Examining The Effect Of Medical Risk, Parental Stress, And Self-Efficacy On Parent Behaviors And The Home Environment Of Premature Children, Kathryn Woods

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

The purpose of this study was to examine the relationship between medical risk and parenting stress and the extent to which parental self-efficacy moderates the relationship between medical risk, parenting stress, specific parenting behaviors (i.e., parental responsivity, acceptance of child, parental involvement) and the home environment (i.e., organization of environment, learning materials, variety in experience, and IT-HOME total score) of premature children. Participants included 72 parent-child dyads with premature children between the ages of 7 and 35 months corrected age. Measures included parent reports of medical risk, stress, self-efficacy, and the IT-HOME. Results show that medical risk was not significantly …

Time Course Of Prepulse Inhibition Disruption Induced By Dopamine Agonists And Nmda Antagonists: Effects Of Drug Administration Regimen, Ming Li, Wei He, Jing Chen

Department of Psychology: Faculty Publications

Prepulse inhibition (PPI) of acoustic startle response is impaired in patients with schizophrenia and in animals acutely treated with dopamine agonists and NMDA antagonists. In this study, we investigated the time course of PPI disruption induced by repeated amphetamine, quinpirole, phencyclidine (PCP), and dizocilpine (MK-801) treatment. We focused on how PPI disruption development was influenced by drug administration regimens, comparing a constant versus an escalating dosing regimen. Male Sprague–Dawley rats were repeatedly treated with amphetamine (1.25–5.0 mg/kg, or constant 5.0 mg/kg, sc), PCP (0.50–2.0 mg/kg, or constant 0.5, 1.0 or 2.0 mg/kg, sc), quinpirole (0.03–0.12 mg/kg, or constant 0.12 mg/kg, …

Interpersonal Aggression Perpetration: Static And Emotion Regulation Risk Factors, Jill Panuzio

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious public health problem for both men and women in the United States. With aspirations of alleviating the significant negative effects of IPA, a substantial body of literature has been devoted to uncovering risk factors for IPA perpetration. Much of this research has focused on static, or relatively stable, factors that may influence IPA, such as life stress, distress tolerance, rumination, and jealousy. However, considering situational variables that influence individuals more proximally to aggressive acts, in conjunction with these static factors, may provide more precise prediction of partner aggression. Current theoretical and empirical work …

The Cumulative Impact Of Sexual Revictimization On Emotion Regulation Difficulties: An Examination Of Female Inmates, Kate Walsh, David K. Dilillo, Mario J. Scalora

Department of Psychology: Faculty Publications

The present study examined associations between child sexual abuse (CSA), adult sexual victimization, and emotion regulation difficulties in a sample of 168 incarcerated women. Approximately 50% of the participants reported CSA, 54% reported adult sexual victimization, and 38% reported sexual revictimization (i.e., CSA and adult victimization). Revictimized women reported significantly greater difficulties with several facets of emotion regulation when compared to singly victimized and nonvictimized women. Interestingly, singly victimized women did not demonstrate greater emotion regulation deficits when compared to nonvictims. Findings suggest that the negative impact of victimization experiences on adult emotion regulation abilities may be cumulative. Furthermore, they …

Initial Mlu Predicts The Relative Efficacy Of Two Grammatical Treatments In Preschoolers With Specific Language Impairments, Paul J. Yoder, Dennis L. Molfese, Elizabeth Gardner

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Purpose—We sought to confirm predictions based on past findings that pre-treatment mean length of utterance (MLU) would predict which of two grammatical treatments would best facilitate generalized and maintained grammatical development in preschoolers with specific language impairment (SLI).

Method—The participants were 57 preschoolers with specific language impairment (SLI). A randomized group experiment was used. The two grammatical treatments were Broad Target Recasts (BTR) and Milieu Language Teaching (MLT). MLU was assessed at Time 1 in two conversational language samples. Growth rate of productive grammar was quantified using growth curve modeling on the Index of Productive Syntax (IPSyn) from …

The Development Of Future Orientation: Underpinnings And Related Constructs, Sarah J. Beal

Department of Psychology: Dissertations, Theses, and Student Research

Future orientation has been conceptualized in a variety of ways across literatures in psychology, sociology, education, and vocation. The lack of a shared definition and measurement across theoretical perspectives has resulted in a challenge in comparing findings across literatures and organizing results in a way that provides a coherent sense of how future orientation impacts later outcomes. Trommsdorff (1979) provided a comprehensive definition of future orientation that included eight dimensions: extension, detail, domain, affect, motivation, control, sequence of events, and number of cognitions. Study 1 was designed to test this definition using measures from five prominent theories of future orientation …

