenarios. The number of complete and correct responses varied from 19% to 86%, depending on the scenario. As the complexity of the automation increased, understanding decreased. Performance on the scenarios was not related to flight experience, automation experience, or source of automation training. But pilots’ …
Operationalizing The Definition Of Risk As Variability, Julia Pounds, Paul Krois, Barry C. Davis, Melissa Wishy
Operationalizing The Definition Of Risk As Variability, Julia Pounds, Paul Krois, Barry C. Davis, Melissa Wishy
International Symposium on Aviation Psychology - 2017
Maintaining safety requires acknowledgingrisk. However, one’s definition of risk can depend on whether the word is being used in everyday conversation or by safety practitioners or by domain experts. Not having a commonly agreed-upon definition poses problems for those charged with identifying, reducing, and communicating about risk. In an effort to standardize the definition, the International Organization for Standardization defined risk simply as the effect of uncertainty on objectives. Still, this general definition lacks enough specificity to describe uncertainty’s positive or negative effects. Relevant information can reduce uncertainty’s potential effects if it’s not ambiguous, unreliable, incomplete, or unavailable.

Investigating Pilot’S Decision Making When Facing An Unstabilized Approach: An Eye-Tracking Study, Maxime Reynal, Frank Rister, Sebastien Scannella, Christopher Wickens, Frederic Hehais
International Symposium on Aviation Psychology - 2017
Unstabilized approach has been identified to be a major causal factor of approach-and-landing accidents (e.g. off-runway touchdowns, hard landing, tail-strikes, etc).We conducted an experimentin order to analyze pilots’ performance during such approaches. Ten type-rated, commercial pilots flew each in a B737 full-flight simulator during anunstabilizedapproach at Hamburg airport. The Pilot Flyings’ (PF) eye gazes were collected. The results revealed that half of the pilots persisted in an erroneous landing decision. These latter pilots had higher dwell time on the attitude indicator/flight director whereas the group of pilots who perfomed the go-around exhibited more fixations on the navigation display prior to …
A Trend Analysis Of Human Factors Issues In Uk Military Aviation, Sarah Weedon, Victoria Cutler, Saskia Revell
A Trend Analysis Of Human Factors Issues In Uk Military Aviation, Sarah Weedon, Victoria Cutler, Saskia Revell
International Symposium on Aviation Psychology - 2017
Human factors issues in UK military aviation are identified and mitigated through a combination of proactive support and reactive investigations, both of which employ qualitativedata collection and analysis methods. Each piece of work to identify human factors issues is performed on a standalone basis, but a regular review is undertaken to identify common trends. In the most recent review of trends, thematic analysis was used within the framework of the Accident Route Matrix to determine the most prevalent and qualitatively important human factors issues. The thematic analysis identified a wide range of human factors issues, including resource availability, training, documentation, …

Alerts On The Nextgen Flight Deck, Angelia Sebok, Christopher D. Wickens, Brett Walters, Karl Fennell
International Symposium on Aviation Psychology - 2017
The future generation of cockpit may substantially change the nature of displays, automation, and their implications for alerting systems. Flight deck automation and information systems imposed by NextGen will create system states that may need to be alerted. New concepts of providing continuous flight information can benefit pilot awareness. Ecological interface displayskeep the operator aware of the system status and constraints, informing the pilot of emerging concerns before an alert is triggered. Continuous auditory and tactile displays support pilot awareness without requiring focused operatorattention. Both approaches improve awareness of system state, but suffer poor operator acceptance. Automation can support pilots …

Effects Of Simulator Training For Unmanned Aerial Systems In Undergraduate Education, William Weldon, Dr. Brian Kozak
International Symposium on Aviation Psychology - 2017
Unmanned aerial systems (UAS) are being added to the national airspace (NAS) in very large numbers. Many universities have seen this demand for UAS operators and begun to create programs in order to train undergraduate students in their use. The UAS industry currently lacks adequatetraining requirements for beginning operators. This fact makes university training important, because universities are oneof the few places that offer structured training. While the UAS industry in the US is in its infancy it is possible to draw parallelismsthe training history of manned flight in order to avoid pitfalls and offer training in the most efficient …

