The Plausibility Transition Model For Sensemaking, Gary Klein, Mohammadreza Jalaeian, Robert R. Hoffman, Shane T. Mueller
The Plausibility Transition Model For Sensemaking, Gary Klein, Mohammadreza Jalaeian, Robert R. Hoffman, Shane T. Mueller
Michigan Tech Publications, Part 1
When people make plausibility judgments about an assertion, an event, or a piece of evidence, they are gauging whether it makes sense that the event could transpire as it did. Therefore, we can treat plausibility judgments as a part of sensemaking. In this paper, we review the research literature, presenting the different ways that plausibility has been defined and measured. Then we describe the naturalistic research that allowed us to model how plausibility judgments are engaged during the sensemaking process. The model is based on an analysis of 23 cases in which people tried to make sense of complex situations. …

Cognitive Feedback Theories And Artificial Intelligence: A Case For A Grammarly Of Ui/Ux Design, Jordan Buchanan Paff
Cognitive Feedback Theories And Artificial Intelligence: A Case For A Grammarly Of Ui/Ux Design, Jordan Buchanan Paff
Dartmouth College Undergraduate Theses
This thesis is concerned with utilizing artificial intelligence and machine learning (AI/ML) techniques and cognitive theories of feedback to enhance learning outcomes in the field of user interface and user experience (UI/UX) design. The capabilities of AI/ML have expanded immensely over the past several years, and it is now being effectively used in software programs like Grammarly, a tool that provides intelligent feedback on writing skills including grammar, tone, and clarity. Grammarly has been uniquely successful as a feedback tool because it relies on lessons from cognitive science regarding student feedback and learning outcomes. Currently, there is no comparable software …

Security-Enhanced Serial Communications, John White, Alexander Beall, Joseph Maurio, Dane Fichter, Dr. Matthew Davis, Dr. Zachary Birnbaum
Military Cyber Affairs
Industrial Control Systems (ICS) are widely used by critical infrastructure and are ubiquitous in numerous industries including telecommunications, petrochemical, and manufacturing. ICS are at a high risk of cyber attack given their internet accessibility, inherent lack of security, deployment timelines, and criticality. A unique challenge in ICS security is the prevalence of serial communication buses and other non-TCP/IP communications protocols. The communication protocols used within serial buses often lack authentication and integrity protections, leaving them vulnerable to spoofing and replay attacks. The bandwidth constraints and prevalence of legacy hardware in these systems prevent the use of modern message authentication and …

MODVIS Workshop
Last year, I reported on preliminary results of an anatomically-inspired deep learning model of the visual system and its role in explaining the face inversion effect. This year, I will report on new results and some variations on network architectures that we have explored, mainly as a way to generate discussion and get feedback. This is by no means a polished, final presentation!
We look forward to the group’s suggestions for these projects.
How Object Segmentation And Perceptual Grouping Emerge In Noisy Variational Autoencoders, Ben Lonnqvist, Zhengqing Wu, Michael H. Herzog
How Object Segmentation And Perceptual Grouping Emerge In Noisy Variational Autoencoders, Ben Lonnqvist, Zhengqing Wu, Michael H. Herzog
MODVIS Workshop
Many animals and humans can recognize and segment objects from their backgrounds. Whether object segmentation is necessary for object recognition has long been a topic of debate. Deep neural networks (DNNs) excel at object recognition, but not at segmentation tasks - this has led to the belief that object recognition and segmentation are separate mechanisms in visual processing. Here, however, we show evidence that in variational autoencoders (VAEs), segmentation and faithful representation of data can be interlinked. VAEs are encoder-decoder models that learn to represent independent generative factors of the data as a distribution in a very small bottleneck layer; …
Constraining The Binding Problem Using Maps, Zhixian Han, Anne Sereno
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.
The Effects Of Color On Flavor, Tiffany S. Yoo
The Effects Of Color On Flavor, Tiffany S. Yoo
Honors Capstones
Color and its relation to flavor, is a complex cognitive phenomenon that researchers today are still trying to decipher. The present literature review is an examination of the history of color, process of color perception, the effects of additional factors such as saturation, the exploration of senses that may potentially contribute to perception itself, and the different modern theories suggested. The purpose of this project was to review, revise, and narrow down which theories can be deemed as accurate in terms of the amount of support addressed by modern literature. While a clear-cut answer was not concluded, three potential theories …
Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer
Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer
Art Theses and Dissertations
To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Evaluating Machine-Generated Explanations: A “Scorecard” Method For Xai Measurement Science, Robert R. Hoffman, Mohammadreza Jalaeian, Connor Tate, Gary Klein, Shane T. Mueller
Michigan Tech Publications, Part 1
Introduction: Many Explainable AI (XAI) systems provide explanations that are just clues or hints about the computational models-Such things as feature lists, decision trees, or saliency images. However, a user might want answers to deeper questions such as How does it work?, Why did it do that instead of something else? What things can it get wrong? How might XAI system developers evaluate existing XAI systems with regard to the depth of support they provide for the user's sensemaking? How might XAI system developers shape new XAI systems so as to support the user's sensemaking? What might be a useful …
The Effect Of Word Predictability On Proofreading Accuracy And Reading Time, Sam Prasad
The Effect Of Word Predictability On Proofreading Accuracy And Reading Time, Sam Prasad
Theses and Dissertations
Proofreading, or reading with the purpose of finding and correcting errors, has been used in psycholinguistic research to study the relationship between bottom-up and top-down cognitive processes. The current study examined the effects of word predictability on reading time using a word-by-word self-paced reading (SPR) task. A sample of 102 native English speakers read sentences containing letter transposition errors in predictable and unpredictable contexts. Half of the sentences were followed by a question asking if there was an error in the sentence they had just read. Participants’ accuracy in detecting the errors and the time they spent reading the error-bearing …

