Constructed Response Formats And Their Effects On Minority-Majority Differences And Validity, Filip Lievens, Paul R. Sackett, Jeffrey Dahlke, Janneke Oostrom, Britt De Soete

Research Collection Lee Kong Chian School Of Business

The inflow of immigrants challenges organizations to consider alternative selection procedures that reduce potential minority (immigrants)-majority (natives) differences, while maintaining valid predictions of performance. To deal with this challenge, this paper proposes response format as a practically and theoretically relevant factor for situational judgment tests (SJTs). We examine a range of response format categories (from traditional multiple-choice formats to more innovative constructed response formats) and conceptually link these response formats to mechanisms underlying minority-majority differences. Two field experiments are conducted with SJTs. Study 1 (274 job seekers) contrasts minority-majority differences in scores on a multiple-choice versus a written constructed response …

The Impact Of Exposure To The Thin Ideal On Chocolate Cravings In U.S. -Born Women, Kathryn M. Helm

Psychology

Food cravings are experienced by a large proportion of the population and have a variety of negative implications- including overweight/ obesity, heart disease, and type 2 diabetes. Prior research has shown a lack of support for biological causes of craving. As such, we look to other factors such as culture, cognition, and sex, to explore why such factors have an influence on craving. The purpose of this study is to look at the impact of viewing thin ideal images on chocolate cravings in United States born women-including (but not restricted to) their reports of ambivalence towards chocolate. Participants were randomized …

Measuring Neural Time Series Data In A Sensory Deprivation Tank, Jackson Gregory, Tian Lan, Uri Maoz, Amir Raz

Student Scholar Symposium Abstracts and Posters

We are interested in studying the neurological and physiological effects of the float pod, also known as REST therapy, or sensory deprivation tank. Float pods rely on the concept of depriving most senses (from sound and light to temperature and proprioception) in a pool filled with buoyant salt water at body temperature. While float pods are most commonly used in spa environments, we intend to look at the potential benefits of floating under the empirical lens. In this study, we aim to measure neural activity using electroencephalography (EEG). We intend to look at the different levels of relaxation and the …

Gender Prescriptions And Stereotypes Surrounding Consensually Non-Monogamous Relationships, Carsyn Knebel, Gabi Siguenza, Meghan Dunn, Mary Kruk, Jes Matsick

Student Scholar Symposium Abstracts and Posters

Background

Sexuality is a domain in which stereotypes and expectations are particularly pronounced for women and men (Alexander & Fisher, 2003). In the current study, we examined people’s perceptions of whether women or men are more “biologically wired” for and likely to suggest engaging in swinging, open, and polyamorous relationships (known as consensual non-monogamy or CNM). Central to our analysis are comparisons by relationship style (single, engaged in monogamy, engaged in CNM).

Methods

Using online recruitment strategies (N = 1,020; 65% women; M = 34 years), we assessed gendered perceptions of CNM relationships among participants who were currently single (n …

A Study Of Beluga (Delphinapterus Leucas) Vocal Ontogeny, Audra Elizabeth Ames

Dissertations

There is a shortage of literature regarding beluga (Delphinapterus leucas) vocal ontogeny, as presently, there has only been one published study on the vocal development of beluga calves, despite the value of ontogenetic studies for our understanding of sound-centered species. Here I offer the second longitudinal study of beluga vocal development. Using a calibrated digital hydrophone with a sampling rate of 256 kHz, I studied the vocal progression of a male beluga calf in early life. From his first day, the calf produced broadband pulse trains with upper frequency limits extending past the study’s Nyquist frequency (128 kHz); …

Direct Behavior Observations And Teachers' Ratings Of Internalizing Problem Behaviors, Lauren R. Parker

Honors Theses

Systematic direct observation is a commonly used method in schools to compile data on students' behavior in a naturalistic setting. Internalizing problem behaviors, behaviors such as social withdrawal, somatic complaints, and anxiousness, can lead to adverse consequences and have not, to the researchers' knowledge, been systematically observed in a classroom setting. Additionally, students have never been identified for intervention through direct observation. The researchers administered the Student Internalizing Behavior Screener (SIBS), which is a 7-item, teacher-completed, Likert-type scale which measures occurrences of internalizing problem behaviors. Once scores from the SIBS were calculated, students who scored at-risk were chosen for observation …

