The Electrooculogram And A New Blink Detection Algorithm, Samantha L. Epling, Matt Middendorf, Michael Hoepf, Christina Gruenwald, Lucas Stork, Scott Galster
International Symposium on Aviation Psychology - 2015
Accurate and efficient real-time cognitive workload assessment has many important applications, and physiological monitoring has proven quite helpful with this assessment. One such physiological signal, the electrooculogram (EOG), can provide blink rate and blink duration measures. In a recent study, we developed and validated a robust blink detection algorithm based on the vertical EOG (VEOG). This algorithm does not require baseline data and is adaptive in the sense that it works for a wide variety of individuals without any experimenter adjustments. The performance of the algorithm is quantified using truth data based on video recordings. The algorithm produced blink rate …
Eeg Data Analysis Using Artifact Separation, Chelsey Credlebaugh, Matthew Middendorf, Michael Hoepf, Scott Galster
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 …
Flight Operational Quality Assurance (Foqa) – Do Exceedances Tell The Story?, Brian G. Dillman, Dennis Wilt, Shawn Pruchnicki, Mark Ball, Marshall Pomeroy
Flight Operational Quality Assurance (Foqa) – Do Exceedances Tell The Story?, Brian G. Dillman, Dennis Wilt, Shawn Pruchnicki, Mark Ball, Marshall Pomeroy
International Symposium on Aviation Psychology - 2015
The concept of Flight Operational Quality Assurance (FOQA) programs have been widely utilized throughout the aviation industry. The premise behind the concept is to establish thresholds for flight situations based upon company operations specifications, regulatory guidance, aircraft limitations, and standard operating procedures and then monitor performance on the aggregate to determine if operations fall within acceptable boundaries. A singular exceedance may not trigger corrective actions, but if overall exceedances for the company exceed a predetermined acceptable threshold then mitigation strategies are employed to bring performance back within acceptable limits. Does this tell the whole story? Would allowing feedback for performance …
Faa Training Assessment Of On-The-Job Training, Darendia Mccauley
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 …
A Regression Of Consumer Atttitudes Toward Airport Water Reuse, Ismael Cremer, Stephen Rice, Scott R. Winter
A Regression Of Consumer Atttitudes Toward Airport Water Reuse, Ismael Cremer, Stephen Rice, Scott R. Winter
International Symposium on Aviation Psychology - 2015
Recent studies have focused on characterizing and understanding the public’s perceptions of risk with respect to general reuse projects (Baggett, Jefferson & Jefferson 2005; Hurlimann 2011; Toze, 2005). These studies have shown varying attitudes toward water reuse and are necessary to assess the public’s risk perception and acceptance of water reuse before implementing it. To date, no studies have examined whether certain variables affect people’s attitudes toward the water reuse concepts at airports. Four hundred and four participants from India and the United States participated in a study wherein various socio-economic were collected along with their attitude scores toward water …
Evaluating Startle, Surprise, And Distraction: An Analysis Of Aircraft Incident And Accident Reports, Andrew B. Talone, Javier Rivera, Camilo Jimenez, Florian Jentsch
Evaluating Startle, Surprise, And Distraction: An Analysis Of Aircraft Incident And Accident Reports, Andrew B. Talone, Javier Rivera, Camilo Jimenez, Florian Jentsch
International Symposium on Aviation Psychology - 2015
Over the years, startle, surprise, and distraction have been frequently cited as potentially having negative effects on aircraft flightcrew performance. This paper aims to build upon and extend our prior research (Rivera, Talone, Boesser, Jentsch, & Yeh, 2014) in which we found evidence that (a) startle may be less problematic to flight deck performance than surprise, and (b) negative flight deck performance following startle is most likely due to concurrent distraction or surprise. The current research examined the theoretical foundations underlying these concepts and analyzed two accident/incident databases to identify potential trends and assess the prevalence of startle, surprise, and …
Incorporating New Methods Of Classifying Domain Information For Use In Safety Hazard Analysis, Nancy G. Leveson, Daniel R. Montes, Leia A. Stirling
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 …
Statistical Errors In Aviation Psychology: Commonsense Statistics In Aviation Safety Research, Christopher D. Wickens
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 …
Experimental Evaluation Of Varying Feedback Of A Cognitive Agent System For Uav Mission Management, Elisabeth Denk, Sebastian Clauss, Annike Borchers, Josef Werner, Axel Schulte
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 …
Procedure Used For Establishing Screening Test Cut-Points Based On Aviation Occupational Task Performance, Nelda Milburn, Thomas Chidester, Kevin Gildea, Linda Peterson, Carrie Roberts, Deborah Perry
Procedure Used For Establishing Screening Test Cut-Points Based On Aviation Occupational Task Performance, Nelda Milburn, Thomas Chidester, Kevin Gildea, Linda Peterson, Carrie Roberts, Deborah Perry
International Symposium on Aviation Psychology - 2015
Previous research has shown that some individuals with color vision deficiencies (CVD) are capable of performing some aviation occupational tasks as well as those with normal color vision (NCV); implying that passing a screening test with a diagnosis of NCV may not be necessary for all aviation occupations. Our goal was to find outcome consistency between performance on occupational tasks and several screening tests; further, to compare those pass/fail outcomes to the Colour Assessment and Diagnosis (CAD) test for aviation certification. The strategy involved establishing a pass/fail cut-point separately for four occupational tasks at the 5th percentile of the NCV …