Fatiguing The Force: Using Operational Data To Improve The United States Air Force’S Mission Effectiveness Model, Kelly M. Amaddio, Jennifer P. Howland
International Symposium on Aviation Psychology - 2017
Air mobility pilots routinely fly multiple missions spanning several time zones, thereby disrupting their circadian rhythm. As a result, they consistently operate at a sub-optimal performance level. After several fatigue-related accidents, the Air Mobility Command (AMC) Safety Office incorporated the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE) model into its Aviation Operational Risk Management (AvORM) program to inform aircrew members of their fatigue levels during critical phases of flight. Further analysis indicated that aircrew members experience higher fatigue levels than predicted, which directly reduces flight safety. This study seeks to improve the underlying assumptions within the sleep model to more …

International Symposium on Aviation Psychology - 2017
The current study evaluatedthe utility of electroencephalography (EEG) cognitive state to track workload and engagement changes in air traffic control students of differing experience during a Terminal Radar Approach Control (TRACON) scenario. EEG recordings were collected from 47 air traffic control students (27 with high and 20 with low experience) during a five phase TRACON scenario. The scenario fluctuated in the number of aircraft released per phase and the presence or absence of uncontrolled departures/arrivals. EEG workload probabilities werehigher during the phase with uncontrolled departures/arrivals and maximum number of aircraft compared to phases with no uncontrolled arrivals/departures and fewer aircraft. …

An Eeg Data Investigation Using Only Artifacts, Chelsey Credlebaugh, Paul Middendorf, Matt Middendorf, Scott Galster
International Symposium on Aviation Psychology - 2017
For decades, it has been reportedthat theelectroencephalogram (EEG) isa positive indicator of mental workload. However, EEG signals are easily affected by artifacts.Anartifact mediation approach, called artifact separation, was developed to enable the consumer of the EEG data to decide how to handle artifacts. The current investigation uses onlydata contaminated by artifacts and discards the artifact free data.This was doneto solve a problem associated with data collection.Specifically, in an experiment, EEGelectrodeleadsforT3 and Fzwere swapped where they were connected to the signal acquisition hardware. To facilitate analysis of the data, it was essential to determine whenthe swap occurred. This was accomplished using …
Cognitive Constraints For Automation On Flight Testing, Diogo Silva Castilho
Cognitive Constraints For Automation On Flight Testing, Diogo Silva Castilho
International Symposium on Aviation Psychology - 2017
The first flight of a new aircraft is still a dangerous event. Despite all simulations and software predictions, test pilots face many unknowns when a prototype leaves the ground for the first time. The cultural celebration of first flights masks the concerns of many stakeholders about the technical challenges of the new equipment. The pilot extensively prepares to react properly to unexpected situations and often bring a new story to tell, but in a time whenremotely piloted and autonomous aircraft fly every day, the question about how to use their technologies to save a test pilot life arises. This study …
The Neuropsychology Of Sport And Performance, Arthur C. Maerlender
The Neuropsychology Of Sport And Performance, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty Publications
Neuropsychological theory has been a mainstay for understanding pathology within the brain-behavior context. However, our theories for predicting superior behavior are not as well developed. Sport neuropsychology was developed on the presumption that athletes represent a population in a relatively well-controlled environment for studying brain pathology due to injury. This study of pathology within a high-performance environment has been responsible for identifying the effects of mild traumatic brain injury (mTBI) on individual functioning. Far less attention has been paid to the other end of the performance continuum, and yet, viable brain-behavior hypotheses should hold true across the spectrum of function …

Validity And Reliability Of Baseline Testing In A Standardized Environment, Kathryn L. Higgins, Todd Caze, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty Publications
Objective — The Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to determine cognitive recovery from concussion based on comparing post-injury scores to baseline scores. This model is based on the premise that ImPACT baseline test scores are a valid and reliable measure of optimal cognitive function at baseline. Growing evidence suggests that this premise may not be accurate and a large contributor to invalid and unreliable baseline test scores may be the protocol and environment in which baseline tests are administered. This study examined the effects of a standardized environment and administration …

