The Stability Of The Speech-To-Song Illusion And Individual Differences, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music and language are easily distinguishable for the average listener despite sharing many structural acoustic similarities. The Speech-to-Song illusion can give rise to both musical and linguistic percepts by inducing a perceptual switch after listening to multiple repetitions of a natural spoken utterance. As such, it has been used as a tool to control for low-level acoustic characteristics previously shown to drive lateralized brain responses regardless of domain-type, helping to disambiguate the contribution of high- versus low-level processes in both music and speech perception. However, there exists a lack of research on how large a role individual differences such as …

Identifying Risk Factors For Ptsd Symptom Clusters In Maltreated, Multiracial Youth Using Nonparametric Modeling, Mallory Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Multiracial youth are one of the most at-risk racial groups for child maltreatment. Multiracial individuals are also more likely to report mental health concerns than other racial or ethnic groups. This study aimed to identify demographic and psychological risk factors that are unique to multiracial, maltreated youth with respect to PTSD symptoms (i.e., re-experiencing, hyperarousal, avoidance) through classification and regression tree (CART) analyses. Participants included 99 multiracial, maltreated youth directly following their placement in an emergency group shelter due to substantiated maltreatment. The first hypothesis was that female gender, English first language, questions related to guilt and self-blame, and depressive …

Multiple Approaches To Auditory Rhythm: Development Of Sustained Musical Beat And The Relation To Language, Development Of Rhythmic Categories Via Iterated Production, And A Meta-Analytic Study Of Neural Entrainment To Beat, Karli Marie Nave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rhythm is ubiquitous to human communication, coordination, and experience of music. In this dissertation, I address three empirical questions through three different methodologies, all of which contribute to the growing body of literature on human auditory rhythm processing. In Chapter 2, I present a registered report detailing the results of independent conceptual replications of Nozaradan, Peretz, Missal, & Mouraux (2011), all using the same vetted protocol. Listeners performed the same tasks as in Nozaradan et al. (2011), with the addition of behavioral measures of perception. In neuroscience, neural correlates to musical beat perception have been identified, yet little to no …

Solution-Focused Zone Of Proximal Development: A Vygotskyan Contribution To Solution-Focused Therapy, Stephanie Freeman

Journal of Solution Focused Practices

This theoretical paper explores the possibility of combining principles of solution-focused therapy with theories of learning and development by the psychologist Lev Vygotsky, whose thinking led to the development of Cultural-Historical Activity Theory. The similarities and complementaries between these traditions merit attention. Further, SFT has been characterized as an eclectic and constantly evolving approach, the theoretical and philosophical foundations of which are somewhat scattered. Hence, the article attempts to redefine the philosophical and theoretical location of SFT through a “Vygotskyan and CHAT-informed” lens. Since the emphasis in SFT seems to be on the identification and detailed description of the client’s …

Social Media, Stress And Sleep Deprivation: A Triple “S” Among Adolescents, Micajah Daniels, Manoj Sharma, Kavita Batra

Environmental & Occupational Health Faculty Publications

This commentary is aimed to discuss the impact of social media or the internet and engagement on youth development and comprehend these complex interrelationships. The discussion will serve as an important basis for designing targeted interventions to promote the judicious use of social media and meaningful engagement among youth. Problematic social media use (SMU) among adolescents may be associated with sleep deprivation, emotional distress, and adoption of maladaptive behaviors. Depression and stress are most notably connected to online harassment from SMU or cyberbullying. Degradation, threats, fake profiles, cyberstalking and unwanted comments are some examples of cyberbullying. Given the critical developmental …

Musical Meter: Examining Hierarchical Temporal Perception In Complex Musical Stimuli Across Human Development, Sensory Modalities, And Expertise, Jessica Erin Nave-Blodgett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Performing, listening, and moving to music are universal human behaviors. Most music in the world is organized temporally with faster periodicities nested within slower periodicities, creating a perceptual hierarchy of repeating stronger (downbeat) and weaker (upbeat) events. This perceptual organization is theorized to aid our abilities to synchronize our behaviors with music and other individuals, but there is scant empirical evidence that listeners actively perceive these multiple levels of temporal periodicities simultaneously. Furthermore, there is conflicting evidence about when, and how, the ability to perceive the beat in music emerges during development. It is also unclear if this hierarchical organization …

Predictors Of Adolescents’ Interest In Stem Majors And Careers, Ei Myint

Calvert Undergraduate Research Awards

Advanced Research Winner 2019:

The United States currently faces a shortage of qualified workers in fields related to science, technology, engineering, and math (STEM). The first critical step in preventing the labor shortage in STEM is understanding the factors that guide adolescents toward STEM pursuits. Drawing on Eccles’ expectancy-value theory (EVT), the current study aims to identify factors that are relevant to adolescents’ interest in STEM majors and careers. Data were collected from 629 adolescents (M_age = 16.09). Participants attended a high school in northern California and predominantly identified as Asian American (82% of the sample). Preliminary analyses …

