Concurrent Neurological And Behavioral Assessment Of Number Line Estimation Performance In Children And Adults, Joseph Michael Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the brain’s response to common math-learning activities may help improve math education. For example, by imaging the brains of typically developing children and adults throughout a number line estimation task, it is possible to establish a baseline of what “typical” brains do in such situations. Thus, comparisons may be made to determine the degree to which brain functioning differs between typical and atypical math learners. Moreover, by identifying methods that may increase the brain’s response to real-world math activities, it may be possible to improve the math learning process for typical and atypical learners alike.

Brain imaging devices such …

The Psychological And Physiological Effects Of Using A Therapy Dog In Mindfulness Training, Courtney L. Henry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the psychological and physiological effects of adding animal-assisted therapy to a modified mindfulness-based stress reduction program (MBSR) for clients experiencing psychological distress, including anxious and depressive symptoms. State and trait mindfulness, state and trait anxiety, psychological distress, blood pressure, and heart rate were collected during each session of the intervention from college students recruited at Utah State University. Results support that participants experienced less anxiety and depressive symptoms and increased mindfulness skills from pre- to posttreatment. No significant difference was found between the control and experimental groups, indicating that that interaction with a therapy dog had no …

An Evaluation Of A Computer-Based Training On The Visual Analysis Of Single-Subject Data, Katie Snyder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Federal education policies, such as No Child Left Behind and the Individuals with Disabilities Education Improvement Act, mandate the use of scientifically-proven or research-based curricula and interventions. Presumably, interventions that have a large amount of scientific evidence documenting their success are more likely to be effective when implemented with students in school settings.

In special education, single-subject research is the predominant methodology used to evaluate the effectiveness of interventions. In single-subject research, a target behavior is measured under baseline conditions (i.e., before the intervention of interest is implemented) and intervention conditions. The data for each condition are graphed, and analyzed …

A Comparison Of Resistance To Extinction Following Dynamic And Static Schedules Of Reinforcement, Andrew R. Craig

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavioral momentum theory states that the Pavlovian stimulus-reinforcer relation governs resistance to extinction. Thus, higher baseline reinforcer rates should produce more persistent behavior than lower baseline reinforcer rates. Though this positive relation generally is observed when behavior is maintained and subsequently disrupted in multiple schedules, the opposite relation is observed when single schedules are used. An alternative framework of extinction performance based on Bayesian change detection may be applied intuitively to describe resistance to extinction in single schedules of reinforcement. This approach asserts that detection of changes in reinforcer rates during extinction should be easier following training with rich reinforcer …

The Relation Between Parenting Beliefs, Behaviors, And Acculturation On The Social Skills Of Prekindergarten Hispanic Children, Peter C. Winstead

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research related to the importance of social skills in children shows that they are important to children's development and performance in school. Research on problem behaviors in children, such as bullying, have been shown to be related to negative outcomes later in life for children such as lower performance in school, and juvenile and adult criminal behavior. What parents believe and how they act on those beliefs have been found to be related to fewer problem behaviors, and to higher social skills in children. However, the research we have has focused on the parenting behaviors and social outcomes in children …

Facebooking For Social Support: An Experimental Test Of Relational Regulation Theory, Odessia Knowles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transitioning to college can be difficult. While some individuals choose to attend a college that is local to their home, others move away from their family and friends to
attend their college of choice. This move adds additional stress to the already stressful nature of attending college. Research suggests that having social support can help with this additional stressor. However, individuals who move away from their family and friends may have difficulty receiving social support in their new, unfamiliar environment.

Facebook is a well-known, widely used form of social media with a significant number of users worldwide. College students spend …

Perceptions Of Interethnic Dating Among College Students, Elisaida Méndez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Department of Psychology at Utah State University proposed to examine the intersection of demographic variables. This phenomenon was studied in the context of power differential in relationships under the framework of social exchange theory and a racial hierarchy. The study examined the role of ethnicity, income, and gender in status and power balances in the perception of success of dating relationships. Social exchange theory explains the exchange of traits or resources in interpersonal relationships and relationship formation and based on a racial or ethnic hierarchy, race or ethnicity is seemingly overlooked when considering other valued traits.

