Multiple Approaches To Examining Gender Norms In Romantic Relationships, Carrie Underwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

Romantic relationships are essential to the human experience, and gender stereotypes are so ingrained they can be automatic. In this dissertation, I address three empirical questions through both quantitative and qualitative research methods, all of which contribute to the growing body of literature on gender norms and romantic relationships. In Chapter 2, I present a mixed-methods study that examines how heterosexual men reason about benevolent sexism. Results revealed themes of equality in the workplace and men’s roles as providers. In Chapter 4 I implemented a two-study research design to understand how heterosexual women and men reason about troubled romantic relationships. …

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 …

The Relation Between Positive Stereotypes, Negative Stereotypes, And Discriminatory Behavior Toward Hispanic And White Populations, Aileen Ynez Lovitt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research examining positive stereotypes has suggested a possible connection between positive stereotype endorsement and prejudice. This literature, however, has not investigated the relation between positive and negative stereotypes endorsement. Additionally, the combined impact of positive and negative stereotype endorsement predicting prejudice or discrimination has not been considered. Two studies were conducted to address the limitations in past research and gain a better understanding of positive stereotypes relating to behaviors toward out-group racial groups using Hispanic and White participants. Positive stereotypes endorsement was hypothesized to be positively associated with negative stereotype endorsement and was expected to increase the predicted power of …

Consequences Of Math Anxiety And Stereotype Threat: An Intersectional Perspective, Jennifer E. John Buck

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with science, technology, engineering, and math (STEM) skills are highly valued for their contribution to the U.S. workforce and society. However, women and some people of color enter STEM fields at lesser rates than do White men. Math anxiety and stereotype threat have been found to cause math performance decrements for women and some people of color. Presently, it is not clear how math anxiety and stereotype threat might work together to dually influence math performance and subsequent STEM participation. The current study focuses on a diverse sample of 295 undergraduate students who were randomly assigned to one of …

How Instruction, Math Anxiety, And Math Achievement Affect Learning A Novel Math Task: Evidence For Better Instruction, Amy Jane Mcauley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary goal of this paper is to test how math anxiety, achievement, and instruction affect learning a novel math task. Currently, most research measures achievement and math anxiety on previously learned tasks. A two-part study was proposed to measure the effects of math anxiety on learning modular arithmetic (MA), a novel math task that involves subtraction and division. Participants of varying degrees of anxiety and achievement were randomly assigned to either a specific or vague instruction condition. Participants were either taught how to solve the task or given minimal information about how to solve the task. Before moving on, …

Why Musical Groove Makes Us Move: An Electroencephalographic Investigation, Samantha Reina O'Connell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Moving to the groove of the music is a phenomenal and universal human behavior. Common characteristics to most dance music include a salient beat, rhythmic complexity, and a dynamic musical structure. What is unknown, however, is why music has the power to promote physical movement. Musical rhythm and motor processing are tightly linked activating brain areas important for motor preparation and execution. While studies demonstrate that the motor system is active during beat processing, it is still unclear how musical groove, a beat-influenced quality to music that makes us want to move, can engage these motor areas. Here, I performed …

The Effects Of Physical Attractiveness In The Health Care Industry, Richard Shane Westfall

UNLV Theses, Dissertations, Professional Papers, and Capstones

Physical appearance has a far-reaching influence on a variety of human interactions, yet the effects on one domain has been largely ignored. This dissertation examines the potential effect of physical attractiveness on health care quality. Theoretical explanations for the development of both prejudice and stereotypes are presented, with a focus on the development and effects of attractiveness-based stereotypes. Several studies have found that workers in the medical field are susceptible to the same biases as the general public and that these are associated with lower health care quality for those more marginalized by society. Therefore, two studies were conducted to …

