A Quantitative Analysis Of The Value-Enhancing Effects Of Nicotine, Bupropion, And Varenicline In Male And Female Rats, Scott Barrett

Department of Psychology: Dissertations, Theses, and Student Research

Smoking and tobacco dependence are serious health concerns in the United States and globally. Reward via the pharmacological effects of nicotine are believed to be the principal motivating factor that drive tobacco dependence. Research reveals differences in sensitivity between males and females to the motivational effects of nicotine in tobacco use. Enhancement of reinforcement value of non-nicotine rewards contributes to overall nicotine reward. Similar value-enhancing effects have been observed by the two most commonly prescribed smoking cessation aids, bupropion and varenicline. The present dissertation investigated the value-enhancing effects of nicotine, bupropion and varenicline in both male and female rats using …

Differentiating Disclosure And Concealment In Measurement Of Outness For Sexual Minorities: The Nebraska Outness Scale, Peter C. Meidlinger, Debra A. Hope

Department of Psychology: Faculty Publications

Research on lesbian, gay, and bisexual (LGB) individuals has long examined outness, or openness about one’s sexual orientation, as an important predictor of health and well-being. The authors reconceptualized outness as a composite of two related but independent constructs: disclosure and concealment of sexual orientation. This conceptualization guided creation of the Nebraska Outness Scale (NOS), a 10-item measure with a concealment (NOS-C) and disclosure (NOS-D) subscale. The scale and subscales showed good internal reliability, discriminant, convergent, and predictive validity. As hypothesized, concealment showed a stronger relationship to mental health and well-being constructs than disclosure. Disclosure, but not concealment, also differed …

Borderline Personality Disorder And Self-Conscious Emotions In Response To Adult Unwanted Sexual Experiences, Michelle Schoenleber, Kim L. Gratz, Terri Messman-Moore, David Dilillo

Department of Psychology: Faculty Publications

Borderline personality disorder (BPD) is associated with a proneness to unpleasant self-conscious emotions (SCE). Given that BPD is also associated with heightened rates of SCE-eliciting events (including unwanted sexual experiences), research examining the factors influencing SCE in response to these events is needed. This study examined associations between BPD pathology and SCE in response to adult unwanted sexual experiences among 303 community women. Extent of sharing about and perceived personal responsibility for the event were examined as moderators of the association between BPD and current event-related SCE. Both self-reported BPD symptom severity in the full sample and interview-based measures of …

Dimensional Structure Of Dsm-5 Posttraumatic Stress Symptoms: Support For A Hybrid Anhedonia And Externalizing Behaviors Model, Cherie Armour, Jack Tsai, Tory A. Durham, Ruby Charak, Tracey L. Biehn, Jon D. Elhai, Robert H. Pietrzak

Department of Psychology: Faculty Publications

Several revisions to the symptom clusters of posttraumatic stress disorder (PTSD) have been made in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Central to the focus of this study was the revision of PTSD's tripartite structure in DSM-IV into four symptom clusters in DSM-5. Emerging confirmatory factor analytic (CFA) studies have suggested that DSM-5 PTSD symptoms may be best represented by one of two 6-factor models: (1) an Externalizing Behaviors model characterized by a factor which combines the irritability/anger and self-destructive/reckless behavior items; and (2) an Anhedonia model characterized by items of loss of …

Climate Change Survey Measures: Exploring Perceived Bias And Question Interpretation, Tarik Abdel-Monem, Lisa M. Pytlikzillig, Tonya K. Bernadt, Nicole Wall

Lisa PytlikZillig Publications

Climate change has become an important yet politically divisive topic in recent years. Further complicating the issue are assertions that climate change– related public opinion surveys used by social scientists are biased or otherwise problematic. We conducted a pilot study to explore questions concerning bias and interpretation of climate change surveys. Our study sample was composed of adult residents of Nebraska (n = 115). We augmented our survey findings with cognitive interviews of a subsample of respondents (n = 20). We assessed study participants’ attitudes about climate change, and perceptions of bias and interpretation of survey questions drawn from previously …

Differential Effects Of Intermittent Versus Continuous Haloperidol Treatment Throughout Adolescence On Haloperidol Sensitization And Social Behavior In Adulthood, Jun Gao, Ming Li