Visual Attention And Social Anxiety: Oculomotor Behavior When Threatened, Jacqueline S. Singh

Department of Psychology: Dissertations, Theses, and Student Research

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study addressed some inconsistencies and gaps in the literature using eye tracking methodology. Participants with high and low trait social anxiety were randomly assigned to either give a speech or to watch a video of another individual delivering a speech (state social anxiety manipulation). Next, participants were asked to engage in a free view task in which pairs of emotional facial stimuli (angry-happy, angry-neutral, or happy-neutral) were presented for 3 s. Eye movements were monitored …

Exploratory Analyses Of A Developmental Conceptualization Of Insight And Treatment Outcomes Of Individuals With Serious Mental Illness In Psychiatric Rehabilitation, Ashley R. Wynne

Department of Psychology: Dissertations, Theses, and Student Research

The purpose of the present study was to further examine the relationship between adolescent psychiatric pathology and SMI by assessing the relationship between prior mental health services before the age of 18 and time of assessment on people’s insight into their illnesses. A secondary relationship between adolescent psychiatric pathology and functioning in a variety of domains before, during, and after treatment was assessed. Overall, there was an inconsistent pattern of results and partial support of hypotheses. The current study was a retrospective longitudinal study in which assessments were given to 308 participants in an inpatient psychiatric rehabilitation unit every 6 …

Why Confronting Sexism Works: Applying Persuasion Theories To Confronting Sexism, Amy Hillard

Department of Psychology: Dissertations, Theses, and Student Research

Speaking up about or confronting prejudice creates more positive attitudes, but the mechanism underlying confrontation’s prejudice reducing effect remains unclear. Based on an integration of the confronting prejudice and persuasion literatures, I expected that observing a confrontation (vs. no confrontation) reduces prejudice and discrimination; that elaborating on confrontation messages reduces prejudice and discrimination more than confrontation alone; and that elaborating on confrontation messages causes attitude change that lasts longer than confrontation alone. Participants were recruited to complete measures of sexism and feelings toward subtypes of women across three time points (i.e., pre-test, lab manipulation, and post-test). During the lab manipulation, …

When Knowing Just Isn't Enough: Examining The Role Of Moral Emotions In Health Decision Making Using The Theory Of Planned Behavior, Kate Duangdao

Department of Psychology: Dissertations, Theses, and Student Research

A proposed integrated Theory of Planned Behavior (TPB) model aimed to examine the role of moral emotions and two health outcomes: prosocial behaviors and smoking outcomes. Based on Tangney’s work with shame and guilt-proneness, it was expected that those more prone to guilt would engage in more prosocial behaviors and those more prone to shame would engage in more smoking behaviors. Prosocial behaviors were found to be negatively associated with smoking outcomes. However, results suggested that guilt and shame-proneness seem to function similarly in predicting behavioral outcomes. Components within the TPB were generally positively correlated with each health outcome, however …

Interictal Magnetoencephalographic Findings Related With Surgical Outcomes In Lesional And Nonlesional Neocortical Epilepsy, Rui Zhang, Ting Wu, Yingying Wang, Hongyi Liu, Yuanjie Zou, Wen Liu, Jing Xiang, Chaoyong Xiao, Lu Yang, Zhen Fu

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Purpose: To investigate whether interictal magnetoencephalography (MEG) concordant with other techniques can predict surgical outcome in patients with lesional and nonlesional refractory neocortical epilepsy (NE).

Methods: 23 Patients with lesional NE and 20 patients with nonlesional NE were studied. MEG was recorded for all patients with a 275 channel whole-head system. Synthetic aperture magnetometry (SAM) with excess kurtosis (g2) and conventional Equivalent Current Dipole (ECD) were used for MEG data analysis. 27 Patients underwent long-term extraoperative intracranial video electroencephalography (iVEEG) monitoring. Surgical outcomes were assessed based on more than 1-year of post-surgical follow-up using Engel classification system.