Conversational Movement Dynamics And Nonverbal Indicators Of Second Language Development: A Microgenetic Approach, Kristine Marie Bragg

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation study extends on current understandings of gesture and embodied interaction with the eco-social environment in second language development (SLD) while introducing new aspects of movement analysis through dynamical modeling. To understand the role of embodiment during learning activities, a second language learning task has been selected. Dyads consisting of a non-native English-speaking student and a native English-speaking tutor were video recorded during writing consultations centered on class assignments provided by the student. Cross-recurrence quantification analysis was used to measure interactional movement synchrony between the members of each dyad. Results indicate that students with varied English proficiency levels synchronize …

Gambling Education Programs For Adolescents: A Systematic Review, Brittany Keen, Alex Blaszczynski, Fadi Anjoul

International Conference on Gambling & Risk Taking

Around two thirds of Australian adolescents aged 10-14 years old have gambled in the last year, and rates of problem gambling are up to four times higher among adolescents than in the adult population. Schools provide a unique opportunity to intervene in cognitive and behavioural development, and while several gambling education programs exist in schools across Australia and internationally, few have been empirically evaluated. The purpose of this review was to provide a systematic appraisal of the published research on gambling education programs for adolescents. The review aimed to identify the number and quality of studies that have evaluated gambling …

Building Categories To Guide Behavior: How Humans Build And Use Auditory Category Knowledge Throughout The Lifespan, Christina M. Vanden Bosch Der Nederlanden

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although categorization has been studied in depth throughout development in the visual domain (e.g., Gelman & Meyer, 2011; Sloutsky 2010), there is little evidence examining how children and adults categorize everyday auditory objects (e.g., dog barks, trains, song, speech) or how category knowledge affects the way children and adults listen to these sounds during development. In two separate studies, I examined how listeners of all ages differentiated the multidimensional acoustic categories of speech and song and I determined whether listeners used category knowledge to process the sounds they encounter every day. In Experiment 1, listeners of all ages were able …

Playful Aggression And The Situational Contexts That Affect Perceptions, Jennifer Hart

UNLV Theses, Dissertations, Professional Papers, and Capstones

Play is considered a fundamental tool for early childhood education practices as it provides numerous developmental benefits for young children. However, not all play is viewed by children, parents, and early childhood educators the same, especially playful aggression. For example, rough-and-tumble play, risky play, superhero play, “bad guy” play, active pretend play, play fighting, big body play, war play, gun play, and physically active and imaginative play are types of playful aggression that benefits young children’s development; but are often viewed negatively by the adults who observe it. The contextual factors that influence the development of these conflicting perceptions—the motivation …

Assessing The Effect Of Race Saliency In Measures Of Children’S Implicit Bias, Veronica A. Glover

UNLV Theses, Dissertations, Professional Papers, and Capstones

The main goal of this study was to determine if race saliency affected responses on implicit measures of racial bias. Including racial labels in measures assessing implicit bias, particularly when presenting two racial groups vs. just one group, may inadvertently cue children that race is an important grouping variable and, in turn, increase the bias they display. We investigated 8- and 13-year old children’s performance on the affective priming task (APT), which does not use labels; the single category implicit association test (SCIAT) with Black faces and the SCIAT with White faces, each of which includes only one racial label; …

Parental Discussions About Sexual Risk With African American Sons: The Role Of Religiosity., Wadiya A. Udell, Geri R. Donenberg

Journal of Health Disparities Research and Practice

The current study investigated the relationship between parental religiosity (i.e., parent church attendance), and frequency of parent-youth communication about sexual risk (i.e., discussion about sex, and discussion about condom use) with African American boys. Participants were 65 parents of African American boys between the ages of 11 and 17 years. Results indicated no relationship between age and parent-son discussion about sexual risk. However, parental religiosity was negatively associated with frequency of communication with sons about sex and condom use. Parents who attended church more frequently reported fewer discussions about sex and condom use than parents who attended church less frequently. …

What's Age Got To Do With It? Examining How The Age Of Stimulus Faces Affects Children's Implicit Racial Bias, Erica Cheree Noles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Discrepant results regarding the emergence of children's implicit racial bias suggest additional research is needed to understand the developmental timeline of racial bias. Investigations using established explicit racial bias measures and the implicit association task with children demonstrate racial bias in young children (Aboud, 1988; Baron & Banjai, 2006). These findings do not corroborate the only known developmental use of the affective priming task (APT) to measure racial bias, which suggests implicit racial bias does not emerge until adolescence (Degner & Wentura, 2010). Variations in the task demands, the types of stimuli used to represent the construct of race, and …

