Physical Engagement As A Way To Increase Emotional Rapport In Interactions With Embodied Conversational Agents, Ivan Gris Sepulveda

Open Access Theses & Dissertations

One of the major goals in research on embodied conversational agents (ECAs) is to increase the believability and perceived trustworthiness of agents. To improve the efficacy of the interaction between humans and ECAs, I focus on the development of rapport, which is a complex and extensive behavioral state of affinity, synchronicity, coordination and mutual understanding that is difficult to model, measure and interpret. I present our AGENT Framework and our ECA, Adriana, which is capable of speech recognition and gesture recognition over long periods of time. Our current system provides up to 60 minutes of human-ECA interaction in a jungle-survival …

The Window To The Bilingual Mind: Eye Movements Reveal Psycholinguistic Grain Unit Sizes Of Bilingual Spoken Word Recognition, Yu-Cheng Lin

Open Access Theses & Dissertations

Although there are common phonological units across different languages, previous studies have shown that individual differences of language proficiency affect sound unit preferences in monolingual and bilingual speakers. The cross-language lexical activation of phonological representations in bilingual minds can provide a great opportunity for testing hypotheses about how this key factor modulates the cross-linguistic phonological transfer across languages. In this study, I used the eye-tracking technique and quantitative methods (i.e., growth curve analysis and multilevel regression) to examine how individual differences in language proficiency affect cross-language phonological unit size transfer in Chinese-English bilinguals. Participants heard a spoken word and were …

Event Related Potentials In A Two Stimuli Auditory Oddball Task In Concussed College Athletes: A Linguistic Component Replication Study, Christopher Anthony Roosmalen

Open Access Theses & Dissertations

Concussions affect an estimated 1.6 to 3.8 million individuals annually and can result in persistent symptoms and cognitive impairments in attention and memory. Concussions are a rising health concern especially in concussion management. Event Related Potentials (ERP) may more accurately assess cognitive recovery making better return to play decisions. In 2013, Sanchez found no significant difference between concussed athletes and non-concussed individuals in the in amplitude of the P300 ERP component using an auditory oddball task consisting of 2 different consonant, vowel (CV) syllables. Because participants were instructed to maintain a mental and verbal count of the target stimuli, a …

The Effects Of Baby Sign Training On Child Development, Bethany Iris Urquidi

Open Access Theses & Dissertations

Introduction: Baby sign has gained the attention of many researchers and parents. Relatively little is known about the use of baby sign and the impact it has on the development of children. As the use of baby sign increases in popularity, research studies have had limited and inconsistent results regarding its influence. Purpose: The purpose of this study is to measure the effects of baby sign training on the overall development of normally hearing children while improving on the limitations of current studies (between group study). Methods: Participants in the study included 22 children, ages 6 months to 2 years; …

Virtual Rapport With Extraverted Agents, Jacqueline Brixey

Open Access Theses & Dissertations

Studies from psychology conclude that "birds of a feather flock together"- or, in other words, people tend to seek companionship with those who have a similar personality to their own. Researchers in the fields of Linguistics and Psychology have found numerous markers that differentiate the dialogue of extroverts from that of introverts. Recent work in Human Computer Interaction has sought to understand the nature of creating and maintaining rapport between humans and Embodied Conversational Agents (ECAs).

Seeking an interdisciplinary approach that combines knowledge from HCI, Linguistics, and Psychology, I sought to establish whether introverted users report the highest level of …

Acculturation, Psychological Distress, And Smoking In Latinos Living With Hiv/Aids, Jessica Armendariz

Open Access Theses & Dissertations

In the United States smoking cigarettes is the leading cause of preventable death, and smoking is of particular health concern among people living with HIV. Depression has been consistently linked to smoking in the literature, and data indicate that acculturation to the U.S. is associated with increased depression among Latinos.

This study examined if acculturation moderates the impact of depression on smoking behavior among Latinos living with HIV through the mediating effect of social support. The results may extend to the sociopsychological construct of culture. We studied 300 Latinos who live with HIV on the U.S./Mexico border.

Results demonstrated there …

La Lutte Pour L'Azawad: Mnla Public Relations Responses To Conflict In Northern Mali, 2011-2014, Sean Neil Curtis

Open Access Theses & Dissertations

This Thesis examines the Internet public relations content of Mali's Tuareg rebel group, the Mouvement National de la Liberation de L'Azawad (MNLA). Content analysis grounded in speech act securitization theory is applied to the 259 posts on the MNLA's primary French language website in order to determine if MNLA website posts correlate with the events occurring in the northern Mali conflict. The data reveals that various characteristics of MNLA statements do correlate with events in the conflict. What the MNLA says provides important insight into the organization and the conflict itself. The identified correlations allow for MNLA rhetoric and activity …

The Nigerian Economy And The Dutch Disease., Kenechukwu Daryl Nweke

Open Access Theses & Dissertations

Dutch Disease explains the relationship between exploitation of natural resources and the decline in the agricultural and manufacturing sectors. The dependent variable of the model shows the contraction of either the manufacturing or agricultural sector. The theory asserts that increase in revenues from natural resources will de-industrialize a nationâ??s economy by appreciating the real exchange rate, and exports on the booming commodity, which in turn makes the tradable sector less competitive.