Vulnerable Narcissism, Difficulties In Emotion Regulation, And Relational Aggression In College Students, Shelby E. Caffarel

Honors Theses

Relational aggression is a form of aggressive behavior involving the intentional infliction of harm to the victim’s sense of belonging, reputation, or social relationships. Although most of the research on relational aggression has focused on children and early adolescents, there is evidence that it can be a serious problem for college students as well. Several predictors of relational aggression have been identified, but the mechanisms through which many of them operate is not sufficiently clear. The present study examined the relationship of vulnerable narcissism and difficulties in emotion regulation to relational aggression in a college student sample. It was expected …

Mindfulness In Medicine: Modified Mindfulness-Based Stress Reduction (Mbsr) Program Among Future Doctors, Virtue Sankoh

Dissertations, Theses, and Capstone Projects

Medical trainees are at particular risk for stress-related illness, including mental health problems such as suicidal ideation, substance abuse, and mood disorders. A vast literature on mindfulness-based stress reduction (MBSR), consisting of mindfulness education and structured meditative practices, has consistently demonstrated that MBSR and related mindfulness-based interventions improve mental and physical health, as well as one’s overall sense of well-being. Moreover, theorists and researchers have begun to suggest further that mindfulness plays a particular role in social cognition, or social-emotional learning. Medical schools have long been interested in ways to improve the “soft skills” related to interpersonal connectedness that are …

Relational Processes In Support-Related Communication Among Young Adults With Cancer, Kathleen Darabos

Dissertations, Theses, and Capstone Projects

Despite decades of studies reporting positive associations of social support with cancer-related quality of life, little attention has been paid to understanding how relational qualities (e.g., self-disclosure, perceived support member disclosure, perceived support member responsiveness) of cancer-related support exchanges might influence psychological adjustment and intimacy among young adults with cancer. Further, little attention has been paid to understanding how young adults with cancer communicate with their social support networks among different modes of communication [(face-to-face vs. technology-related (e.g., text message, social media)] remains poorly understood. Questionnaire data from 45 young adults with cancer combines these two separate but related literatures …

Queerness, Witchcraft, And Embodied Presence: Aesthetic Knowings Of What A Body Can Do, Megan Bigelow

Dissertations, Theses, and Capstone Projects

Taking as a point of entry the critique of representation and affirming the limitations of the cuts that language makes, this capstone project explores the imbrications and assemblages between Foucault’s concept of subjugated knowledges, witchcraft and other body-based ways of knowing and being, and the consciousness of non-human forms such as plants and through the framework of non-representational theory, process philosophies, aesthetics, queerness, and the concept of difference itself.

Since such theories themselves are living, breathing entities, this capstone project explores the ideological split that has occurred between sacred and secular beliefs, moving through different figures such as nuns and …

Different Strokes For Different But Reasonable Folks: Comparison Of Legally Relevant Observers’ Perceptions Of Custody, Fabiana Alceste

Dissertations, Theses, and Capstone Projects

The Fifth Amendment guarantees the right against compelled self-incrimination. In Miranda v. Arizona (1966), the U.S. Supreme Court extended this right to police interrogations. In that landmark ruling, the Court required police to inform suspects in custody of their rights to silence and counsel during custodial interrogations. Custody is determined by evaluating the objective circumstances of the questioning and asking whether a reasonable person would have felt free to leave. Previous research on attributions of freedom shows that people perceive situations with regard to freedom differently depending on their perspective—for example, a person in a stressful situation may not feel …

Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann

Dissertations, Theses, and Capstone Projects

Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.

Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …

Examining Emotional Pain Among Individuals With Chronic Physical Pain: Nomothetic And Idiographic Approaches, Madelyn Frumkin

Arts & Sciences Graduate Student Theses and Dissertations

Pain is often conceptualized as an experience that is both physical and emotional. These two components are often difficult to distinguish, which may contribute to the experience of chronic physical pain without an apparent physical cause. In the current two studies, I sought to examine whether emotional pain is associated with physical pain severity for individuals with chronic pain. Emotional pain and the more specific experiences of psychological and social pain have been defined as the experience of pain affect in response to non-physical stimuli (i.e., thwarted belongingness, loss, social rejection). In Study 1, I found that emotional and psychological …

Face Affect Perception In Schizophrenia And Posttraumatic Stress Disorder, Lisa Beckman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia (SZ) and Posttraumatic Stress Disorder (PTSD) are often comorbid psychological disorders. Separately, research has previously demonstrated deficits in social cognition, including affect recognition impairment in both disorders; however, less is reliably known about the specific deficits unique to a comorbid diagnosis of SZ and PTSD. This study examined the ability to correctly identify facial expressions in individuals diagnosed with SZ (n = 38) and PTSD alone (n = 20), comorbid SZ and PTSD (n = 26), and healthy controls (n = 28). Participants were administered a test battery to establish diagnoses of of schizophrenia and PTSD, and to evaluate …

Disordered Eating And Body Dysmorphic Concerns In Asian American Women: Sociocultural And Culture-Specific Predictors, Liya Akoury

UNLV Theses, Dissertations, Professional Papers, and Capstones

The sociocultural idealization of thinness and Eurocentric features (e.g., lighter skin) is ubiquitous in Westernized cultures, yet only some women internalize these ideals and/or perceive heightened pressures to conform to such ideals. Elevated internalization and perceived pressures to obtain thinness and Eurocentric features may contribute to disordered eating and unique types of body dysmorphic concerns (e.g., dissatisfaction with skin color, eye size/ shape), respectively. Such difficulties may be particularly relevant for ethnic minority women; however, little research exists examining such effects. Further, few studies have comprehensively examined the intersection between sociocultural and culture-specific (e.g., ethnic identity; biculturalism) predictors on disordered …

Necessary And Sufficient: Examining The Role Of Attachment Trauma And Psychological Maltreatment As Primary Etiological Factors In The Development Of Borderline Personality Disorder, Chacy Agnello

Dissertations

Current widely-accepted conceptualizations regarding borderline personality disorder (BPD) profess that trauma is not required in the etiology of BPD and place a significant focus on biological predispositions. This review sought to evaluate the current paradigms regarding BPD and examine whether trauma may be the most significant contributing factor in the development of BPD. Studies on developmental trauma (including psychological maltreatment) and attachment were examined. These studies appear to strongly support the idea that when disrupted attachment and psychological maltreatment are taken into consideration, trauma does appear to be both necessary and sufficient as primary etiological factors in the development of …

Resilience To Post-Traumatic Stress Symptoms In Child Survivors Of Childhood Sexual Abuse, Caroline Witek

Theses and Dissertations

Just as adults may develop post-traumatic stress disorder (PTSD) after being exposed to death, serious injury, or sexual violence, so too may children. Childhood sexual abuse (CSA) is one traumatic event that has been linked to the development of post-traumatic stress symptoms (PTSS) in children. While the literature to date has drawn strong connections between CSA and subsequent psychopathology (including PTSD diagnoses), and explored factors contributing to resilience to psychopathology development, comparatively little research has been conducted on factors that increase child CSA survivors’ resilience to post-traumatic stress symptom development. Furthermore, much of the research to date has explored long-term …

Training Caregivers To Implement A Structured Meal Protocol To Decrease Food Selectivity Among Young Children With Autism, Ronald Joseph Clark

Theses and Dissertations

This study evaluated a method of training caregivers to implement the Structured Meal protocol to treat children with autism who exhibit food selectivity. A treatment package consisting of written instructions and video modeling as well as in-vivo prompting and feedback (when necessary) was used to teach participants to conduct the protocol. A multiple baseline design across participants was used to evaluate the effects of training. In addition to the primary dependent variable (i.e., correct caregiver implementation of the Structured Meal protocol), data on three secondary dependent variables (i.e., child bite acceptance, mouth cleans, and inappropriate mealtime behavior) were collected. Results …

Trends In The Rate Of Inpatient Pediatric Bipolar Disorder Diagnosis Between 1996 And 2015, Samantha Sherwood