Inner Portraits, Bethany Salisbury
Inner Portraits, Bethany Salisbury
Graduate Theses
This paper investigates the many interconnected layers of women’s mental health through portraiture and how animal and plant symbolism can represent the way women's hormones and bodily health affect their mental health. I reveal how the artwork created presents these connections and inner mental health narratives to the viewer, creating a space of empathy, destigmatization, and self-reflection. This body of portraiture art connects five women through a series of both two-and three-dimensional portraits based on interviews using my own adaptation of Sara Lawrence-Lightfoots’ (1983) portrait methodology.
Women and non-binary individuals have always dealt with difficult interactions of bodily and mental …
Genetic Implications Of Language Acquisition, Marissa Renee Ciccarini
Genetic Implications Of Language Acquisition, Marissa Renee Ciccarini
Honors Scholar Theses
The argument about whether language acquisition is "nature" or "nurture" has been long debated. Linguists have concluded that it requires the two, but how much does language acquisition rely on nature? Children show the capacity to learn languages quickly and without much effort. While research suggests that infants absorb many visual and verbal cues in their environment, biological structures are the underlying component of how this knowledge is gathered and organized. The genetics that code for specific neurophysiological pathways affect how people interact with their environment and where information is stored, forming the basis for these biological structures. Genetic research …

Does Using Clicker Questions Before Instruction Improve Students' Conceptual Understanding., Edward "Walker" Goshorn
College of Arts & Sciences Senior Theses
Active learning can be incorporated into STEM classrooms in multiple ways. With exploratory learning, students explore a novel activity before learning the concepts or procedures. With personal response devices (e.g., clickers), students respond to real-time questions posed during lecture. The current studies examined whether, and how, clicker questions can be used as exploratory learning, to improve students’ conceptual understanding and engagement over traditional instruction. Biology professors integrated clicker questions into a lecture, and either closed the clicker poll prior to (Restricted Clicker Experiment, N = 164) or after (Extended Clicker Experiment, N = 188) giving feedback to the class. Undergraduate …
Creative Problem Solving Using Visual Thinking, Jacob L. Ravnborg
Creative Problem Solving Using Visual Thinking, Jacob L. Ravnborg
Creativity and Change Leadership Graduate Student Master's Projects
Creative Problem Solving Using Visual Thinking
This project explores the concept of visual and semantic thinking and how they can be incorporated into Creative Problem Solving sessions. Visual thinking is the ability to conjure mental images as part of the thinking process. This type of thinking is hard-wired into the human brain and can be seen in individual behavior and language. Meanwhile, semantic thinking is using language and grammar to convey meaning. It is a sequential process that depends on cultural and social references. The project argues that both types of thinking are essential and recommends specific guidelines for including …

Following a stressful life event, there is considerable variation in how individuals respond and adapt. Multiple models of risk and resilience show that adverse childhood experiences may be associated with an individual's response to stress later in life. While there is considerable support that early adversity can sensitize the stress response system and lead to adverse outcomes later in life, there is mounting evidence that in adolescence and young adulthood, certain biological predispositions to stress may be associated with resilience in the context of subsequent stressors. In this study, we evaluated how individual differences in vagally mediated heart rate variability …

A Comparison Of The Expressive Language Characteristics In Schizophrenia And Wernicke’S Aphasia, Taylor Thomas
Electronic Theses and Dissertations
Mental illness and language disorders are rarely linked together as a way of making a comparison. In this study, a comprehensive scoping review was initiated to discuss the differential diagnostic characteristics of expressive language in Schizophrenia and Wernicke’s Aphasia (WA). This study will examine the domains of language where there are overlaps between the characteristics of expressive language. Semantics, pragmatics, and discourse will be further examined while comparing what aspects of expressive language are key in each domain. Schizophrenia being classified as a mental illness and WA being classified as an acquired language disorder, there are fundamental properties of language …
Mental Confidence In Alzheimer's Disease, Harrison Adams
Mental Confidence In Alzheimer's Disease, Harrison Adams
Electronic Theses and Dissertations
A simple symptom like forgetfulness can lead to a gradual, subtle decline in the individual’s sense of identity. In dementia, self-efficacy is the foundation that allow individual to prolong their capacity of independence and identity. Alzheimer’s disease (AD) is the most prominent form of dementia with tens of millions in the world currently living with Alzheimer’s disease. AD is most often associated with impaired memory, confusion, language impairment, and unpredictable, agitated, aggressive, and paranoid behavior. While there are many studies examining the quality of life in individuals with AD, there are fewer investigating the psychological effects of AD on the …