Identity Status: The Impact On Academic Performance, Milan Jelenic

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this mixed methods study was to understand how environmental factors contributed to identity achievement with potentially positive effects on academic performance for fifth grade students. Early adolescents have not been studied partly because of the predominant acceptance of Erikson's (1968) theory of identity development. Four questions guiding the study were (a) whether adolescents acquired an Achieved identity status earlier than previous research has suggested, (b) if environmental issues such as familial obligations expedited identity achievement, (c) if identity status impacted academic performance, and (d) what was the impact of an Achieved identity on academic performance. Participants were …

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Exercise Differences, Karissa Dold

Calvert Undergraduate Research Awards

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …

Untangling Cultural Differences In Behavioral, Physiological, And Psychological Symptoms Of Dementia And Alzheimer’S Disease, John S. Avant

Calvert Undergraduate Research Awards

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; 4^th ed. Revised; American Psychiatric Association) and (BPSD) there are many behavioral, physiological, and psychological issues that have been correlated with the progression of the Alzheimer’s disease and other dementias. Examples of these issues include; emotional regulation problems, variations in eating behavior, and an advancing decline in memory. Though certain symptoms of the disease seem to be widely universal, current literature shows that a number of disparities do exist. There are several differences between and within populations suffering from Alzheimer’s disease and dementia that are influenced by various …

The Effect Of Experience On Infants’ Visual Preferences, Jennifer Bolick, Jennifer L. Rennels

McNair Poster Presentations

Research has shown that 3 to 4-month-olds with female primary caregivers show visual preferences for female relative to male faces (Quinn, Yahr, Kuhn, Slater, & Pascalis, 2002). Facial experience is likely an important influence on these preferences. From birth, infants’ experiences guide face processing skills. This processing ability influences the development of efficient face recognition later in life. The following study investigated (1) How visual pref­erences are influenced by real world experience with males and females, and (2) How experi­ence affects older infants’ visual preferences (i.e., 10-month-olds).

Do Toddlers Exhibit Same-Sex Preferences For Adult Facial Stimuli?, Andrea Jane Kayl

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the first year, infants exhibit visual preferences for female relative to male faces (Quinn, Yahr, Kuhn, Slater, & Pascalis, 2002). These visual preferences may reflect an adaptive behavior resulting from infants' greater experience with females during social interactions, particularly caregiving (McArthur & Baron, 1983; Rennels & Davis, 2008). As children learn they belong to a particular sex during toddlerhood, they become more active seekers of social knowledge and may begin to seek out members of that sex as models for determining appropriate activities and behaviors (Baldwin & Moses, 1996; Martin, Ruble, & Szkrybalo, 2002). The purpose of this investigation …

Problem Solving Interventions: Impact On Young Children With Developmental Disabilities, Lindsay Ann Diamond

UNLV Theses, Dissertations, Professional Papers, and Capstones

Problem-solving skills are imperative to a child's growth and success across multiple environments, including general and special education. Problem solving is comprised of: (a) attention to the critical aspects of a problem, (b) generation of solution(s) to solve the problem, (c) application of a solution(s) to the identified problem, and (d) evaluation of the consequences of the solution. Children with developmental disabilities may experience difficulty with the problem-solving process.

The purpose of this study was to determine an effective method to teach young children with developmental disabilities to problem solve. Specifically, this study compared two types of problem-solving instruction. The …

Evaluating A Social Skills Training Protocol In A Private Setting: Outcomes And Issues, Judi Davis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Society is dealing with a trend of aggressive and destructive behavior among children and adolescence. Children with social, emotional, and conduct problems are at high risk for academic failure, peer rejection, conduct disorder, school dropout, delinquency, and drug and alcohol problems (Webster-Stratton, Reid, & Stoollmiller, 2008). A high priority for the United States public health and crime prevention is the prevention of aggressive and delinquent behavior during childhood and adolescence (Taylor, Eddy, & Biglan 1999).

Social skills trainings aim to increase the performance of key social behaviors that are important for children to succeed in social situations. Solutions may be …

Playing With Fire Or Arson? Identifying Predictors Of Juvenile Firesetting Behavior, Mary Ellen Britt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Firesetting is a complex behavior that spans a wide range of developmental stages in childhood and adolescence and involves varying motivations and intents. A better understanding of this destructive behavior is critical to developing strategies to control its devastating effects. The purpose of this research project was to identify potential predictors of juvenile firesetting behavior by studying youth who were enrolled in a regional firesetting intervention program. Data collected from firesetting assessment instruments completed by parents or guardians of program participants were examined. In the analyses, special emphasis was placed on evaluating associations between juvenile firesetting behavior and the socioeconomic …

