Individual Concepts And Personal Identity Judgement, Molly M. Ye

Theses and Dissertations

Previous research into personal identity judgments has yielded conflicting outcomes. This paper introduces an alternative argument, proposing that the concept PERSON and HUMAN BEING provide different ways of thinking about the identity of people. Two experiments in this study provide evidence for this claim.

Reporting On Un Security Council: Decoding Media Bias, Alessandra Loiero

Dissertations and Theses

This thesis explores Western media's representation of the United Nations (UN), focusing on the Security Council's role in global conflict resolution. It examines how UN-accredited correspondents perceive the effectiveness of the Security Council, particularly when the body faces deadlock. The study employs text analysis techniques to identify biases and perceptions in media coverage, using The New York Times' reporting on the Ukraine conflict as a case study. It illuminates framing effects in journalistic narratives, revealing how journalists subtly interject their views when reporting, often revealing unrealistic expectations and shedding light on the limitations of the UN's mandate or its inability …

Exploring Spatial Operations Of Distractor Suppression In The Sense Of Touch, Nicole A. Serino

Dissertations and Theses

The ability to select sensory information in our environment is key to facilitating goal-directed actions. Sensory selection mechanisms are prevalent in all sensory modalities, and can be implemented by enhancing information at the relevant location and/or suppressing neural information outside the focus of attention (a mechanism known as distractor suppression). Although we have a decent understanding of how the brain enhances information within the focus of attention, less is known about the mechanisms that mediate suppression of distractors, especially in sensory modalities outside vision. In this study, we conducted a series of behavioral experiments to investigate the spatial flexibility of …

Balanced Blended Space: Proposing A Universal Theoretical Framework For Combinative Reality, David Smith, Frederick Bianchi

Publications and Research

In today's fragmented societies, a unified framework for communication and collaboration across different realities is crucial. We introduce Balanced Blended Space (BBS) as a framework for describing combinative reality, encompassing virtual, physical, and conceptual realms, all intrinsically connected. Interactions within these environments shape our perceptual space. This paper outlines key axiomatic assumptions, criteria for a universal framework, and fundamental terminology. We identify deep symmetries enabling the BBS framework, including Cognitive and Computational Symmetry, Physical and Virtual Symmetry, Mediation Pathway Symmetry, Space-Time Symmetry, and Sensory Symmetry. We propose tests to determine its viability, emphasizing virtual intelligence as a collaborative partner. We …

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

The Neural Correlates Of Bodily Self-Consciousness In Virtual Worlds, Evan A. Owens

Dissertations, Theses, and Capstone Projects

Bodily Self-Consciousness (BSC) is the cumulative integration of multiple sensory modalities that contribute to our sense of self. Sensory modalities, which include proprioception, vestibulation, vision, and touch are updated dynamically to map the specific, local representation of ourselves in space. BSC is closely associated with bottom-up and top-down aspects of consciousness. Recently, virtual- and augmented-reality technology have been used to explore perceptions of BSC. These recent achievements are partly attributed to advances in modern technology, and partly due to the rise of virtual and augmented reality markets. Virtual reality head-mounted displays can alter aspects of perception and consciousness unlike ever …

Attenuated Typicality Effect In Category-Based Inferences: Implications For Autism Spectrum Disorder, Janani Rajagopalan

Dissertations, Theses, and Capstone Projects

Individuals diagnosed with Autism Spectrum Disorder (ASD) often encounter challenges in assimilating atypical exemplars into their categorical prototypes, a cognitive hurdle that can impact their interpretative and integrative capacities. Addressing this problem, the present research sought to develop a robust methodological approach to reduce the effect of this disparity. We examined the elements embedded within the category's internal structure, with the intention of experimentally attenuating the pronounced typicality effect, which is often exaggerated in ASD.

Across four experiments, the thesis investigated the cognitive and neural underpinnings that shape the access to the typicality gradient intrinsic to a category's structure. The …

The Politics Of Expertise And The Articulation Of Authority In Democracy: Cognitive Style And Intelligibility In The Education Of Problem-Solving And Professional Decision-Making In The Domain Of Law, Michael W. Raphael

Dissertations, Theses, and Capstone Projects

Computational complexity refers to the representational aspect of problem-solving. This representational aspect is commonly understood to describe the regularities that organize the definition of the problem-situation, the qualities that designate its difficulty, either in terms of the process of arriving at a definition of the problem or in the process of arriving at a solution. It is for this reason, that it is commonly said that “representational design precedes computational efficacy.” The point of this maxim is to serve as a reminder that an efficient use of resources begins with the design of near decomposability, the specification of the properties …

Association Strength Between Concepts As The Origin Of The "Foreign Language Effect", Emilia Ezrina

Dissertations, Theses, and Capstone Projects

Bilinguals sometimes make decisions in verbal tasks differently in their first (L1) and second (L2) language. This phenomenon is known as the foreign language effect (FLE), and it suggests strong connections between language and cognition. On the one hand, it is possible that L2 “blunts” emotional language. However, the FLE can be observed in non-emotional tasks. Therefore, it is possible that L2 requires more deliberate processing due to increased cognitive load, leading to more rational decisions. The support for each explanation is mixed.

