Evaluating The Motivations Of Participants In Online Equine Extension Courses, Sarah Vos

Department of Animal Science: Dissertations, Theses, and Student Research

Traditional program evaluations emphasize participant demographics, knowledge gain, behavior change, and program impact. However, evaluating participant motivation can provide addition insight into why participants enroll in extension programs and help explain participant engagement and persistence throughout a program. The purpose of this study was to evaluate participant motivation in two online equine extension courses and examine potential relationships between motivation, demographics, and course delivery method, and describe participant engagement in Virtual Horse Judging Camp (VHJC). This cross-sectional study utilized convenience sampling of participants in two online equine extension courses, Horse Adult Leader Training and Educational Resource (HALTER) and VHJC. The …

The Impact Of Tier 1 Pbis Implementation Fidelity On Education Outcomes For Students With Attention-Deficit/Hyperactivity Disorder, Rebecca Anne (Wright) Overfield

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation study aimed to examine the relationship between Tier 1 Positive Behavioral Intervention and Supports (PBIS) implementation fidelity and the academic (e.g., MAP Growth scores) and behavioral outcomes (e.g., major office discipline referrals, suspensions). High quality PBIS implementation fidelity has been linked with improved standardized test scores and decreased instances of major office discipline referrals, in-school suspensions, and out-of-school suspensions for students with and without behavioral difficulties. However, no research has been done on the impact of PBIS implementation fidelity on students with ADHD. It is estimated that at least 40% of students with ADHD require at least one …

Study Protocol For A Randomized Controlled Trial Of Realconsent2.0: A Web‑Based Intervention To Promote Prosocial Alcohol‑Involved Bystander Behavior In Young Men, Laura F. Salazar, Dominic J. Parrott, David Dilillo, Sarah J. Gervais, Anne Marie Schipani‑Mclaughlin, Ruschelle Leone, Kevin Swartout, Lauren Simpson, Renita Moore, Tiffany Wilson, Nyla Flowers, Haley Church, Amanda Baildon

Department of Psychology: Faculty Publications

Background Sexual violence (SV) is a significant, global public health problem, particularly among young adults. Promising interventions exist, including prosocial bystander intervention programs that train bystanders to intervene in situations at-risk for SV. However, these programs suffer from critical weaknesses: (1) they do not address the proximal effect of alcohol use on bystander decision-making and (2) they rely on self-report measures to evaluate outcomes. To overcome these limitations, we integrate new content specific to alcohol use within the context of prosocial bystander intervention into an existing, evidence-based program, RealConsent1.0. The resulting program, RealConsent2.0, aims to facilitate bystander behavior …

Examining The Efficacy Of An Intervention Package Delivered Via An Online Learning Tool To Improve Prerequisite Algebra Skill Fluency, Nicole Bricko

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

This dissertation study investigated the efficacy of a multi-component intervention package delivered via an online learning tool on math fluency for prerequisite algebra skills for three 6^th-grade students. Students were referred by their math teacher due to concerns with academic performance. Target skills were individualized for each student based on screening assessments and measured continuously during both baseline and intervention. The multiple-probe across skills design demonstrated that students increased their math fluency on prerequisite skills. A staggered pattern of increases across skills for two participants indicated experimental control was achieved and student’s performance improved. The Quizlet^® intervention …

Dog And Owner Characteristics Predict Training Success, Jeffrey R. Stevens, London M. Wolff, Megan Bosworth, Jill Morstad

Jeffrey Stevens Publications

Teaching owners how to train their dogs is an important part of maintaining the health and safety of dogs and people. Yet we do not know what behavioral characteristics of dogs and their owners are relevant to dog training or if owner cognitive abilities play a role in training success. The aim of this study is to determine which characteristics of both dogs and owners predict success in completing the American Kennel Club Canine Good Citizen training program. Before the first session of a dog training course, owners completed surveys evaluating the behavior and cognition of their dog and themselves. …

Development Of A Minority Stress Preventive Intervention For Sexual And Gender Minority Youth And Young Adults, Natalie Holt

