The Optimum Performance Program In Sports - Youth: A Case Study, Karolyne Bastos Stucki Dec 2021

The Optimum Performance Program In Sports - Youth: A Case Study, Karolyne Bastos Stucki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ethnically and racially diverse youth athletes underutilize mental health services, resulting in social and economic costs to society (Gudiño et al., 2008; Snowden & Yamada, 2005). Almost half of all children and adolescents participate in sport, and sport participation is especially common in youth from ethnically and racially diverse neighborhoods (Holt, 2008; NSCH, 2017). Therefore, sport may be an effective strategy to permit diverse youth to receive mental health services. The current case study examines The Optimum Performance Program in Sports (TOPPS; a sport-specific family behavior therapy) in an Asian American youth athlete evidencing Social Anxiety Disorder (DSM-5). A within …


How Can We Reduce Racism? A Mixed Method Study Of Factors That Influence Attitudes Towards Social Change, Kindy Insouvanh Dec 2021

How Can We Reduce Racism? A Mixed Method Study Of Factors That Influence Attitudes Towards Social Change, Kindy Insouvanh

UNLV Theses, Dissertations, Professional Papers, and Capstones

The resurgence of social movements such as Black Lives Matter has provoked public discourse about racial inequality and efforts towards social change. The current study sought to better understand how young adults reason about racism reduction with a focus on racial allyship and collective action. The present study used mixed methods to identify strategies young adults believe different racial groups could do to reduce racism and investigate the influence that individual factors have on reasoning about social change. Here, I present emergent themes to describe racism reduction strategies from a large and racially diverse sample of undergraduate students (N= 428). …


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 Dec 2021

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 …


Are Gaming And Gambling Disorders Related? Examining The Roles Of Money, Relative Deprivation, And Upward Mobility, Anthony J. King Aug 2021

Are Gaming And Gambling Disorders Related? Examining The Roles Of Money, Relative Deprivation, And Upward Mobility, Anthony J. King

UNLV Theses, Dissertations, Professional Papers, and Capstones

Few studies have examined the financial motives and risks involved in modern video games, as well as the psychosocial factors contributing to this type of gaming involvement. Previous research on gambling has shown financial motives alone to be a major risk factor for the development of gambling disorder, with higher levels of personal relative deprivation (PRD) identified as a main contributor to this relationship. Therefore, the present study investigated whether this association applied to US adult video gamers, and if it would predict their problematic gaming behaviors. We hypothesized PRD and gaming disorder severity would have a positive association, with …


Exploring The Relation Between Musical And Dance Sophistication And Musical Groove Perception, Samantha R. O'Connell Aug 2021

Exploring The Relation Between Musical And Dance Sophistication And Musical Groove Perception, Samantha R. O'Connell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Listening to groovy music is an enjoyable experience and a ubiquitous human behavior in some cultures. Specifically, many listeners agree that high-groove songs are enjoyable, familiar, and likable compared to low-groove songs. While the pleasurable and dance-inducing effects of musical groove listening seem omnipresent, what is less known is how subjective feelings towards music, individual musical or dance experiences, or more objective musical perception abilities are correlated with the way we hear music with groove. Therefore, the present online study aimed to evaluate how musical and dance sophistication relates to musical groove perception. One-hundred and twenty-four participants completed an online …


Measures And Conceptualizations Of Symptoms In Schizophrenia, Nina B. Paul Aug 2021

Measures And Conceptualizations Of Symptoms In Schizophrenia, Nina B. Paul

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia presents as a heterogenous disorder characterized by diverse expression of symptoms between individuals. Thus, clinicians and researchers rely on comprehensive symptom measures for diagnosis and treatment. This dissertation investigated two symptom measures, the Positive and Negative Syndrome Scale (PANSS; Kay, Fiszbein, & Opler, 1987), a commonly used scale that assesses a broad range of symptoms of schizophrenia, as well as the Brief Negative Symptom Scale (BNSS; Kirkpatrick et al., 2011; Strauss et al., 2012), a novel scale that focuses on the assessment of five negative symptom domains (i.e., anhedonia, asociality, avolition, blunted affect, and alogia). The first study of …


