Distress Tolerance: Prospective Associations With Cognitive-Behavioral Therapy Outcomes In Adults With Posttraumatic Stress And Substance Use Disorders, Anka A Vujanovic, Heather E Webber, Shelby J Mcgrew, Charles E Green, Scott D Lane, Joy M Schmitz

Faculty, Staff and Student Publications

Distress tolerance (DT; perceived or actual ability to tolerate aversive physical or emotional states) is related to both posttraumatic stress disorder (PTSD) symptoms and substance use disorders (SUD). This investigation evaluates self-report and behavioral measures of DT as potential predictors of PTSD and SUD cognitive-behavioral therapy outcomes. Participants included 41 treatment-seeking adults (53.7% women; 73.2% African American; Mage= 44.90, SD = 9.68) who met at least four symptoms of DSM-5 PTSD and DSM-IV substance dependence, assessed via structured interviews. At baseline (pre-treatment), participants completed the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath Holding task, and Paced Auditory …

Misinformation And Disinformation: Detecting Fakes With The Eye And Ai, Victoria Rubin

Data and Test Instruments

How do we detect, deter, and prevent the spread of mis- and disinformationwith the human eye and AI? How does theory inform the practice, and how do theevidence-based research and best practices in lie-catching and truth-seekingprofessions—inform AI? The book looks into well-established human practicessuch as the routines and processes used in detective work, journalism, and scientificinquiry, and how they contribute toward innovative AI solutions. The book explainsthe principles, inner workings, and recent evolution of five types of state-of-the-artAI technologies suitable for curtailing the spread of mis- and disinformation:automated deception detectors, clickbait detectors, satirical fake detectors, rumordebunkers, and computational fact-checking tools.

The Effects Of Floral Attributes And Conspecifics On Bumble Bee Forager Memory, Lucas Lauter, Tiffany Dinh

Undergraduate Research Symposium

What do bees remember about flowers? These memories are important for both bees and flowers. The bees have better foraging success and gain more nectar and pollen from flowers when they remember the most rewarding flower types. More memorable flowers will be visited more frequently, resulting in more successful pollination for the plant. At the same time, bees can also learn about flowers from other bees and may remember this information differently. We are training and testing three floral cues and a single social cue to see how the different types of cues affect their learning and memory of rewarding …

Legislative Language For Success, Sanjana Gundala

Master's Theses

Legislative committee meetings are an integral part of the lawmaking process for local and state bills. The testimony presented during these meetings is a large factor in the outcome of the proposed bill. This research uses Natural Language Processing and Machine Learning techniques to analyze testimonies from California Legislative committee meetings from 2015-2016 in order to identify what aspects of a testimony makes it successful. A testimony is considered successful if the alignment of the testimony matches the bill outcome (alignment is "For" and the bill passes or alignment is "Against" and the bill fails). The process of finding what …

Neurocardiovascular Instability (Ncvi) Risk As A Predictor Of Cognitive Function In The Long Life Family Study, Rebecca Abraham

Dissertations, Theses, and Capstone Projects

In aging populations, the abnormal neural control of the cardiovascular system has been examined within the construct of neurocardiovascular instability (NCVI). The main research aim addressed whether baseline features of NCVI could predict cognitive function (i.e., decline) at follow-up within long-lived families. Across 941 subjects, baseline NCVI risk was indexed by two features: (1) self-reported syncopal or fall events and (2) average seated BP. The Low NCVI risk group included those who were normotensive (e.g., within normal BP range) and reported no NCVI features (n=379). The Moderate NCVI risk group included those who elicited pre-hypertensive (elevated BP) or hypertensive (high …

Pupil Responses To Emotional Images And Relations With Alexithymic And Autistic Traits, Margaret Grinshtein

Dissertations, Theses, and Capstone Projects

Comprehending emotional states in others and oneself is a complex cognitive process. Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication and interaction difficulties. Autistic individuals often show socio-emotional difficulties specifically in emotion recognition and understanding. However, it has been posited that these emotion processing difficulties may be due to alexithymia, a distinct co-occurring phenomenon typified by difficulty in identifying and describing feelings. Autism, alexithymia, and emotion understanding have been studied through behavioral, neural, and psychophysiological methods, and the current study examines how these characteristics are related in a non-autistic sample. Pupil diameter was measured in response …

Possibility Is Not A Luxury: The Role Of Identity In Representations Of Possibility, Hannah M. Lebaron

Dartmouth College Undergraduate Theses

In what ways are our expectations of others and their behaviors limited by the ways they are identified? Broadly, this project asks how identity traits are considered across judgments about which social roles people can assume. This work is an interdisciplinary project that exists within the fields of both Cognitive Science and Women’s, Gender, and Sexuality Studies. As such, the first chapter explores the central issues of identity conception from the perspective of feminist theory, including a discussion of category destabilization, intersectionality, and knowledge production in the context of feminist science studies. 4 empirical studies were launched with methods informed …

Cognitive Task Enhancement Through Alpha Neurofeedback, Hannah L. Meyer, Douglas Peterson

Honors Thesis

Neurofeedback training has been a recent field of study in neuroscience, as a potential way to increase focus, and possibly boost cognitive performance. Most studies utilize a course of neurofeedback training sessions to find positive results in decreasing ADHD symptoms, depression symptoms, as well as further cognitive changes. In this study, we aim to determine the efficacy of a single session of neurofeedback training in increasing cognitive performance. To do so, we randomly separated 42 volunteers into either a control or experimental group. The experimental group participated in an n-back task both before and after an alpha neurofeedback training session, …

Examining The Cross-Cultural Competence Of United States Christian Missionaries Engaged In Developing Indigenous Leaders: A Mixed Methods Study, Craig W. Goodman

Dissertations

For the past two millennia, missionaries have crossed from one culture to another to bring the Christian message to all cultures of the world. Questions about the effectiveness of these mission efforts have been asked and researched by many; however, one key question remains unanswered: what personal attributes help a person to be more competent at crossing cultures as they interact with people from other cultures? Although cross-cultural competence has been studied in a variety of fields over the past 50 years, the models and assessments used have never been applied to Christian missionaries.

