Sensing Fear: Fast And Precise Threat Evaluation In Human Sensory Cortex, Wen Li, Andreas Keil

Faculty, Staff and Student Publications

Animal models of threat processing have evolved beyond the amygdala to incorporate a distributed neural network. In human research, evidence has intensified in recent years to challenge the canonical threat circuitry centered on the amygdala, urging revision of threat conceptualization. A strong surge of research into threat processing in the sensory cortex in the past decade has generated particularly useful insights to inform the reconceptualization. Here, synthesizing findings from both animal and human research, we highlight sensitive, specific, and adaptable threat representations in the sensory cortex, arising from experience-based sculpting of sensory coding networks. We thus propose that the human …

Beyond Machine Learning: An Fmri Domain Adaptation Model For Multi-Study Integration, Lauryn Michelle Burleigh

LSU Doctoral Dissertations

Traditional machine learning analyses are challenging with functional magnetic
resonance imaging (fMRI) data, not only because of the amount of data that needs to be
collected, adding a particular challenge for human fMRI research, but also due to the change in
hypothesis being addressed with various analytical techniques. Domain adaptation is a type of
transfer learning, a step beyond machine learning which allows for multiple related, but not
identical, data to contribute to a model, can be beneficial to overcome the limitation of data
needed but may address different hypothesis questions than anticipated given the analysis
computation. This dissertation assesses …

Problems Are A Gift- How To Turn Challenging Behaviors In The Classroom Into Opportunities For Growth And Connection, Lindsey Kealey

National Youth Advocacy & Resilience Conference

Lindsey Kealey discusses practical ways apply a trauma-responsive approach to helping children and adults solve problems in the classroom. When you unwrap problems with students in productive, rather than punitive ways, you will find that problems are not just fires to put out or issues that weight us down. Rather, problems can be a gift to ourselves and the students we teach.

Measures For Explainable Ai: Explanation Goodness, User Satisfaction, Mental Models, Curiosity, Trust, And Human-Ai Performance, Robert R. Hoffman, Shane Mueller, Gary Klein, Jordan Litman

Michigan Tech Publications, Part 1

If a user is presented an AI system that portends to explain how it works, how do we know whether the explanation works and the user has achieved a pragmatic understanding of the AI? This question entails some key concepts of measurement such as explanation goodness and trust. We present methods for enabling developers and researchers to: (1) Assess the a priori goodness of explanations, (2) Assess users' satisfaction with explanations, (3) Reveal user's mental model of an AI system, (4) Assess user's curiosity or need for explanations, (5) Assess whether the user's trust and reliance on the AI are …

David Versus Goliath: The Power Of Weakness In Asymmetric Warfare—Lessons From History, Nicholas K. Petaludis

Dissertations, Theses, and Capstone Projects

Under what conditions do violent nonstate actors (VNA) succeed against states? Why does David sometimes beat Goliath? Since at least the time of Thucydides and the Peloponnesian Wars, the realist narrative in international relations measures power primarily in relative, coercive, and deterrent terms. Strong states should accordingly face fewer constraints and enjoy more options while pursuing their national interests. Unconventional warfare, and its subsets of terrorism and insurgency, should—given these circumstances, end in VNA failure. Sometimes, however, VNAs find success. By comparing the literature on historical and current case studies, I propose that a set of preconditions and two mechanisms …

The Case Of The Disappearing Owner: Do Dogs Show Behavioral Evidence Of Violation Of Expectation?, Rita Kanagat

Theses and Dissertations

The What the Fluff challenge became a series of viral YouTube videos that started in 2018. In the videos, a person stood behind a blanket in a doorway in front of their dog and lifted and lowered the blanket revealing and obscuring themselves, and finally disappearing with a final blanket drop. The dogs’ reactions were varied but were suggestive of a violation of expectation response. We conducted a community science study that employed methodologies consistent with the What the Fluff Challenge paradigm that were conducted in the owners’ homes with their dogs. Each owner was required to run a control …

Hmm, You Seem Confused! Tracking Interlocutor Confusion For Situated Task-Oriented Hri, Na Li, Robert J. Ross

