Defining Dimensions In Schizotypy: Factor Structure Replication And External Validation Of The Schizotypal Personality Questionnaire – Brief Revised Updated (Spq-Bru)., Elaina Montague

Department of Psychology: Dissertations, Theses, and Student Research

Background: Schizotypy is a construct that captures quantitative dimensions of the psychosis continuum from clinical to non-clinical expressions. The purpose of this study was to determine the factor structure and criterion validity of a newly revised self-report measure, the Schizotypal Personality Questionnaire–Brief Revised Updated (SPQ-BRU; Davidson, Hoffman, & Spaulding, 2016) for predicting later cognitive-perceptual experiences in college undergraduates.

Method: The data analytic sample was comprised of 2,474 undergraduate students (female = 71.9%) attending a university in the Midwest. First, we aimed to identify a model of best fit by comparing latent measurement models of schizotypy using confirmatory factor analysis (CFA). …

The Nmda Receptor Glun2c Subunit Controls Cortical Excitatoryinhibitory Balance, Neuronal Oscillations And Cognitive Function, Subhash C. Gupta, Aparna Ravikrishnan, Jinxu Liu, Zhihao Mao, Ratnamala Pavuluri, Brandon G. Hillman, Pauravi J. Gandhi, Dustin J. Stairs, Ming Li, Rajesh R. Ugale, Daniel T. Monaghan, Shashank M. Dravid

Department of Psychology: Faculty Publications

Despite strong evidence for NMDA receptor (NMDAR) hypofunction as an underlying factor for cognitive disorders, the precise roles of various NMDAR subtypes remains unknown. The GluN2Ccontaining NMDARs exhibit unique biophysical properties and expression pattern, and lower expression of GluN2C subunit has been reported in postmortem brains from schizophrenia patients. We found that loss of GluN2C subunit leads to a shift in cortical excitatory-inhibitory balance towards greater inhibition. Specifically, pyramidal neurons in the medial prefrontal cortex (mPFC) of GluN2C knockout mice have reduced mEPSC frequency and dendritic spine density and a contrasting higher frequency of mIPSCs. In addition a greater number …

Repairing The Broken Mirror: Understanding Men's Muscularity-Focused Body Image Concerns Through The Lens Of Gender Role Conflict And Self-Compassion., Michael S. Butchko

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Psychological research pertaining to the study of men and masculinity has discerned that men are increasingly becoming dissatisfied with their bodies. However, men’s body image research has been neglected as researchers originally concluded that only women were impacted. However, the last 20 years has begun to elucidate factors and consequences of muscularity-focused body image dissatisfaction among men. Particularly, some men engage in dangerous behaviors (e.g., excessive exercise, dieting, steroid use) in order to obtain a body with large biceps, chiseled chest, and defined abdominal muscles. Also, more men are experiencing characteristics of muscle dysmorphia (MD), a subtype of body dysmorphic …

Contributions Of Television Use To Beliefs About Fathers And Gendered Family Roles Among First-Time Expectant Parents, Patty X. Kuo, L. Monique Ward

Department of Child, Youth, and Family Studies: Faculty Publications

TV content has been documented to portray a limited range of gender roles, and to frequently depict fathers as incompetent parents. Accordingly, this study explored whether first-time expectant parents’ beliefs about gendered family roles and the importance of fathers to child development were related to their TV use. Participants were 201 individuals (122 women, 79 men) from across the United States expecting their first biological child in a cohabiting heterosexual relationship. Participants completed an online survey assessing weekly TV exposure, exposure to TV programs featuring fathers, perceived realism of TV, use of TV to learn about the world, and beliefs …

Sleep, Executive Control, And Psychopathology In Children: A Longitudinal Study And An Examination Of Brief Sleep Treatment, Katherine M. Kidwell

Department of Psychology: Dissertations, Theses, and Student Research

Researchers have acknowledged that poor sleep is not merely a symptom of psychopathology but also a contributing factor to the development of psychopathology in children (Walker & Harvey, 2010). However, more research is needed to explicate the associations among sleep, executive control (EC), and psychopathology. Specifically, there are few studies using longitudinal designs and limited research on how treating sleep can improve mental health symptoms. This dissertation provides a conceptual framework for the associations among sleep, EC, and psychopathology. The conceptual framework is bolstered by two studies. Study 1 is an examination of early sleep problems and preschool EC as …

