Adversity, particularly in early life, can cause illness. Clues to the responsible mechanisms may lie with the discovery of molecular signatures of stress, some of which include alterations to an individual’s somatic genome. Here, using genome sequences from 11,670 women, we observed a highly significant association between a stress-related disease, major depression, and the amount of mtDNA (p = 9.00 × 10−42, odds ratio 1.33 [95% confidence interval [CI] = 1.29–1.37]) and telomere length (p = 2.84 × 10−14, odds ratio 0.85 [95% CI = 0.81–0.89]). While both telomere length and mtDNA amount were associated with adverse life events, conditional …

Psychiatry Publications

Generalised Anxiety Disorder (GAD) is a common anxiety-related diagnosis, affecting approximately 5% of the adult population. One characteristic of GAD is a high degree of anxiety sensitivity (AS), a personality trait which describes the fear of arousal-related sensations. Here we present a genome-wide association study of AS using a cohort of 730 MZ and DZ female twins. The GWAS showed a significant association for a variant within the RBFOX1 gene. A heritability analysis of the same cohort also confirmed a significant genetic component with h2 of 0.42. Additionally, a subset of the cohort (25 MZ twins discordant for AS) was …

Integrating Basic Research With Prevention/Intervention To Reduce Risky Substance Use Among College Students, Danielle Dick, Linda C. Hancock Jan 2015

Integrating Basic Research With Prevention/Intervention To Reduce Risky Substance Use Among College Students, Danielle Dick, Linda C. Hancock

Psychiatry Publications

Too often basic research on etiological processes that contribute to substance use outcomes is disconnected from efforts to develop prevention and intervention programming. Substance use on college campuses is an area of concern where translational efforts that bring together basic scientists and prevention/intervention practitioners have potential for high impact. We describe an effort at a large, public, urban university in the United States to bring together researchers across the campus with expertise in college behavioral health with university administration and health/wellness practitioners to address college student substance use and mental health. The project “Spit for Science” examines how genetic and …

Psychiatry Publications

Background. The objective is to analyze and compare Virginia suicide data from 2003 to 2012 to US suicide data. Methods. Suicide trends by method, age, gender, and race were obtained from Virginia’s Office of the Chief Medical Examiner’s annual reports. Results. Similar to US suicide rates, suicide rates in Virginia increased between 2003 and 2012 from 10.9/100,000 people to 12.9/100,000 people. The most common methods were firearm, asphyxia, and intentional drug overdose, respectively. The increase in asphyxia (𝑟 = 0.77, 𝑃 ≤ 0.01) and decrease in CO poisoning (𝑟 = −0.89, 𝑃 ≤ 0.01) were significant. Unlike national trends, intentional …

Age And Trust In Flight Attendants: A Comparison Between Two Countries, Rian Mehta, Natasha Rao, Ethan Labonte, Stephen Rice Jan 2015

Age And Trust In Flight Attendants: A Comparison Between Two Countries, Rian Mehta, Natasha Rao, Ethan Labonte, Stephen Rice

International Symposium on Aviation Psychology - 2015

It is important for passengers to trust their flight attendants, especially in case of an emergency. There is ongoing debate in India regarding trust and the lowering of retirement age, which is currently mandatory at 58 years in flight attendants. Some believe this is in order to acquire younger, more attractive flight attendants. The current study asked 384 Indians and Americans to rate their trust in flight attendants based on an emergency situation. Results showed that Indians trusted the younger flight attendants (25 years old) more than their older counterparts (55 years old). These findings have theoretical and practical implications …

Incorporating New Methods Of Classifying Domain Information For Use In Safety Hazard Analysis, Nancy G. Leveson, Daniel R. Montes, Leia A. Stirling Jan 2015

Incorporating New Methods Of Classifying Domain Information For Use In Safety Hazard Analysis, Nancy G. Leveson, Daniel R. Montes, Leia A. Stirling

International Symposium on Aviation Psychology - 2015

The increase of interacting humans and autonomous components in complex systems necessitates rigorous methods to classify domain information pertaining to controllers in the system. Systems-Theoretic Process Analysis (STPA) was developed at MIT as a method for identifying hazardous scenarios from a system design in order to generate functional system requirements to eliminate or control those scenarios. An STPA analysis, while systems-based and including human operators (e.g., pilots and air-traffic controllers) in the scenarios, is currently limited in the types of human contribution to accidents that it can identify (which are primarily related to situation awareness). This paper extends STPA in …

Experimental Evaluation Of Varying Feedback Of A Cognitive Agent System For Uav Mission Management, Elisabeth Denk, Sebastian Clauss, Annike Borchers, Josef Werner, Axel Schulte Jan 2015

Experimental Evaluation Of Varying Feedback Of A Cognitive Agent System For Uav Mission Management, Elisabeth Denk, Sebastian Clauss, Annike Borchers, Josef Werner, Axel Schulte

