Is Talking Online To Unknown People Always Risky? Distinguishing Online Interaction Styles In A National Sample Of Youth Internet Users., Janis Wolak, David Finkelhor, Kimberly J. Mitchell

Sociology

Abstract

We examined the risk of unwanted online sexual solicitations and characteristics associated with four online interaction styles among youth Internet users. The interaction styles took into account the people with whom youth interacted online (people known in person only, unknown people met through face-to-face friends, unknown people met in chatroom, and other places online) and high- and low-risk patterns of online behavior. The aim was to provide a basis for identifying which youth may be most at risk from interacting online with unknown people.

The Effect Of Poverty On Child Development And Educational Outcomes, Patrice L. Engle, Maureen M. Black

Psychology and Child Development

Poverty affects a child’s development and educational outcomes beginning in the earliest years of life, both directly and indirectly through mediated, moderated, and transactional processes. School readiness, or the child’s ability to use and profit from school, has been recognized as playing a unique role in escape from poverty in the United States and increasingly in developing countries. It is a critical element but needs to be supported by many other components of a poverty alleviation strategy, such as improved opportunity structures and empowerment of families. The paper reviews evidence from interventions to improve school readiness of children in poverty, …

Stepping Up The Pressure: Arousal Can Be Associated With A Reduction In Male Aggression, Andrew Ward, T. Mann, E. H. Westling, J. D. Creswell, J. P. Ebert, Matthew Richard Wallaert , '05

Psychology Faculty Works

The attentional myopia model of behavioral control [Mann and Ward, 2007] was tested in an experiment investigating the relationship between physiological arousal and aggression. Drawing on previous work linking arousal and narrowed attentional focus, the model predicts that arousal will lead to behavior that is relatively disinhibited in situations in which promoting pressures to aggress are highly salient. In situations in which inhibitory pressures are more salient, the model predicts behavior that is relatively restrained. In the experiment, 81 male undergraduates delivered noise-blasts against a provoking confederate while experiencing either high or low levels of physiological arousal and, at the …

The Development Of Day-Night Differences In Sleep And Wakefulness In Norway Rats And The Effect Of Bilateral Enucleation, Andrew J. Gall, William D. Todd, Baisali Ray, Cassandra M. Coleman, Mark S. Blumberg

Faculty Publications

The suprachiasmatic nucleus (SCN) exhibits circadian rhythmicity in fetal and infant rats, but little is known about the consequences of this rhythmicity for infant behavior. Here, in Experiment 1, we measured sleep and wakefulness in rats during the day and night in postnatal day (P)2, P8, P15 and P21 subjects. As early as P2, day-night differences in sleep-wake activity were detected. Nocturnal wakefulness began to emerge around P15 and was reliably expressed by P21. We hypothesized that the process of photic entrainment over the first postnatal week, which depends upon the development of connectivity between the retinohypothalamic tract (RHT) and …

Ptsd Symptoms And Self-Rated Recovery Among Adult Sexual Assault Survivors: The Effects Of Traumatic Life Events And Psychosocial Variables, Cynthia J. Najdowski, Sarah E. Ullman

Psychology Faculty Scholarship

Prior research has demonstrated that self-blame is predictive of more PTSD symptoms and poorer recovery (Frazier, 2003; Koss, Figueredo, & Prince, 2002), and perceived control over recovery is associated with less distress (Frazier, 2003) in adult sexual assault (ASA) survivors. A structural equation model was tested to examine the role of traumatic events, self-blame, perceived control over recovery, and coping strategies on PTSD symptoms and self-rated recovery in women ASA survivors. Adaptive coping partially mediated the effects of other traumas, self-blame, and perceived control over recovery on PTSD symptoms, and showed a small positive association with increased PTSD symptoms. As …

Sustainability From The Perspectives Of Indigenous Leaders In The Bioregion Defined By The Pacific Salmon Runs Of North America, David Edward Hall

Dissertations and Theses

Extensive research suggests that the collective behavior of humanity is on an unsustainable path. As the evidence mounts and more people awaken to this reality, increased attention is being dedicated to the pursuit of answers for a just and sustainable future. This dissertation grew from the premise that effectively moving towards sustainability requires change at all levels of the dominant Western culture, including deeply held worldviews. The worldviews of many indigenous cultures offer alternative values and beliefs that can contribute to addressing the root causes of problems related to sustainability. In the bioregion defined by the Pacific Salmon runs of …

