A Comparison Of Two Variations Of A Stimulus-Stimulus Pairing Procedure On Novel And Infrequent Vocalizations Of Children With Autism, Andrew J. Bulla

Masters Theses

Despite the growth in a behavioral technology for the treatment of autism, a small population of individuals with autism fails to develop functional language. One procedure used for inducing vocalizations in non-verbal children is a stimulus-stimulus pairing (SSP) procedure. In an SSP procedure a vocalization is paired with a reinforcer over a period of time to establish the vocalization as a learned reinforcer, and any utterance of the target vocalization is believed to be automatically reinforced thus increasing the frequency of the vocalization. Past research has yielded mixed results with the SSP procedure, and more research is warranted to identify …

Integrating Visual Mnemonics And Input Feedback With Passphrases To Improve The Usability And Security Of Digital Authentication, Kevin Juang

All Dissertations

The need for both usable and secure authentication is more pronounced than ever before. Security researchers and professionals will need to have a deep understanding of human factors to address these issues. Due to their ubiquity, recoverability, and low barrier of entry, passwords remain the most common means of digital authentication. However, fundamental human nature dictates that it is exceedingly difficult for people to generate secure passwords on their own. System-generated random passwords can be secure but are often unusable, which is why most passwords are still created by humans. We developed a simple system for automatically generating mnemonic phrases …

Bilingualism And Age Of Onset Of Alzheimer's Disease And Vascular Dementia In Hispanic Americans, Deborah M. Lawton

Theses and Dissertations - UTB/UTPA

Studies have linked bilingualism to later age of onset of Alzheimer’s disease in comparison to monolinguals. It has been theorized that in bilinguals inhibitory control is consistently used to suppress one language, leading to enhanced executive functioning and an increase in cognitive reserve. The effect of bilingualism on age of diagnosis was investigated retrospectively using data from the Sacramento Area Latino Study on Aging. This involved a longitudinal cohort of 1,789 Hispanic Americans > 65 years of age. Within the cohort there were 128 cases of dementia: 85 diagnosed with Alzheimer’s disease and 43 diagnosed with vascular dementia. Analysis of variance …

Effects Of Internalizing Behaviors On Processing Speed And Academic Fluency, Kristen Bjork

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study explored the relationships between internalizing behavior problems, processing speed and academic fluency. Internalizing behaviors are behaviors typically associated with depression and anxiety, such as withdrawal, somatization, and excessive worry. This study focused on the impact of these behaviors on an individual's ability to efficiently process information, as well as perform simple academic tasks quickly. The following measures were used: WISC-IV Coding and Symbol Search scores as a measure of processing speed, WJ-III Tests of Achievement Math Fluency and Reading Fluency scores as measures of academic fluency, and BASC-2 Parent Rating Scale scores for internalizing behaviors. Data gathered from …

Impaired Theory Of Mind In Psychotic And Affective Disorders, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychotic symptoms in bipolar I disorder during mood episodes has been associated with several negative outcomes raising the question as to whether psychosis is a risk factor for a more severe form of this chronic and debilitating condition. However, relatively little research has been directed at understanding the relationships among social cognitive functioning in bipolar I disorder with and without a history of psychosis. Impaired social cognition has been identified as a putative endophenotypic markers in schizophrenia and the evidence is mounting as to whether similar impairments also exist in bipolar I disorder. Given the plethora of research supporting the …

Reducing Court-Related Stress Through Court Education: Examining Child Witnesses, Attorneys And Parents, Brittnie Turquoise Watkins

UNLV Theses, Dissertations, Professional Papers, and Capstones

Court education presents a useful approach to addressing children's stress, anxiety or fear related to testifying. The current study uses a pretest-posttest design to evaluate whether Kids' Court School (KCS), a court education program in Clark County, Nevada, reduces court-related stress in child witnesses. In addition, attorneys' and parents' concerns related to various elements of the child's impending testimony, are evaluated. The measure used to assess stress was the Court-Related Stress Scale (CRSS), a 10-item Likert scale adapted from the Stressfulness of Life Scale. In addition, open-ended questions were posed at the time of posttest. The CRSS was administered to …