Subjective Beat Perception In Musical Rhythms In Adult Listeners, Karli M. Nave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Synchronization to rhythmic stimuli is an everyday experience, whether it is exercising to the beat of music, dancing salsa, or rocking a baby to sleep. Commonly, humans synchronize their movements with the frequency of the beat (a quasi-isochronous pattern of prominent time points). Previous research has shown that the intended beat periodicity of a rhythmic stimulus can be observed in periodic neural activity; however, the extent to which this reflects robust perception of musical rhythm versus purely stimulus-driven activity is unknown. In Experiment 1 and 2, I investigated how long listeners can maintain a percept of the beat once the …

Associations Among Benevolent Sexism, Relationship-Contingent Self-Esteem, And Relationship Maintenance Strategies In Heterosexual Women, Carrie Underwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

Past research shows that heterosexual women who endorse benevolent sexism (a sex-role attitude) tend to be highly invested in romantic relationships (Lee, Fiske, Glick, & Chen, 2010). Consequently, they may be more likely than other women to remain in relationships that are troubled. The current study aimed to shed light on this possibility by examining whether benevolent sexism was associated with the relationship maintenance strategies that women use in troubled relationships. I presented women with a scenario of a troubled relationship and manipulated the type of sexism the male partner in the scenario endorsed. Repeated measures ANCOVA revealed that women …

The Psychophysiological Correlates Of Personality, Trauma, Posttraumatic Stress Disorder And Social Support, Meghan E. Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Theories considering the etiology of psychopathy suggest that trauma exposure, specifically childhood maltreatment and sexual abuse, is related to the development of callous-unemotional traits in children and adolescents, which are precursors to psychopathic traits in adulthood. Furthermore, posttraumatic stress disorder has an opposite relationship with many of the emotional and behavioral components of the two-factor model of psychopathy. Specifically, PTSD is positively associated to IA and traits associated with it and negatively associated with FD. Thus, this study sought to expand upon the current theories of a trauma-based etiology of psychopathy by investigating the relationship between trauma, PTSD, and psychopathic …

The Relationship Between Mood And Implicit Learning, Kathleen Larson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigates whether a person’s current mood state influences their ability to learn implicitly. Implicit learning refers to learning about regularities in the environment without having conscious access to the information (e.g., Reber, 1967). According to the affect-as-information hypothesis, a positive mood increases global processing of incoming information and negative mood leads to local processing (e.g., Clore & Storbeck, 2006); however, most previous studies that investigated mood and cognition have focused on more explicit types of learning and decision making, but few have examined implicit processes. Thus, the current experiments examined how varying levels of mood and arousal affect …

Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Mandy Walsh Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examined the effects of sex and type of partner infidelity, including both physical (i.e., sexually involved with another person) and emotional (i.e., emotionally involved with another person) infidelity, on mate abandonment behaviors. Previous research has demonstrated sex differences in emotional responses to infidelity, where men react more negatively to physical infidelity and women react more negatively to emotional infidelity. While various studies have investigated perceived behavioral reactions using imagined scenarios, this study expands current research by utilizing actual retrospective reports. It was hypothesized that males would engage in significantly more mate abandonment behaviors after experiencing a physical infidelity, …

Inner Experience And Self-Ratings Of Inner Speaking, Jason Michael Kelsey

UNLV Theses, Dissertations, Professional Papers, and Capstones

Questionnaires are often used as measures of inner experience. This study questions the adequacy of such measures, using inner speech as an example. We compared two questionnaire measures of inner speaking to each other and to inner experience as apprehended by Descriptive Experience Sampling (DES, a naturalistic, high fidelity method of exploring inner experience). Undergraduate volunteers (N = 260) took two questionnaires designed to measure inner speaking: the Self-Talk Scale (STS) and the Nevada Inner Experience Questionnaire (NIEQ). A subset of these (N = 16) participated in DES to investigate their inner speaking with fidelity. Scores on the NIEQ and …

Implicit Theories Of Intelligence And Learning A Novel Mathematics Task, Nathan Oehme Rudig