International Symposium on Aviation Psychology - 2015

In this study we investigate on a cognitive delegation agent for UAV task-based mission management. Particularly, we advocate a specific high-level feedback provided by the agent to the human operator to enhance mission effectiveness. As extension to human supervisory control we suggest to introduce the concept of agent supervisory control where the agent is delegated by high-level operator commands and controls several sub-systems aboard the UAV fulfilling the mission in highly automated fashion. Results of our experimental human-in-the-loop study focusing on the effects of high-level feedback are presented. Therefore, two configurations are compared, one with basic feedback and one with …

Flight Deck Interval Management Avionics: Eye-Tracking Analysis, Kara Latorella, John W. Harden Jan 2015

Flight Deck Interval Management Avionics: Eye-Tracking Analysis, Kara Latorella, John W. Harden

International Symposium on Aviation Psychology - 2015

Interval Management (IM) is one NexGen method for achieving airspace efficiencies. In order to initiate IM procedures, Air Traffic Control provides an IM clearance to the IM aircraft’s pilots that indicates an intended spacing from another aircraft (the target to follow – or TTF) and the point at which this should be achieved. Pilots enter the clearance in the flight deck IM (FIM) system; and once the TTF’s Automatic Dependent Surveillance-Broadcast signal is available, the FIM algorithm generates target speeds to meet that IM goal. This study examined four Avionics Conditions (defined by the instrumentation and location presenting FIM information) …

Multi-Gain Control: Balancing Demands For Speed And Precision, Lucas Lemasters, John Flach Jan 2015

Multi-Gain Control: Balancing Demands For Speed And Precision, Lucas Lemasters, John Flach

International Symposium on Aviation Psychology - 2015

Woodworth's Two-Component model (1899) partitioned speeded limb movements into two distinct phases: (1) a central ballistic open-loop mechanism and (2) a closed-loop feedback component. The present study investigated the implementation of multi-gain control configurations that utilized separate gain values optimized for each movement phase. A target acquisition task using Fitts' Law (1954) was performed within a virtual environment using multiple control devices with three gain settings: (1) mono-gain, (2) dual-gain, and (3) continuous gain. It was found that dual-gain and continuous gain configurations yielded lower movement times and information-processing rates than the mono-gain configurations. The secondary gain values presented in …

Impact Of Weather Information Latency On General Aviation Pilot Situation Awareness, Barrett S. Caldwell, Mary E. Johnson, Geoffrey Whitehurst, Vladimir Rishukin, Nsikak Udo-Imeh, Lucero Duran, Megan M. Nyre, Lauren Sperlak

International Symposium on Aviation Psychology - 2015

A critical element of situation awareness and sensemaking support for humans in complex environments is the ability to access, detect, and integrate environmental elements to recognize and project the state of the world. Some past research has suggested that new weather technology capabilities in general aviation (GA) flight settings could help improve pilot decision making and reduce accidents such as unintentional transitions from visual flight rules (VFR) to marginal VFR or even instrument meteorological conditions (IMC). This paper addresses an ongoing Federal Aviation Administration (FAA) funded research project investigating the effect of transmission delays and update latencies in presentations of …

Integrating Uas Operations In Class C Airspace, Todd R. Truitt, Randy L. Sollenberger Jan 2015

Integrating Uas Operations In Class C Airspace, Todd R. Truitt, Randy L. Sollenberger

International Symposium on Aviation Psychology - 2015

The Federal Aviation Administration (FAA) is investigating Unmanned Aircraft Systems (UAS) operations in the National Airspace System because military, commercial, and civil users want to fly UAS for a broad range of purposes. Our research addresses the potential impact to Air Traffic Control Specialists (ATCS) due to UAS pilots’ inability to comply with FAA regulations and air traffic control clearances and instructions that require direct visual means. UAS pilots cannot maintain visual separation from other aircraft, report aircraft in sight, or conduct visual approaches. The inability of UAS pilots to rely on visual means may affect ATCS workload, performance, and …

Attentional Narrowing: A First Step Towards Controlled Studies Of A Threat To Aviation Safety, Julie Prinet, Nadine Sarter Jan 2015

Attentional Narrowing: A First Step Towards Controlled Studies Of A Threat To Aviation Safety, Julie Prinet, Nadine Sarter

International Symposium on Aviation Psychology - 2015

Attentional narrowing - the involuntary restriction of attention to a small set of data or one task/goal - is a major concern in many complex, high-risk domains. Research into this phenomenon is much needed but hampered by the difficulty of inducing it reliably in a controlled experimental setting. The present study tested the effectiveness of loud noise and high task demand for achieving this goal. Seven participants performed a visual search task in the context of a simplified air traffic control simulation. Performance and eye tracking data were recorded. Eye tracking metrics showed a narrowing of participants’ visual attentional field …

