The Combination Of Cooling Techniques In A Tropical Environment Improves Precision Performance In Young International Fencers, Aurélie Collado, Nicolas Robin, Stéphane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

The performance of intense exercise in a tropical climate is associated with limited exercise capacity due to thermal strain. This limitation is exacerbated in sports requiring full protective equipment. Research evidence suggests disturbances in cognitive function due to thermal discomfort and/or protective equipment (e.g., helmets), and thus sports that require skills in decision-making, fast reaction times, precision, and/or inhibition can be greatly affected. The objective of this study was to investigate the effects of countermeasures on the psychological and physiological responses in young international fencers wearing full protective equipment during an ecological fencing task. Nine young international fencers performed an …

Using An Approach-Avoidance Framework To Understand The Relationship Between Non-Lethal Weapons And Performance, Andrew J. Mojica, Christopher P. Bartak, Joseph N. Mitchell, Alan Ashworth

Journal of Human Performance in Extreme Environments

It is proposed that performance degradation from exposure to non-lethal technology is mediated by impulsive and reflective approachavoidance motivation. An approach-avoidance motivational framework was used to specify a four-stage information processing model that predicts performance degradation. The first stage is Evaluation: it processes physiological, sensory, perceptual, and cognitive information. The second stage is Comparison: it processes the content of the Evaluation into avoidance and approach motivational indices. The third stage is Probability: it processes information from previous stages into a probability of choosing to continue or abandon goal-directed behavior. Finally, the fourth stage is Performance: it processes performance accuracy on …

Constraining The Binding Problem Using Maps, Zhixian Han, Anne Sereno

MODVIS Workshop

We constrained the binding problem by creating maps of different attributes. We compared the performance of different models with different maps in our current study. Our preliminary results showed that the performance of the model is the highest when location maps were used. These results suggest that the optimal way to constrain the binding problem is to create location maps of different attributes.

Rim-To-Rim Wearables At The Canyon For Health (R2r Watch): Physiological, Cognitive, And Biological Markers Of Performance Decline In An Extreme Environment, Kristin Divis, Robert Abbott, Cathy Branda, Glory Emmanuel-Aviña, Jon Femling, J. Gabriel Huerta, Lucie Jelinková, J. Kyle Jennings, Emily A. Pearce, Daniel Ries, Danielle Sanchez, Austin Silva

Journal of Human Performance in Extreme Environments

Success in extreme environments comes with a cost of subtle performance decrements that if not mitigated properly can lead to lifethreatening consequences. Identification and prediction of performance decline could alleviate deleterious consequences and enhance success in challenging and high-risk operations. The Rim-to-Rim Wearables at the Canyon for Health (R2R WATCH) project was designed to examine the cognitive, physiological, and biological markers of performance decline in the extreme environment of the Grand Canyon Rim-to-Rim (R2R) hike. The study utilized commercial off-the-shelf cognitive and physiological monitoring techniques, along with subjective self-assessments and hematologic measurements to determine subject performance and changes across the …

Identifying And Localizing Multiple Objects Using Artificial Ventral And Dorsal Visual Cortical Pathways, Zhixian Han, Anne Sereno

MODVIS Workshop

We concluded in our previous study that model cortical visual pathways actively retained information differently according to the different goals of the training tasks. One limitation of our study was that there was only one object in each input image whereas in reality there may be multiple objects in a scene. In our current study, we try to find a brain-like algorithm that can recognize and localize multiple objects.

Cognitive Offloading Strategies And Decrements In Learning: Lessons From Aviation And Aerospace Crises, D. Christopher Kayes, Jeewhan Yoon

Journal of Human Performance in Extreme Environments

Examples from aviation and aerospace illustrate the potential consequences that emerge when organizations replace learning from experience with technology, a process referred to as a cognitive offloading strategy (COS). Examples include the Air France Flight 447 crash involving an Airbus 330-203 and the Lion Air Flight 610 crash involving a Boeing 737 Max. From the perspective of human performance in extreme environments, COS represents an underexplored source of organizational vulnerability which presents a particular challenge for learning in organizations. Decrements in learning result from COS because COS creates gaps in procedural knowledge and deprives operators of opportunities to learn in …

A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal

Journal of Human Performance in Extreme Environments

In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …

The Influence Of Tropical Climate On Cognitive Task Performance And Aiming Accuracy In Young International Fencers, Nicolas Robin, Aurelie Collado, Stephane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

This study examined how a tropical climate (TC) influences the cognitive and aiming task performances of young international fencers. The participants performed the tasks in TC and an air-conditioned room. In each session, they completed questionnaires evaluating affective states, fatigue, and comfort and thermal sensations. They also carried out cognitive tasks (simple and choice reaction time, attention, and vigilance tasks) and a motor task testing aiming accuracy with a sword while wearing protective clothing and a mask. TC, which was observed to decrease thermal discomfort, was revealed to decrease aiming accuracy and positive affective states. There was no deleterious effect …