In this thesis we propose looking for a single explanation for all instances of the FLE. After …

Extinction Of Threat Memory Via Reconsolidation Interference: A Behavioral Intervention Meta-Analysis, Chris M. Andrae

Dissertations, Theses, and Capstone Projects

Threat memories are created when an aversive stimulus is paired with other stimuli such that the associated stimuli elicit the same reaction as the unpleasant one. Anxiety disorders are usually treated with exposure to aversive stimuli. Emotional memories can be altered through a process called reconsolidation interference. Consolidated memories are dynamic: reminders of previous experiences prompt the reactivation of a previously-encoded memory; destabilization of the memory opens it to update. While a memory is updating, it is labile. If extinction training occurs during reconsolidation (i.e., shortly after reactivation), the conditioned stimulus will no longer elicit the conditioned response. Thus, previously-encoded …

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 …

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 …

Theorizing, Bounded Rationality, And Expertise: Cognitive Sociology And The Quasi-Realism Of Problem-Solving As A Course Of Activity, Michael W. Raphael

Publications and Research

The question facing sociology is whether it is a field or a discipline. If it is a field, then there is no need for theorizing. However, if sociology is a discipline, then problem-solving cannot be disentangled from theorizing without a loss of intelligibility – the inability to explain the social as the concept of the discipline. Through the quasi-realism of problem-solving as a course of activity, this chapter presents cognitive sociology as a paradigm appropriate to the concept of the social understood as an ongoing course of activity. In doing so, it is shown how bounded rationality and expertise play …

Computational Thinking And Coding For Young Children: A Hybrid Approach To Link Unplugged And Plugged Activities, Daisuke Akiba

Publications and Research

In our increasingly technology-dependent society, the importance of promoting digital literacy (e.g., computational thinking, coding, and programming) has become a critical focus in the field of childhood education. While young children these days are routinely and extensively exposed to digital devices and tools, the efficacy of the methods for fostering digital skills in the early childhood classroom has not always been closely considered. This is particularly true in settings where early childhood educators are not digital experts. Currently, most of the efforts in standard early childhood settings, taught by teachers who are not digital experts, appear to revolve around “unplugged” …

Artificial Intelligence And The Situational Rationality Of Diagnosis: Human Problem-Solving And The Artifacts Of Health And Medicine, Michael W. Raphael

Publications and Research

What is the problem-solving capacity of artificial intelligence (AI) for health and medicine? This paper draws out the cognitive sociological context of diagnostic problem-solving for medical sociology regarding the limits of automation for decision-based medical tasks. Specifically, it presents a practical way of evaluating the artificiality of symptoms and signs in medical encounters, with an emphasis on the visualization of the problem-solving process in doctor-patient relationships. In doing so, the paper details the logical differences underlying diagnostic task performance between man and machine problem-solving: its principle of rationality, the priorities of its means of adaptation to abstraction, and the effects …

Pervasive Nonarbitrariness: Meaning From Form In Natural Language, David J. Neely

Dissertations, Theses, and Capstone Projects

It is generally assumed that the expressions of a natural language are largely arbitrary. That is, any expressions that display a nonarbitrary connection between what their utterances sound like and what they mean are small in number and of no real theoretical importance.

This thesis challenges such a position. I argue that nonarbitrariness is a pervasive feature of natural language and that understanding the sound/meaning connections that exist in language is necessary if to appreciate how languages work.

I begin, in Chapter 1, by showing that many theorists are committed to the idea that nonarbitrary sound/meaning connections are of little …

Retrieval Practice Promotes Learning Of Turkish As A Foreign Language: A Computer-Assisted Language Learning Study, Maya C. Rose

Dissertations, Theses, and Capstone Projects

Adults generally find it difficult to learn a new language, yet exhibit remarkable individual differences in outcomes. Variation in second language (L2) learning is associated with input conditions (Morgan-Short et al., 2010) as well as learners’ aptitude (Dörnyei, 2005). Recent work has demonstrated benefits of retrieval practice in promoting L2 learning of grammatical patterns and vocabulary in both artificial and natural languages (Hopman & MacDonald, 2018; Keppenne et al., 2021). With that said, when retrieval practice is based on oral recall as opposed to a recognition test, it confounds potential benefits of repeated testing (Rowland, 2014) with those associated with …