Department of Psychology: Faculty Publications

Animal work on the behavioral effects of antipsychotic treatment suggests that different dosing regimens could affect drug sensitivity differently, with an intermittent treatment regimen tending to cause a sensitization effect, while a continuous treatment causing a tolerance. In this study, we explored how haloperidol (HAL) sensitization induced throughout adolescence and tested in adulthood was differentially impacted by these two dosing regimens in the conditioned avoidance response (CAR) test.We also examined howthese two dosing regiments affected social interaction and social memory in adulthood. Male adolescent Sprague-Dawley rats were treated with HAL via either osmotic minipump(HAL-0.25 CONT; 0.25mgkg⁻¹ day⁻¹, …

The Clinical Psychology Training Program At The University Of Nebraska–Lincoln, David J. Hansen, Timothy D. Nelson, David Dilillo, Debra A. Hope

Department of Psychology: Faculty Publications

The Clinical Psychology Training Program (CPTP) at the University of Nebraska–Lincoln (UNL) has been continuously accredited by the American Psychological Association (APA) since 1948, the first year any programs were accredited. The CPTP’s history and approach to training through the years have been described in numerous articles (DiLillo & McChargue, 2007; Hargrove, 1991; Hargrove & Howe, 1981; Hargrove & Spaulding, 1988; Hope, Hansen, & Cole, 1994; Howe, 1974; Howe & Neimeyer, 1979; Jones & Levine, 1963; Rivers & Cole, 1976). Our program was historically described as a “Community-Clinical” psychology training program, and this focus on understanding and enhancing well-being at …

Botulinum Toxin-Induced Facial Muscle Paralysis Affects Amygdala Responses To The Perception Of Emotional Expressions: Preliminary Findings From An A-B-A Design, M. Justin Kim, Maital Neta, F. Caroline Davis, Erika J. Ruberry, Diana Dinescu, Tood F. Heatherton, Mitchell A. Scotland, Paul J. Whalen

Department of Psychology: Faculty Publications

Background: It has long been suggested that feedback signals from facial muscles influence emotional experience. The recent surge in use of botulinum toxin (BTX) to induce temporary muscle paralysis offers a unique opportunity to directly test this “facial feedback hypothesis.” Previous research shows that the lack of facial muscle feedback due to BTX-induced paralysis influences subjective reports of emotional experience, as well as brain activity associated with the imitation of emotional facial expressions. However, it remains to be seen whether facial muscle paralysis affects brain activity, especially the amygdala, which is known to be responsive to the perception of …

Asenapine Sensitization From Adolescence To Adulthood And Its Potential Molecular Basis, Qing Shu, Rongyin Qin, Yingzhu Chen, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Asenapine is a new antipsychotic drug that induces a long-lasting behavioral sensitization in adult rats. The present study investigated the developmental impacts of adolescent asenapine treatment on drug sensitivity and on 3 proteins implicated in the action of antipsychotic drugs (i.e. Brainderived neurotrophic factor (BDNF), dopamine D₂ receptor, and ΔFosB) in adulthood. Male adolescent Sprague-Dawley rats (postnatal days, P 43-48) were first treated with asenapine (0.05, 0.10 or 0.20 mg/kg, sc) and tested in the conditioned avoidance or PCP (2.0 mg/kg, sc)-induced hyperlocomotion tasks for 5 days. After they became adults (∼P 76), asenapine sensitization was assessed in a …

The Reluctance Of African-Americans To Engage In Therapy, Monique Estelle Williamson

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

This thesis is presented with the intent to explore the reasoning behind why members of the African-American culture are reluctant to enter into therapy. While the numbers of African-Americans who enter therapy continue to rise there are still persistent stigmas that make therapy a taboo option for solving problems. The goal of this qualitative study is to identify (1) if there truly is reluctance in the African-American community, (2) why the African-American community is reluctant, (3) what are the stigmas regarding mental health and therapy from the perspectives of American participants, and (4) what would help break the barriers to …

A Micro-Level Analysis Of Behavioral Dynamics In Parent-Child Synchrony, Kadie L. Ausherman

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

This study investigates parent-child synchrony, a multilevel construct that has not been operationalized in a precise or standardized way. Synchrony is frequently discussed theoretically, yet there still lacks a clear means of measuring it, even on the behavioral level. When parent-child synchrony is operationalized in a study, it is rarely analyzed in such a way that reflects the dyadic dynamics that unfold as the parent and child are interacting. The aim of this study is to operationalize parent-child synchrony in terms of the dyadic behavior patterns. An overview of the current literature with regard to synchrony as a multilevel construct …