How Experience Influences Infants’ Recognition Of Male And Female Faces, Jennifer L. Rennels, Veronica A. Glover, Andrew J. Cummings, Andrea J. Kayl, Mateusz Orlewicz, Roanne J. Tiongson, Brooke Ditzler

Festival of Communities: UG Symposium (Posters)

Young infants with female primary caregivers are able to differentiate familiar female faces from novel female faces but not male faces. Experience processing faces may be important for being able to discriminate among similar-looking faces. Subsequently, increasing infants’ experience with less familiar faces should improve their ability to differentiate those types of faces. This study examined if infants’ experience with faces affected their recognition of new faces. Prior to testing, 2-3 month old infants were assigned to one of three conditions: a male video, a female video, and no video condition. Infants were familiarized to both male and female faces …

Verbal Cues: Producing The Same Results In Stereotype Threat Research?, Tarryn E. Mcghie

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined the notion that stereotype threat experiments can be influenced through linguistic manipulation. The cueing of a phrase (whether stereotypical or non-stereotypical) can produce performance differences between groups, rather than cueing of a stereotype, as used in previous research. Participants (n=95) mostly Caucasian females (68%) ranging in age from 18-45 (M=22.7). The design involved three groups and participants were randomly assigned in order to control for consequential affects. The control group received no verbal cues. The stereotypical group received a stereotypical cue (i.e. men tend to do better on this test than women). The counter-stereotypical group received a …

Contemporary Children’S Literature Recommendations For Working With Preadolescent Children Of Divorce, P. S. Mcmillen, Dale-Elizabeth Pehrsson

Library Faculty Publications

Bibliotherapy, defined most basically, is helping with books (Hynes & Hynes-Berry, 1994). Derived from the Greek words meaning book and therapy, bibliotherapy goals fall usefully into two categories. Clinical bibliotherapy, using books to facilitate specified therapeutic goals with those experiencing significant emotional or behavioral problems, involves trained health and mental health professionals such as psychologists, counselors, psychiatric nurses, or social workers. Developmental bibliotherapy, using books to address situational, transitional, and normal developmental issues, can be implemented by others, like educators or librarians, who work in helping roles. Books provide solace, reassurance, and even escape; they also provide new ideas for …

Inferring Rules From Sound: The Role Of Domain-Specific Knowledge In Speech And Music Perception, Aaronell Shaila Matta

UNLV Theses, Dissertations, Professional Papers, and Capstones

Speech and music are two forms of complex auditory structure that play fundamental roles in everyday human experience and require certain basic perceptual and cognitive abilities. Nevertheless, when attempting to infer patterns from sequential auditory input, human listeners may use the same information differently depending on whether a sound is heard in a linguistic vs. musical context. The goal of these studies was to examine the role of domain-specific knowledge in auditory pattern perception. Specifically, the study examined the inference of "rules" in novel sound sequences that contained patterns of spectral structure (speech or instrument timbre) and fundamental frequency (pitch). …

Cluster Analysis Of The Tomal Standardization Sample, Nicholas Shizuo Thaler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Children experience natural cognitive changes as they grow older, with more rapid memory development when they are younger. The purpose of the present study was to investigate the expected normal variation in youth using the Test of Memory and Learning (TOMAL; Reynolds & Bigler, 1994). The TOMAL is a broad-band verbal and nonverbal memory battery that has been standardized on youth aged 5-19, providing a good source of information on memory development in healthy children. Cluster analysis analyzed 1121 children selected from the TOMAL standardization sample and identified homogeneous profile subtypes of memory and learning. In addition, three age ranges …

Processes Of Disposition Development In K--5 Teachers, Deborah A. Obara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Educators concur that teacher competency requires more than teaching knowledge and skills; competency requires appropriate professional dispositions. The development of professional dispositions is an expected outcome of teacher education programs. Since 2002, program accreditation has been contingent on documentation that prospective teachers have met national standards for dispositions. The body of educational research on disposition assessment has been growing. Research on disposition learning and development, however, has been impeded by the prevailing conceptualization of dispositions as fixed traits resistant to change. The present study conceptualized dispositions as malleable constructs within a theoretical framework that synthesized a cognitive model of thinking …

Midlife Career Change And Women: A Phenomenological Examination Of The Process Of Change, Terry Ann Bahr

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this phenomenological study was to examine how fourteen women between the ages of thirty-five and fifty years old experienced the essence of making a midlife career change. Of further interest were the unique dimensions of each participant in their experience of this internal process of change. This study was an exploratory and inductive search for common themes and differences that these women shared throughout their experience of making a midlife career change.

Semi-structured interviews were conducted and thematic analysis was made by the construction of profile narratives for each participant. Five emerging themes were extracted from the …