Executive Control In Hispanic Children: Considering Linguistic And Sociocultural Factors, Miriam M. Martinez

Department of Psychology: Dissertations, Theses, and Student Research

Executive control represents a collection of high-order cognitive processes that are associated with important child outcomes, including academic achievement and social competencies. Despite the burgeoning interest in examining the development of executive control, less is known about the development of these skills among ethnic minority children. Hispanic children are currently the largest ethnic minority group in the United States and their diverse sociocultural and linguistic backgrounds provide an excellent context to study the influence of linguistic and sociocultural factors on the development of child executive control. The purpose of the three complementary studies reported in this dissertation is to contribute …

Looking At The Multiple Meanings Of Numeracy, Quantitative Literacy, And Quantitative Reasoning, H. L. Vacher

Numeracy

The subject of this journal goes by a variety of names: numeracy, quantitative literacy, and quantitative reasoning. Some authors use the terms interchangeably. Others see distinctions between them. Study of psycholinguistic and ontological concepts laid out in the literature of WordNet and familiarity with the papers in this journal suggests a vocabulary matrix consisting of four rows (word senses) and three columns (word forms, namely numeracy, QL, and QR). The four word senses correspond to four sets of synonyms: {numeracy}, {numeracy, QL}, {QL, QR}, and {numeracy, QL, QR}. Each of the word forms is polysemous: “numeracy” points to the first, …

Persistent Emotional Extremes And Video Relay Service Interpreters, Dawn M. Wessling, Sherry Shaw

Journal of Interpretation

This mixed methods study explored how call content emotionally affects video interpreters (VIs) who work in Video Relay Service (VRS) and how this influences perceptions of job satisfaction and general well-being. The participants included 889 self-reported VIs who completed a survey containing open and closed-ended questions regarding their work. Whereas VRS call content can be extremely emotional for the non-deaf and deaf callers, whether positive or negative, the study seeks to identify a spectrum of coping strategies to perceived stressors brought about by these emotionally charged incidents. The study examined the frequency of these types of calls processed by the …

Secondary Teachers' Perceived Role In Suicide Prevention And Intervening With Suicidal Students, Victoria R. Hatton

Theses and Dissertations

Best practices in adolescent suicide prevention include teachers as major participants, because teachers are in a unique and frontline position to support students. Unfortunately, many teachers are unaware of their role in suicide prevention efforts. In addition to confusion about their roles, teachers may feel uncomfortable and/or lack confidence in their abilities to identify warning signs and intervene with suicidal students. This study assessed secondary teachers' (N = 74) perceptions of their role in suicide prevention as well as how they perceive their comfort and confidence levels in identifying and intervening with suicidal students. In addition, this study explored possible …

Time Travel With Gilles Deleuze, John M. Winslade

Special Education, Rehabilitation & Counseling Faculty Publications

My focus here will be on working in therapy with an elastic concept of time built on Deleuze’s readings of time as a synthesis of the past, present and future. This interest has particular value for the construction of remembering conversations. I shall speak to the value I can see for this field of practice. The poststructuralist philosopher Gilles Deleuze has much to offer narrative practice through the concepts he developed. I intend to explore some specific aspects of his reconceptualization of time in this presentation.

Artificial Neural Network Approach For Revealing Individuality, Group Membership And Age Information In Goat Kid Contact Calls, Livio Favaro, Elodie F. Briefer, Alan G. Mcelligott

Sentience Collection

Machine learning techniques are becoming an important tool for studying animal vocal communication. The goat (Capra hircus) is a very social species, in which vocal communication and recognition are important. We tested the reliability of a Multi-Layer Perceptron (feed-forward Artificial Neural Network, ANN) to automate the process of classification of calls according to individual identity, group membership and maturation in this species. Vocalisations were obtained from 10 half-sibling (same father but different mothers) goat kids, belonging to 3 distinct social groups. We recorded 157 contact calls emitted during first week, and 164 additional calls recorded from the same individuals at …