UNLV Theses, Dissertations, Professional Papers, and Capstones

The rate of PBD in the U.S. increased dramatically between the mid-1990s and mid-2000s resulting in concern regarding the potential for misdiagnosis of PBD. However, given that the rate of PBD diagnosis had not been examined in the U.S. since 2004, the longitudinal trajectory of PBD diagnosis subsequent to the mid-2000s was unclear. Therefore, the present study utilized two datasets of administrative billing claims to assess whether longitudinal changes in the rate of inpatient PBD diagnosis continued to occur subsequent to 2004. Study 1 utilized a nationally representative dataset of inpatient psychiatric hospitalizations between 1996 and 2010. De-identified data were …

Elucidating The Lasting Influence Of Early Pubertal Timing On Disordered Eating Symptoms, Megan Marie Shope

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Extant data indicate that girls who mature earlier than their peers are at increased risk for disordered eating symptoms. Nonetheless, whether early pubertal timing exerts differential effects across key disordered eating symptoms (e.g., body weight/shape concerns vs. binge eating) and whether pubertal timing effects are present after the completion of puberty (i.e., in adulthood) remains relatively unclear. Additionally, leading theories posit that pubertal increases in adiposity and psychosocial factors (e.g., perceived pressures for thinness) likely underlie the predictive effects of earlier maturation on disordered eating risk, yet few studies have empirically tested this possibility. The current study aimed to …

Exploring Prenatal Risk Factors Among Hispanic Children With Autism Spectrum Disorders. – A Pilot Study In The Rio Grande Valley, Lauren Tien

Dissertations and Theses (Open Access)

Background: Peer-reviewed studies suggest that a hostile gestational environment is associated with delayed neurological development in infants. Autism spectrum disorder (ASD) is estimated to affect 1 in 59 children in the United States; however, few studies have specifically investigated risk factors for autism in Hispanic children. Purpose: The University of Texas RGV Hispanic Autism Research Center (HARC) studied Hispanic children with ASD and their biological mothers to identify potential environmental exposures and prenatal risk factors that could impact the risk for ASD through preliminary research in the Rio Grande Valley. Methods: This pilot study recruited 25 Hispanic mothers and their …

Racial Becoming: How Agentic (Self-Initiated) Encounter Events Inform Racial Identity Refinement, Devin A. Heyward

Dissertations, Theses, and Capstone Projects

Racial identity literature has typically focused on identity formation through a series of stages. It also has centered how the experience of negative encounter events informs racial identity formation. With the advent of new genealogical and genomic technology, it is imperative to expand the focus of identity literatures to include encounter events, which participants elect to experience (i.e. self-initiated or agentic encounter events). By using this frame, identity processes become fluid and informed by individual life experiences. In the context of this study, direct to consumer genetic ancestry tests (DTC-GAT) are operationalized as a self-initiated encounter event. Participants were …

Who Needs Blame?: Answerability Without Expressed Blame, Sarah Gokhale

Dissertations, Theses, and Capstone Projects

This dissertation argues that we can hold other agents morally responsible without expressing blame and, more strongly, that doing so is preferable. I first argue that blame is fundamentally retributive, and that blame’s retributive foundation is incipiently present even in civilized guises. As such, even though some forms of expressed blame are quite civilized, expressed blame always involves a risk of emotional damage, entrenchment, and escalation. To make things worse, I argue that anger is an exacerbating feature of blame’s retributive foundation. I then argue that, generally speaking, cases of public blame involve higher stakes than cases of private judgments …

The Measure Of A Man: A Critical Methodology For Investigating Essentialist Beliefs About Sexual Orientation Categories In Japan And The United States, Brian R. Davis

Dissertations, Theses, and Capstone Projects

Methods for studying laypeople’s beliefs about sexual orientation categories have evolved in step with larger theoretical and epistemological shifts in the interdisciplinary study of sexuality. The dominant approach to measuring laypeople’s sexual orientation beliefs over the past decade was made possible through an epistemological shift from a nature vs. nurture paradigm to a social constructionist theoretical model of psychological essentialism (Medin, 1989; Medin & Ortony, 1989; Rothbart & Taylor, 1992). Despite this shift, I argue that the forced-response scale-based survey methodologies typically used to operationally define essentialist beliefs about sexual orientation at best only partially realize the social constructionist potential …