Presumed Illegal Microaggressive Experience (Prime): A Microaggression Targeting Latinx Individuals, Aldo M. Barrita Aug 2021

Presumed Illegal Microaggressive Experience (Prime): A Microaggression Targeting Latinx Individuals, Aldo M. Barrita

UNLV Theses, Dissertations, Professional Papers, and Capstones

In the US, people of color (PoC) are consistently the targets of microaggressions, a form of everyday racism (Pierce et al., 1977; Chavez, 2013) manifested in brief, commonplace, daily slights and indignities (Sue et al., 2007). After the 2016 elections, Americans immediately reported an increase in social tensions across racial groups (Pew Research, 2017). Latinxs, in particular, reported a steep rise in experiences with racial and ethnic discrimination (Gomez & Perez Huber, 2019; Jones et al., 2019), particularly around the context of immigration status (Santos et al., 2021). No previous research, however, has explored the experience of assumed illegality based …


It’S Not You, It’S Me: Measuring Erotic Self–Focus, Evan Fertel Aug 2021

It’S Not You, It’S Me: Measuring Erotic Self–Focus, Evan Fertel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research suggests the presence of a non-relational aspect of women’s sexuality wherein a focus on oneself may be linked to elevations in sexual desire/arousal. Some theorists have even asserted that women may be, in some ways, their own sexual objects. Building on a previous exploration of what is now termed Erotic Self-Focus (ESF; Fertel, 2015), the present study developed a refined measure of ESF to further assess the validity and nature of this new construct. An exploratory factor analysis revealed four factors: Arousal to Own Body, Self/Own-Gender Focus vs. Partner/Other-Gender Focus, Self-Focused Arousal – Physical, Self-Focused Arousal – Mental. Although …


Defining Problematic School Absenteeism: Identifying Youth At Risk, Mirae J. Fornander Aug 2021

Defining Problematic School Absenteeism: Identifying Youth At Risk, Mirae J. Fornander

UNLV Theses, Dissertations, Professional Papers, and Capstones

Study 1: School attendance is an important foundational competency for children and adolescents, and school absenteeism has been linked to myriad short- and long-term negative consequences, even into adulthood. Many efforts have been made to conceptualize and address this population across various categories and dimensions of functioning and across multiple disciplines, resulting in both a rich literature base and a splintered view regarding this population. This article (Part 1 of 2) reviews and critiques key categorical and dimensional approaches to conceptualizing school attendance and school absenteeism, with an eye toward reconciling these approaches (Part 2 of 2) to develop a …


Attention Bias In Irritability: A Social Information Processing Perspective, Breanna Garcia Aug 2021

Attention Bias In Irritability: A Social Information Processing Perspective, Breanna Garcia

UNLV Theses, Dissertations, Professional Papers, and Capstones

Social information processing (SIP) theory suggests a framework for understanding how individuals make sense of their world—from the cognitive tasks of perception and problem solving to the emotional tasks of integrating this information with one’s goals, motivational state, and arousal regulation. This framework has been integral for better understanding the etiology behind certain psychopathologies (such as depression or disruptive behavior disorders) as it is thought that bias early in attentional processes may have trickle down effects on later processing and decision making (Dodge, 1993). It is known that the attention biases early in the SIP model (e.g., encoding biases) differ …


Is Pristine Inner Experience Linked To Biology? An Examination Of Experience Across The Menstrual Cycle Among Women With Premenstrual Distress, Alek E. Krumm Aug 2021

Is Pristine Inner Experience Linked To Biology? An Examination Of Experience Across The Menstrual Cycle Among Women With Premenstrual Distress, Alek E. Krumm