The Interethnic Couples …

The Influence Of Widowhood And Sociodemographic Moderators On Dementia And Alzheimer's Disease Risk, Daniel Joseph Hatch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dementia and Alzheimer’s disease (AD) are dramatic public health problems. In recent years, researchers have uncovered evidence demonstrating that chronic stress can lead to these conditions. Because of this, researchers have also investigated whether widowhood, one of the most stressful life events, may also lead to dementia and AD. However, these studies are conflicting, and few have investigated whether the influence of widowhood on dementia and AD varies in different contexts associated with aging and widowhood. For instance, evidence suggests that widowhood may exert greater influence among males and among those with a history of depression. Other such contextual factors …

Utility Of An Error Analysis And Performance Deficit Assessment For Selecting Brief Interventions To Increase Math Fluency, Aaron John Denison

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children who struggle with math fluency are typically not provided with the appropriate motivation and instruction for their needs in the regular education classroom. Because of their lack of math fluency skills, these children can be negatively affected throughout their education and can continually fall further behind their peers. It is clear that children who struggle with math fluency should be provided with interventions specific to their needs in order to thrive in a school environment. Thus, it is critical that school psychologists and researchers develop effective strategies for children who are struggling with math fluency in order to help …

Mapping The Online Gambling E-Servicescape: Impact Of Virtual Atmospherics On The Gambler's Experience, Brett Lillian Levine Abarbanel

UNLV Theses, Dissertations, Professional Papers, and Capstones

A structural model is proposed and empirically examined that investigates the influence of an online casino's atmospheric cues on consumer behavioral response. A stimulus-organism-response (S-O-R) model, often used to frame other servicescape research, is adapted as the basis of the theory that the online casino environment will influence the organismic effects of cognitive and affective states, which in turn influence gamblers' approach or avoidance behavioral intentions. Analyzed elements of the online gambling site stimulus include high and low task-relevant cues, financial trust, and gambling value. Personal and situational factors and demographic characteristics were found to moderate the relationship between atmospheric …

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 …

How We Complain: The Effect Of Personality On Consumer Complaint Channels, Riley Allen Berry

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to explore any connections that may exist between personality types and consumer complaint channels. A sample of 490 undergraduate students at the University of Nevada Las Vegas was surveyed during class time with a paper and pencil survey. The survey consisted of four service failure scenarios each with eleven possible courses of action. Respondents were asked to rate their likelihood to participate in each action on a seven point Likert-type scale. The three personality factors measured against the complaint behavior were Locus of Control, The California Psychological Inventory measure of Sociability, and Cattel's 16 …

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 …

Motives For Different Types Of Medical Travelers: An Analysis Of The Current State Of Academic Research On The Topic, Dan B. Cormany

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research is to determine the current state of research undertaken to provide insight into the motivational characteristics of medical travelers, as reported by scholarly publications in the last five years. As a part of the study, an exploration is undertaken of the four basic schools of psychological thought, as each have different explanations for human motivation. These four schools - psychodynamic, behavioral, humanistic, and cognitive or pragmatic - are examined in the light of six categories of medical travelers. The categories are those traveling for life-saving surgeries, for treatments to improve quality of life, for elective …

Resilience And Trauma In Maltreated Youth, Timothy Day

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research into resilience represents a theoretical shift from the medical model in contemporary psychology to a focus on adaptation (Poulou, 2007). The relationship however between resilience and the development and PTSD in children remains unclear. The purpose of this present study is to expand on this research by investigating resilience and adaptability with respect to Posttraumatic Stress Disorder (PTSD) symptoms across maltreated youth of different ethnicities at risk for PTSD. Participants will be recruited from a Department of Family Services (DFS)-affiliated clinic in the Las Vegas area and administered the Children's PTSD Inventory (CPTSD-I), Behavior Assessment System for Children-2 Parent …

School Nurses' Recognition, Attitudes, And Educational Needs Regarding The Care Of Children With School Refusal Behavior, Heather Strasser

UNLV Theses, Dissertations, Professional Papers, and Capstones

School refusal behavior can prevent a child from attending school or staying in class for a full day of instruction. School nurses are often one of the first professionals in the school with the opportunity to interact with these children, recognize school refusal behavior and its debilitating impact, and positively intervene to assist these children to stay in school. Few studies have examined school nurse recognition and attitudes regarding school refusal behavior. The purpose of this study was to assess school nurses' recognition of school refusal behavior, their attitudes regarding the nursing care of children with school refusal behavior, and …