Does Alcohol Mediate The Relationship Between Sexual Victimization And Risk Perception In A Date Rape Vignette, Kaylee N. Flower, Antover P. Tuliao, Dennis E. Mcchargue

UCARE Research Products

The present study used a date-rape vignette to examine the relationship between prior victimization, drinking habits (AUDIT score), risk perception. This was part of a larger study that analyzed sexual victimization and aggression. The present study looked at the 913 college-aged women that self-identified as heterosexual and bisexual at 2 mid-western colleges. They completed a battery of surveys that identified relevant history and behaviors. Findings suggest that the problematic drinking variable (AUDIT) mediates the relationship between prior victimization and risk perception.

Antipsychotic Drugs On Maternal Behavior In Rats, Ming Li

Department of Psychology: Faculty Publications

Rat maternal behavior is a complex social behavior. Many clinically used antipsychotic drugs, including the typical drug haloperidol and atypical drugs clozapine, risperidone, olanzapine, quetiapine, aripiprazole and amisulpride, all disrupt active maternal responses (e.g. pup retrieval, pup licking and nest building) to various extents. In this review, I present a summary of recent studies on the behavioral effects and neurobiological mechanisms of antipsychotic action on maternal behavior in rats. I argue that antipsychotic drugs at the clinical relevant doses disrupt active maternal responses primarily by suppressing maternal motivation. Atypical drug-induced sedation also contributes to their disruptive effects, especially that on …

Emotion Moderates The Association Between Htr2a (Rs6313) Genotype And Antisaccade Latency, Mark S. Mills, Olivia Wieda, Scott F. Stoltenberg, Michael Dodd

Department of Psychology: Faculty Publications

The serotonin system is heavily involved in cognitive and emotional control processes. Previous work has typically investigated this system’s role in control processes separately for cognitive and emotional domains, yet it has become clear the two are linked. The present study, therefore, examined whether variation in a serotonin receptor gene (HTR2A, rs6313) moderated effects of emotion on inhibitory control. An emotional antisaccade task was used in which participants looked toward (prosaccade) or away (antisaccade) from a target presented to the left or right of a happy, angry, or neutral face. Overall, antisaccade latencies were slower for rs6313 C allele homozygotes …

Behavioral Effects Of Phencyclidine On Nicotine Self- Administration And Reinstatement In The Presence Or Absence Of A Visual Stimulus In Rats, Natashia Swalve, Steven T. Pittenger, Rick A. Bevins, Ming Li

Department of Psychology: Faculty Publications

Rationale—Tobacco use is a serious health problem in the United States and this problem is potentiated in patients with schizophrenia. The reward system is implicated in schizophrenia and may contribute to the high comorbidity between nicotine use and schizophrenia but very little research has been done on the topic. The reward-enhancement effect of nicotine has been shown to be important in nicotine use, but there have been no studies on this effect in animal models of schizophrenia.

Objectives—This study was designed to determine the effects of phencyclidine, used to model negative symptoms of schizophrenia, on self-administration of nicotine with or …

Perceptions Of Well-Being In Nonmetropolitan Nebraska: 2016 Nebraska Rural Poll Results, Rebecca Vogt, Cheryl Burkhart-Kriesel, Randolph Cantrell, Brad Lubben, Larry J. Mcelravy Jr.

Publications from the Center for Applied Rural Innovation (CARI)

Certain indicators have pointed to overall economic growth in Nebraska. The state’s unemployment rate has remained among the lowest in the nation and wages have increased. However, net farm income continued to decline last year and employment growth in the state has been largely concentrated in the metropolitan counties. Given the challenges and uncertainties of recent years, how do rural Nebraskans believe they are doing and how do they view their future? How satisfied are they with various items that influence their well-being? Have these views changed over the past 21 years? This paper provides a detailed analysis of these …

Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills

Department of Psychology: Dissertations, Theses, and Student Research

The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …

Infant Language Assessment Predicts Later Math Disabilities, Aaron T. Halvorsen, Dennis Molfese

