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

As part of a larger study examining relationships between taste properties and swallowing, we assessed the influence of genetic taster status (GTS) on measures of brain activity and swallowing physiology during taste stimulation in healthy men and women. Twenty-one participants underwent videofluoroscopic swallowing study (VFSS) and functional magnetic resonance imaging (fMRI) during trials of high-intensity taste stimuli. The precisely formulated mixtures included sour, sweet-sour, lemon, and orange taste profiles and unflavored controls. Swallowing physiology was characterized via computational analysis of swallowing mechanics plus other kinematic and temporal measures, all extracted from VFSS recordings. Whole-brain analysis of fMRI data assessed blood …

The Healing Power Of The Arts - Drama Therapy And The Use Of Theatre In The Treatment Of Trauma, Brooklyn Snyder

Student Scholar Symposium Abstracts and Posters

Theatre is an incredibly valuable therapeutic tool. In this thesis, I explore the ways in which trauma can reshape individuals lives, both cognitively and physically, impeding their sense of self, ability to trust, engagement, and many other seemingly ordinary aspects of day to day life that those of us unaffected by trauma take for granted. Additionally, I cover how employing theatrical tools, like improvisation and role play, can act as a beneficial treatment option for those who have suffered a traumatic past. Drama therapy allows individuals to reconnect with their bodies and their minds, gain new perspectives on their experiences, …

Human Milk Omega-3 Fatty Acid Composition Is Associated With Infant Temperament, Jennifer Hahn-Holbrook, Adi Fish, Laura M. Glynn

Psychology Faculty Articles and Research

There is growing evidence that omega-3 (n-3) polyunsaturated fatty-acids (PUFAs) are important for the brain development in childhood and are necessary for an optimal health in adults. However, there have been no studies examining how the n-3 PUFA composition of human milk influences infant behavior or temperament. To fill this knowledge gap, 52 breastfeeding mothers provided milk samples at 3 months postpartum and completed the Infant Behavior Questionnaire (IBQ-R), a widely used parent-report measure of infant temperament. Milk was assessed for n-3 PUFAs and omega-6 (n-6) PUFAs using gas-liquid chromatography. The total fat and the ratio of n6/n-3 fatty acids …

Huit, Grant Shulman, Jane L. Meza, Jolene Smyth, Nathan Woodruff, Richard Mocarski, Jae Puckett, Debra A. Hope

Trans Collaborations Academic Papers

One key aspect of evidence-based psychological services is monitoring progress to inform treatment decision making, often using a brief self-report measure. However, no such measure exists to support measurement based care given the distinct needs of transgender and gender diverse people (TGD), a group facing large documented health disparities and marginalization in healthcare. The purpose of the present study was to develop and provide initial psychometric validation of a short, behavioral health progress monitoring self-report measure, the Trans Collaborations Clinical Check-in (TC3). TGD communities, providers identified as TGD-affirmative, and relevant academic experts contributed to item and scale development. The final …

The Complex Relationship Between Celebrity-Driven Magazines And Depictions Of Fertility At Advanced Reproductive Ages, Brennan Peterson

Marriage and Family Therapy Faculty Articles and Research

"In this issue of the Journal of Women’s Health, Willson and colleagues explore how age and fertility are portrayed in celebrity-driven magazines.¹ Specifically, they examine if popular media depictions of celebrity pregnancies present accurate information related to age and fertility, the use of assisted reproductive technology (ARTs), and pregnancy-related risks associated with advanced maternal age (AMA >35 years). Their study provides an important viewpoint related to the impact of media on reproductive perceptions, and its potential intersection with delayed childbearing, fertility awareness, and reproductive decision making."

The Relationship Between Socioeconomic Status And White Matter Microstructure In Pre-Reading Children: A Longitudinal Investigation, Ola Ozernov-Palchik, Elizabeth S. Norton, Yingying Wang, Sara D. Beach, Jennifer Zuk, Maryanne Wolf, John D.E. Gabrieli, Nadine Gaab

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

Reading is a learned skill crucial for educational attainment. Children from families of lower socioeconomic status (SES) tend to have poorer reading performance and this gap widens across years of schooling. Reading relies on the orchestration of multiple neural systems integrated via specific white-matter pathways, but there is limited understanding about whether these pathways relate differentially to reading performance depending on SES background. Kindergarten white-matter FA and second-grade reading outcomes were investigated in an SES-diverse sample of 125 children. The three left-hemisphere white-matter tracts most associated with reading, and their right-hemisphere homologs, were examined: arcuate fasciculus (AF), superior longitudinal fasciculus …