Department of Psychology: Dissertations, Theses, and Student Research

Mental health disparities amongst sexual and gender minority (SGM) individuals are spurred by exposure to minority stressors and sustained by mediators of problems with emotion regulation, social support, and cognitive processes. Emerging clinical research suggests empirically supported behavioral health treatments can be culturally adapted to address these mental health disparities, however less work has focused on the prevention of symptoms. The present study developed a brief preventive intervention targeting mediators of the minority stress model for SGM youth and young adults aged 17 to 26. Focus groups with 8 SGM participants informed development to ensure the content and delivery of …

Training Teachers To Differentiate Instruction To Address Work Completion Problems In Math, Elisabeth Kane

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

This dissertation investigated an adaptation of functional analysis methodology, performance deficit analysis (PDA), and its use in training teachers to differentiate instruction for students having difficulty completing independent math seatwork. Participants included three middle school teachers and one of their students who was referred for having difficulty completing his or her work. Behavioral skills training was used to individually train each teacher to interpret her student’s PDA data, determine if the student had a skill or performance deficit, and select appropriate motivational and instructional strategies to increase the student’s performance. To answer the research questions, a multiple-baseline-design across teachers was …

Enhancing The Rewarding Effects And Subsequent Self-Administration Of Nicotine Through Appetitive Interoceptive Conditioning, Allissa Flynn

Honors Program: Senior Projects (Public)

Nicotine is commonly considered to be the primary addictive constituent in tobacco products. Therefore, research focused on nicotine and its effects is necessary for understanding nicotine dependency and in developing potential cessation treatments. Research has confirmed the relevance of learning processes associated with nicotine and their influence on the development of addiction. Conditioning involving interoceptive stimuli is increasingly cited as playing a role in many diseases, psychopathologies, and drug addiction. The internal stimulus effects of nicotine can form associations with other reinforcing stimuli through a process of Pavlovian conditioning where nicotine is the conditioned stimulus. In this way, nicotine acquires …

Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Jeffrey Stevens Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

How Media Impact Race Relations: Positive And Negative Historical Examples And Applied Psychological Principles, Sophia Nocera

Honors Program: Senior Projects (Public)

This thesis sought to examine how media influenced interracial relations in the 1920s and 1930s. It starts by defining necessary terms like media, race, racism, and stereotypes. Afterwards, studies which demonstrate that media reflect society are analyzed as well as studies which determine the extent of media influence on society. Media are the most influential on people who agree with the content provided and those who have no specific opinion on the issue at hand.

Next, psychological studies which determine the circumstances in which racist ideology is accepted the most are analyzed. This analysis determined that in-group versus out-group sentiments …

Objectification In Heterosexual Romantic Relationships: Examining Relationship Satisfaction Of Female Objectification Recipients And Male Objectifying Perpetrators, Gemma Sáez, Abigail R. Riemer, Rebecca L. Brock, Sarah J. Gervais

Department of Psychology: Faculty Publications

Sexual objectification is one of most the common manifestations of discrimination against women in Western societies; however, few studies have examined objectification in the context of romantic relationships. The primary aim of the present research was to bring the study of objectification phenomena into the setting of heterosexual romantic relationships. The present set of studies examined the relation between sexual objectification and relationship satisfaction for both the sexual objectification recipient (Study 1) and the sexual objectification perpetrator (Study 2). The results of the first study with 206 U.S. undergraduate female students in committed romantic relationships replicated a previously identified negative …

Alcohol Expectancies Among Students In The City Of Pokhara, Nepal, Niran Tamrakar

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

Alcohol plays a vital role in various aspects of Nepalese society. It also presents public health risks. Though adolescents in Nepal are at high risk for negative consequences from alcohol use, there is limited information available on their alcohol behaviors and beliefs. The present study aims to describe alcohol expectancies among a sample of secondary students in Nepal to identify and understand motivations underlying their alcohol-related behaviors. A self-report survey was administered to 591 students from different Englishmedium schools in the city of Pokhara. This study began with the Chinese Adolescent Alcohol Expectancy Questionnaire (CAAEQ), then used qualitative methods to …

Parents Supporting Their Adolescents’ Independent Remedial Math Practice: The Effects Of A Multi-Component Intervention Package On Math Academic Performance, Mackenzie Sommerhalder