Day Length And Estradiol Affect Same-Sex Affiliative Behavior In The Female Meadow Vole, Annaliese K. Beery, Theresa J. Loo, Irving Zucker

Neuroscience: Faculty Publications

Non-sexual social bonding between adult mammals remains poorly understood, despite its importance in many species. Female meadow voles are territorial and nest alone in long summer day lengths when circulating estradiol concentrations are high, but cohabit in groups in short winter photoperiods when estradiol secretion is low. The influence of day length and estradiol on same-sex huddling behavior was assessed in adult female pairs housed together in long day lengths (LDs) or short day lengths (SDs) from weaning. The behavior of intact, ovariectomized, and estradiol-treated ovariectomized females from each photoperiod was assessed during 3 hour partner preference tests. Intact SD …

Supracutaneous Vibrotactile Perception Threshold At Various Non-Glabrous Body Loci, Miriam Bikah, M. Susan Hallbeck, John H. Flowers

Department of Psychology: Faculty Publications

Researchers at the University of Nebraska–Lincoln are currently designing a wearable/portable neutron detector. As an alerting mechanism, the device will transmit vibration to the wearer’s skin in the presence of hazardous levels of neutron radiation. The present study was designed to help in the ergonomically correct body placement of the neutron detection device while providing numerical values for vibratory thresholds at the surface of various non-glabrous body loci. The aim of the study was to investigate the underlying effects of locus stimulated, amount of subcutaneous fat around a specific body site and gender on low frequency vibration thresholds. Thirty-six participants, …

Mindfulness In Childbirth: An Investigation Of The Effects Of Mindfulness Training On Maternal Satisfaction With Childbirth And Obstetric Outcomes, Brenda L. Bratton

Dissertations

This study investigated the effects of mindfulness training on obstetric outcomes and maternal satisfaction with childbirth. We were interested in whether mindfulness training was more effective than a control group receiving psychoeducation on stress reduction. The goal of the intervention group was to increase participants' moment-to-moment awareness of thoughts, feelings, and body sensations during childbirth so that they would respond to these experiences rather than react to them in an automatic manner. These strategies were hypothesized to help a laboring woman minimize fear or anxiety associated with pain and complications and be more adaptive to whatever circumstances arose. Repeated measures …

Emotional Speech Corpus Construction, Annotation And Distribution, Brian Vaughan, Charlie Cullen, Spyros Kousidis, John Mcauley

Conference papers

This paper details a process of creating an emotional speech corpus by collecting natural emotional speech assets, analysisng and tagging them (for certain acoustic and linguistic features) and annotating them within an on-line database. The definition of specific metadata for use with an emotional speech corpus is crucial, in that poorly (or inaccurately) annotated assets are of little use in analysis. This problem is compounded by the lack of standardisation for speech corpora, particularly in relation to emotion content. The ISLE Metadata Initiative (IMDI) is the only cohesive attempt at corpus metadata standardisation performed thus far. Although not a comprehensive …

The Relationship Between Psychological Well-Being And Work Productivity: Validation Of The Oq Productivity Index, Vinessa Kaye Trotter

Theses and Dissertations

Managed Mental Health Care (MMHC) began blanketing the United States when cost of care rose exponentially. MMHC is one avenue many employers and insurance companies have chosen to provide employees with mental health treatment at controlled costs. However, not all employers view supplying their employees with mental health treatment beneficial, as they do not know mental health problems can significantly decrease work productivity. Brown and Jones (2005) used the Social Role Scale (SR) of the Severe Outcome Questionnaire (SOQ) to estimate work productivity in employees under the assumption that the scale measures work productivity. The purpose of this study was …

Predicting Behavior From Psychopathic And Antisocial Personality Traits In A Student Sample., Maryann Stone