Postoperative Pain: Factors And Tools To Improve Pain Management In Children, Mai M. Makhlouf, Eric Robles Garibay, Brooke N. Jenkins, Zeev N. Kain, Michelle Fortier

Psychology Faculty Articles and Research

Outpatient surgery has made it increasingly common for parents to manage pain in the home setting. Studies have shown that parents often under treat pain, leaving children vulnerable to the negative side effects of suboptimal pain management. Multiple factors affect pain management like child’s age and developmental stage, language, cultural values like stoicism, parental beliefs about medication, biological differences among groups, etc. Understanding all the factors involved can help healthcare providers and parents better understand pain and contribute to optimal pain management. Multiple tools and technological interventions have been created to help create a better understanding of pain and a …

An Integration-To-Bound Model Of Decision-Making That Accounts For The Spectral Properties Of Neural Data, Ramón Guevara Erra, Marco Arbotto, Aaron Schurger

Psychology Faculty Articles and Research

Integration-to-bound models are among the most widely used models of perceptual decision-making due to their simplicity and power in accounting for behavioral and neurophysiological data. They involve temporal integration over an input signal (“evidence”) plus Gaussian white noise. However, brain data shows that noise in the brain is long-term correlated, with a spectral density of the form 1/fα (with typically 1 < α < 2), also known as pink noise or ‘1/f’ noise. Surprisingly, the adequacy of the spectral properties of drift-diffusion models to electrophysiological data has received little attention in the literature. Here we propose a model of accumulation of evidence for decision-making that takes into consideration the spectral properties of brain signals. We develop a generalization of the leaky stochastic accumulator model using a Langevin equation whose non-linear noise term allows for varying levels of autocorrelation in the time course of the decision variable. We derive this equation directly from magnetoencephalographic data recorded while subjects performed a spontaneous movement initiation task. We then propose a nonlinear model of accumulation of evidence that accounts for the ‘1/f’ spectral properties of brain signals, and the observed variability in the power spectral properties of brain signals. Furthermore, our model outperforms the standard drift-diffusion model at approximating the empirical waiting time distribution.

The Unfolding Argument: Why Iit And Other Causal Structure Theories Cannot Explain Consciousness, Adrian Doerig, Aaron Schurger, Kathryn Hess, Michael H. Herzog

Psychology Faculty Articles and Research

How can we explain consciousness? This question has become a vibrant topic of neuroscience research in recent decades. A large body of empirical results has been accumulated, and many theories have been proposed. Certain theories suggest that consciousness should be explained in terms of brain functions, such as accessing information in a global workspace, applying higher order to lower order representations, or predictive coding. These functions could be realized by a variety of patterns of brain connectivity. Other theories, such as Information Integration Theory (IIT) and Recurrent Processing Theory (RPT), identify causal structure with consciousness. For example, according to …

We review the literature on team performance composites and briefly describe two approaches to developing evaluative performance composites in an academic setting by combining performance indicator data: A qualitative approach for performance feedback as well as an empirical approach for research purposes.

Examining Pilot Decision Making In Information-Rich Cockpits, Meredith Carroll, Donna Forsyth Wilt, Paige Sanchez, Deborah Carstens

International Symposium on Aviation Psychology - 2019

Pilots are faced with making decisions based on a range of different information sources. One challenge pilots often face is the presentation of conflicting information between sources. This effort examined pilot decision making with conflicting information by conducting structured interviews with 13 pilots, including seven airline, three corporate, and three GA pilots. Pilots were asked questions regarding their experience with conflicting sources of weather, traffic, and navigation information on the flight deck or cockpit. Further, they were asked to describe how they responded to the information conflict, including which source they trusted, which source they ultimately acted on, and why …

Understanding Current Ways Of Reporting Runway Incursion Incidents At Towered Airports, Divya Bhargava, Karen Marais