An Empirically-Supported Model Of Posttraumatic Stress Disorder In Maltreated Youth, Adrianna Wechsler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Posttraumatic stress disorder in maltreated youth is a young and burgeoning field. Lemos-Miller and Kearney (2006) were among the first to propose and test a theoretically and empirically-based model of PTSD in maltreated youth. The present study replicated and evaluated the Lemos-Miller and Kearney model within a larger and more diverse sample of maltreated adolescents. First, the Lemos-Miller and Kearney model was tested via structural equation modeling (SEM). Second, the model was evaluated across age, gender, and ethnicity. Third, trauma history, family environment (i.e., cohesion and conflict), dissociation, and trauma-related cognitions were evaluated as potential mediating variables within the model. …

Delay And Probability Discounting Functions Of Adults With Attention-Deficit/Hyperactivity Disorder (Adhd), Gretchen Scheidel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Impulsivity and risk-taking behaviors, concerns that are common for individuals with ADHD, can be measured using computerized tasks called delay and probability discounting measures. These measures can look at differences between individuals with ADHD and peers who do not have ADHD to determine how similar or different they are regarding these concerns. Individuals with ADHD often take stimulant medications, such as Ritalin or Adderall, to help reduce their impulsivity, hyperactivity, and risk-taking behaviors. The present study examined impulsivity and risk-taking for adults with ADHD while taking their stimulant medication and while not taking it, as well as comparing them to …

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 …

The Relationship Between Acculturation And Depression Among First Generation Christian Arab American Adults, Salma Khshaiboon

Seton Hall University Dissertations and Theses (ETDs)

Contrary to the common belief that most Arab Americans are Muslim, 77% of Arab Americans are Christian (Awad, 2010). There is no research that addresses the unique experience of Christian Arab Americans with the process of acculturating to the larger American society while maintaining the values of their ethnic group. The purpose of this study is to measure levels of acculturation with its two factors; ethnic society immersion and dominant society immersion, and depression with its two factors; cognitive-affective and somatic-vegetative and examine the relationships between them. In the current study, 101 Christian Arab American participants (ages 18 and above) …

Pathways To Social Functioning Via Emotion Regulation In People With Serious Mental Illness, Hayden C. Bottoms

Department of Psychology: Dissertations, Theses, and Student Research

Recent research on social cognitive deficits associated with serious mental illness (SMI) has demonstrated a range of emotion processing difficulties, from emotion perception to emotion regulation. Whereas emotion perception deficits are well documented in this population, little is understood about emotion regulation and the relationship of emotion regulation to other abilities and impairments.

Method. Participants included 41 individuals with SMI recruited from a day rehabilitation program. Assessments included a range of functional domains, including symptom severity, neurocognition, social cognition, emotion regulation, and social functioning.

Results. Emotion dysregulation was hypothesized to be associated with more severe positive symptoms, poorer neurocognitive …

Dispositional Mindfulness As A Moderator Of Electrocortical And Behavioral Responses To Affective Social Stimuli, Jordan T. Quaglia

Theses and Dissertations

Numerous studies have linked dispositional mindfulness to enhanced emotion regulation. The present research examined dispositional mindfulness as a predictor of emotion regulation in social affective contexts. Participants completed passive viewing and Emotional Go/No-Go tasks involving social affective stimuli (happy, neutral, and fearful facial expressions). Event-related potentials (ERPs) and behavioral responses were examined to discern whether dispositional mindfulness predicted differential neural and behavioral responses indexing attention to, awareness of, and inhibitory control over automatic responses to affective social stimuli. Dispositional mindfulness predicted larger (more negative) N100, N200 and No-Go N200 amplitudes during the Emotional Go/No-Go task, but was not associated with …

An Evaluation Of Culture-Specific Risk Factors And Emotion Regulation Strategies On Psychological Distress And Maladaptive Behaviors Among Asian Americans, Joo-Hyun Lee

Master's Theses and Doctoral Dissertations

Cultural context is fundamental in cross-cultural conceptualizations of risk factors for mental health status among ethnic minorities. Existing studies indicate that acculturation level predicts psychological adjustment, but findings remain inconclusive. This study, consisting of university students of Asian descent, evaluated the relationship between acculturation level and internalizing/externalizing problems via the incorporation of more proximal measures of risk factors associated with acculturation (e.g., acculturative dissonance and acculturative stress). In addition, the predictive values of non-culture specific risk factors, such as emotion dysregulation and experiential avoidance, were examined. Acculturation-related stressors and difficulties with emotion regulation increased risk for maladjustment within the study’s …

Revisiting Cognitive Dissonance Theory:Pre-Decisional Influences And The Relationship To The Consumer Decision-Making Model, Paul J. Costanzo Dr.