This project examined associations between engagement in a community-based integral practice program and measures of health and well-being. In this prospective withinsubjects uncontrolled cohort study, 53 participants of Integral Transformative Practice (ITP), a program that incorporates movement, nutritional and exercise recommendations, affirmations, contemplative introspection, theory and philosophy, and group discussions and activities, were followed over one year. Participants completed online questionnaires upon enrollment, at six months, and one year later. Repeated measures analyses showed that participants reported improved overall health and reduced symptoms of ill health, as well as increased psychological well-being, vitality, and quality of life over the course …

What We Thought We Knew: Intellectual Assessment Of Individuals Who Are Blind, Richard L. Sylvester Jr.

Doctoral Dissertations

Throughout the history of intellectual assessment, research involving individuals who are blind has often been scarce. Currently, there are no intellectual assessment procedures based on the Cattell-Horn-Carroll (CHC) theory of intelligence available to individuals who are blind. CHC theory is considered to be the gold standard of intellectual assessment and many government and diagnostic policies rely upon CHC theory. The proposed research sought to extend the current reach of CHC theory to individuals who are blind by developing a new measure of tactile performance ability. The Tactile Assessment of Performance (TAP) was developed and administered to participants who were blind …

Ask A Busy Person: Attentional Myopia And Helping, Matthew Richard Wallaert , '05, Andrew Ward, T. Mann

Psychology Faculty Works

According to an oft-quoted piece of folk wisdom, if one wants something accomplished, the best person to ask is a busy person. We tested a version of this proposition in two studies. Study 1 exposed participants to a helping request in which cues promoting the relevant behavior were made more salient than those inhibiting it. Study 2 featured a request in which inhibiting cues were made more salient than cues promoting the behavior. In both studies, participants who were "busied" by high cognitive load showed more influence of the dominant behavioral pressure than did participants under minimal load. The results …

Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston

Open Access Theses

Compensation for coarticulation is the extent in which an individual perceives the contextual variations of speech. When presented with an ambiguous consonant-vowel segment (e.g., a consonant halfway between /sa/ and /∫a/) research illustrates that a listener is likely to compensate for coarticulation with the following vowel. Therefore, a listener will be more likely to report an ambiguous speech sound as /s/ when it occurs before [u] than before [a]. Previous results have suggested that, within neurotypical individuals, the degree to which individuals compensate for coarticulation may be related to their Autism Quotient (AQ; Yu, 2010). However, this research did not …

Is Maternal Touch Used Referentially?, Rana Abu-Zhaya

Open Access Theses

Early social interactions are highly multimodal and include a wealth of cues (e.g., speech, facial expressions, motion, gestures and touch). Infant-directed speech (IDS) by itself may aid in language development. Touch by itself has been also shown to play an important role in dyadic interactions affecting both the infant and the caregiver. However, little is known about the impact of the combination of these two modes of communication on infant language development. In this thesis, I hypothesize that caregiver touch is provided in synchrony with speech, providing the language-learning infant with cues that may not only help her to find …

The Importance Of Community Resilience: Developing The American Red Cross International Services Department In The New Hampshire Region, Sarah Romac

Capstone Collection

Disaster management and humanitarian aid organizations have had to reevaluate how communities and individuals can better adapt and prepare for future disaster events. One concept organizations are incorporating into their overall framework is strengthening community resilience. Increasing a community’s resilience level increases its ability to cope with the changes that affect it. Creating awareness of the vulnerabilities in an area, addressing these vulnerabilities with preparedness training, disaster risk reduction (DRR), and sustainable changes made over the long-term can develop a community’s adaptive capacity to be more resilient.

