Training Manned-Unmanned Teaming Skills In Army Aviation, Susan R. Flaherty, Martin L. Bink

International Symposium on Aviation Psychology - 2015

Current Army Aviation combat operations utilize an employment strategy that teams a rotary wing aircraft with an unmanned aircraft system (UAS), thereby leveraging strategic advantages of each aircraft’s unique capabilities, endurance, and payloads. Clear and effective communications between the airborne helicopter pilot and the ground-based UAS operator are critical for successful Manned-Unmanned Teaming (MUM-T) missions. Previous studies have recommended additional training in tactical communications for the UAS payload operator in order to support precision and timeliness in teaming engagements. In accordance with Army Learning Model 2015, an engaging, skills-adaptive, computer game was developed to train critical MUM-T skills for the …

Saccade Detection Using Polar Coordinates – A New Algorithm, Matt Middendorf, Christina Gruenwald, Lucas Stork, Samantha Hoepf, Scott Galster

International Symposium on Aviation Psychology - 2015

Over the past few decades substantial research has been conducted regarding saccades (rapid eye movements). There are two components of this research. First there is the detection of the saccades, and second how to interpret the saccades features (amplitude, length, and velocity) to inform specific areas of research. This involves both experimental research and clinical applications. The detection of saccades is typically accomplished using two approaches, including cameras and the electrooculogram (EOG). Both of these approaches require algorithms to process the raw data, detect saccades, and calculate the saccade features. The current effort focuses on detecting saccades in the EOG …

Conceptual And Procedural Training For Situation Awareness And Performance In An Instrument Holding Task, Andrew R. Dattel, Jennifer E. Thropp

International Symposium on Aviation Psychology - 2015

An exploratory approach that investigated the differences between conceptually and procedurally trained participants in situation awareness (SA) and performance of instrument holds was conducted. The step-by-step actions required to fly instrument holds were emphasized in the procedural training group. The interrelationship of elements in a dynamic environment was emphasized in the conceptual group. Participants were tested in two simulated instrument holding pattern scenarios. The second holding pattern was designed to be more complex. A trend was found where the conceptual group showed less altitude deviation (M = 399.22) than the procedural group (M = 599.74). Participants were asked six SA …

Effect Of Control Latency On Unmanned Aircraft Systems During Critical Phases Of Flight, Carolina M. Zingale, Eric G. Taylor

International Symposium on Aviation Psychology - 2015

Unmanned Aircraft Systems (UAS) are controlled remotely via terrestrial or satellite-based radio link rather than by a pilot in the cockpit. The remote nature of the transmission results in latencies (time between pilot input and feedback indicating aircraft response) that are typically longer than those in manned aircraft. Researchers from the FAA Human Factors Branch conducted a simulation to investigate the effect of control latencies during takeoff and landing scenarios in UAS with low levels of automation. We evaluated one of four latencies (180, 494, 750, 1026 ms) in each test scenario. Half of the scenarios included crosswinds. Data obtained …

Toward A Human Performance Standard Of Excellence In Air Traffic Management, Paul Krois, Damien Armenis, Rémi Joly, Barry Kirwan, Claire Marrison, Neil May, Dino Piccione, Michaela Schwarz

International Symposium on Aviation Psychology - 2015

Air Traffic Management (ATM) is a 24/7 industry that strongly depends on people and needs its frontline staff to be on top performance to maintain safety and efficiency of the air transport system. However, Air Navigation Service Providers (ANSPs) too often downplay the integration of human performance against higher priority operational and business issues. At the same time, human factors experts are sometimes challenged in communicating their tools and methods in ways that are seen as pertinent to ANSP issues. In order to bridge these organizational stove pipes, an international approach is being harmonized for ANSPs to gauge their maturity …

Which Methods Of Treating Attention Deficit Hyperactive Disorder Are Most Effective And Most Closely Match Patient Lifestyle?, Yehudit Erlbaum

The Science Journal of the Lander College of Arts and Sciences

ADHD, attention deficit hyperactive disorder, is a disorder characterized by hyperactivity, inattentiveness, inability to remain on task, fidgetiness, and impulsivity. An over absorption of dopamine by the dopamine transporters leads to a lack of dopamine, the inhibiting neurotransmitter in the brain, resulting in the inability for the individual to inhibit their impulses. The disease is most likely seen in children but may continue into adulthood. The length of the disease across the individual’s life span, results in expensive treatment, whether it be medication or Cognitive Behavior Therapy, CBT. Therefore, these medical costs have caused researchers to find the most efficient …

Neuroimaging And Neuromodulation Approaches To Study Eating Behavior And Prevent And Treat Eating Disorders And Obesity, D. Val-Laillet, E. Aarts, B. Weber, M. Ferrari, V. Quaresima, L. E. Stoeckel, M. Alonso-Alonso, M. Audette, C. H. Malbert, E. Stice

Computational Modeling & Simulation Engineering Faculty Publications

Functional, molecular and genetic neuroimaging has highlighted the existence of brain anomalies and neural vulnerability factors related to obesity and eating disorders such as binge eating or anorexia nervosa. In particular, decreased basal metabolism in the prefrontal cortex and striatum as well as dopaminergic alterations have been described in obese subjects, in parallel with increased activation of reward brain areas in response to palatable food cues. Elevated reward region responsivity may trigger food craving and predict future weight gain. This opens the way to prevention studies using functional and molecular neuroimaging to perform early diagnostics and to phenotype subjects at …

The Evolving Role Of Dendritic Spines And Memory: Interaction(S) With Estradiol, M. Frankfurt, V. Luine

Journal Articles

This article is part of a Special Issue "Estradiol and Cognition". Memory processing is presumed to depend on synaptic plasticity, which appears to have a role in mediating the acquisition, consolidation, and retention of memory. We have studied the relationship between estrogen, recognition memory, and dendritic spine density in the hippocampus and medial prefrontal cortex, areas critical for memory, across the lifespan in female rodents. The present paper reviews the literature on dendritic spine plasticity in mediating both short and long term memory, as well as the decreased memory that occurs with aging and Alzheimer's disease. It also addresses the …

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 …

Generalised Anxiety Disorder – A Twin Study Of Genetic Architecture, Genome-Wide Association And Differential Gene Expression, Matthew N. Davies, Serena Verdi, Andrea Burri, Maciej Trzaskowski, Minyoung Lee, John M. Hettema, Rick Jansen, Dorret I. Boomsma, Tim D. Spector

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

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 …

To investigate the time dependence of sodium nitroprusside- (NPS-) induced oxidative effects, the authors study the variation of the antioxidant enzyme CAT activity in various tissues after the administration of a single 2.5mg/kg dose of SNP or sodium chloride (NaCl 0.9%). For each of the two dosing times (1 and 13 hours after light onset, HALO, which correspond to the beginning of diurnal rest span and of nocturnal activity span of mice, resp.), brain, kidney, and liver tissues were excised from animals at 0, 1, 3, 6, 9, 12, 24, and 36 h following the drug administration and CAT activity …

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

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

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

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

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 …