International Symposium on Aviation Psychology - 2019

Runway incursions occur when an unauthorized aircraft, vehicle or pedestrian operates on a runway. While most incursions are near-misses, they have the potential of turning into fatal accidents such as the Tenerife accident. Despite various efforts to reduce runway incursions, the number of incursions has been increasing. Learning from past incidents can help us develop effective preventive strategies but lack of in-depth investigations limits our understanding of the causes of incursions. At towered airports, the controller on duty reports the incident to the FAA using a form asking them to describe the incident in their own words. Our research question …

Individualized Landing Flare Training Using Both Flight Performance And Psychophysiological Measures, Jorg Onno Entzinger

International Symposium on Aviation Psychology - 2019

In this paper, we propose the analysis of various measures of eye and heart-rate data in addition to the flown trajectories and landing result, to get a better understanding of a trainee’s learning phase and optimize the time spent on and exercises used for the flare training. A problem often experienced is that the trainee knows what to do and tries to a level that (s)he even believes to be doing just that, without actually doing it. Objective, visual feedback can be used to provide the trainee with tangible points to focus on, instead of the often heard comments like …

Assessing Human-System Resilience Potential Throughout The Development Lifecycle*, Amy L. Alexander, Dan Herschler

International Symposium on Aviation Psychology - 2019

We worked with subject matter experts to create a human-system resilience checklist that can be utilized during Independent Operational Assessments (IOAs) of air traffic control systems as part of the system acquisition process. The checklist focuses on four key areas for evaluating human-system resilience characteristics: procedures, system use, workload, and training. A resilience scoring method indicates areas where a human-machine system under consideration does or does not have resilient characteristics. Overall resilience scores can be compared among design alternatives, or across different points in system development for a particular design. The ultimate intent is to provide guidance and metrics that …

The Nasa Matb-Ii Predicts Prospective Memory Performance During Complex Simulated Flight, Kathleen Van Benthem, Caitlin Shanahan, Chunyun Ma, Adam Fraser, Chris M. Herman

International Symposium on Aviation Psychology - 2019

Prospective memory is essential for flight, where failures can result in incorrect flight control settings, leading to loss of life and equipment. Furthermore, prospective memory is highly-sensitive to pilot age, cognition, and experience. This research reports on the relation of the NASA Multi-Attribute Test Battery-II (MATB-II) to prospective memory during simulated VFR flight (N=51). Prospective memory was indexed with specialized radio calls that were associated with non-focal visual cues. Linear regression models examined the relative association of MATB-II variables to prospective memory in low and high workloads. System monitoring, psychomotor tracking, and resource management, generally at higher difficulty levels, were …

Actual previous extreme weather incidences are used. Testing of the platform is ongoing with ATC students from Kent State University. Data from subjective pre- and postquestionnaires as well as objective decision parameters are currently …

Resilience And Safety For In-Time Monitoring, Prediction, And Mitigation Of Emergent Risks In Commercial Aviation, Jon Holbrook, Lawrence J. Prinzell Iii, Michael J. Stewart, Brian E. Smith, Bryan L. Matthews

International Symposium on Aviation Psychology - 2019

Safety in aviation has been historically defined in terms of the occurrence of accidents or recognized risks; that is, safety is typically defined in terms of things that go wrong. An alternative and complementary approach is to focus on what goes right, and identify how to make that happen again. Focusing on the rare cases of failures attributed to “human error” provides little information about why human performance almost always goes right. Similarly, focusing on the lack of safety provides limited information about how to improve safety. This work builds upon a growing literature on resilience engineering and new approaches …

This paper focuses on enhancements to support the effective use of the Pre- Departure ReRoute tool (PDRR). These enhancements emphasize the importance of integration …

Pilot Wellbeing & Work Related Stress (Wrs), Joan Cahill, Paul Cullen, Keith Gaynor

International Symposium on Aviation Psychology - 2019

This paper presents the preliminary findings of an anonymous web-based survey addresing pilot work related stress (WRS) and wellbeing. The initial analysis indicates that pilots are under stress and experiencing wellbeing problems. Specific features of the job can result in wellbeing problems, spanning the three pillars of wellbeing. Critically, sources of WRS can increase a pilot’s risk in terms of developing a mental health (MH) issue. Further, sources of WRS can impact on performance and safety. Considerable barriers still remain in relation to reporting MH issues at work. Coping mechanisms addressing sleep/fatigue, diet, exercise and communication/reporting, enable some pilots to …

Towards A Meta-Model To Specify And Design Human-Agent Teams, Michael F. Schneider, Michael E. Miller, John M. Mcguirl