Effects Of Genre Tag Complexity On Popular Music Perception And Enjoyment, Lauren Shepherd

Graduate Theses and Dissertations

The popular online streaming platform Spotify added over 1400 genre tags in the last two years. Despite that numerous artists and composition competitions claim to seek projects that “transcend the traditional notion of genre,” the industry has only added more complex and mystifying genre labels. This dichotomy between artists and industry ignores the effects these labels have on consumers. Do more complex genre tags enhance the listening experience for the average consumer by providing additional information about what they are about to hear? The current research seeks to examine the effects of the granularity of genre tags on popular music …

Religious Attendance, Surrender To God, And Suicide Risk: Mediating Pathways Of Feeling Forgiven By God And Psychopathology, Kelley Pugh

Electronic Theses and Dissertations

Suicide is a national public health concern, and college students may be at increased risk. Symptoms of psychopathology (i.e., stress, anxiety, and depression) may contribute to risk, whereas religiosity (i.e., religious attendance, surrendering to God, and feeling forgiven by God) may reduce risk. Students from a rural southeastern university (N=249) completed self-report measures. Serial mediation analyses indicate that attendance and surrender to God are inversely- predictive of suicide risk, both directly and through the indirect pathways of feeling forgiven by God (1st order mediator) and psychopathology (2nd order mediators). In all models, specific indirect effects occurred through feeling forgiven by …

Pocket Ace: Neglect Of Child Sexual Abuse Survivors In The Aces Study Questionnaire, Robyn Dolson

Electronic Theses and Dissertations

In 1998, a seminal study on adverse childhood experiences (ACEs) and subsequent health risks catapulted ACEs and the study questionnaire into the zeitgeist. However, its childhood sexual abuse (CSA) item is problematic as it requires the perpetrator have been 5-years or older than the victim. To assess whether some survivors’ CSA is not identified by the current item, whether their exclusion prevents access to services requiring a four-threshold ACE score, and how their health outcomes compared to other CSA groups and controls, an international sample of 974 women completed an online survey assessing their current health and CSA history using …

A Phenomenological Study Of The Lived Experiences Of Counseling Students In A Co-Facilitated Experiential Group, Alexandra Meyers

Graduate Theses and Dissertations

Research in the fields of experiential learning, group psychotherapy, and neuroscience has supported the inclusion of the experiential group in counseling training programs due to the potential for positive impact on students’ personal and professional development (Badenoch & Cox, 2010; Denninger, 2010). Investigations exploring counseling students’ experiences of the experiential group have been primarily limited to quantitative studies, while in-depth qualitative inquiry has been minimal. Additionally, an extensive review of the literature has found there have been no qualitative studies examining experiential groups co-facilitated by a course instructor and a doctoral student. The purpose of this phenomenological study was to …

Electrophysiological Correlates Of Visual Object Category Formation In A Prototype-Distortion Task, Stephanie Marie Long

Graduate Theses and Dissertations

In perceptual learning studies, participants engage in extensive training in the discrimination of visual stimuli in order to modulate perceptual performance. Much of the literature in perceptual learning has looked at the induction of the reorganization of low-level representations in V1. However, much remains to be understood about the mechanisms behind how the adult brain (an expert in visual object categorization) extracts high-level visual objects from the environment and categorically represents them in the cortical visual hierarchy. Here, I used event-related potentials (ERPs) to investigate the neural mechanisms involved in object representation formation during a hybrid visual search and prototype …

Reducing The Risk: Psychological And Technological Approaches For Improving Handwashing Practices In The Foodservice Industry, Jeffrey Allan Clark

Graduate Theses and Dissertations

As Americans are spending greater portions of their dollar on food consumed outside the home, the foodservice industry plays more of an integral part of daily existence compared to previous generations. Given the numerous annual foodborne illness outbreaks that threaten human lives while undermining confidence in the food supply, food safety is a pertinent issue for industry stakeholders, government regulators, and consumers. Food worker handwashing reduces the risk of foodborne illness transmission, yet compliance with this simple behavior is a complex problem. This dissertation addresses, predominantly, the issue of sub-optimal handwashing practices through applying psychology and technology, including wearable computers …