Recovering Depth From Stereo Without Using Any Oculomotor Information, Tadamasa Sawada

MODVIS Workshop

The human visual system uses binocular disparity to perceive depth within 3D scenes. It is commonly assumed that the visual system needs oculomotor information about the relative orientation of the two eyes to perceive depth on the basis of binocular disparity. The necessary oculomotor information can be obtained from an efference copy of the oculomotor signals, or from a 2D distribution of the vertical disparity, specifically, from the vertical component of binocular disparity. It is known that oculomotor information from the efference copy and from the vertical disparity distribution can affect the perception of depth based on binocular disparity. But, …

Impact Of Tropical Climate On Selective Attention And Affect, Guillaume R. Coudevylle, Maria Popa-Roch, Stéphane Sinnapah, Olivier Hue, Nicolas Robin

Journal of Human Performance in Extreme Environments

Heat has an impact on several aspects of human cognition but the effects of the tropical climate (i.e., hot and wet) have rarely been explored. The purpose of this study was to determine whether selective attention and affect are negatively impacted by the tropical climate. The study followed a within-participants design: participants responded to an affective scale (PANAS) and performed an attention task (d2 Test) in two experimental climate conditions (tropical vs. neutral) with a one-week interval between sessions. The results indicated that they had lower positive affect and selective attention in the tropical climate than in the neutral climate. …

Physiological And Cognitive Factors Related To Human Performance During The Grand Canyon Rim-To-Rim Hike, Kristin Divis, Clifford Anderson-Bergman, Robert Abbott, Victoria Newton, Glory Emmanuel-Aviña

Journal of Human Performance in Extreme Environments

Exposure to extreme environments is both mentally and physically taxing, leading to suboptimal performance and even life-threatening emergencies. Physiological and cognitive monitoring could provide the earliest indicator of performance decline and inform appropriate therapeutic intervention, yet little research has explored the relationship between these markers in strenuous settings. The Rim-to-Rim Wearables at the Canyon for Health (R2RWATCH) study is a research project at Sandia National Laboratories funded by the Defense Threat Reduction Agency to identify which physiological and cognitive phenomena collected by non-invasive wearable devices are the most related to performance in extreme environments. In a pilot study, data were …

Modeling Distribution Learning In Visual Search, Andrey Chetverikov

MODVIS Workshop

Chetverikov, Campana, and Kristjansson (2017) used visual search to demonstrate that human observers are able to extract statistical distributions of visual features. Observers searched for an odd-one-out target with distractors randomly drawn from the same distribution over the course of several “prime” trials. Then, on test trials parameters of the target and distractors changed and response times (RT) were analyzed as a function of the distance between the target position in feature space and the mean of distractor features during prime trials. The resulting RT curves followed the probability density of prime distractor distributions. This approach provides a detailed estimation …

Modeling The Neural Circuitry Underlying The Behavioral And Eeg Correlates Of Attentional Capture, Chloe Callahan-Flintoft, Brad Wyble

MODVIS Workshop

The Reactive-Convergent Gradient Field model (R-CGF) is a unique approach to modeling spatial attention in that it links neural mechanisms to event related potentials (ERPs) from scalp EEG. This model was developed with the aim of explaining different, sometimes conflicting, findings in the attention literature. Specifically, this model address conflicting findings showing both simultaneous and serial deployment of attention. Another argument addressed by the model is whether attention to a location invokes a suppression of the spatial surround, or the selective inhibition of distractors. With the R-CGF, we have found that these results are not as incompatible as they appear …

Teoria De La Mente Y Sociedad En La Narrativa Policiaca De Lorenzo Silva Y Francisco Garcia Pavon: Estereotipos, Roles De Genero Y Minorias, Jesus Castro Gorfti

Open Access Dissertations

Spanish:

The purpose of this study is to utilize certain aspects of cognitive psychology as a framework to analyze the police procedural novels of two Spanish authors: Francisco García Pavón and Lorenzo Silva. Specifically, we will focus on two main aspects of the mind studied by the cognitive sciences: Theory of Mind and metarepresentations. Theory of Mind (ToM) refers to the capacity that human beings have to attribute mental states to other humans, as well as oneself, based on their bodily and facial gestures. The concept of metarepresentation refers to the ability of humans to keep track of who said …

Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers

Open Access Theses

Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting that these …

The Effects Of Including Almonds In An Energy-Restricted Diet On Weight, Body Composition, Visceral Adipose Tissue, Blood Pressure And Cognitive Function, Jaapna Dhillon

