Navigating The Unknown: Understanding The Impact Of Mentorship For First-Generation Students In Stem, Shanika Roshanie Wickramarachchi

UNLV Theses, Dissertations, Professional Papers, and Capstones

First-generation students often encounter systemic barriers and inequities in academic pursuits related to science, technology, engineering, and math (STEM). Many institutions implement mentoring programs to mitigate these challenges; however, the effectiveness of STEM mentoring relationships for first-generation college students has been underexplored in the empirical literature. The current study centers the voices of first-generation college students to explore how mentors and institutions can better support their success through STEM mentoring relationships. In addition, this study examines how mentors’ generational status informs how they approach mentoring relationships with first-generation mentees. Participants included mentors and first-generation mentees in STEM research mentoring relationships …

The Speech-To-Song Illusion Across Development And The Effects Of High-Level Expectations, Rodica R. Constantine

UNLV Theses, Dissertations, Professional Papers, and Capstones

The typical listener can readily categorize auditory stimuli as either speech or song even though these structures share many acoustic similarities. These musical and linguistic categories may nevertheless take time to develop as children acquire language- and music-specific knowledge. In the Speech-to-Song (STS) illusion, multiple repetitions of a natural spoken utterance can give rise to a perceptual switch wherein the stimulus begins to sound song-like to the listener. While the STS illusion has been well-researched in adult listeners, it had yet to be investigated in children. In our study, we examined whether children experience the STS illusion by presenting participants …

Gender Biases: The Interaction Between Children And Voice Assistants, Trà Hương Bùi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Nowadays, children can access and interact with voice assistants (VAs) easily since the machines are more available in the family context. However, there is a gap in understanding how children conceptualize VAs when interacting with the machine. Specifically, this study aimed to examine whether children understand VAs as inanimate. Additionally, the study also compared how children and adults rate the VAs’ level of warmth and competence and the way they associate AI voices with feminine or masculine faces. Another goal was to explore how children and adults match the gender and competence/warmth of the VA with facial masculinity and femininity. …

Latina Maternal Anxiety And Early Child Development: A Scoping Review, Micaela Gigena

Undergraduate Research Symposium Posters

Latina mothers' mental health struggles, particularly anxiety, can significantly impact their children's development. In Latino culture, stigma and shame surrounding mental health discussions often prevent individuals from seeking help, which can exacerbate effects. This scoping review aims to examine currently available research on the impact of maternal anxiety on early child development in Latina populations across North America, South America, and the Caribbean. A literature search was performed to find relevant peer-reviewed and grey literature through five electronic databases. Out of 469 results, 33 relevant studies were identified for full-text screening. Data will be extracted to explore the association between …

Age, Gender, And Sexual Orientation And Their Effects On Online Dating Motivations, Jenna Leigh Mcpherson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Online dating and dating apps are becoming more common as a means to meet a romantic or sexual partner (e.g. Rosenfeld, Thomas, & Hausen, 2019). Previous literature on the motivations for why people use dating apps and how they differ among participants of varying age, gender, and sexual orientation has not allowed for comparisons across these groups, or shows conflicting findings. In order to consolidate existing literature and further explore the topic, I conducted both a meta-analysis and meta-synthesis. The meta-analysis demonstrated a gender difference in the motivation of casual sex, such that men scored higher than women. The meta-synthesis …

Musical Chills: The Effect Of Age And Musical Ability, Isabella Aceituno, Erin Hannon, Solena Mednicoff

Undergraduate Research Symposium Posters

Musical chills mark a peak emotional response to music, characterized by goosebumps, tingling sensations down the back, and raised hair on the skin. Previous research has connected musical chills to changes in music such as crescendos, the entrance of new voices or instruments, unexpected harmonies, or changes in acoustic features. Knowledge of musical structures, such as key and harmony, develop from infancy to adulthood. If children’s musical expectations change with age, so too might their emotional musical experiences.

Perceptual Learning Of Infants Across Domains, Melanie Garcia, Carolina A. Herrera, Ryan K. Perez, Rodica R. Constantine, Erin E. Hannon

Undergraduate Research Symposium Posters

Infancy is a unique developmental period in which there is rapid attunement of perceptual systems to specific environmental properties. Perceptual narrowing: By the end of the first year, infants become adept processors and develop expertise of familiar socially meaningful domains such as faces, language, and music leading to subsequent social and cognitive abilities. The mechanisms driving these perceptual changes remain debated, with contrasting accounts proposing experience-dependent or domain-general influences. Objective: This research aims to investigate whether perceptual narrowing in early development is primarily driven by domain-specific experiences or by domain-general factors such as brain maturation and information processing.

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 …

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 …

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 …

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 & Global Health Faculty Research

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 …

Use Of Behaviour Change Techniques By Direct Support Professionals To Support Healthy Lifestyle Behaviour For People With Moderate To Profound Intellectual Disabilities, Annelies Overwijk, Annette A.J. Van Der Putten, Cees P. Van Der Schans, Mariël Willems, Thessa I.M. Hilgenkamp, Aly Waninge

Physical Therapy Faculty Research

Background: Behaviour change techniques (BCTs) can be employed to support a healthy lifestyle for people with intellectual disabilities. The aim of this study is to determine whether and which BCTs are used by direct support professionals (DSPs) for supporting healthy lifestyle behaviour of people with moderate to profound intellectual disabilities. Method: Direct support professionals (n = 18) were observed in their daily work using audio-visual recordings. To code BCTs, the Coventry Aberdeen London Refined (CALO-RE-NL) taxonomy was employed. Results: Direct support professionals used 33 BCTs out of 42. The most used BCTs were as follows: ‘feedback on performance’, ‘instructions on …

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 …

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; …

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 …

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 …

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 …

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 …

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).

The Initial Development Of Child-Focused Interventions In The Treatment Of Maternal Substance Abuse And Child Neglect, Kendra Tracy

UNLV Theses, Dissertations, Professional Papers, and Capstones

This single case study focuses on the development and evaluation of child focused interventions for the treatment of child neglect and concurrent maternal substance abuse that were incorporated into Family Behavior Therapy (FBT). The participants were a mother referred by the Department of Family Services and her child. The child participated in three child focused interventions that were developed to decrease child behavior problems, increase support and communication, and prevent future neglect by strengthening the mother & child relationship. Although not a focus in this study, the mother participated in traditional FBT adult focused intervention components. The chief aim of …

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 …