The Cognition Of Multi-Aircraft Control (Mac): Proactive Interference And Working Memory Capacity, Kelly Amaddio, Michael Miller, John Elshaw, Victor Finomore

International Symposium on Aviation Psychology - 2015

As the number of U.S. Air Force missions requiring UAVs has rapidly increased without commensurate increases in manpower, systems which permit a single operator to supervise and control multiple, highly-automated aircraft are being considered. The operator of such a system may be required to monitor and respond to voice communications for multiple UAVs, each of which can have aircraft specific call signs, which may impose excessive requirements on constrained operator attention, working memory, and cognitive processing. The current research investigates the cognitive load (number of aircraft call signs) an individual can handle and explores the effect of proactive interference (PI) …

Statistical Errors In Aviation Psychology: Commonsense Statistics In Aviation Safety Research, Christopher D. Wickens Jan 2015

Statistical Errors In Aviation Psychology: Commonsense Statistics In Aviation Safety Research, Christopher D. Wickens

International Symposium on Aviation Psychology - 2015

I discuss problems with the use of null hypothesis significance testing, as it is particularly applied to safety research such as that in aviation psychology. Such problems are manifest in the inherent bias of traditional statistics to avoid type 1 statistical errors, and hence to discourage findings of safety improving effects as significant, when low powered experimental designs are required by necessary constraints. In contrast, I offer several approaches or remedies. Researchers should think about the decisions made by consumers of their research, based on the costs and values of those decisions; they should form alternative hypotheses, use smart planned …

Requirements For Developing The Model Of Spatial Orientation Into An Applied Cockpit Warning System, Ben D. Lawson, Braden J. Mcgrath, Michael C. Newman, Angus H. Rupert Jan 2015

Requirements For Developing The Model Of Spatial Orientation Into An Applied Cockpit Warning System, Ben D. Lawson, Braden J. Mcgrath, Michael C. Newman, Angus H. Rupert

International Symposium on Aviation Psychology - 2015

Refinements have been made to a model of spatial disorientation (SD) to improve simulation of acceleration stimuli and visual-vestibular interactions. The improved model has been applied to aviation mishaps. The model is considered a technological countermeasure for SD because it is implemented as prototype software to aid the identification of mishap contributors in a way that should benefit didactic training. There is a more direct way this countermeasure can prevent SD, which is by adapting it for use as part of a cockpit warning system. The idea is to expand the model from one which explains mishaps post-hoc into one …

Identifying Representative Symbology For Low Visibility Operations/Surface Movement Guidance And Control System (Lvo/Smgcs) Paper Charts, Andrea L. Sparko, Stephanie G. Chase

International Symposium on Aviation Psychology - 2015

The Volpe Center developed a questionnaire to examine the representativeness of symbol shapes and the usefulness of information depicted on Low Visibility Operations/Surface Movement Guidance and Control System (LVO/SMGCS) paper charts. One-hundred forty-four pilots were shown a series of symbol shapes and responded “Yes” or “No” to whether they considered each symbol shape representative of a given information type. Symbol shapes were presented at increasing levels of context. Pilots then rated the usefulness of information depicted on LVO/SMGCS charts. Pilots identified representative symbol shapes for a geographic position marking, instrument landing system (ILS) hold line, runway guard lights (RGL), stop …

A Valid And Reliable Safety Scale For Passenger’S Perceptions Of Airport Safety, Stephen Rice, Rian Mehta, Scott Winter, Korhan Oyman Jan 2015

A Valid And Reliable Safety Scale For Passenger’S Perceptions Of Airport Safety, Stephen Rice, Rian Mehta, Scott Winter, Korhan Oyman

International Symposium on Aviation Psychology - 2015

Previous research has developed various customer satisfaction scales in many applied areas; however, to our knowledge, there is not a validated scale for measuring commercial airline passengers’ ratings of personal safety based on airport security. The current study seeks to address this missing gap by developing a valid and reliable safety scale for commercial airline passengers (SS-CAP). We first solicited words and phrases that are related to a passenger’s feeling of safety from potential consumers and experts in the field. We then narrowed down the list to 7 remaining items. Lastly, we tested the scale using participants from Amazon's ® …

An Evaluation Of The Utility Of At-Sat For The Placement Of New Controllers By Option, Cristina L. Byrne, Dana Broach Jan 2015

An Evaluation Of The Utility Of At-Sat For The Placement Of New Controllers By Option, Cristina L. Byrne, Dana Broach

International Symposium on Aviation Psychology - 2015

In this study, we investigated the utility and fairness of using the Air Traffic Selection and Training (AT-SAT) test battery to place Air Traffic Control Specialist (ATCS) applicants into terminal or en route facilities. While results of statistical analyses indicated that AT-SAT could be considered a valid tool for use in placement, based on technical considerations only, it was concluded that it should not be used in that way due to lack of utility and potential for adverse impact. If the FAA were to use AT-SAT for placement, the risk of additional adverse impact and pay disparities should be evaluated …

