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 …

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 …

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 …

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 …