UNLV Theses, Dissertations, Professional Papers, and Capstones

The link between mind and biology is intuitively known: We notice changes in our mood and behavior when hungry, in pain, or under the influence of substances. Yet, the specifics of this link—for example, how changes in biology affect directly apprehended conscious experience— are not well known. The present study was an exploratory attempt toward filling that gap by using a state-of-the-art, beeper-driven method for exploring directly apprehended conscious experience (Descriptive Experience Sampling; DES) across one of the most predictable and wellknown biological cycles: menstruation. We screened approximately 300 college women to identify those who reported clinically significant symptoms of …


Investigation Of Algorithms To Assess Validity Of Wearable Technology During Field Testing, Brenna Barrios May 2021

Investigation Of Algorithms To Assess Validity Of Wearable Technology During Field Testing, Brenna Barrios

UNLV Theses, Dissertations, Professional Papers, and Capstones

Wearable technology is an emerging fitness trend where the technology which supports it lacks validity verification. Furthermore, heart rate validity of these devices vary greatly when observed in laboratory settings vs. field testing. Secondarily, Consumer Technology Association guidelines require a minimum five minute trial for wearable testing. This study examined heart rate data of previously tested wearable devices (Garmin Fenix 5, Jabra Elite Sport, Motiv Ring, Scosche Rhythm+) in an outdoor setting to further understand their performance, and to examine the relationship of the five minute regulation. Two separate algorithms were applied to the original data set, the first shortened …


Controlled Evaluation Of A Family-Based Optimization Intervention Implemented Through Video-Conferencing To Address Adhd And Oppositional Defiant Disorder In An Adolescent Athlete, Dereck Davy Phrathep May 2021

Controlled Evaluation Of A Family-Based Optimization Intervention Implemented Through Video-Conferencing To Address Adhd And Oppositional Defiant Disorder In An Adolescent Athlete, Dereck Davy Phrathep

UNLV Theses, Dissertations, Professional Papers, and Capstones

Adolescent athletes with Attention Deficit Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) experience unique challenges that impact their sport performance, such as making errors due to poor concentration and adverse relationships with referees due to poor anger management. Pharmacological treatments have shown to be successful in treating ADHD comorbid with ODD. However, there are negative consequences for pharmacological treatments for adolescent athletes (e.g., banned by sports organizations). Well-established behavioral interventions for ADHD and ODD in non-athlete populations have included family-based, cognitive-behavioral approaches. However, none of these interventions have been evaluated in competitive adolescent athletes. The current case trial involved …


Bystanders’ Willingness To Report Crimes And Cooperate With Legal Authorities: The Role Of Individual And Contextual Differences, Matthew P. West May 2021

Bystanders’ Willingness To Report Crimes And Cooperate With Legal Authorities: The Role Of Individual And Contextual Differences, Matthew P. West

UNLV Theses, Dissertations, Professional Papers, and Capstones

Studies and victimization surveys suggest that many, if not most, crimes are not reported to legal authorities. The overarching aim of this project was to examine the roles of individual and contextual differences in bystanders’ willingness to report crimes to, and cooperate with, legal authorities. A sample of 1,434 adults in the U.S. completed a survey in which they read and responded to crime vignettes and responded to items theoretically measuring individual differences in legal socialization, perceived legitimacy, the need for cognitive closure, right-wing authoritarianism, social dominance orientation, and the general willingness to cooperate. Bystanders’ relationship to the victim, relationship …


Gambling Behaviors Among Vip Hosts In Macao, Tiange Xu May 2021

Gambling Behaviors Among Vip Hosts In Macao, Tiange Xu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many studies have shown that casino employees are at-risk gamblers, but limited research on this topic has been conducted in Asia. Given the unique gambling setting of Macao, it would be meaningful to investigate the gambling behaviors among VIP Hosts, who play an important role in the gaming market. Specifically, the present study examined the relationship between problem gambling, cognitive distortions, and potential risk and protective factors. The author used a snowball technique to recruit participants and an online survey to collect data. A total of 41 responses were included in the data analysis. The results showed that VIP Hosts …


Acoustic And Semantic Processing Of Speech And Non-Speech Sounds In Children With Autism Spectrum Disorders, Breanne D. Yerkes May 2021

Acoustic And Semantic Processing Of Speech And Non-Speech Sounds In Children With Autism Spectrum Disorders, Breanne D. Yerkes