UCARE Research Products

Prevention of cognitive disabilities currently remains out of reach. Yet, interventions are crucial to maximizing developmental outcomes later in life. To be effective, interventions must occur at the earliest age possible to mitigate potential developmental problems. This study is an attempt to identify newborn infants at risk for developing math disabilities later in life. Several studies used assessment tests at relatively late ages in order to predict future cognitive abilities (Aarnoudse-Moens et al., 2013; Kiechl-Kohlendorfer et al., 2013). More recent research used MRI scans of neonate brains to investigate the relationships between academic abilities and preterm births (Ullman et al., …

Taking Charge 2016: A Study Of The Strategic Budgeting Priorities Of The Residents Of Lincoln, Nebraska, Lisa M. Pytlikzillig, Addison Fairchild

Lisa PytlikZillig Publications

This report presents the results of the 2016 Taking Charge initiative sponsored by the City of Lincoln. This initiative included an online survey and a half-day, face-to-face, Community Conversation. Most previous Taking Charge activities have focused more narrowly on the immediate concerns of an impending budget proposal (e.g. which specific programs should be funded or discontinued to maintain a balanced budget). This year’s efforts also focused on specific items relevant to the City’s future budget policy priorities. As usual, residents were also given the opportunity to rate the City’s performance and City officials on a variety of performance characteristics.

Differing Perspectives On Older Adult Caregiving, Eve M. Brank, Lindsey E. Wylie

Department of Psychology: Faculty Publications

Informal older adult caregiving allows older adults to stay in their homes or live with loved ones, but decisions surrounding older adult care are fraught with complexities. Related research and case law suggest that an older adult’s need for and refusal of help are important considerations; the current study is the first to examine these factors experimentally. Two samples (potential caregivers and care recipients) provided responses regarding anticipated emotions, caregiver abilities, and allocation of daily caregiving decision making based on a vignette portraying an older adult who had a high or low level of autonomy and who accepted or refused …

Cumulative Contextual Risk At Birth In Relation To Adolescent Substance Use, Conduct Problems, And Risky Sex: General And Specific Predictive Associations In A Finnish Birth Cohort, W. Alex Mason, Stacy-Ann A. January, Mary B. Chmelka, Gilbert R. Parra, Jukka Savolainen, Jouko Miettunen, Marjo-Riitta Järvelin, Anja Taanila, Irma Moilanen

Department of Child, Youth, and Family Studies: Faculty Publications

Background—Research indicates that risk factors cluster in the most vulnerable youth, increasing their susceptibility for adverse developmental outcomes. However, most studies of cumulative risk are cross-sectional or short-term longitudinal, and have been based on data from the United States or the United Kingdom. Using data from the Northern Finland Birth Cohort 1986 Study (NFBC1986), we examined cumulative contextual risk (CCR) at birth as a predictor of adolescent substance use and co-occurring conduct problems and risky sex to determine the degree to which CCR predicts specific outcomes over-and-above its effect on general problem behavior, while testing for moderation of associations …

Uninvolved Maternal Feeding Style Moderates The Association Of Emotional Overeating To Preschoolers’ Body Mass Index Z-Scores, Maren Hankey, Natalie A. Williams, Dipti A. Dev

Department of Child, Youth, and Family Studies: Faculty Publications

Objective: To examine the relation between preschoolers' eating behaviors and body mass index (BMI) z-scores (BMIz) and the moderating role of permissive parent feeding styles in these associations.

Design: Cross-sectional study involving mothers' report of food-related parenting styles and child eating behaviors.

Setting: Small city in southern Mississippi.

Participants: Mother–preschooler dyads (n = 104).

Main Outcome Measure: Child body BMIz.

Analysis: Moderated multiple regression.

Results: An uninvolved feeding style moderated the relationship between emotional eating and BMIz such that children with higher emotional overeating scores had higher a BMIz in the presence of an uninvolved feeding style (B …

“Great Job Cleaning Your Plate Today!” Determinants Of Child-Care Providers’ Use Of Controlling Feeding Practices: An Exploratory Examination, Dipti A. Dev, Brent A. Mcbride, Katherine E. Speirs, Kimberly A. Blitch, Natalie A. Williams

Department of Child, Youth, and Family Studies: Faculty Publications

Background National early childhood obesity prevention policies recommend that child-care providers avoid controlling feeding practices (CFP) (e.g., pressure-to-eat, food as reward, and praising children for cleaning their plates) with children to prevent unhealthy child eating behaviors and childhood obesity. However, evidence suggests that providers frequently use CFP during mealtimes.