Effect Of Environmental Cues On Behavioral Efficacy Of Haloperidol, Olanzapine And Clozapine In Rats, Tao Sun, Xinfeng Liu, Ming Li

Department of Psychology: Faculty Publications

Previous studies have reported that context can powerfully modulate the inhibitory effect of an antipsychotic drug on phencyclidine (PCP)-induced hyperlocomotion (a behavioral test used to evaluate putative antipsychotic drugs). The present study investigated the experimental conditions under which environmental stimuli exert their influence through associative conditioning processes. Experiment 1 examined the extent to which prior antipsychotic treatment in the home cages affected a drug’s ability to inhibit PCP-induced hyperlocomotion in a novel motor activity test apparatus. Five days of repeated haloperidol (0.05 mg/kg, sc) and olanzapine (2.0 mg/kg, sc) treatment in the home cages still potentiated their inhibition of PCP-induced …

The Effect Of Yoga Lessons On Young Children's Executive Functioning, Heidi L. Beattie

Department of Psychology: Dissertations, Theses, and Student Research

Individual differences in preschool and school-aged children’s attention, inhibition and spatial working memory were examined after exposure to a yoga intervention. Previous research has found that exposure to yoga has improved attention in both adults and children. Previous research, however, is limited in regards to examining this relationship in a preschool-aged population. The purpose of the current study is to examine and compare the relationship between preschool-aged as well as school-aged children’s attention, inhibition, and spatial working memory abilities for children who participated in a yoga intervention and children who do not participate in a yoga intervention. Twenty-six 4 to …

Executive Control In Hispanic Children: Considering Linguistic And Sociocultural Factors, Miriam M. Martinez

Department of Psychology: Dissertations, Theses, and Student Research

Executive control represents a collection of high-order cognitive processes that are associated with important child outcomes, including academic achievement and social competencies. Despite the burgeoning interest in examining the development of executive control, less is known about the development of these skills among ethnic minority children. Hispanic children are currently the largest ethnic minority group in the United States and their diverse sociocultural and linguistic backgrounds provide an excellent context to study the influence of linguistic and sociocultural factors on the development of child executive control. The purpose of the three complementary studies reported in this dissertation is to contribute …

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. …

Parenting Behaviors, Adolescent Depressive Symptoms, And Problem Behavior: The Role Of Self-Esteem And School Adjustment Difficulties Among Chinese Adolescents, Cixin Wang, Yan Ruth Xia, Wenzhen Li, Stephan M. Wilson, Kevin Bush, Gary Peterson

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

Cross-sectional data from 589 Chinese adolescents were used to investigate whether parenting behaviors are directly or indirectly (through self-esteem and school adjustment difficulties) associated with adolescent depressive symptoms and problem behavior. Structural equation modeling results showed that school adjustment difficulties fully mediated the relations between two parenting behaviors (parental punitiveness and paternal monitoring) and adolescent problem behavior and partially mediated the relation between maternal monitoring and adolescent problem behavior. Adolescent self-esteem partially mediated the relations between maternal punitiveness and adolescent depressive symptoms and fully mediated the relations between parental support and adolescent depressive symptoms. Parental love withdrawal was not significantly …

Emerging From The Shadows: Civil War, Human Rights, And Peacebuilding Among Peasants And Indigenous Peoples In Colombia And Peru In The Late 20th And Early 21st Centuries, Charles A. Flowerday

Anthropology Department: Theses

Peacebuilding in Colombia and Peru following their late-20^th and early 21^st century civil wars is a challenging proposition. In this study, it becomes necessary as indigenous peoples and peasants resist domination by extractive industries and governments in their thrall. Whether they protest nonviolently or rebel in arms, they are targeted for human-rights violations, especially murder, disappearance and displacement. The armed actors, state, insurgency, paramilitaries or drug traffickers, destroy civic institutions (local or regional government) and the civil (nonprofit) sector and replace them with their own authoritarian versions. Therefore, peacebuilding has emphasized rebuilding civic institutions, civil society and local …