Atlantic Marketing Journal

This paper examines pre-decisional dissonance as a motivating factor in consumer decisional-making. A review of the marketing literature found the majority of research studies were limited to post-decisional influences. Several studies including measures of pre-decisional activity linked the construct to post-decision situations. The author provides evidence regarding the popularity and resurgence of research on cognitive dissonance theory and asserts that researchers in the field of consumer behavior may gain a better understanding of consumer decision-making when studying pre-decisional consonance and dissonance as separate entities and independent of post-decisions.

Level Of Cooperativeness And Competitiveness In Relation To Sports Choice In Children, Rachel Choinski

Honors Projects in Applied Psychology

The topic which I have chosen for my senior capstone project is in the psychology field and involves children’s personalities, in particular the level of cooperativeness and competitiveness, and their sports preferences. The literature research covered the child’s skill level, mainly motor skills which the children possess, competitive and cooperative sports categories as well as family influence, each which have an effect on this study. The five hypotheses which are being examined are: competitive children will prefer the competitive sports over the cooperative ones, cooperative children will prefer cooperative sports, level of competitiveness and cooperativeness will have an effect on …

The Effects Of Rating Accuracy On Treatment Fidelity, Joshua Labeff

Honors Theses

The current study attempts to evaluate if there is a relationship between treatment fidelity and interobserver agreement. Participant performance on rating the accuracy of a video demonstration of a functional analysis session was analyzed in comparison to their performance in implementing a mock functional analysis session. Video models (some with confederates and some with the actual participant) of functional analysis conditions were shown to and graded by participants and were immediately followed by their participation in a mock functional analysis session with a confederate child. The results of the study tend to show little to no relationship between the two …

Uncertainty And Primary Appraisal As Predictors Of Acute Stress Disorder In Parents Of Critically Ill Children: A Mediational Model, Monica Durrette

Theses and Dissertations

This study examined illness-related uncertainty and primary appraisals of threat, centrality, and challenge as predictors of acute stress disorder (ASD) symptoms in parents of children hospitalized in a pediatric intensive care unit (PICU). Ultimately, a mediational pathway was tested to determine if primary appraisal was a mechanism that accounted for the impact of uncertainty on ASD symptoms. Ancillary study aims were to assess the degree to which parents perceived uncertainty in the PICU environment, and to determine the prevalence of ASD among parents in this setting. Self-report data was collected from 77 parents (57 mothers, 19 fathers) of children hospitalized …

Notions Of Spirits As Agents Of Mental Illness Among The Akan Of Ghana: A Cultural-Psychological Exploration, Annabella Opare-Henaku

Theses and Dissertations

The study explores lay conceptualizations of mental illness among the Akans of Ghana as influenced by their cultural worldview. Akan, the largest ethnic group in Ghana, is noted for the use of supernatural attributions for various health-related issues. The supernatural attributions are based on Akan ontological belief that the universe is unitary such that there is no clear distinction between physical and spiritual occurrences. This worldview guides Akans in how they deal with a wide range of issues including their mental health. Clinicians and other mental health professionals who rely solely on biomedical approaches to mental health fail to meet …

The Structure Of Addictions: A Confirmatory Factor Analysis Approach Using Structural Equations Modeling, Gabrielle Krus, Victoria Labitan, Katherine Paul, Kelly Perfect, Diana Stribl, Liz Hostetler, Sarah Braun

Symposium on Research and Creative Expression (SORCE)

Addiction is one of the most important mental health problems in contemporary society, but relatively little is known about how various kinds of addictive behaviors relate to each other. In this study, we take a complex structural model of addictions developed from Christian theological sources and our own previous research and test it against a large (N = 300) dataset of individuals who have rated their relationship to various objects of addiction. The analysis largely confirmed our theoretical model with some interesting modifications. We discuss implications of this research for addictions assessment and treatment.