UNLV Theses, Dissertations, Professional Papers, and Capstones

The processing of semantically meaningful non-speech and speech sounds requires the use of acoustic and higher-order information, such as categorical knowledge and semantic context. Individuals with an autism spectrum disorder (ASD) have been theorized to show enhanced processing of acoustic features and impaired processing of contextual information. The current study investigated how children with and without ASD use acoustic and semantic information during an auditory change detection task and semantic context during a speech-in-noise task. Furthermore, relationships among IQ, the presence of ASD symptoms and the use of acoustic and semantic information across the two tasks were examined among typically …


Development And Initial Validation Of The Veterans Educational Transition Scale (Vets): A Brief Scale To Predict Successful Transition Of Student Veterans To College, Lisa Beckman Dec 2020

Development And Initial Validation Of The Veterans Educational Transition Scale (Vets): A Brief Scale To Predict Successful Transition Of Student Veterans To College, Lisa Beckman

UNLV Theses, Dissertations, Professional Papers, and Capstones

The aim of this dissertation was to develop and validate a scale to assess factors that interfere with veterans’ successful transition from military life to the college environment. Student veterans are a unique population in the student body and often have unique challenges assimilating to the college environment, including difficulties making social connections, multiple life responsibilities, and unique mental health presentations. Currently, there is no measure to assess and identify transition challenges that student veterans may experience, and yet significantly more veterans are enrolling in college to take advantage of their post-9/11 GI bill benefits. This dissertation includes two studies. …


Validity And Diagnostic Accuracy Of An Adhd Symptom Rating Scale For Identifying Adults With Adhd, Stacy Jean Graves Dec 2020

Validity And Diagnostic Accuracy Of An Adhd Symptom Rating Scale For Identifying Adults With Adhd, Stacy Jean Graves

UNLV Theses, Dissertations, Professional Papers, and Capstones

Specific rating scales of ADHD symptomatology are often included in neuropsychological assessments evaluating adults diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). The Barkley Adult ADHD Rating Scale-IV (BAARS-IV) is a widely used symptom rating scale that includes four questionnaires: self-report current, self-report childhood, other-report current, and other-report childhood. In addition to ADHD symptoms, each of the forms include items that assess functional impact and developmental history of symptomatology. While similar symptom rating scales have been found to have high validity and diagnostic utility in children, it is unclear the extent to which the BAARS-IV shares substantial common variance with other …


Identifying School Climate Predictors Of School Absenteeism, Victoria Bacon Aug 2020

Identifying School Climate Predictors Of School Absenteeism, Victoria Bacon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attendance is a crucial component of the education system and may be addressed utilizing Multi-Tiered System of Supports (MTSS) models. To effectively utilize such models, clear demarcations between tiers must exist to classify students appropriately. Additionally, relevant risk and protective factors must be identified as targets for intervention and prevention efforts at each tier. Little research exists that identifies school climate factors, and other student-based contextual factors such as academic mindset and social emotional learning, that impact absenteeism. The present study aimed to identify suitable tier demarcations as well as school climate and student-based contextual factors relevant at each tier. …


Network Analysis Of Cognitive Symptom Domains In Alzheimer's Disease (Ad), Abigail Rose Baily Aug 2020

Network Analysis Of Cognitive Symptom Domains In Alzheimer's Disease (Ad), Abigail Rose Baily

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer’s Disease (AD) is a degenerative neurological disease process that results in cognitive and functional declines and ultimately results in death. The pattern and course of cognitive and functional decline has been well characterized in AD, however little is known about the interactions between the symptoms. Network Analysis is a recently developed mathematical approach of examining the interactions between symptoms, by exploring the covariance of symptoms. The current study utilized network analysis to examine the multivariate structural dependencies among cognitive domains known to be affected in Alzheimer’s disease. The sample consisted of 864 older adults (60-90 years old), selected from …


The Factor Structures Of Ability And Trait Emotional Intelligences Relative To General Intelligence And Personality, Nicholas Carfagno Aug 2020