Yaya: Philippine Domestic Care Workers, The Children They Care For, And The Children They Leave Behind, Maria Rosario De Guzman

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

The domestic and care labor sector is integral to the economic and social fabric of almost every nation. Although there has been increasing attention to the plight and experiences of international migrant workers within this field, less is known about the experiences of rural-to-urban migrants employed in this same sector. This study focuses on “yayas”—domestic workers caring for children in affluent families in the Philippines and draws from fieldwork and interviews conducted in Quezon City. Participants were female “yayas” caring for young children while they themselves were separated from their own offspring, most of whom were left behind in their …

Adolescent Reactions To Maternal Responsiveness And Internalizing Symptomatology: A Daily Diary Investigation, Lisa Jobe-Shields, Gilbert R. Parra, Kelly E. Buckholdt, Rachel N. Tillery

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

A daily diary methodology was employed to gather teens’ perceptions of maternal responsiveness to daily stressful events and teens’ reactions to maternal responsiveness in a diverse sample (792 entries from 104 teens; 81% African American, mean age 13.7 years). Additionally, parents and teens completed baseline reports of internalizing symptoms. Diary findings were congruent with prior studies employing self-report measures of global maternal responses to emotion (e.g., higher probability of Accepting reactions to supportive responses, higher probabilities of Attack, Avoid-Withdraw reactions to non-supportive responses). Elevated baseline internalizing symptoms were related to perception of elevated Punish and Magnify responses during the week, …

Effects Of Alcohol Intoxication And Neurocognitive Processing On Intimate Partner Aggression, Rosalita C. Maldonado

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious public health concern that occurs with alarming frequency, results in both physical and psychological harm to victims, and costs billions of dollars per year due to healthcare costs and loss of productivity. These adverse consequences highlight the need to understand risk factors of IPA perpetration. Attempts to identify these risk factors have focused mostly on broad factors that may predispose someone to perpetrate aggression, including individual demographic and dispositional characteristics (e.g., low socioeconomic status, psychopathy). Although valuable, this knowledge cannot reveal the specific circumstances that may prompt an individual to perpetrate aggression against …

Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm

Department of Psychology: Dissertations, Theses, and Student Research

This dissertation investigates the role of trust in predicting cooperation with a natural resources management institution. It begins with an exploration of the legal landscape against which the relationship between land owners and natural resources management institutions is contextualized, presents a review of the often ostensibly disparate trust literature and a framework for its integration, and proposes and tests a model of trust and cooperation in the natural resources context. The results provide mixed support for the model as proposed but confirm the importance of trust in this context and suggest implications for policy, especially the potential importance of increasing …

Event-Related Potential Correlates Of Social And Nonsocial Cognitive Processes Related To Schizotypy, Charles A. Davidson

Department of Psychology: Dissertations, Theses, and Student Research

Social cognitive, neurocognitive, and social functioning research in serious mental illness (SMI) have recently proliferated. Their synergy requires translational bridges to applied research. This project aims to develop a measurement protocol capable of measuring independent components of social cognitive and neurocognitive brain functioning. These brain processes should each vary systematically with schizotypal traits whose extremes represent core elements of psychotic disorders. The measurement technology must be affordable, efficient, and acceptable for use in clinical settings.

An ERP protocol was developed that incorporates an array of candidate measures. The stimuli consist of emotional (angry and happy), neutral, and scrambled (non-face comparison) …

Supporting Positive Parent-Toddler Relationships And Reducing Toddler Tantrums: Evaluation Of Pcat-E, Tara M. Sjuts

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

At the most fundamental level, a positive parent-child relationship is the foundation of child success. However, the toddler period may present difficulties for the parent-child relationship. As toddlers explore their autonomy, they challenge parents with noncompliance and temper tantrums, which may be difficult for the parent-child relationship. This study examined the impact of an extension of Parent-Child Attunement Therapy (Parent Child Attunement Therapy – Enhanced; PCAT-E) on parenting behaviors, toddler tantrum behaviors, and the parent-toddler relationship. This extension featured eight individual didactic and coaching sessions with parent-child dyads focused on teaching positive parenting skills, effective commands, and emotion language modeling. …

Students' Perceptions Of Recess: An Examination Of Predictors Of Peer Conflict, Kadie Dooley

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

Recess plays an important role in students’ school days because it provides students opportunities to interact with their peers in unstructured settings. Some research has explored the relation between peer conflict within school contexts and how it is related to locations of positive play and the presence of adult supervisors. Further, researchers have conducted studies to examine within group differences for gender and grade, as well as between school differences. However, results have been mixed.