Assessing Potential Human Performance Safety Impacts Associated With Integrating Multiple Time-Based Flow Management Concepts, Michael W. Sawyer, Katherine A. Berry, Devin Liskey, Richard Rohde
Assessing Potential Human Performance Safety Impacts Associated With Integrating Multiple Time-Based Flow Management Concepts, Michael W. Sawyer, Katherine A. Berry, Devin Liskey, Richard Rohde
International Symposium on Aviation Psychology - 2015
Time-Based Flow Management (TBFM) seeks to enhance system efficiency by improving scheduling and interval management tools that expand and enhance the flow of traffic. This paper presents the results of an integrated human performance safety assessment of TBFM concepts planned for implementation between 2016 and 2020. The assessment utilized the Human and Organizational Safety Technique (HOST) to provide a structured method for identifying potential human error modes and estimating their contribution to the risk profile. HOST further defined graphical human-system interaction models for each proposed change and an integrated interaction model across all assessed TBFM changes. The HOST assessment resulted …
The Effects Of Workload And Stress On Teamwork In A High Fidelity Simulation, Andrea M. Georgiou
The Effects Of Workload And Stress On Teamwork In A High Fidelity Simulation, Andrea M. Georgiou
International Symposium on Aviation Psychology - 2015
With a unique high fidelity simulation lab, participants completed 3 hour work shifts to a run a simulated regional airline. The experimental design consisted of three teams randomly assigned to either a minimal, moderate, or maximum level of difficulty. Increases in workload and stress were implemented with various triggers and the participants had to quickly develop solutions to mitigate the problems. After the simulation, the participants completed the CATME (Comprehensive Assessment of Team Member Effectiveness) online survey for evaluations of their performance for five variables. (Ohland et al., 2012). Based on one-way analysis of variance (ANOVA), the results suggest only …
Development Of An Alternative Methodology For Implementation Of Sagat During Task Performance, Durant C. Bridges
Development Of An Alternative Methodology For Implementation Of Sagat During Task Performance, Durant C. Bridges
International Symposium on Aviation Psychology - 2015
Situation awareness (SA) has been linked to performance in a variety of disciplines to date, but originated in the aviation arena. Situation awareness derives from attention and working memory being used toward acquiring and interpreting information from the environment (Endsley, 1995). The most revered objective method of measuring situation awareness is the Situation Awareness Global Assessment Technique (SAGAT). This technique employs random freezes of participant interfaces during simulations to query participants and assess the level of knowledge of what is happening at the time of the freezes. A discussion of applications using an alternative approach to SAGAT for operators in …
Psychological Aspects Of The Organization Of Information At The Instructor’S Flight Simulator Workplace, Tetiana Bondareva
Psychological Aspects Of The Organization Of Information At The Instructor’S Flight Simulator Workplace, Tetiana Bondareva
International Symposium on Aviation Psychology - 2015
This Paper presents a critical analysis of the classical procedure of training pilots on Full Flight Simulators (FFS), and developed new version of the procedure of instructor’s actions during simulator training. The developed procedure will change an instructor’s position as person, who sets parameters before and during performing exercise, to a person as involved participant, who is waiting for a forthcoming training flight circumstances together with the crew. This developed procedure implies a rearrangement of specific operations from the instructor on the software, and also the availability of an alternative monitor, on which the most significant events (selected for specific …
A Comprehensive Effort To Arrive At An Optimally Reliable Human Factors Taxonomy, Raymond E. King
A Comprehensive Effort To Arrive At An Optimally Reliable Human Factors Taxonomy, Raymond E. King
International Symposium on Aviation Psychology - 2015
Department of Defense (DoD) members sought to improve the inter-rater reliability of the DoD Human Factors Analysis and Classification System, (DoDHFACS). DoDHFACS differs from the original system developed by Wiegmann and Shappell (2003), based on the work of Reason (1990), by further analyzing mishaps and hazards to a more granular level – arriving at specific “nanocodes.” The steps involved in the effort included determining which of the 147 “nanocodes” were rarely/never used and collapsing nanocodes and rewriting definitions to arrive at 109 nanocodes. Next, a stepwise checklist to guide investigators through consideration of nanocodes was created. Student investigators were guided …

Investigating Uas Operator Characteristics Influencing Mission Success, Haydee M. Cuevas, Kristina M. Kendrick, Zane A. Zeigler, David J. Hamilton
International Symposium on Aviation Psychology - 2015
The two objectives of this study were to 1) evaluate how specific operator characteristics (prior experience in manned and unmanned flight, teamwork, and gaming) influence mission success in unmanned aircraft systems (UAS) operations; and 2) evaluate the potential utility of a performance assessment tool. Mission success was assessed using a modified version of the Situation Awareness Linked Indicators Adapted to Novel Tasks (SALIANT) methodology. Eighteen participants completed a UAS scenario (port security) as part of 9 two-person crews (pilot and sensor operator). Results showed that the SALIANT measure was able to discriminate differences in performance among the UAS crews. Results …