Articles

Our research seeks to develop a long-lasting and high-quality en- gagement between the user and the social robot, which in turn requires a more sophisticated alignment of the user and the system than is currently commonly available. Close monitoring of inter- locutors’ states, and we argue their confusion state in particular, and adjusting dialogue policies based on this state of confusion is needed for successful joint activity. In this paper, we present an ini- tial study of a human-robot conversation scenarios using a Pepper robot to investigate the confusion states of users. A Wizard-of-Oz (WoZ) HRI experiment is illustrated in …

A Novel Digital Digit-Symbol Substitution Test Measuring Processing Speed In Adults At Risk For Alzheimer Disease: Validation Study, Anthony Campitelli, Sally Paulson, Josh L. Gills, Megan D. Jones, Erica N. Madero, Jennifer Myers, Jordan M. Glenn, Michelle Gray

Health, Human Performance and Recreation Faculty Publications and Presentations

Background: Assessing cognitive constructs affected by Alzheimer disease, such as processing speed (PS), is important to screen for potential disease and allow for early detection. Digital PS assessments have been developed to provide widespread, efficient cognitive testing, but all have been validated only based on the correlation between test scores. Best statistical practices dictate that concurrent validity should be assessed for agreement or equivalence rather than using correlation alone.

Objective: This study aimed to assess the concurrent validity of a novel digital PS assessment against a gold-standard measure of PS.

Methods: Adults aged 45-75 years (n=191) participated in this study. …

Gender Bias In Story Recounting, Cecilia Garcia, Zali White, Keeley Trainer, Madison Oliver

[Archive] Belmont University Research Symposium (BURS)

Gendered language permeates sections of our lives in ways that we may not realize. Previous research indicates a relationship between biases and gendered language; however, it has primarily been conducted with children as the participants rather than adults (Seitz, et al., 2020). This study aimed to investigate this and identify the relationship between gendered language and implicit bias. Passages using gendered language can alter the listener's perspective in terms of the gender identification of an otherwise unlabeled protagonist. Therefore, to explore this phenomenon, participants of this study were given an androgynous story with masculine and feminine phrases. Then, a multiplication …

A Machine Learning Approach To Deepfake Detection, Delaney Conrad

All Undergraduate Theses and Capstone Projects

The ability to manipulate videos has been around for decades but a process that once would take time, money, and professionals, can now be created by anyone due to the rapid advancement of deepfake technology. Deepfakes use deep learning artificial intelligence to make fake digital content, typically in the form of swapping a person’s face in a video or image. This technology could easily threaten and manipulate individuals, corporations, and political organizations, so it is essential to find methods for detecting deepfakes. As the technology for creating deepfakes continues to improve, these manipulated videos are becoming increasingly undetectable. It is …

Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder

Undergraduate Honors Theses

The following project involves a systematic review of the scientific literature on neural and biological changes of mothers and fathers in parenthood. Until very recently, little scientific research was devoted to studying how bearing children affects a man or woman’s long-term biology. Over the last twenty years, studies of neuroplastic changes in new mothers show specific neural mechanisms responsible for altering the behaviors of mothers during and after pregnancy. These changes in neuroplasticity alter behavior in such a way that led to mothers requiring less sleep and being more prone to hearing the cries of their children. In addition to …

Stereotype Threat In Older Adults’ Episodic Memory Tests: Susceptibility And Protection, Talia Barrett

Honors Theses

The objective of the present study was to investigate whether prior task success would protect older adults against stereotype threat in an episodic memory test. Previous experiments have established that, whereas stereotype threat negatively impacts older participants’ episodic memory performance, prior task success benefits it. However, up until this point, researchers had yet to combine the two manipulations to test their joint effect on episodic memory. Participants were randomly assigned to read a stereotype threat or neutral passage, after which they were placed in the success or no success group. Participants next received a stereotype condition reminder, and they then …

The Construct Validity Of The Wechsler Abbreviated Scale Of Intelligence, Second Edition (Wasi-Ii) And The Reynolds Intellectual Assessment Scales, Second Edition (Rias-2), Mckenzie K. Sopoci