This dissertation examined the degree to which the following variables were related to where peer conflict occurs during recess: location of adult supervisors, location of …

Antioxidant Gene Therapy Against Neuronal Cell Death, Juliana Navarro-Yepes, Laura Zavala-Flores, Anandhan Annadurai, Fang Wang, Maciej Skotak, Namas Chandra, Ming Li, Aglaia Pappa, Daniel Martinez-Fong, Luz Maria Del Razo, Betzabet Quintanilla-Vega, Rodrigo Franco

Department of Psychology: Faculty Publications

Oxidative stress is a common hallmark of neuronal cell death associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, as well as brain stroke/ischemia and traumatic brain injury. Increased accumulation of reactive species of both oxygen (ROS) and nitrogen (RNS) has been implicated inmitochondrial dysfunction, energy impairment, alterations in metal homeostasis and accumulation of aggregated proteins observed in neurodegenerative disorders, which lead to the activation/modulation of cell death mechanisms that include apoptotic, necrotic and autophagic pathways. Thus, the design of novel antioxidant strategies to selectively target oxidative stress and redox imbalance might represent important therapeutic approaches against neurological disorders. …

Procedural Due Process In Modern Problem-Solving Courts: An Application Of The Asymmetric Immune Knowledge Hypothesis, Leah C. Georges

Department of Psychology: Dissertations, Theses, and Student Research

Problem-solving courts, such as drug and mental health courts, function under the model of therapeutic jurisprudence—the idea that legal policies and procedures should help and not harm clients, within the confines of the law (Winick & Wexler, 2002). Although it would seem that the lack of procedural due process in most problem-solving courts is in direct opposition to the best interests of a client, it is possible that observers find this more of a problem than do the court clients themselves. This two-experiment study applied Igou’s (2008) AIK hypothesis to problem-solving courts’ practice of sanctioning in the absence of due …

The Effects Of Alcohol Intoxication And Cognitive Emotion Regulation Strategies On Lab-Based Partner Aggression, Laura E. Watkins

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious national health concern that affects an alarming number of individuals and can lead to substantial psychological and physical suffering. Situational risk factors that arise in the immediate context of IPA reflect state-like influences that trigger aggression. Because these factors are more variable and fluctuate according to the situation, they are potentially promising targets for prevention and intervention efforts (e.g., through cognitive and behavioral interventions). Within this realm, two factors in particular appear to play a prominent role in the etiology of IPA: alcohol intoxication and cognitive emotion regulation strategies. In contrast to prior …

An Examination Of The Role Of Social Support, Coping Strategies, And Individual Characteristics In Students’ Adaptation To College, Arleen Bejerano

Department of Communication Studies: Dissertations, Theses, and Student Research

Adaptation, or adjustment, is a psycho-social process that occurs when an individual accepts and integrates into his or her life a transition from one situation to another situation (Schlossberg, 1981). Many individuals struggle with transitions because transitions involve changes in the environment, roles, routines, and/or ways of looking at the world. The present investigation examines the transition from high school to college, and explores the interpersonal and individual ways that students manage the changes accompanying this transition. Using Transition Theory as a framework, students’ social support networks, coping strategies, self-esteem, and depression are posited to influence students’ adaptation to college …

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 …

Parent Vs. Teacher Ratings Of Children’S Shyness As Predictors Of Language And Attention Skills, Kathleen Moritz Rudasill, Amanda Prokasky, Xiaoqing Tu, Scott R. Frohn, Kate Sirota, Victoria J. Molfese

Department of Educational Psychology: Faculty Publications

Shyness in childhood has been linked to multiple adjustment outcomes, including poor peer relations, internalizing problems, and clinical anxiety. However, shyness does not consistently emerge as a negative predictor of children’s success. This incongruity may stem, in part, from variations in the operationalization and measurement of shyness in different studies. Researchers often combine parent and teacher ratings of shyness, but correlations between parent and teacher reports are consistently small to medium. The purpose of this study is to examine parent and teacher ratings of shyness as they predict language and attention skills in preschool children, and explore discrepancies between parent …