Identifying Mental Models Of Search In A Simulated Flight Task Using A Pathmapping Approach, Brandon S. Perelman, Shane T. Mueller Jan 2015

Identifying Mental Models Of Search In A Simulated Flight Task Using A Pathmapping Approach, Brandon S. Perelman, Shane T. Mueller

International Symposium on Aviation Psychology - 2015

Aerial assets are often used for missions such as intelligence, surveillance, target acquisition and reconnaissance. The pilot’s search decisions reflect a mental model for the search space, including characteristics such as target prioritization, distance-reward evaluations, and path optimization cri-teria. To investigate differences in these mental models, we examined 23 participants’ paths flown in a synthetic task environment in which they piloted a simulated aircraft to search for targets rep-resenting missing persons. Determining similarity among flight paths is a challenge. To accom-plish this, we used a new tool (Pathmapping, a package in the R statistical computing language; Mueller, Perelman, & Veinott, …

Faa Training Assessment Of On-The-Job Training, Darendia Mccauley Jan 2015

Faa Training Assessment Of On-The-Job Training, Darendia Mccauley

International Symposium on Aviation Psychology - 2015

The field training administered to air traffic controllers is provided by instructors who are also controllers but have undergone training to become on-the-job training instructors (OJTIs). The training of these field OJTIs is under revision based on a training needs assessment conducted in 2011. Controllers who were not successful in training at their first facility can be reassigned to another facility, where they receive field training specific to that facility. The controllers who did not succeed in training initially and requested reassignment may have a useful perspective on the training they received. This perspective may aid in revising the training …

Eeg Data Analysis Using Artifact Separation, Chelsey Credlebaugh, Matthew Middendorf, Michael Hoepf, Scott Galster Jan 2015

Eeg Data Analysis Using Artifact Separation, Chelsey Credlebaugh, Matthew Middendorf, Michael Hoepf, Scott Galster

International Symposium on Aviation Psychology - 2015

It has been postulated that physiological measures can be a positive indicator of mental workload. One such measure is the electroencephalogram (EEG). It is well known that the EEG signal is easily affected by artifacts. One prominent source of artifacts is eye activity, including blinks and saccades. These contaminates coincide directly with EEG signals, making it difficult to obtain artifact-free data. This paper discusses a methodology that performs artifact separation at the data analysis stage. This technique was used to analyze data from a recent experiment. Workload was manipulated by varying the difficulty of the primary task while responding to …

Enroute Atc Industry Perceptions Of Simulation Fidelity, Colin Dow, Jonathan Histon Jan 2015

Enroute Atc Industry Perceptions Of Simulation Fidelity, Colin Dow, Jonathan Histon

International Symposium on Aviation Psychology - 2015

Enroute air traffic control (ATC) relies heavily on simulation in training, research, and concept development applications. However, it has little domain-specific research on the effects of simulation fidelity and lacks a standardized definition of simulation fidelity in the literature. A survey of ATC industry professionals shows that simulation fidelity is not perceived to be well defined for the domain of enroute ATC, regardless of respondent nationality, experience, use of simulation or gender. Parts of the operational environment that survey respondents felt were important components in a definition of simulation fidelity are reported; Communications is the most important component regardless of …

Pilots’ Willingness To Report Aviation Incidents, Andreas Haslbeck, Carsten Schmidt-Moll, Ekkehart Schubert Jan 2015

Pilots’ Willingness To Report Aviation Incidents, Andreas Haslbeck, Carsten Schmidt-Moll, Ekkehart Schubert

International Symposium on Aviation Psychology - 2015

This paper reports results from a survey-based study among eighty-six airline pilots investigating their willingness to report safety-relevant events and incidents. Pilots have been asked to report how many events they have experienced in thirty-five different contextual areas and how often they have reported these cases. Thus, underreporting rates, respectively dark figures, were calculated and listed. These results and the willingness to report are discussed within an aviation operation’s background. Most of these surveyed underreporting rates are very high, which means a substantial source of uncertainty in airlines’ safety reporting databases, and thus for airlines’ safety management systems.

A Role For Folk Psychology In Animal Cognition Research, Kristin Andrews Jan 2015

A Role For Folk Psychology In Animal Cognition Research, Kristin Andrews

Experimentation Collection

If we consider that the field of animal cognition research began with Darwin’s stories about clever animals, we can see that over the 150 years of work done in this field, there has been a slow swing back and forth between two extreme positions. One extreme is the view that other animals are very much like us, that we can use introspection in order to understand why other animals act as they do, and that no huge interpretive leap is required to understand animal minds. On the other extreme we have the view that other animals are utterly different from …