Objective: Hundreds of scientific publications are produced annually that involve the measurement of cortisol in saliva. Intra- and inter-laboratory variation in salivary cortisol results has the potential to contribute to crossstudy inconsistencies in findings, and the perception that salivary cortisol results are unreliable. This study rigorously estimates sources of measurement variability in the assay of salivary cortisol within and between established international academic-based laboratories that specialize in saliva analyses. One hundred young adults (Mean age: 23.10 years; 62 females) donated 2 mL of whole saliva by passive drool. Each sample was split into multiple- 100 μL aliquots and …

Center for Brain, Biology, and Behavior: Faculty Publications
School-based concussion management programs cover thousands of young athletes, yet there is little in the way of research to assess program processes or outcomes. This study examined the referral patterns of consultants working with ten high school concussion management programs. In addition to the number of referrals made to specialists, other potential outcome variables were explored. The sample included over 5,000 athlete-seasons and 298 concussions managed directly by certified athletic trainers. All programs used computerized neuropsychological testing (both baseline and post injury). Two groups were compared: five programs used a clinical neuropsychologist (NP) as the testing consultant and five used …

Center for Brain, Biology, and Behavior: Faculty Publications
Chronic ankle instability (CAI) is often debilitating and may be affected by a number of intrinsic and environmental factors. Alterations in neurocognitive function and attention may contribute to repetitive injury in those with CAI and influence postural control strategies. Thus, the purpose of this study was to determine if there was a difference in attentional functioning and static postural control among groups of Comparison, Coper and CAI participants and assess the relationship between them within each of the groups. Recruited participants performed single-limb balance trials and completed the CNS Vital Signs (CNSVS) computer-based assessment to assess their attentional function. Center …

Sandbagging On The Immediate Post-Concussion Assessment And Cognitive Testing (Impact) In A High School Athlete Population, Kathryn L. Higgins, Robert L. Denny, Arthur C. Maerlender
Center for Brain, Biology, and Behavior: Faculty Publications
The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called “sandbagging,” in order to return to their baseline cognitive scores, and thus to play, more quickly. This research examines ImPACT baseline scores when high school athletes were asked to attempt to “sandbag,” and compares those scores with scores …

Center for Brain, Biology, and Behavior: Faculty Publications
High levels of endurance training have been associated with potentially negative health outcomes and addictive-like symptoms such as exercise in the presence of injury and higher levels of impulsivity. This pilot study examined the relationships among self-report measures of addictive symptoms related to exercise and behavioral and neural measures of impulsivity in endurance runners. We hypothesized endurance runners would have increased preference for immediate rewards and greater activation of cognitive control regions when making decisions involving delayed rewards. Twenty endurance runners (at least 20 miles/week) were recruited to undergo measures of self-report exercise addiction symptoms, impulsive decision-making (delay discounting) and …

Center for Brain, Biology, and Behavior: Faculty Publications
Lateral hypothalamic area (LHA) local field potentials (LFPs) were recorded in a Prader–Willi patient undergoing deep brain stimulation (DBS) for obesity. During hunger, exposure to food-related cues induced an increase in beta/ low-gamma activity. In contrast, recordings during satiety were marked by prominent alpha rhythms. Based on these findings, we have delivered alphafrequency DBS prior to and during food intake. Despite reporting an early sensation of fullness, the patient continued to crave food. This suggests that the pattern of activity in LHA may indicate hunger/satiety states in humans but attest to the complexity of conducting neuromodulation studies in obesity.

Developmental Disabilities And Family Dynamics, Meghan Murray
Developmental Disabilities And Family Dynamics, Meghan Murray
ETD Archive
Typically developing (TD) siblings of children with an Intellectual or Developmental Disability (IDD) are among those most influenced by their sibling’s diagnosis. Factors such as increased family stress, lack of family communication, and negative sibling perception can play a role in leading to internalizing and externalizing problems from the TD child. A limit to the existing sibling relationship literature is that the relationships in families with a child with IDD have only been collected via self-report measures through which respondents have been found to fake their responses to avoid being perceived in certain ways. Conversely, implicit measures, such as the …