Impacts Of Poverty On Language Development How Low Socio-Economic Status Students Are At An Academic Disadvantage, Farbod Samari
Electronic Theses, Projects, and Dissertations
ABSTRACT
Socioeconomic status impacts a variety of mental health outcomes, including language development. Delays in language development have consistently been linked to poverty. Decreases in vocabulary and phonological awareness are among developmental delays in school-aged children living in poverty. This research aims to contribute to the field of human services by examining the negative impacts of poverty on language development from a social worker’s perspective. As social workers thrive to serve disadvantaged populations, this research brings awareness to how language development deficiencies occur in school-aged children living in poverty.
To fulfill the purpose of this study, a quantitative, descriptive/explanatory design …
The Dynamics Of Emotion-Related Impulsivity: An Analysis Of Emotional Control And Daily Emotion-Driven Urges And Actions Via Ecological Momentary Assessment, Jeremy B. Clift
Graduate Theses and Dissertations
Emotion-related impulsivity, or the engagement in impulsive reactions specifically in response to emotions, has been identified as a crucial transdiagnostic factor. Mixed evidence from ecological momentary assessments (EMA) underscores a potential discrepancy between the existing measurements of emotion-related impulsivity at trait and state levels. Unlike previous EMA studies examining emotion-related impulsivity through measures of urgency, the current study tested Carver and colleagues’ (2008) reflexive responding to emotion framework by investigating the relationship between emotional control and emotion-related impulsivity. Participants (N = 197) with varying levels of emotional control completed one week of EMA to investigate two central questions. First, we …

Music & Synesthesia: An Exploration Of Synesthesia And Its Relation To Musical Perception, Raquel S. Johnson
Music & Synesthesia: An Exploration Of Synesthesia And Its Relation To Musical Perception, Raquel S. Johnson
Pacific Undergraduate Research and Creativity Conference (PURCC)
This research investigates synesthesia and its impact on musical perception. Synesthesia is the multimodal sensory phenomenon in which the stimulation of one sensory modality generates the experience of a second, otherwise unrelated sense. Discussed topics include: a description of synesthesia and its neurophysiological and perceptual characteristics, the historical conceptualization and documentation of synesthesia beginning with the ancient Greeks, and present-day scientific inquiry. This research explores three varying types of auditory synesthesia - chromesthesia (sound-to-color synesthesia), auditory-tactile synesthesia, and sound-gustatory/sound-olfactory synesthesia - and their multimodal sensory characteristics in relation to music. Prominent neurophysiological hypotheses regarding the existence of synesthesia are examined, …
Genetic Loci Of Beta-Aminoisobutyric Acid Are Associated With Aging-Related Mild Cognitive Impairment, Einat Granot-Hershkovitz, Brian Spitzer, Yunju Yang, Wassim Tarraf, Bing Yu, Eric Boerwinkle, Myriam Fornage, Thomas H Mosley, Charles Decarli, Bruce S Kristal, Hector M González, Tamar Sofer
Genetic Loci Of Beta-Aminoisobutyric Acid Are Associated With Aging-Related Mild Cognitive Impairment, Einat Granot-Hershkovitz, Brian Spitzer, Yunju Yang, Wassim Tarraf, Bing Yu, Eric Boerwinkle, Myriam Fornage, Thomas H Mosley, Charles Decarli, Bruce S Kristal, Hector M González, Tamar Sofer

We studied the genetic associations of a previously developed Metabolomic Risk Score (MRS) for Mild Cognitive Impairment (MCI) and beta-aminoisobutyric acid metabolite (BAIBA)-the metabolite highlighted by results from a genome-wide association study (GWAS) of the MCI-MRS, and assessed their association with MCI in datasets of diverse race/ethnicities. We first performed a GWAS for the MCI-MRS and BAIBA, in Hispanic/Latino adults (n = 3890) from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). We identified ten independent genome-wide significant (p value <5 × 10-8) variants associated with MCI-MRS or BAIBA. Variants associated with the MCI-MRS are located in the Alanine-Glyoxylate Aminotransferase 2 (AGXT2 gene), which is known to be associated with BAIBA metabolism. Variants associated with BAIBA are located in the AGXT2 gene and in the SLC6A13 gene. Next, we tested the variants' association with MCI in independent datasets of n = 3178 HCHS/SOL older individuals, n = 3775 European Americans, and n = 1032 African Americans from the Atherosclerosis Risk In Communities (ARIC) study. Variants were considered associated with MCI if their p value <0.05 in the meta-analysis of the three datasets and their direction of association was consistent with expectation. Rs16899972 and rs37369 from the AGXT2 region were associated with MCI. Mediation analysis supported the mediation effect of BAIBA between the two genetic variants and MCI (p value = 0.004 for causal mediated effect). In summary, genetic variants in the AGXT2 region are associated with MCI in Hispanic/Latino, African, and European American populations in the USA, and their effect is likely mediated by changes in BAIBA levels.