Masters Theses

The Wechsler Abbreviated Scale of Intelligence, Second Edition (WASI-II; Wechsler, 2011) and the Reynolds Intellectual Assessment Scales, Second Edition (RIAS-2; Reynolds & Kamphaus, 2015) are two intelligence tests created to assess general intelligence, using four subtests reflecting two verbal and two nonverbal (perceptual reasoning) tasks. Both tests overlap to assess individuals between the ages of 6 to 90, and while the WASI-II is specified by the publisher as a screening measure, the RIAS-2 is not. Tests like the WASI-II and RIAS-2 may provide more efficient assessment of general intelligence, which can reduce assessment time and allow professionals to engage in …

Neurobiology Of Ptsd In Adults And Children: The Impact Of Stress-Induced Brain Abnormalities Across The Lifespan, Catherine Clover

Undergraduate Honors Theses

In the scholarly community, there is disagreement about the effects of PTSD or chronic stress on the brain of adults and children. Though PTSD or chronic stress are known to negatively affect neurobiological structures, specifically due to prolonged glucocorticoid excess, volumetric discrepancies between traumatized and control groups are not unanimously confirmed. This review sought to address the common understandings in academia of the effects of PTSD on the brains of adults and children. Literature on this topic indicated that, in adults, the hippocampus, cingulate gyrus, and prefrontal cortex bilaterally appeared to decrease in gray matter volume and the corpus callosum …

Sustaining Breaths For Restorative Rest: A Preliminary Evaluation Of Sleep, Mental Health, And Cognitive Function Following Hypoglossal Nerve Stimulation For Obstructive Sleep Apnea, Elliottnell Perez

Theses and Dissertations

Introduction: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that produces repetitive obstruction or collapse of the upper airway. Positive airway pressure (PAP) therapy is the gold standard treatment for OSA. Hypoglossal nerve stimulation (HNS) is considered an alternative treatment for patients who are unable to tolerate PAP therapy. The purpose of the study was to examine sleep, mental health, and cognitive health outcomes before and after HNS to determine its viability as an alternative treatment.

Methods: The study utilized a single-group, pretest-posttest design. Objective and subjective sleep was measured using actigraphy, sleep diary, and questionnaires. Objective and subjective …

Bypass Language En Route To Meaning At Your Peril, Lindsay N. Harris, Charles A. Perfetti, Elizabeth Hirshorn

CISLL Publications

The learning account of the puzzle of ideography cannot be dismissed as readily as Morin maintains, and is compatible with the standardization account. The reading difficulties of deaf and dyslexic individuals, who cannot easily form connections between written letter strings and spoken words, suggest limits to our ability to bypass speech and reliably access meaning directly from graphic symbols.

Infant-Maternal Behaviors During Non-Maternal Infant Handling Interactions In Captive Long- Tailed Macaques (Macaca Fascicularis), Kristy Abney

All Master's Theses

The main caregiver of an infant Long-tailed macaque (Macaca fascicularis) is their mother. However, mothers often allow infant-handling interactions with other individuals in their group. While there are many hypotheses to explain the infant-handling phenomenon, there are few systematic investigations of how mothers respond to non-mother infant-handling interactions. At Alpha Genesis Inc., I conducted 33 focal follows for each mother-infant dyad (N = 10) over an eight-week period on captive macaques to determine if infant behaviors during infant-handling interactions resulted in mothers interrupting the interaction; if mothers were more likely to interrupt infant-handling interactions when infants showed signs …

The Neuroscience Of Social Comparison And Competition, Avishalom Tor, Stephen M. Garcia

Journal Articles

The study of competition from a social comparison perspective offers valuable insights into the neuroscience of social judgment and decision making under uncertainty. When engaging in social comparison, individuals seek and assess information about similarities or differences between others and themselves, in large part to improve their self-evaluation. By providing information about one’s relative position, abilities, outcomes, and more, social comparisons can inform competitive judgments and decisions. People reasonably turn to social comparisons to reduce uncertainty before, during, and after competition. However, the extent to which they do so and the behavioral consequences of social comparisons often fail to match …

Types Of Questions Teachers Ask To Engage Students In Making Sense Of A Student Contribution, Nishat B. Alam

Dissertations, Master's Theses and Master's Reports

In the student-centered classroom, a teacher’s interpretation and response to student mathematical contributions plays an important role to shape and direct students’ opportunities for sense-making. This research used a scenario-based survey questionnaire to examine what types of questions middle and high school mathematics teachers indicate they would ask to engage students in making sense of a high-leverage student mathematical contribution and their reasoning about why particular questions are or are not productive. From the results, it could be concluded that teachers asked more productive questions after seeing a set of possible questions. Their beliefs about the productivity of the questions …

Using Historical Thinking Strategies For Improving Elementary Students’ Content Knowledge And Attitudes Towards Social Studies, Lydia Burnett, Joshua Cuevas Dr.