Results: As we …

Time Course Of The Attenuation Effect Of Repeated Antipsychotic Treatment On Prepulse Inhibition Disruption Induced By Repeated Phencyclidine Treatment, Ming Li, Erik He, Nick Volf

Department of Psychology: Faculty Publications

Antagonism of prepulse inhibition (PPI) deficits produced by psychotomimetic drugs has been widely used as an effective tool for the study of the mechanisms of antipsychotic action and identifying potential antipsychotic drugs. Many studies have relied on the acute effect of a single administration of antipsychotics, whereas patients with schizophrenia are treated chronically with antipsychotic drugs. The clinical relevance of acute antipsychotic effect in this model is still an open question. In this study, we investigated the time course of repeated antipsychotic treatment on persistent PPI deficit induced by repeated phencyclidine (PCP) treatment. After a baseline test with saline, male …

Child/Adolescent Sexual Abuse And Alcohol: Proposed Pathways To Problematic Drinking In College Via Ptsd Symptoms, Emotion Dysregulation, And Dissociative Tendencies, Alicia K. Klanecky

Department of Psychology: Dissertations, Theses, and Student Research

Research has discussed the use of alcohol to self-medicate posttraumatic stress (PTSD) symptoms following child/adolescent sexual abuse (CASA). Less research has examined the self-medication hypothesis in college students. Further, investigation of the self-medication hypothesis generally precludes the integration of additional psychological vulnerabilities that may impact students’ alcohol consumption. Supported by the “dynamic” stress-diathesis perspective, emotion regulation (ER) difficulties and insufficient dissociative tendencies existing prior to and potentially altered after CASA exposure may relate to problematic alcohol use. The current study aimed to provide an initial, cross-sectional examination of 1) the relations between CASA exposure severity and alcohol use, 2) the …

Interventions For Families Victimized By Child Sexual Abuse: Clinical Issues And Approaches For Child Advocacy Center-Based Services, Poonam Tavkar, David J. Hansen

Department of Psychology: Faculty Publications

Child sexual abuse poses serious mental health risks, not only to child victims but also to non-offending family members. As the impact of child sexual abuse is heterogeneous, varied mental health interventions should be available in order to ensure that effective and individualized treatments are implemented. Treatment modalities for child victims and non-offending family members are identified and described. The benefits of providing on-site mental health services at Child Advocacy Centers to better triage and provide care are discussed through a description of an existing Child Advocacy Center-based treatment program. Recommendations for research and clinical practice are provided.

Reassessing The Architecture Of The Health Beliefs Models In Low-Income Diverse Families, Krista B. Highland

Department of Psychology: Dissertations, Theses, and Student Research

Health beliefs contribute to health outcomes. These health beliefs extend to include health beliefs parents have regarding their children’s health. However, the role of parental health beliefs remains unexplored among a low-income population. This study aims to assess these beliefs and the effects they have on child health. Furthermore, this study aims to delineate potential belief differences between socioecological-level groups (e.g. population density, Latino identification, and insurance coverage). The long-term goal is to understand the relationships among various personal health beliefs and parental health beliefs, psychosocial factors, community factors, cultural factors, organizational factors, and healthcare perceptions among this at-risk population. …

The Good, The Bad, And The Rare: Memory For Partners In Social Interactions, Jenny Volstorf, Jörg Rieskamp, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

For cooperation to evolve via direct reciprocity, individuals must track their partners’ behavior to avoid exploitation. With increasing size of the interaction group, however, memory becomes error prone. To decrease memory effort, people could categorize partners into types, distinguishing cooperators and cheaters. We explored two ways in which people might preferentially track one partner type: remember cheaters or remember the rare type in the population. We assigned participants to one of three interaction groups which differed in the proportion of computer partners’ types (defectors rare, equal proportion, or cooperators rare). We extended research on both hypotheses in two ways. First, …

Participants completed performance and agility testing at the onset and end of the program. Lastly, participants completed cognitive …

Spatial Discounting Of Food And Social Rewards In Guppies (Poecilia Reticulata), Nelly Mühlhoff, Jeffrey R. Stevens, Simon M. Reader

Department of Psychology: Faculty Publications

In temporal discounting, animals trade off the time to obtain a reward against the quality of a reward, choosing between a smaller reward available sooner versus a larger reward available later. Similar discounting can apply over space, when animals choose between smaller and closer versus larger and more distant rewards. Most studies of temporal and spatial discounting in non-human animals use food as the reward, and it is not established whether animals trade off other preferred stimuli in similar ways. Here, we offered female guppies (Poecilia reticulata) a spatial discounting task in which we measured preferences for a larger reward …

Neuromagnetic Measures Of Word Processing In Bilinguals And Monolinguals, Yingying Wang, Jing Xiang, Jennifer Vannest, Tom Holroyd, Daria Narmoneva, Paul Horn, Yinhong Liu, Douglas Rose, Ton Degrauw, Scott Holland

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Objective: This study aimed to use magnetoencephalography (MEG) to examine the question of whether Mandarin-English bilingual speakers recruit the same cortical areas or develop distinct language-specific networks without overlaps for word processing.