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

This dissertation examined the effects of high school students’ independent, remedial, home-based math practice while receiving parent support on math computation fluency. The multi-component intervention package encompassed both home-based remedial practice and parent support. Teacher interviews, normative assessments, and a performance-deficit analysis were conducted to identify high-school students who displayed math academic skill deficits. Next, identification and analysis of individual skills (e.g., multiplication, division) to be targeted for intervention occurred for each participant included in the study. A multiple-baseline across participants design was used to examine teaching high school students to choose effective instructional components for math computation and subsequently …

Adolescent Perceptions Of Dating Violence: A Qualitative Study, Sarah Taylor, Carrie A. Calkins, Yan Ruth Xia, Rochelle L. Dalla

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

Scholars have identified dating violence as a public health issue among adolescents. Yet, minimal research has detailed adolescents’ perceptions of dating violence, specifically gender differences in perceptions. Research suggests that in order for dating violence prevention and intervention to be effective, services need to be delivered in a manner that is understood by adolescents. Therefore, this study used a qualitative phenomenology study to investigate adolescents’ perceptions of dating violence, including gender differences in adolescents’ perceptions. Thirty adolescents between the ages of 14 and 19 from a Midwest public high school participated in focus groups. Focus group participants were asked semistructured …

The Making Of A Hero: Cultivating Empathy, Altruism, And Heroic Imagination, Ari Kohen, Matt Langdon, Brian R. Riches

Department of Political Science: Faculty Publications

Heroes are not born; they’re made. This article examines the commonalities in the backgrounds of people who take heroic action on behalf of others to theorize the ways in which our society can encourage citizens to prepare themselves to act heroically. In looking closely at a variety of people who have acted heroically, in a single moment or over time, we argue they have at least four crucial commonalities: They imagined situations where help was needed and considered how they would act; they had an expansive sense of empathy, not simply with those who might be considered “like them” but …

Emotion Regulation And Valance Bias, Drue Marr, Catherine Brown, Maital Neta

UCARE: Research Products

In this study we wanted to look at the affects of emotion regulation on individual differences in valance bias. The ability to regulate emotions brings into question how difficult/easy it is for individuals that have a more natural positive bias/disposition to them, or have a more natural negative bias/disposition to them. We would expect someone with a negative disposition to have a more difficult time regulating his or her emotions, as evidenced by the elevated EMG levels and EDA readings that we acquired. The purpose of this study was to better understand the way one perceives surprised expressions, as surprised …

The Relationship Between Executive Attention And Spatial Working Memory In Adults, Erica Ness, Emily Franzen, James Thomas, Haily Sain, Lalah Mclaughlin, Lindsey Spohr, Greg Degirolamo, Anne R. Schutte

UCARE: Research Products

The study examined the effects of executive attention on spatial working memory in adults using a location recall task. Attention is suggested to play a crucial role in maintenance of a remembered location in spatial working memory. Awh and Jonides (2001) found that reaction times to a presented stimulus were faster when the stimulus was held in spatial working memory. A subsequent study found that when holding a location in spatial working memory, tasks which shift attention cause memory performance to be worse for the remembered location. An ERP study by Awh and Jonides (2001) found similar response amplitudes between …

Intertemporal Similarity: Discounting As A Last Resort, Jeffrey R. Stevens

Jeffrey Stevens Publications

Standard models of intertemporal choice assume that individuals discount future payoffs by integrating reward amounts and time delays to generate a discounted value. Alternative models propose that, rather than integrate across them, individuals compare within attributes (amounts and delays) to determine if differences in one attribute outweigh differences in another attribute. For instance, Leland (2002) and Rubinstein (2003) propose models that 1) compare the two reward amounts to determine whether they are similar, 2) compare the similarity of the two time delays, and then 3) make a decision based on these similarity judgments. Here, I tested discounting models against attribute-based …

The Domain Specificity Of Intertemporal Choice In Pinyon Jays, Jeffrey R. Stevens, Bryce Kennedy, Dina Morales, Marianna Burks

Jeffrey Stevens Publications

When choosing between a piece of cake now versus a slimmer waistline in the future, many of us have difficulty with self-control. Food-caching species, however, regularly hide food for later recovery, sometimes waiting months before retrieving their caches. It remains unclear whether these long-term choices generalize outside of the caching domain. We hypothesized that the ability to save for the future is a general tendency that cuts across different situations. To test this hypothesis, we measured and experimentally manipulated caching to evaluate its relationship with operant measures of self-control in pinyon jays (Gymnorhinus cyanocephalus). We found no correlation …