To address this deficiency, this parallel …

The Significance Of Sonic Branding To Strategically Stimulate Consumer Behavior: Content Analysis Of Four Interviews From Jeanna Isham’S “Sound In Marketing” Podcast, Ina Beilina

Student Theses and Dissertations

Purpose:
Sonic branding is not just about composing jingles like McDonald’s “I’m Lovin’ It.” Sonic branding is an industry that strategically designs a cohesive auditory component of a brand’s corporate identity. This paper examines the psychological impact of music and sound on consumer behavior reviewing studies from the past 40 years and investigates the significance of stimulating auditory perception by infusing sound in consumer experience in the modern 2020s.

Design/methodology/approach:
Qualitative content analysis of audio media was used to test two hypotheses. Four archival oral interview recordings from Jeanna Isham’s podcast “Sound in Marketing” featuring the sonic branding experts …

Visual Expertise In An Anatomically-Inspired Model Of The Visual System, Garrison W. Cottrell, Martha Gahl, Shubham Kulkarni

MODVIS Workshop

We report on preliminary results of an anatomically-inspired deep learning model of the visual system and its role in explaining the face inversion effect. Contrary to the generally accepted wisdom, our hypothesis is that the face inversion effect can be accounted for by the representation in V1 combined with the reliance on the configuration of features due to face expertise. We take two features of the primate visual system into account: 1) The foveated retina; and 2) The log-polar mapping from retina to V1. We simulate acquisition of faces, etc., by gradually increasing the number of identities the network learns. …

Individual Differences In Structure Learning, Philip Newlin

Theses and Dissertations

Humans have a tendency to impute structure spontaneously even in simple learning tasks, however the way they approach structure learning can vary drastically. The present study sought to determine why individuals learn structure differently. One hypothesized explanation for differences in structure learning is individual differences in cognitive control. Cognitive control allows individuals to maintain representations of a task and may interact with reinforcement learning systems. It was expected that individual differences in propensity to apply cognitive control, which shares component processes with hierarchical reinforcement learning, may explain how individuals learn structure differently in a simple structure learning task. Results showed …

The Role Of Knowledge Representations In Rule Transfer On A Novel Problem-Solving Task, Megan J. Raden

Theses and Dissertations

Although the independent roles of working memory capacity (WMC) and knowledge in problem solving have been thoroughly researched, there is significantly less work that has explored how WMC and knowledge interact during problem solving. The present study investigated how the quality of knowledge representations contribute to rule transfer in a problem-solving context and how WMC might contribute to the subsequent failure or success in transferring the relevant information. Participants were trained on individual figural analogies rules and then asked to rate how similar they thought the rules were to determine how stimulispecific or abstract their rule representations were. Their rule …

Pattern Differentiation And Tuning Shift In Human Sensory Cortex Underlie Long-Term Threat Memory, Yuqi You, Lucas R Novak, Kevin J Clancy, Wen Li

Faculty, Staff and Student Publications

The amygdala-prefrontal-cortex circuit has long occupied the center of the threat system 1, but new evidence has rapidly amassed to implicate threat processing outside this canonical circuit 2-4. Through non-human research, the sensory cortex has emerged as a critical substrate for long-term threat memory 5-9, underpinned by sensory cortical pattern separation/completion 10,11 and tuning shift 12,13. In humans, research has begun to associate the human sensory cortex with long-term threat memory 14,15, but the lack of mechanistic insights obscures a direct linkage. Towards that end, …

Increasing Perceived Realism Of Objects In A Mixed Reality Environment Using 'Diminished Virtual Reality', Logan Scott Parker

Honors Theses

With the recent explosion of popularity of virtual and mixed reality, an important question has arisen: “Is there a way to create a better blend of real and virtual worlds in a mixed reality experience?” This research attempts to determine whether a visual filter can be created and applied to virtual objects to better convince the brain into interpreting a composite of virtual and real views as one seamless view. The method devised in this thesis is being called 'Diminished Virtual Reality'. The results found in this study show that when presented with a scene composed of a combination of …

Probing Nlp Conceptual Relatedness Judgments Through The Word-Based Board Game Codenames, Tracey Mills

Dartmouth College Undergraduate Theses

In this paper I evaluate the ability of different Natural Language Processing (NLP)
techniques to make human-like word relatedness judgements in a variant of the word-based board game Codenames. I analyze a variety of statistical and knowledge based approaches, combinations of these, and techniques for incorporating the wider game context into relatedness judgements. While no approach explored here reaches human performance, simple word embedding based approaches incorporate a surprising amount of the useful information captured by other techniques. I attempt to characterize the limitations of these approaches in relation to human game play, although differences are largely not systematic. Finally, …

Nature-Based Education For Elementary Students With Attention Deficit-Hyperactivity Disorder, Kayleigh Morrison

Capstone Projects and Master's Theses

There are several advantages to including a nature-based curriculum and outdoor learning into state standards, and the consequences of students who do not have access to outside learning and activities can be severe. The term “Attention Restoration Theory” (ART) was coined by psychology professors Rachel and Stephen Kaplan in 1989 and claims that exposure to nature can improve mental fatigue and concentration. This senior capstone examines Kaplan’s Attention Restoration Theory and academic studies rooted in its philosophy as it applies to nature-based curriculum and outdoor learning. There are certain advantages for students who are exposed to a nature-based curriculum and …