The Factor Structures Of Ability And Trait Emotional Intelligences Relative To General Intelligence And Personality, Nicholas Carfagno

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotional Intelligence is a popular term used to describe one’s experience with their own emotions and awareness of others’. Although emotional intelligence is thought to be a helpful predictor of various variables such as work performance and wellbeing, there is disagreement within the field of the precise definition and method of measurement. The current study examines two of the most popular models of emotional intelligence, ability and trait models, to determine if they are the same construct or two different constructs that share a moniker. Additionally, both ability and trait emotional intelligences’ factor structures are examined through hierarchical and bifactor …


Functional Capacity Profiles In Bipolar Disorder And Schizophrenia, Ashley Sara Emami Aug 2020

Functional Capacity Profiles In Bipolar Disorder And Schizophrenia, Ashley Sara Emami

UNLV Theses, Dissertations, Professional Papers, and Capstones

Serious mental illnesses (SMIs) often have an onset early in life and go on to produce disability and functional impairment, which require ongoing supportive services and loss of productivity. Bipolar disorder (BD) and schizophrenia (SZ) are two of the most common SMIs. BD and SZ differ in their pattern of neurocognitive performance, which suggests differences in the severity of functional impairment between the illness groups. Within these psychiatric illness groups, subgroups may also be identified using cluster analysis. Evidence points to heterogeneity in functional outcomes in BD and SZ, yet very little research has assessed for subgroups based on functional …


Anxious And Oppositional Behavior Factors In A Community Sample Of Youth With Selective Mutism, Andrew Gerthoffer Aug 2020

Anxious And Oppositional Behavior Factors In A Community Sample Of Youth With Selective Mutism, Andrew Gerthoffer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Selective mutism (SM) is a childhood disorder characterized by a failure to speak in certain situations (e.g., school, social situations; APA, 2013). SM is best assessed using a comprehensive multimodal strategy (Dow et al., 1995; Krysanski, 2003; Viana et al., 2009; Wong, 2010), including parent reports of a child’s behavior. One commonly used parent report measure is the Child Behavior Checklist (CBCL; Achenbach & Rescorla, 2001). The purpose of the present study was to identify specific CBCL items that may help substantiate SM subtypes in children. The study used confirmatory factor analysis to determine whether a two-factor structure (anxious and …


Examination Of The Relationship Between Sport-Specific Thoughts And Emotions And Anxiety And Depression In College Athletes, Marina Elizabeth Harris Aug 2020

Examination Of The Relationship Between Sport-Specific Thoughts And Emotions And Anxiety And Depression In College Athletes, Marina Elizabeth Harris

UNLV Theses, Dissertations, Professional Papers, and Capstones

Depression and anxiety are prevalent mental health difficulties affecting student athletes, who notoriously reject mental health interventions that are not sport-relevant. This study will assist in understanding the extent to which sport-relevant thoughts and emotions impact depression and anxiety in collegiate athletes. Two-hundred and twenty-five NCAA athletes competing at the Division, I, II, or III level were administered the Sport Interference Checklist (SIC), Test of Performance Strategies (TOPS), Generalized Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire (PHQ-9). Results of correlational analyses revealed a significant relationship between SIC Dysfunctional Thinking (in training and competition) and anxiety (GAD-7) and depressive (PHQ-9) symptoms, …


Investigating The Inner Experience Of Individuals Attending Psychotherapy At A Community Mental Health Center, Stefanie A. Moynihan Aug 2020

Investigating The Inner Experience Of Individuals Attending Psychotherapy At A Community Mental Health Center, Stefanie A. Moynihan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although psychotherapy outcome studies sometimes use qualitative methods (e.g., interviews and traditional sampling methods), the majority of those studies rely mainly on quantitative methods (e.g., retrospective self-report progress-monitoring questionnaires), even when investigating clients’ experience of treatment. However, there are reasons to believe that both qualitative and quantitative methods are substantially flawed—both interviews and self-report questionnaires investigating experience can yield substantially inconsistent findings in comparison to careful, descriptive sampling-based methods such as Descriptive Experience Sampling (DES). To date, there are neither qualitative nor quantitative published studies that explore the everyday, natural inner experience of psychotherapy clients. The current study used DES, …