The Cognitive, Behavioral, Affective, And Physiological Components Of Social Cognition In Esports And Education, Daisy Reyes

Dissertations, Theses, and Capstone Projects

Prior research has shown that collaborative learning, or groups of two or more individuals working together towards a shared outcome, and Computer-Supported Collaborative learning has the potential to positively impact learning outcomes. This study aims to add to existing literature on collaborative learning by looking at how novices and experts learn and perform in esports (electronic sports) teams, or highly coordinated digital teams that often compete in stressful environments. Based on Carron’s Model of Cohesion in Sports Teams and Hanin’s Model of Individualized Zones of Optimal Functioning (IZOF), the current study looks at the relationship between cohesion (i.e., task and …

Gaze In Cats And Dogs, Michael Bogese

Theses and Dissertations

Domestic dogs (Canis lupus familiaris) developed many behaviors across domestication, one example being gaze behavior. Gaze is the crux of other behaviors that make dogs unique in human-animal dyads, including lookbacks, gaze-following, and participation in an oxytocin feedback loop. Gaze behavior may have been motivated and sustained by evergreen cooperative relationships between dogs and humans (e.g., hunting, service roles). One way to confirm this relationship is to compare dogs to a domesticated species that lacks a protracted history of companionship: the domestic cat (Felis catus). In this study, we compare the gaze duration to owners of …

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 …

Usability Of Health-Related Websites By Filipino-American Adults And Nursing Informatics Experts, Kathleen Begonia

Dissertations, Theses, and Capstone Projects

Filipino-Americans are an understudied minority group with high prevalence and mortality from chronic conditions, such as cardiovascular disease and diabetes. Facing barriers to care and lack of culturally appropriate health resources, they frequently use the internet to obtain health information. It is unknown whether they perceive health-related websites to be useful or easy to use because there are no published usability studies involving this population. Using the Technology Acceptance Model as a theoretical framework, this study investigated the difference between website design ratings by experts and the perceptions of Filipino-American users to determine if usability guidelines influenced the perceived ease …

Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

Dosage Matters: What Is Dosage, Doyoung Kim

Student Theses

To reduce recidivism, many correctional programs and interventions have been introduced to offenders. Though, the rate of recidivism remains exceedingly high. To improve program outcomes, it is important to match the dosage of a program to risk levels. However, there is not a standardized definition and measurement of program dosage. This thesis extends the study on identifying the definition and measurement of dosage and the effectiveness of the programs by conducting a systematic review of prior research. The results indicate that as a treatment dosage, treatment duration was more frequently used compared to treatment intensity to reduce recidivism rate of …

Are Delusions Beliefs?, Dorothy Reviss

Publications and Research

A belief is one’s personal attitude regarding an issue in the universe that contains evidence of truth to it. A delusion can be defined as a peculiar belief that contradicts reality, scientific evidence, and rational thinking, and may be attributed to personality disorders. In order to determine where a delusion is a belief, it is important to recognize the circumstances under which certain beliefs are held. While a delusion sounds similar to a false belief, it is an entirely unique phenomenon. In the case of personality disorders like the Capgras delusion, schizophrenia, and Reverse Othello syndrome individuals genuinely believe in …

Dopamine Neurons That Cotransmit Glutamate, From Synapses To Circuits To Behavior, Daniel Eskenazi, Lauren Malave, Susana Mingote, Leora Yetnikoff, Samira Ztaou, Vlad Velicu, Stephen Rayport, Nao Chuhma

Advanced Science Research Center

Discovered just over 20 years ago, dopamine neurons have the ability to cotransmit both dopamine and glutamate. Yet, the functional roles of dopamine neuron glutamate cotransmission and their implications for therapeutic use are just emerging. This review article encompasses the current body of evidence investigating the functions of dopamine neurons of the ventral midbrain that cotransmit glutamate. Since its discovery in dopamine neuron cultures, further work in vivo confirmed dopamine neuron glutamate cotransmission across species. From there, growing interest has led to research related to neural functioning including roles in synaptic signaling, development, and behavior. Functional connectome mapping reveals robust …

Accessibility Compliance And Assessments For Gateway Websites In Life Sciences: Toward Inclusive Design, Noreen Y. Whysel, Shari Thurow, Bev Corwin

Publications and Research

One main purpose of information architecture and site navigation is to enhance the effectiveness of user interfaces (UIs) by supporting and enabling task completion, accessibility, and sustainability. This is of particular importance for science gateways given the complexity of information on portal sites.

We examined the accessibility of 50 randomly selected gateway websites in the Life Sciences category in the Science Gateways Community Institute (SGCI) catalog, using both manual and automated methodologies. None of these sites produced an accessible website as per W3C, WCAG 2.1, and Section 508 standards. The most common accessibility success in these websites was URL structure, …