Methods: Eight healthy Mandarin-English bilingual adults and eight healthy English monolingual adults were scanned while single-word paradigms were audio-visually presented.

Results: Our results showed significantly stronger beta-band power suppression in the right inferior parietal lobe (IPL) covering the supramarginal gyrus (BA 40) and angular gyrus (BA 39) for bilinguals when processing Mandarin versus English. Moreover, there were no significant differences between bilinguals and monolinguals in the left inferior …

The Traumatic Stress Response In Child Maltreatment And Resultant Neuropsychological Effects, Kathryn R. Wilson, David J. Hansen, Ming Li

Department of Psychology: Faculty Publications

Child maltreatment is a pervasive problem in our society that has long-term detrimental consequences to the development of the affected child such as future brain growth and functioning. In this paper, we surveyed empirical evidence on the neuropsychological effects of child maltreatment, with a special emphasis on emotional, behavioral, and cognitive process–response difficulties experienced by maltreated children. The alteration of the biochemical stress response system in the brain that changes an individual’s ability to respond efficiently and efficaciously to future stressors is conceptualized as the traumatic stress response. Vulnerable brain regions include the hypothalamic–pituitary–adrenal axis, the amygdala, the hippocampus, and …

Olanzapine And Risperidone Disrupt Conditioned Avoidance Responding By Selectively Weakening Motivational Salience Of Conditioned Stimulus: Further Evidence, Chen Zhang, Yiru Fang, Ming Li

Department of Psychology: Faculty Publications

Suppression of conditioned avoidance response is a preclinical behavioral index of antipsychotic activity. Previous work shows that olanzapine and risperidone disrupt avoidance response elicited by a less salient conditioned stimulus (CS2) to a greater extent than avoidance elicited by a more salient stimulus (CS1), suggesting that antipsychotic drugs may have a weakening action on motivational salience of stimuli. In the present study, we further examined this mechanism of antipsychotic action, focusing on the possible impact of baseline difference of CS1 and CS2 response rates on the avoidance-disruptive effect of olanzapine and risperidone. Rats were first trained to acquire avoidance responding …

Sleep Assessments In Healthy School-Aged Children Using Actigraphy: Concordance With Polysomnography, Karen Spruyt, David Gozal, Ehab Dayyat, Adrienne Roman, Dennis L. Molfese

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Actigraphic recordings (ACT) are widely used in school children as a less intrusive and more extended approach to evaluation of sleep problems. However, critical assessment of the validity and reliability of ACT against overnight polysomnography (NPSG) are unavailable. Thus, we explored the degree of concordance between NPSG and ACT in school-aged children to delineate potential ACT boundaries when interpreting pediatric sleep. Non-dominant wrist ACT was simultaneously recorded with NPSG in 149 healthy school-aged children (4.1 to 8.8 years old, 41.7% boys and 80.4% Caucasian) recruited from the community. Analyses were limited to the Actiware (MiniMitter-64) calculated parameters originating from 1-min …

Policy And Practice: An Analysis Of The Implementation Of Supported Employment In Nebraska, Heng-Hsian N. Liu

Department of Psychology: Dissertations, Theses, and Student Research

Supported employment (SE) is an evidence-based practice (EBP) for persons with severe mental illness (SMI) aimed at competitive employment. SE has a large evidence base, demonstrating outcomes across settings and populations. SE has been promoted by the Centers for Medicare and Medicaid Services (in the U.S. Department of Health and Human Services) and widely disseminated through the internet via a “community tool-kit” sponsored by the Substance Abuse and Mental Health Services Administration.