For my practicum, I was given the opportunity to be the International Services …

Emerging From The Shadows: Civil War, Human Rights, And Peacebuilding Among Peasants And Indigenous Peoples In Colombia And Peru In The Late 20th And Early 21st Centuries, Charles A. Flowerday

Department of Anthropology: Theses and Student Research

Peacebuilding in Colombia and Peru following their late-20^th and early 21^st century civil wars is a challenging proposition. In this study, it becomes necessary as indigenous peoples and peasants resist domination by extractive industries and governments in their thrall. Whether they protest nonviolently or rebel in arms, they are targeted for human-rights violations, especially murder, disappearance and displacement. The armed actors, state, insurgency, paramilitaries or drug traffickers, destroy civic institutions (local or regional government) and the civil (nonprofit) sector and replace them with their own authoritarian versions. Therefore, peacebuilding has emphasized rebuilding civic institutions, civil society and local …

The Role Of Multicultural Competence, Privilege, Attributions, And Team Support In Predicting Positive Youth Mentor Outcomes, Rachael Leigh Suffrin

College of Science and Health Theses and Dissertations

In the current study we use Bronfenbrenner’s (1979) ecological theory to guide an inquiry into how the social environment surrounding mentors’ matters in regards to mentor outcomes of satisfaction, retention, and extra-role pro-social behavior (i.e., mentors willingness to go above and beyond for their mentee or the mentoring program). Mentors are sampled from mentoring organizations across the United States. Drawing from Bronfenbrenner’s ecological theory (1979), we examine mentors embedded in distinct micro- and macrosystems. At the microsystem level we explore how the relationship between the mentor and the (a) mentee, (b) mentees’ family, and (c) the mentoring team may predict …

Pre -Service School Psychologists' Racial And Weight-Related Biases And The Relationship That Taking Diversity Courses Has On These Biases, Shaerica Jackson

Theses and Dissertations

Past research has shown that racial and weight-related biases are present in school settings and can have a negative impact on students. The purpose of this study was to assess the impact of racial and weight-related biases upon judgments that school psychology graduate students make about Black and overweight students who were having problems in school. The problematic behaviors exhibited by the student in the case study were based on symptoms often seen in children with Attention-deficit/Hyperactivity Disorder (ADHD). We also examined the extent to which implicit and/or explicit attitudes moderated the degree of school psychology graduate students' attributions of …

A Cross-Species Study Of Gesture And Its Role In Symbolic Development: Implications For The Gestural Theory Of Language Evolution, K. Gillespie-Lynch, P. M. Greenfield, Y. Feng, S. Savage-Rumbaugh, H. Lyn

Faculty Publications

Using a naturalistic video database, we examined whether gestures scaffold the symbolic development of a language-enculturated chimpanzee, a language-enculturated bonobo, and a human child during the second year of life. These three species constitute a complete clade: species possessing a common immediate ancestor. A basic finding was the functional and formal similarity of many gestures between chimpanzee, bonobo, and human child. The child's symbols were spoken words; the apes' symbols were lexigrams - non-iconic visual signifiers. A developmental pattern in which gestural representation of a referent preceded symbolic representation of the same referent appeared in all three species (but was …

Effects Of Phonological Neighborhood Density On Lexical Access In Adults And Children With And Without Specific Language Impairment, Diana Almodovar

Dissertations, Theses, and Capstone Projects

The present study was designed to examine how adults, children with typical language development (TLD), and children with Specific Language Impairment (SLI) process words from sparse and dense phonological neighborhoods, using the Cross Modal Picture-Word Interference Paradigm. The participants were asked to label a picture presented on a computer screen, while ignoring auditory distractors (interfering words or IWs) presented over headphones. The target items were manipulated according to neighborhood density (high and low density words), and the auditory distractors were either identical to the target, a neutral distractor (good), phonologically related (by rhyme), or unrelated to the target item. The …

Between Sites: Critical Convergences At The Personal, Interpersonal, And Institutional Levels In A Service Learning Course, Kendra Rashaun Brewster