Measuring Older Adult Confidence In The Courts And Law Enforcement, Joseph A. Hamm, Lindsey E. Wylie, Eve M. Brank

Department of Psychology: Faculty Publications

Older adults are an increasingly relevant subpopulation for criminal justice policy but, as yet, are largely neglected in the relevant research. The current research addresses this by reporting on a psychometric evaluation of a measure of older adults’ Confidence in Legal Institutions (CLI). Confirmatory factor analysis (CFA) provided support for the unidimensionality and reliability of the measures. In addition, participants’ CLI was related to cynicism, trust in government, dispositional trust, age, and education, but not income or gender. The results provide support for the measures of confidence in the courts and law enforcement, so we present the scale as a …

Development And Validation Of A State-Based Measure Of Emotion Dysregulation: The State Difficulties In Emotion Regulation Scale (S-Ders), Jason M. Lavender, Matthew T. Tull, David Dilillo, Terri Messman-Moore, Kim L. Gratz

Department of Psychology: Faculty Publications

Existing measures of emotion dysregulation typically assess dispositional tendencies and are therefore not well suited for study designs that require repeated assessments over brief intervals. The aim of this study was to develop and validate a state-based multidimensional measure of emotion dysregulation. Psychometric properties of the State Difficulties in Emotion Regulation Scale (S-DERS) were examined in a large representative community sample of young adult women drawn from four sites (N = 484). Exploratory factor analysis suggested a four-factor solution, with results supporting the internal consistency, construct validity, and predictive validity of the total scale and the four subscales: Nonacceptance (i.e., …

Response Bias On Self-Report Measures Of Sexual Fantasies Among Sexual Offenders, Kindra Seifert, Jenna Boulas, Matthew T. Huss, Mario J. Scalora

Department of Psychology: Faculty Publications

The impact of sexual fantasies in future risk and treatment response among sexual offenders has long been known. However, as we develop objective self-report measures of sexual fantasies, response bias is becoming an increasing concern. In examining a sample of institutionalized sex offenders, the present study suggests that offenders’ responses on these measures are prone to response bias, the bias does not negate their associations with other self-report measures of sexual deviance, and relationship of their sexual fantasies does not appear to relate to actual behavioral indications. Clinical and research implications for these findings are discussed.

The Impact Of Treatment Exposure, Trauma, And Caregiver Involvement In Therapy On Children's Response To Behavioral Treatment, Mindy R. Chadwell

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

Early childhood represents a time period during of rapid growth and development including physical development, language and communication, autonomy, and a wide variety of self-regulation skills (Campbell, 2006; Egger & Angold, 2006). Children vary in the rates at which they achieve these skills and they may challenge their parents through behaviors such as noncompliance and temper tantrums (Butler & Eyberg, 2006). Failure for children to adequately develop these basic skills can contribute to the development of behavior problems that lead to persistent problems throughout life (Whittaker et al., 2011). This study examined three factors that influence young children’s response to …

Bugs Are Not Loved, David Bober

Nebraska College Preparatory Academy: Senior Capstone Projects

The story The Metamorphosis is about Gregor, a young salesman, who turns into a giant insect. Over the course of The Metamorphosis, Gregor slowly begins to hate his change more and more. During his change, he slowly separates from his family to the point where they are relieved when he dies. This story is important because the protagonists has clear ordeals with change and how it affects him. From the story, I learned that most change is often resented, and when change is pushed, it usually ends negatively.