The government of Nigeria has neglected the agriculture sector, causing the sector to be less competitive in the trade market. As a result, when economic activities in Nigeria increase …

The Impact Of Baby Sign Training On Stress Levels Of Daycare Providers, Grisel Julieta Rodriguez

Open Access Theses & Dissertations

Proponents of baby sign claim improvements in child-caregiver interactions and reductions in parental stress as benefits of implementing baby sign. Due to research contradicting the claims, and to the rise in daycare attendance, the current study investigated the effects of a baby sign workshop on the stress perception of daycare providers. A pre-test post-test between groups design with 20 participants was conducted using the Perceived Stress Scale (PSS10) and a workshop-specific descriptive survey as measures. The difference between the post-test stress levels of experimental and control groups approached significance, as did the differences between pre-test and post-test results for the …

The Contribution Of Mild Traumatic Brain Injury/Concussion To The Development Of Post-Traumatic Stress Disorder Symptoms, Kylie Lauren Marshall

Open Access Theses & Dissertations

A controversial issue is whether TBI is a necessary precursor to the development of PTSD symptoms, or if the two variables are mutually exclusive. Recent rodent-models reveal that a stressful environment cannot cause PTSD symptoms directly without TBI, yet it is unknown if PTSD symptoms can develop following a TBI. This study provides a potential analogue to study this relationship by evaluating the effects of sports-related concussion. Purpose: This study investigated two questions, 1) Is there a significant difference in the frequency of PTSD symptoms reported by athletes at baseline (BL) testing and post-concussion (PC) testing over time? 2) Is …

Processing Of Language Switches In Bilingual Individuals With Aphasia: An Event-Related Potential Comparison, Lizette Rodarte

Open Access Theses & Dissertations

Switching between languages, or code-switching, is a common phenomenon in bilingual individuals. In proficient bilinguals, these switches are done with ease and are used for many purposes. Contrary to popular belief, these switches are rule-governed and follow grammatical structure. Bilingual individuals diagnosed with aphasia present with difficulty processing languages and these language switches. With the increase in bilingual individuals, it is likely that the speech-language pathology community will see an increase of bilingual individuals with aphasia on their caseload. For this reason, the purpose of this study is to increase our understanding of the neural processes involved in processing of …

The Impact Of Accented English On Speech Comprehension, Benigno Valles

Open Access Theses & Dissertations

ABSTRACT

In the context of shifting demographics in the United States and with an increasing multicultural workforce, the verbal exchange of information is vital especially between health care providers and patients. Although English is the official language in the United States, many individuals from different national origins speak English with some degree of accent. Before we can address health care provider/patient communication, it is necessary to investigate the potential impact of accented English on speech comprehension and its implications on basic communicative interactions. The verbal exchange of information between health care providers and patients is important in diagnostics, treatment, patient …

The Effects Of Sign On Speech Segmentation In Infants, Alma Rosa Acosta

Open Access Theses & Dissertations

Introduction: The ability to extract words from fluent speech (speech segmentation), perhaps one of the greatest obscure achievements for the purpose of learning language, is dependent upon imperceptible endeavors. Remarkably, infants are active participants from the moment they are born, using auditory and visual information to assist them segmenting speech. As motivated parents attempt to use baby sign to bridge communication gaps, visual information in the form of baby sign may benefit children in extracting words from speech. To examine the effects of baby sign on speech segmentation, a systematic replication of the Hollich et al. (2005) study, a within-subject …

Challenges In Assessing College Students' Conception Of Duality: The Case Of Infinity, Grace Olutayo Babarinsa-Ochiedike

Open Access Theses & Dissertations

Interpreting students' views of infinity posits a challenge for researchers due to the dynamic nature of the conception. There is diversity and variation among students' process-object perceptions. The fluctuations between studentsâ?? views however reveal an undeveloped duality conception. This study examined college students' conception of duality in understanding and representing infinity with the intent to design strategies that could guide researchers in categorizing students' views of infinity into different levels.