Open Access Dissertations

Inclusion of almonds in an energy restricted diet has been reported to enhance or have no effect on weight loss. Their effects specifically on visceral fat stores during energy restriction have not been widely examined. Additionally, almond consumption has been associated with reduced blood pressure, but whether this is linked to or is independent of changes of body composition has not been examined. Moreover, almond consumption during energy restriction may be an effective strategy for reversing the negative effects of dieting on cognitive performance. The unique nutrient profile of almonds also has the potential to influence cognitive function post-prandially. The …

L2 Effect On Bilingual Spanish/English Encoding Of Motion Events: Does Manner Salience Transfer?, Heidi E. Parker

Open Access Dissertations

This study explores the potential effect of a second language (L2) on first language (L1) encoding of motion events. The domain of interest is MANNER and the goal is to investigate if the degree of manner salience can be restructured under the effect of a L2. Slobin (2004, 2006) proposes an expansion of Talmy’s (1985, 1991, 2000) binary typology and observes that the degree of manner saliencevaries cross-linguistically. The two languages investigated in this study, Spanish and English, are at divergent points along the cline of manner salience. In addition, Slobin (1996b) suggests dividing MANNER into tier one (T1) …

Exploring Animacy As A Mnemonic Dimension, Joshua Edward Vanarsdall

Open Access Dissertations

There is a great deal of evidence across cognitive science that animacy, or more generally, the features that make up what it means to be a living thing, is a foundational dimension of human cognition. In perception, animates both capture attention (Pratt, Radulescu, Guo, & Abrams, 2010) and are relatively immune to change blindness (New, Cosmides, & Tooby, 2007). Developmental work places the animate-inanimate distinction as one of the first categories children learn (Opfer & Gelman, 2011). Work in neuroscience points toward a fundamental role for animacy in semantic memory (Caramazza & Mahon, 2003), and linguists have identified animacy as …

Measure Athletes’ Volition—Short: Evidences For Construct Validity And Reliability, Ioannis Proios, Miltiadis Proios

Journal of Human Performance in Extreme Environments

The Measure Athletes’ Volition consists of 23 items that measure six elements of volitional competences. The purpose of the present study was to examine whether a subset of these items could form a short version of the scale; to provide evidence for the structural validity and internal consistency of the short version; and to test validity issues of the new scale. A total of 831 individuals from three different samples completed the long version of the scale. Results indicated that the short version consisted of 15 items that measured volitional competences of persistence, expediency, and purposefulness. This scale had acceptable …

Creativity In Organizations: Antecedents And Outcomes Of Individual Creativity, Goran Calic

Open Access Dissertations

In this dissertation I set out to expand our collective understanding of creativity in organizations. I accomplish this through three related studies, each organized into independent chapters of this dissertation.

The first study explores how demands of organizations, particularly strategic contradictions faced by decision makers, affect creative processes and products. In this chapter I develop the theory of paradoxical creativity, which posits that creative discovery is a function of how strategic contradictions are perceived by decision-makers. The key insight of the theory of paradoxical creativity is that strategic contradictions have independent effects on the two stages of creative discovery (generation …

Learning The Language Of Academic Engineering: Sociocognitive Writing In Graduate Students, Catherine G. P. Berdanier

Open Access Dissertations

Although engineering graduate programs rarely require academic writing courses, the indicators of merit in academic engineering, such as journal publications, successful grants, and doctoral milestones (e.g. theses, dissertations) are based in effective written argumentation and disciplinary discourse. Further, graduate student attrition averages 57% across all disciplines, with some studies classifying up to 50% of these students as “ABD” (All But Dissertation.) In engineering disciplines specifically, graduate attrition rates across the U.S. average 36% (both Master’s and PhD students), according to the Council of Graduate Schools. The lack of socialization is generally noted as a main reason for graduate attrition, one …

Enhancing Travel Experience With The Combination Of Information Visualization, Situation Awareness, And Distributed Cognition, Weiran Lei

Open Access Theses

With the new forms of travel introduced by new technologies of transportation and communication, a satisfied travel experience could be affected by various factors before and during a trip. Especially for road trips, traveling by car provides freedom on time control while leading to more possibilities of rescheduling initial plans made under time constraints. When overwhelmed with the need for changed travel context to avoid unexpected events that will require a serious change of initial plans, travelers need to find and access helpful contextual information quickly. This is a context-related decision making process that requires amplifying human situation awareness and …

A Descriptive Analysis Of The Appropriate Use Of Cognitive Bias Terminology In Forensic Science Literature, Courtney A. Winters, Evelyn M. Buday, Trevor I. Stamper

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cognitive bias occurs without a person’s awareness and can affect decision-making abilities. In forensic science, bias can be especially detrimental to making accurate decisions about the evidence in a criminal investigation. There are many academic studies in identifying, describing, and suggesting ways to mitigate cognitive biases in forensic science. Many authors will give a known cognitive science concept a new name or create their own bias. This is a problem in the literature because nobody knows for sure how many published studies are referring to or testing the same phenomena since authors are using different definitions or terminology to describe …