International Symposium on Aviation Psychology - 2019

This paper describes work towards developing a meta-model useful in the design and specification of Human-Agent Teams. The meta-model adapts components from the cognitive systems, human factors, software and systems engineering literature to form a model and language which can be applied early in the system design process. The resulting model provides a description of desired system behavior. More importantly, the model produces artifacts useful in deriving requirements for both the human and the artificial agents, as well as for the software/hardware human interface. Insight is also provided for manpower, training, and personnel requirements; as well as, requirements for agent …

Development Of An Integrated Unmanned Aerial Systems Validation Center, Austin G. Decker, John H. Mott, Robert J. Connor, Ayman Habib, Darcy M. Bullock

International Symposium on Aviation Psychology - 2019

Unmanned Aerial Systems (UAS) have the potential to drastically change how civil infrastructure is inspected, monitored, and managed. Deployment of UAS in areas such as bridge inspection and accident reconstruction will likely have far-reaching impacts and evolve over time, with new uses and users emerging as technology matures. However, with any new technology, limitations exist until new protocols are established, and industry must move forward with an appropriate level of caution. For example, statements regarding the ability of a UAS to replace a human bridge inspector are frequently observed in trade magazines, presentations, and in the literature, though no objective …

Communicating Data-Driven Risk Information To Pilots, Nicoletta Fala, Karen Marais

International Symposium on Aviation Psychology - 2019

General Aviation safety is a pressing concern. In this research, we consider the factor that appears most often in accidents: the pilot. Newly-licensed pilots can fly without their instructor, potentially as the only or most experienced pilot in the aircraft. Commercial debrief products use technology in the flight deck to collect data and provide post-flight visualizations for performance reviews, but do not discuss flight safety. To manage risk, though, pilots need to perceive the risk associated with a situation before deciding whether they are willing to accept it. Safety-driven post-flight feedback may help address performance. However, it is not clear …

Feedback On The Use Of Matb-Ii Task For Modeling Of Cognitive Control Levels Through Psycho-Physiological Biosignals, Yannick Daviaux, Christophe Bey, Laurent Arsac, Olivier Morellec, Sami Lini

International Symposium on Aviation Psychology - 2019

Modeling individuals’ cognitive control levels in operational situations is a major challenge for safety in aeronautical industry. Standardized experimental tasks - as the Multi-Attribute Task Battery II (MATB-II) - are dedicated to such a challenge that can be faced using psycho-physiological biosignals. These biosignals are known to be sensitive to cognitive workload, performance, and expertise that are intricate features of MATB-II subtasks. Thus, it remained necessary to investigate whether these features could be set to ensure controlled experimental conditions. Two groups (15 experts in time-pressured decision making and 13 novices) completed 3 MATB-II sub-tasks (tracking, monitoring, and resource management tasks). …

Aviation English Listening And Repeating Task For Native English Speaker And Non-Native English Speaker Pilots, Julia Trippe

International Symposium on Aviation Psychology - 2019

Aviation English, based on a coded jargon from World War II, is a mandatory form of communication for pilots and controllers in international airspace. The International Civil Aviation Organization also requires proficiency in Conversational English, for use in non-standard communication. However, our past research indicates that Aviation English and Conversational English are distinct varieties of English, suggesting that assumptions about native English speaker proficiency and additive learning for non-native English speakers may be false. To establish how different these language varieties are, we present a study of Aviation English intelligibility for non-native and native English speaking pilots. Results suggest that …

Evaluation Of Uas Operator Training During Search And Surveillance Tasks, Pratusha Reddy, Dale Richards, Hurtulus Izzetoglu

International Symposium on Aviation Psychology - 2019

Unmanned aircraft system (UAS) sensor operators are typically required to execute search and surveillance tasks. Brain-in-the-loop measures during such tasks can help evaluate expertise development and cognitive capacities of the operator, which can be an important asset in designing adaptive and personalized training systems. Emergence of functional near infrared spectroscopy (fNIRS) has enabled monitoring of operators’ prefrontal cortex (PFC) area, which is associated with higher level cognitive functioning such as decisionmaking, problem-solving, working memory and attention in everyday working environments. In a previous sensor operator training study, we investigated and reported preliminary evidence suggesting that fNIRS measures acquired from the …