Data for the study were collected from N=238 college students enrolled in Calculus sequence courses (Pre-Calculus, Calculus I through Calculus III) at one of the southwestern universities in the U.S. …

At The Intersection Of Deferred Action For Childhood Arrivals, The Migration Trust Network And Labor, Mario Javier Chavez

Open Access Theses & Dissertations

This study unpacks the intersection of Deferred Action for Childhood Arrivals, the Migration Trust Network and Labor. I use 9 in-depth qualitative interviews to address how such policies are affecting the labor acquisition and labor outcomes of DACA recipients. The Migrant trust network remained important for DACA recipients, although in a more indirect and macro-level way than described in Flores-Yeffal (2013). In particular, DACA recipients relied on the collective efficacy embedded within the community to facilitate their job search. Additional, migrant trust networks function differently according to the DACA recipients' level of education, but to fully benefit from the advantages …

Immigration And Family Violence At The Household Level Of Analysis: Examining The Effects Of Immigrant Culture And Neighborhood Structure, Jorge Luis Hernandez

Open Access Theses & Dissertations

This study concerns the relationship between immigration and family violence at the household level of analysis. Previous studies have suggested that immigrant status - particularly first generation immigrant status - is not associated with crime. However, the same cannot be said about their descendants the second and third generations; as they are not as insulated from crime as their forefathers. This study measures the following variables which are relevant to the immigration and family violence relationship; immigrant generational status, acculturation levels, patriarchy, family oriented values, collective efficacy, surveillance, and measures of informal social control. This study finds that there is …

Memory, State Violence, And Revolution: Mexico's Dirty War In Ciudad Juárez, Vanessa Claire Johnson

Open Access Theses & Dissertations

After the uprising that took place in Madera, Chihuahua on September 23, 1965, the first armed challenge to the state since the Mexican Revolution, the north became a region of historical significance for understanding the subsequent "Dirty War" that spanned from the late 1960s to the early 1980s. Ciudad Juárez was a key locale in which a wide variety of revolutionary groups conducted both open and clandestine activities. Attempting to rouse the masses, a dedicated few organized protests, counter-meetings, popular assemblies, and launched a prepa popular to reorganize and democratize education. The Mexican state responded to these events with repression, …

Japanese Computational Lexicon: A Computational Dictionary Of Japanese Verb Forms, Mayumi Kobayashi

Open Access Theses & Dissertations

This paper presents two main topics: a linguistic analysis of Japanese morphological lexicon focused on verb conjugation and a computational analysis of Japanese verb conjugation in Prolog programming. Prolog is one of the computer programming languages and is used to solve a problem logically with a number of statements called "clauses," which are defining various relationships of the entities. With respect to the linguistic aspect, this paper discusses Japanese verb formation, its conjugation patterns, twelve basic forms of Japanese verbs, and a Japanese morphophonemic process called “音便 (onbin)” by investigating 304 regular verbs and 2 irregular verbs. Among the several …

Pre-Service Elementary Teachers' Affective Dispositions Toward Mathematics, Benjamin R. Mcdermott

Open Access Theses & Dissertations

The purpose of this study was to measure and report pre-service elementary teachers' affective domain of productive disposition toward mathematics during the semester they were enrolled in a reform-based mathematics methods course. The study attempted to observe and report dynamic and enduring aspects of disposition as well as the perceived reasons for any changes, or lack thereof, in disposition. The rationale for focusing on disposition is related to Kilpatrick, Swafford, and Findell's (2001) inclusion of productive disposition as one of the five interdependent strands of the mathematical proficiency conceptual framework. Furthermore, it has been argued that dispositions develop at very …

Study Design: This study used a group design pre-test information group and a post-test information group matched for age.

Methods: Prior to cognitive testing, the athletes were divided into an experimental and control group. The experimental group received information about concussions before taking the cognitive test. The control group did not receive concussion information before cognitive testing. Both groups completed a questionnaire following testing that asked: "Based on your experience here today, …

The Effects Of Task Demands And Word Frequency On Language Source Encoding, Elva Natalia Strobach Oronoz

Open Access Theses & Dissertations

Source memory effects have been relatively unexplored in bilingual memory. Bilinguals have to perform certain source encoding operations to successfully determine the appropriate language from context. These operations have not been examined from a long-term memory perspective, and are not incorporated into models of source monitoring. Further, language source information is not incorporated into the major models of bilingual language processing. Five experiments examined bilingualsâ?? language source monitoring for low- and high-frequency words in English and Spanish. Each experiment placed different processing demands on participants. In Experiment 1, participants studied a mixed-language word list, then were subsequently tested for language …

The Effects Of Baby Sign On Child Development, Joanna Scott

Open Access Theses & Dissertations

Introduction: Although the popular media supports the use of baby sign for enhanced developmental outcomes of children, empirical research verifying the actual effects of baby sign on the areas of communicative, cognitive, social, and physical development, is limited. Advocates of baby sign suggest pre-lingual symbolic communication may result in accelerated development whereas critics claim definitive conclusions cannot be drawn because of flawed methodology in the research. Purpose: The purpose of the present study was to explore whether baby sign has an impact on the developmental growth of children. Methods: Using a between groups research design, assessment data were obtained from …