Addressing Disparities In Cross-Cultural Neuropsychological Assessment, Alicia Nuñez Aug 2020

Addressing Disparities In Cross-Cultural Neuropsychological Assessment, Alicia Nuñez

UNLV Theses, Dissertations, Professional Papers, and Capstones

There are existing disparities in Attention-Deficit/Hyperactivity Disorder (ADHD) assessment, diagnosis, and treatment among ethnic/racial minority children. Thus, greater empirical attention must be given to the neuropsychological assessment of Spanish-speaking children to address linguistic diversity and psychometric equivalence of commonly used measures, like the Wechsler Intelligence Scales for Children (WISC), across cultural groups. Therefore, this dissertation addressed the following aims: (I) examined the factor structure of the WISC–Fourth Edition Spanish (WISC-IV Spanish) in Hispanic children with ADHD, (II) evaluated the feasibility of developing short forms of the Spanish version of the WISC to expand the assessment toolbox for Spanish-speaking children with …


Memory And Stereotypes For Lesbian/Gay Characters, Amber Rose Williams Aug 2020

Memory And Stereotypes For Lesbian/Gay Characters, Amber Rose Williams

UNLV Theses, Dissertations, Professional Papers, and Capstones

Stereotype-consistency bias refers to the idea that people tend to remember stereotypical information about others better than non-stereotypical information (Fyock & Stangor, 1994). Limited research has examined how people may use stereotype-consistency bias when recalling information about LGBT characters in narratives (Bellezza & Bower, 1981; Clark & Woll, 1981; McGann & Goodwin, 2007; Snyder & Uranowitz, 1978). This line of research suggests that, instead of genuinely remembering stereotypical information better, participants tended to guess stereotypical answers to questions they do not know. In contrast to those studies, the experiment I conducted for this thesis suggests that heterosexual young adults tend …


The Prevalence And Predictors Of Complementary And Alternative Medicine (Cam) Use Among Racially/Ethnically Diverse College Students, Hermella Misiker Aug 2020

The Prevalence And Predictors Of Complementary And Alternative Medicine (Cam) Use Among Racially/Ethnically Diverse College Students, Hermella Misiker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: National data on complementary and alternative medicine (CAM) use, available through the National Health Interview Survey (NHIS), convey higher prevalence of CAM use among college students compared to the general U.S population. NHIS findings also highlight non-vitamin non- mineral (NVNM) products are the most widely used form of CAM in the U.S. The purpose of this study was to identify the socio-cognitive and demographic predictors of CAM and NVNM use among a racially/ethnically diverse college student body.

Methods: An online survey was used to collect data from 392 University of Nevada, Las Vegas (UNLV) undergraduate, graduate, and professional students. …


Musical Meter: Examining Hierarchical Temporal Perception In Complex Musical Stimuli Across Human Development, Sensory Modalities, And Expertise, Jessica Erin Nave-Blodgett Aug 2020

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 …


Eyewitness Recall And Identification Accuracy: Effects Of Stress In An Extreme Haunt And A Haunted House, William Blake Ridgway Aug 2020

Eyewitness Recall And Identification Accuracy: Effects Of Stress In An Extreme Haunt And A Haunted House, William Blake Ridgway

UNLV Theses, Dissertations, Professional Papers, and Capstones

The impact of stress on eyewitness recall and identification accuracy has been studied extensively but with somewhat inconsistent results. Understanding the effects of stress are important if they are to be generalized to victims or witnesses of real crimes. This study consisted of two experiments that used an extreme haunt and a haunted house to examine attendees’ ability to recall details of and identify actors encountered, as a function of state anxiety and in the context of Deffenbacher’s (1994) catastrophe model of memory performance under anxiety. The results showed that physiological (i.e., heart rate) and psychological (i.e., State Anxiety Inventory) …