Objective Using the Academy of Nutrition and Dietetics (2011) benchmarks for nutrition in child care as a framework, researchers assessed child-care providers’ perspectives regarding their use of mealtime CFP with young children (aged 2 to 5 years).

Design Using a qualitative design, individual, face-to-face, semi-structured interviews were conducted with providers until …

Psychological Factors That Underlie Hazing Perceptions: A Mixed Methods Study, Jenna Strawhun

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The quantitative phase of this mixed-methods study examined psychological predictors, including previous bullying involvement, moral disengagement, the need to belong, and their influence on students’ perceptions of hypothetical hazing behaviors. The following qualitative phase was used to explain and contextualize Phase I results through an understanding of the psychological processes related to participants’ constructed meanings of their experiences as perpetrators, witnesses, and/or victims of bullying and hazing. Study participants for Phase I and Phase II included undergraduate students enrolled in psychology courses who participated in the study for research credit. Phase II participants also received a $25.00 gift card as …

Child And Parent Report Of Parenting As Predictors Of Substance Use And Suspensions From School, Charles B. Fleming, W. Alex Mason, Ronald W. Thompson, Kevin P. Haggerty, Thomas Jai. Gross

Department of Child, Youth, and Family Studies: Faculty Publications

This study examined how child and parent reports of parenting were related to early adolescent substance use and school suspensions. Data were from two time points six months apart on 321 families with an eighth grade student attending one of five schools in the Pacific Northwest. Child- and parent-report measures of family management practices were moderately correlated (r = .29). Child report, but not parent report, of more positive family management practices uniquely predicted a lower likelihood of adolescent substance use. Also, discrepancies between child and parent report of parenting predicted substance use, with child positive report of family …

Predicting Sexual Revictimization In Childhood And Adolescence: A Prospective Examination Using Ecological Systems Theory, Samantha L. Pittenger

Department of Psychology: Dissertations, Theses, and Student Research

Child sexual abuse is a prevalent problem in the United States and is associated with revictimization: a victimization episode perpetrated by a different individual and occurring subsequent to initial abuse experiences (Barnes, Noll, Putnam, & Trickett, 2009). While evidence shows that 20-39% of sexual abuse victims report revictimization within childhood or adolescence, much of the research to date has focused on its occurrence in adulthood. Thus, there is a limited understanding of the pathways to revictimization and its associated outcomes for youth. The present study examined predictors of sexual revictimization within childhood and adolescence using ecological theory, which includes individual, …

Examination Of Methamphetamine Reinstatement In Female And Male Rats: A Pre-Clinical Model Of Relapse, Steven T. Pittenger

Department of Psychology: Dissertations, Theses, and Student Research

Methamphetamine (meth) dependence is often characterized by persistent and chronic relapse (i.e., return to drug use). There is growing pre-clinical and human evidence suggesting females are at greater risk to relapse. The set of studies presented in this dissertation extended this limited evidence by identifying sex-dependent neural substrates correlated with meth-triggered reinstatement (Experiment 1) and by examining sex-differences in reinstatement triggered by drugs of abuse that are commonly co-abused with meth (Experiment 2). Female and male rats were trained to self-administer meth, received subsequent extinction sessions, and then tested for reinstatement. In Experiment 1, rats were perfused following reinstatement testing …

Standing Up Or Standing By: Examining The Bystander Effect In School Bullying, Scott M. Fluke

College of Education and Human Sciences: Dissertations, Theses, and Student Research

School bullying represents a serious mental health problem for youth in the United States. Bullying is a social phenomenon that is affected by the social context in which it occurs. Bystanders (i.e., individuals who witness bullying), are present in the vast majority of bullying situations. When bystanders choose to intervene on behalf of the victim, they are able to stop the bullying about 50% of the time. Unfortunately, bystanders rarely stand up for victims, instead frequently choosing to help the perpetrator or passively observe the bullying situation. Researchers have identified the bystander effect (i.e., the inhibitory effect of other bystanders …