Georgia Educational Researcher

Instructional time spent on elementary social studies is often marginalized due to the emphasis placed on other content areas. Therefore, social studies teachers must employ meaningful instructional strategies that will engage students while promoting content acquisition. This quasi-experimental study responds to this challenge by guiding a sample of 44 fifth grade students to use the historical thinking skills of sourcing, contextualizing, and corroborating that encourage engagement with a variety of primary sources through the lens of Jerome Bruner’s learning theories. The control group used traditional instructional methods including close-note taking, vocabulary review, and independent reading from social studies texts. Both …

Tools For Collective Thought: Augmenting Collaborative Sensemaking, Jacob Zimmerman

Pomona Senior Theses

As some pioneers of personal computing argue, we have yet to reach the potential that computing offers to enhance our cognition. Some modern scholars of tools for thought give a prerogative to develop transformative tools for thought (Matuschak & Nielsen, 2019), recognizing that the tools we may use enable new thought patterns and thus new cognitive abilities. As cognition is mediated both by our tools and by the minds of others, I evaluate the current state of literature on tools built to support collaborative sensemaking, a domain of collective cognition characterized by various interdependent cognitive processes. To apply and test …

Effects Of Social Context On Salivary Cortisol And Attention In Tufted Capuchins (Cebus [Sapajus] Apella), Andrew Desana

Master’s Theses

Social context alters cognitive performance, but the mechanisms for this remain unclear. One possibility is that stressors associated with social contexts mediate changes in cognitive performance by influencing attention. We conducted two experiments to investigate how social context affects performance on an attention task in capuchin monkeys (Cebus [Sapajus] apella). We additionally validated and measured physiological stress through salivary cortisol. In experiment one, capuchins were exposed to three conditions where they were either isolated or paired with an affiliative or agonistic social partner separated by a barrier. In experiment two, subjects received affiliative and agonistic conditions without barriers to allow …

Explicit Rule Learning: A Cognitive Tutorial Method To Train Users Of Artificial Intelligence/Machine Learning Systems, Anne Linja

Dissertations, Master's Theses and Master's Reports

Today’s intelligent software systems, such as Artificial Intelligence/Machine Learning systems, are sophisticated, complicated, sometimes complex systems. In order to effectively interact with these systems, novice users need to have a certain level of understanding. An awareness of a system’s underlying principles, rationale, logic, and goals can enhance the synergistic human-machine interaction. It also benefits the user to know when they can trust the systems’ output, and to discern boundary conditions that might change the output. The purpose of this research is to empirically test the viability of a Cognitive Tutorial approach, called Explicit Rule Learning. Several approaches have been used …

The Influence Of Early Childhood Parental Feeding Behaviors On Self-Regulation & Food Decision-Making In Young Adults, Natasha Singareddy

CMC Senior Theses

This study used data from a diverse set of undergraduates from the Claremont Colleges to examine the relationship between cognitive control (impulsivity and response inhibition) and self-regulatory ability as an indicator of sustained early childhood parental feeding behaviors in adulthood. In addition, the current study explored if early childhood parental feeding behaviors predicted food decision-making in adulthood as a result of perceived taste and nutritional value of food items. It was hypothesized that heightened impulsivity and impaired response inhibition as measures of cognitive control would correlate to poorer self-regulation, in turn reflecting a particular mode of early childhood parental feeding …

Identifying The Main Causes For Support Of Crime Control Theater Forms, And Understanding How To Correct The Public’S Perception, Erisjames M. Elliott

CMC Senior Theses

Much research has been completed on the forms of crime control theater (CCT), and the impact that the existence of CCT laws have on society. Research on CCT laws has shown that they are definitively unsuccessful in providing the safety they were created to provide. This thesis will utilize completed research to explain the main psychological phenomena holding people back from decreasing their support for CCT laws. It will also describe proven methods of correcting misinformation in order to change the perceptions of people who support crime control theater laws, and provide suggestions for how research should be continued.