The SE literature expresses the opinion that state governments can successfully implement SE. Researchers have developed implementation guidelines and identified stages of statewide implementation; however, most SE implementation …

Juror Perceptions Of Juveniles Transferred To Criminal Court: The Role Of Generic Prejudice And Emotion In Determinations Of Guilt, Megan Beringer Jones

Department of Psychology: Dissertations, Theses, and Student Research

Research examining juror perceptions of juveniles tried as adults has provided mixed results, with some studies providing evidence of bias against juveniles tried as adults, and others finding no evidence of this bias. The present research aimed to clarify this issue by examining the roles of generic prejudice and emotion in jurors’ judgments of juveniles tried as adults. Study 1 assessed which stereotypes people associate with juveniles tried as adults compared to juveniles tried in juvenile court and adults tried in criminal court. Study 2 examined to what extent angry, fearful, sad, and neutral mock jurors used these stereotypes to …

Sleep Duration, Sleep Regularity, Body Weight, And Metabolic Homeostasis In School-Aged Children, Karen Spruyt, Dennis L. Molfese, David Gozal

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

OBJECTIVE: The goal was to explore the effects of duration and regularity of sleep schedules on BMI and the impact on metabolic regulation in children.

METHODS: Sleep patterns of 308 community-recruited children 4 to 10 years of age were assessed with wrist actigraphs for 1 week in a cross-sectional study, along with BMI assessment. Fasting morning plasma levels of glucose, insulin, lipids, and high-sensitivity C-reactive protein also were measured for a subsample.

RESULTS: Children slept 8 hours per night, on average, regardless of their weight categorization. A nonlinear trend between sleep and weight emerged. For obese children, …

Multiple “Hits” During Postnatal And Early Adulthood Periods Disrupt The Normal Development Of Sensorimotor Gating Ability In Rats, Jing Chen, Zucheng Wang, Ming Li

Department of Psychology: Faculty Publications

In the present study, we evaluated a multiple-hit animal model of schizophrenia in an attempt to capture the complex interactions among various adverse developmental factors in schizophrenia. Sprague–Dawley rats were assigned to receive either repeated daily 3-h maternal separation for eight days (first “hit”) on postnatal days (PND) 3 to 10, and/or avoidance conditioning for six days (second “hit”) on PND 49–56, and/or repeated phencyclidine treatment (third “hit”, 3.0 mg/kg, sc) immediately after each daily avoidance conditioning. Prepulse inhibition (PPI) of acoustic startle reflex was assessed at late adolescence (PND 41–43) and early adulthood (PND 62–63). The change in %PPI …

Heterogeneity Of Individuals With A History Of Child Sexual Abuse: An Examination Of Children Presenting To Treatment, C. Thresa Yancey, David J. Hansen, Karen Z. Naufel

Department of Psychology: Faculty Publications

The current study examined children and families who presented for treatment through Project SAFE (Sexual Abuse Family Education) following childhood sexual abuse. Pretreatment assessment data were used to develop clusters of participants with significantly differing presentation of symptom outcome following abuse. Four clusters were discovered: (a) a Highly Distressed group, whose members had clinically elevated scores on all self- and parent-report measures; (b) a Problem Behaviors group, whose members had scores within the normal range for self-report measures and elevated scores on all parent-report measures; (c) a Subclinical group, whose participants had scores below the mean and below cutoff scores …

To Google Or Not To Google: Graduate Students’ Use Of The Internet To Access Personal Information About Clients, David K. Dilillo, Emily B. Gale

Department of Psychology: Faculty Publications

The emergence of Internet search and social media sites now permits therapists to obtain a plethora of personal information about their clients online. These behaviors raise a number of ethical issues related to client privacy, self-determination, and informed consent. The purpose of this study is to examine student therapists’ opinions and behaviors in regard to the use these websites to search for information about their clients. A national sample of 854 psychology doctoral students was surveyed in regard to their online activities, attitudes, and frequency of searching for client information online. Results showed that Internet usage is pervasive in this …

Cognitive-Behavioral Therapy For Immigrants Presenting With Social Anxiety Disorder: Two Case Studies, Brandon J. Weiss, J. Suzanne Singh, Debra Anne Hope

Department of Psychology: Faculty Publications

Cognitive-behavioral therapy (CBT) for the treatment of social anxiety disorder (SAD) has demonstrated efficacy in numerous randomized trials. However, few studies specifically examine the applicability of such treatment for ethnic minority clients. Thus, the purpose of this article is to present two case studies examining the utility of individualized CBT for SAD with two clients who immigrated to the United States, one from Central America and one from China, for whom English was not the primary language. Both clients demonstrated improvement on a semistructured interview and self-report measures. Necessary adaptations were modest, suggesting that therapy could be conducted in a …