Dissertations, Theses, and Capstone Projects

Set within the context of the increasing emphasis on civic engagement and transformative education, this work addresses service learning as a form of civic engagement that holds both the risks of acriticality and critical potential. This study examines the capacity for the critical consciousness and relationality that define the primary commitments of critical service learning (see Kinefuchi, 2010). Thus, this study is grounded in the ways that the circuits of privilege and dispossession were breached in a service learning course where college students travelled to mentor adolescent girls who were in a secure residential facility. The narratives of former service …

Yes We Can: A Dyadic Investigation Of Cognitive Interdependence, Relationship Communication, And Optimal Behavioral Health Outcomes Among Hiv Serodiscordant Same-Sex Male Couples, Kristine Elizabeth Gamarel

Dissertations, Theses, and Capstone Projects

Research suggests that couples who adopt a "we" orientation in relation to illness demonstrate greater resiliency and an increased capacity to cope with stressors. HIV serodiscordant couples (one partner is HIV-positive, the other is HIV-negative) have been identified as a critical mode of HIV transmission. The present study integrates dyadic coping models and interdependence theory to examine whether cognitive interdependence (i.e., the extent to which couples include aspects of their partner into their self-concept) and communication strategies are associated with sexual behavior, antiretroviral therapy (ART) adherence, depressive symptoms, sexual satisfaction, and relationship satisfaction. The study also tested whether the associations …

Co-Constructing Cultural Attunement With Latino Clients In Couple Therapy, Marco Antonio Elias-Juarez

Loma Linda University Electronic Theses, Dissertations & Projects

There is a need for culturally attuned approaches for couple’s therapy with Mexican/ Mexican-American people (Falicov, 2009). However, there have been few theoretical frameworks to conceptualize cultural attunement, and attunement has been primarily understood as a skill or as an attitude rather than as a relationship or as a series of clinical concepts with steps to follow (Hoskins, 1999; Oakes, 2011). From the social constructionist perspective, cultural attunement is related to the cultural context and cultural interactions that shape beliefs and attitudes about what is meaningful in establishing deep relationships for Latino and non-Latino therapists and their Mexican and Mexican-American …

Guidelines For Culturally Based Interventions With Healthcare Professionals, Ifeanyi Anthony Onyemenem

Loma Linda University Electronic Theses, Dissertations & Projects

Early detection is critical to surviving breast and cervical cancer. Unfortunately, Latin American (Latino) women in the United States are more likely to be diagnosed at later stages of cancer and have poorer rates of repeat screenings when compared to non-Latino White (Anglo) women. One factor identified through research that negatively affect continuity of cancer screening is perceived mistreatment. Guided by Betancourt’s integrative model of culture, psychology and behavior, the current project proposes guidelines for developing culturally informed interventions with healthcare professionals that take into account the socially shared values, beliefs and norms that negatively impact breast and cervical cancer …

Narrative Conflict Coaching, Ashley J. Pangborn

Electronic Theses, Projects, and Dissertations

ABSTRACT

Narrative conflict coaching is a counseling technique which focuses on separating clients from their problems and encouraging them to see their lives and futures from new perspectives. It has been used in a variety of arenas and is consistent with other practices within the field of narrative conflict resolution, such as narrative mediation. In this project I utilized qualitative research methods to analyze the immediate effectiveness of conflict coaching questioning techniques within the setting of a counseling conversation. The analysis focuses on the detail of the process of narrative conflict coaching more than on the final outcomes. The data …

Predicted Causality In Decision Making: The Role Of Culture, C Dominik Guess, Bernadette Robinson

Psychology Faculty Research and Scholarship

In the wider sense, decision making is embedded in the problem-solving process and its many stages (Davidson and Sternberg, 2003; Güss et al., 2010). In the narrow sense, decision making is understood as the ability to select one of several alternatives and to act accordingly (Güss 2004). Previous research has often focused on decision making in relatively predictable environments with clear goals (e.g., expected utility theory of von Neumann and Morgenstern, 1944). In recent decades the focus has been on decision making heuristics, i.e., strategies or rules of thumb, applied in uncertain situations (e.g., Tversky and Kahneman, 1974; Simon, 1979; …