College-Going Experiences Of Male Foster Youth Alumni Who Have Stopped-Out Of College, Felipe D. Longoria

Department of Educational Administration: Dissertations, Theses, and Student Research

This qualitative research study examined how foster care experiences and masculinities influenced male foster youth alumni’s decision to go to college. The study also sought to understand the in-and-out-of-college factors that led participants to exit college prematurely. Five participants were each interviewed twice for data collection purposes. Findings from data analysis indicated that establishing and maintaining relationships in college were challenging and affected an already vulnerable population in their help-seeking behavior. Recommendations are offered for higher education professionals and areas for future research are noted.

Sources Of Self-Efficacy Information For Writing: A Qualitative Inquiry, Mary E. Holmes

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This study explored the sources of information that inform students’ self-efficacy beliefs in the area of writing. A qualitative phenomenological case study approach was use to capture the experiences of gifted middle school students.

Writing is a critical skill for success in school and beyond, and many students in the United States are not able to adequately write extended texts (Bruning & Horn, 2000; National Center for Education Statistics, 2012). Understanding students’ motivation for engaging with writing might provide insight into how to better support students’ experience with writing in school. Self-efficacy is a key construct within motivation, and it …

Decision Making Theories Of Retaliation, Katlyn S. Farnum

Department of Psychology: Dissertations, Theses, and Student Research

In 2013, the Supreme Court decided, in University of Texas Southwestern Medical Center v Nassar, that Title VII retaliation claims should be interpreted under the stricter but-for causality instructions. This requires claims of retaliation to show that the plaintiff’s discrimination complaint (or involvement in a discrimination claim) is the direct cause of the adverse action, as compared to a motivating factor that is required under the less strict motivating factor causal instructions. The current research examines the role of regulatory focus (promotion v. prevention), causal instructions, employment action (promotion v. dismissal), and number of claims considered on both juror …

Daily Bidirectional Relationships Between Sleep And Mental Health Symptoms In Youth With Emotional And Behavioral Problems, Tori R. Van Dyk, Ronald W. Thompson, Timothy D. Nelson

Department of Psychology: Faculty Publications

Objective The present study examined the daily, bidirectional relationships between sleep and mental health symptoms in youth presenting to mental health treatment. Methods Youth aged 6 to 11 (36% female, 44% European American) presenting to outpatient behavioral health treatment (N = 25) were recruited to participate in the study. Children and parents completed daily questionnaires regarding the child’s sleep, mood, and behavior for a 14-day period, while youth wore an actigraph watch to objectively measure sleep. Results Examining between- and within-person variance using multilevel models, results indicate that youth had poor sleep duration and quality and that sleep and mental …

Tired, Hungry, And Grumpy: Understanding The Direct And Indirect Relationships Among Child Temperament, Sleep Problems, Feeding Styles, And Weight Outcomes, Alyssa Lundahl

Department of Psychology: Dissertations, Theses, and Student Research

Research indicates that temperament is related to later obesity risk in both childhood and adulthood (e.g., Anzman-Frasca et al., 2012; Darlington & Wright, 2006), but less research has examined the mechanisms underlying this relationship. It is likely that temperament influences factors that increase one’s risk for obesity, such as parental feeding practices and child sleep problems. As such, the primary aim of the present study was to provide rigorous concurrent and longitudinal examinations of temperament, feeding practices, sleep problems, and child zBMI in a sample of healthy preschool children. In addition, the moderating role of SES was examined. A secondary …

Successful Female Students In Undergraduate Computer Science And Computer Engineering: Motivation, Self-Regulation, And Qualitative Characteristics, Melissa Patterson Hazley

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Computer Science (CS) and Computer Engineering (CE) fields typically have not been successful at recruiting or retaining women students. Research indicates several reasons for this shortage but mainly from three perspectives: social issues, exposure/prior knowledge and curriculum issues in K-12 settings. This mixed-methods research addresses a gap in the literature by investigating the motivation and self-regulation behaviors of successful female students who are studying computer science and computer engineering. The findings in phase one of this study indicated that learning and performance approach goals predicted adaptive strategic self-regulation behaviors including strategy use, knowledge building and engagement. Learning avoidance goals predicted …