UNLV Theses, Dissertations, Professional Papers, and Capstones

The social-cognitive model of motivation states that students adopt a theory of the nature of intelligence that guides their goals in academia and their responses to academic setbacks. Students who believe intelligence is an unchanging entity within them are more likely to adopt goals to display high ability, hide low ability, and respond helplessly to failed schoolwork. Conversely, a student who believes intelligence is a measure of effort and persistence will be motivated to gather knowledge and acquire new skills. The current study investigated the role theories of intelligence play in the field of mathematics understanding. In two experiments, participants …

The Role Of Music-Specific Representations When Processing Speech: Using A Musical Illusion To Elucidate Domain-Specific And -General Processes, Christina M. Vanden Bosch Der Nederlanden

UNLV Theses, Dissertations, Professional Papers, and Capstones

When listening to music and language sounds, it is unclear whether adults recruit domain-specific or domain-general mechanisms to make sense of incoming sounds. Unique acoustic characteristics such as a greater reliance on rapid temporal transitions in speech relative to song may introduce misleading interpretations concerning shared and overlapping processes in the brain. By using a stimulus that is both ecologically valid and can be perceived as speech or song depending on context, the contribution of low- and high-level mechanisms may be teased apart. The stimuli employed in all experiments are auditory illusions from speech to song reported by Deutsch et …

Characteristics Of Subjects Who Avoid Activities And Participation Due To A Fear Of Falling In Parkinson’S Disease, Russell Gourlie, Spencer Sorensen, Rithea Vong

UNLV Theses, Dissertations, Professional Papers, and Capstones

Subjects: A total of 24 subjects (5 females, 19 males; mean age= 72.2, SD=9.1) participated in this study.

Methods: A cross-sectional design was used to identify descriptive characteristics of subjects with PD associated with moderate/high levels of fear avoidance behavior (MHA) or low levels of fear avoidance (LA) as measured by the Fear of Falling Avoidance-Behavior …

Emotional And Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Alyson Kay Baker

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the effect of sex on how people react, emotionally and behaviorally, to different types of partner infidelity. We expected to replicate previous findings that men experience more jealousy in reaction to their partner's sexual infidelity, and women experience more jealousy in reaction to their partners' emotional infidelity. We hypothesized that sex will affect behavioral reactions to infidelity as well. Specifically, we expected men to respond to sexual infidelity by terminating the relationship and to emotional infidelity by employing mate-guarding behaviors to prevent further infidelity. We hypothesized women would display the opposite pattern, leaving a relationship in …

Assessing The Conceptual Equivalence Of Measure Of Suppression In Culturally Diverse Samples, Amanda Louise Haboush

UNLV Theses, Dissertations, Professional Papers, and Capstones

In Western populations, some emotion regulation strategies have been associated with positive interpersonal abilities and mental health outcomes, while others, such as suppression, have been associated with negative physical and mental health outcomes (e.g., Eisenberg et al., 1997; Esterling, Antoni, Kumar, & Schneiderman, 1993; Gross & Muñoz, 1995; Kovacs, Joormann, & Gotlib, 2008). However, Butler, Lee, & Gross (2007) have demonstrated that the negative effects of suppression do not occur in some Eastern cultures. This inconsistency may be due to a lack of measurement equivalence across cultures.

To examine suppression in other cultural groups, researchers often adapt existing measures that …

Examining The Testing Effect Using The Dual-Process Signal Detection Model, Nicole Jessica Bies-Hernandez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taking a test can lead to enhanced long-term retention compared to not practicing the information or simply restudying, a finding known as the testing effect (Roediger, Agarwal, Kang, & Marsh, 2010). The current study examined whether the dual-process signal detection (DPSD) model (Yonelinas, 1994) offers an approach for investigating the testing effect across two experiments. Experiment 1 investigated if the DPSD model could be used to examine the testing effect, and it also examined a factor (i.e., the number of practice sessions) that influences the magnitude of the testing effect. Experiment 2 investigated whether making the final test dependent on …