Repeated Administration Of Aripiprazole Produces A Sensitization Effect In The Suppression Of Avoidance Responding And Phencyclidine-Induced Hyperlocomotion And Increases D2 Receptor-Mediated Behavioral Function, Jun Gao, Rongyin Qin, Ming Li

Department of Psychology: Faculty Publications

The present study investigated how repeated administration of aripiprazole (a novel antipsychotic drug) alters its behavioral effects in two behavioral tests of antipsychotic activity and whether this alteration is correlated with an increase in dopamine D₂ receptor function. Male adult Sprague-Dawley rats were first repeatedly tested with aripiprazole (3, 10 and 30 mg/kg, subcutaneously (sc)) or vehicle in a conditioned avoidance response (CAR) test or a phencyclidine (PCP) (3.20 mg/kg, sc)-induced hyperlocomotion test daily for five consecutive days. After 2–3 days of drug-free retraining or resting, all rats were then challenged with aripiprazole (1.5 or 3.0 mg/kg, sc). Repeated …

The Interplay Of Trait Anger, Childhood Physical Abuse, And Alcohol Consumption In Predicting Intimate Partner Aggression, Rosalita C. Maldonado, Laura E. Watkins, David Dilillo

Department of Psychology: Faculty Publications

The current study examined three well-established risk factors for intimate partner aggression (IPA) within Finkel and Eckhardt’s I³ model, including two impellance factors—trait anger and childhood physical abuse history—and the disinhibiting factor of alcohol consumption. Participants were 236 male and female college students in a committed heterosexual dating relationship who completed a battery of self-report measures assessing childhood physical abuse, trait anger, alcohol consumption, and IPA perpetration. Results revealed a significant three-way interaction showing that as the disinhibition factor alcohol consumption increased, the interaction of the two impelling factors, trait anger and childhood physical abuse, became increasingly more positive. …

Evolutionary Pressures On Primate Intertemporal Choice, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

From finding food to choosing mates, animals must make intertemporal choices that involve fitness benefits available at different times. Species vary dramatically in their willingness to wait for delayed rewards. Why does this variation across species exist? An adaptive approach to intertemporal choice suggests that time preferences should reflect the temporal problems faced in a species' environment. Here, I use phylogenetic regression to test whether allometric factors (relating to body size), relative brain size, and social group size predict how long 13 primate species will wait in laboratory intertemporal choice tasks. Controlling for phylogeny, a composite allometric factor that includes …

Long-Lasting Sensitization Induced By Repeated Risperidone Treatment In Adolescent Sprague-Dawley Rats: A Possible D2 Receptor Mediated Phenomenon?, Jing Qiao, Jun Gao, Qing Shu, Qinglin Zhang, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Rationale Risperidone use in children and adolescents for the treatment of various neuropsychiatric disorders (e.g., schizophrenia, autism, disruptive behavior, etc.) has increased substantially in recent decades. However, its long-term effect on the brain and behavioral functions is not well understood. Objective The present study investigated how a short-term risperidone treatment in adolescence impacts antipsychotic response in adulthood in the conditioned avoidance response and phencyclidine (PCP)-induced hyperlocomotion tests. Methods Male adolescent Sprague-Dawley rats (postnatal days [P] 40–44 or 43–48) were first treated with risperidone (0.3, 0.5, or 1.0 mg/kg, subcutaneously (sc)) and tested in the conditioned avoidance or PCP (3.2 mg/kg, …

The Cognitive Underpinnings Of Bias In Forensic Mental Health Evaluations, Tess M. S. Neal, Thomas Grisso

University of Nebraska Public Policy Center: Publications

We integrate multiple domains of psychological science to identify, better understand, and manage the effects of subtle but powerful biases in forensic mental health assessment. This topic is ripe for discussion, as research evidence that challenges our objectivity and credibility garners increased attention both within and outside of psychology. We begin by defining bias and provide rich examples from the judgment and decision-making literature as they might apply to forensic assessment tasks. The cognitive biases we review can help us explain common problems in interpretation and judgment that confront forensic examiners. This leads us to ask (and attempt to answer) …

Not Just Welfare Over Justice: Ethics In Forensic Consultation, Philip J. Candilis, Tess M. S. Neal

University of Nebraska Public Policy Center: Publications

The ethics of forensic professionalism is often couched in terms of competing individual and societal values. Indeed, the welfare of individuals is often secondary to the requirements of society, especially given the public nature of courts of law, forensic hospitals, jails, and prisons. We explore the weaknesses of this dichotomous approach to forensic ethics, offering an analysis of Psychology’s historical narrative especially relevant to the national security and correctional settings. We contend that a richer, more robust ethical analysis is available if practitioners consider the multiple perspectives in the forensic encounter, and acknowledge the multiple influences of personal, professional, and …