Electronic Theses and Dissertations

Psychopathic personality is associated with a myriad of social and behavioral problems including violence, criminal activity, and overall failure to conform to social standards. In this study, psychopathic and antisocial personality traits are measured in a sample of college students via self-report surveys using questions derived from Hare's Psychopathic Checklist-Revised (PCL-R; 1991). Reliability and factor analyses were used to validate the inventory and create factor-based indices that were used to predict antisocial behavioral outcomes including violence, seeking revenge on persecutors, and suicidal ideation, in addition to other analogous and deviant behaviors. Findings showed a relationship between personality and behavior indicating …

Defining Acquaintance Rape: College Students' Perceptions Of Sexual Consent And Coercion, Sara Elizabeth Buck Doude

Dissertations

Perceptions of rape have evolved dramatically over the past decade. Prior to the second wave of the feminist movement, rape was perceived to be committed by a psychotic man against a woman. The feminist movement brought the term "acquaintance rape" into the popular lexicon and into the forefront of women's consciousness. As a result, throughout the 1970s and 1980s state governments enacted laws to prohibit "sexual assault," or expanded existing rape laws to include a variety of relationships or sexual acts. However, public perceptions of rape did not evolve as rapidly. Despite legislative efforts, there is no universally understood definition …

The Visual Perception Of Elasticity, Elizabeth Y. Wiesemann

Masters Theses & Specialist Projects

Two experiments were designed to evaluate human sensitivity to elasticity. Elastic objects bend when a force is applied to them. Observers saw two computer-generated bending rods (defined by the motions of 50 dots) on any given trial and were required to judge which rod was more flexible. Elasticity difference thresholds were calculated for each observer for each of three bending conditions. The rods bent in a plane that was either frontoparallel or oriented 42.5 or 85 degrees from frontoparallel. The results showed that observers could precisely discriminate between bending rods of different elasticities, independent of whether the bendings occurred in …

Effects Of Music On Emotional And Physiological Responses, Jenifer Fritz

Undergraduate Psychology Research Methods Journal

Past research has suggested that music with fast tempos and rhythms have different physiological and emotional effects than music with slow tempos and rhythms. If these beliefs and studies are accurate, an individual will have physiological changes and report different emotions and moods after listening to music, and these changes will depend on the style of music that was heard. Twenty-nine participants were asked to report current emotions, moods, and musical preferences before and after listening to one of four musical selections: rock, rap, classical, and no music. Emotion and mood state were not affected by any of the musical …

The Effectiveness Of A "None Of The Above" Answer Option In Multiple Choice Grammar Tests, Andrea Sides

Masters Theses & Specialist Projects

This study examines the use of "none of the above" (NOTA) as an answer option in a multiple-choice grammar test. Results from previous research on this topic have been mixed. Two forms of a grammar test, one without a NOTA option and one with a NOTA option, were developed and administered to a sample of 160 undergraduate students. Differences between the forms in item difficulty and discrimination were examined. Analysis revealed no differences in item discrimination or item difficulty between items without a NOTA option and items with a NOTA option. A discussion of the results, limitations, and suggestions for …

The Effects Of Attributional Style On Learning : Engagement As A Mediator, Courtney A. Hopkins

Theses, Dissertations and Culminating Projects

This study investigated the effects of attributional style on learning outcomes, with engagement in learning as a mediator. A model was developed to depict this relationship, suggesting that attributional style affects learning both directly and indirectly, with academic and civic engagement as a mediator between attributional style and learning. Hypothesis 1 stated that attributional style is related to academic performance, such that students with a positive attributional style will exhibit higher academic performance than students with a negative attributional style. Hypothesis 2 stated that engagement mediates the relationship between attributional style and academic performance. The data used in this study …

The Effect Of Computer-Based Biofeedback On Creativity, Qin Li

Renée Crown University Honors Thesis Projects - All

In recent decades, Psychology has advance empirical studies of creativity, aiming for a better and more concrete understanding of this elusive topic. One branch of these studies investigates creativity’s physiological manifestation in an attempt to isolate underlying neurophysiologic mechanisms involved in creative thinking. These studies, through EEG recording of electrical brain activity, indicated that highly creative individuals tend to express a low arousal state as compared to less creative individuals. This experiment investigates the relationship between induced low arousal and creativity. A computer-based biofeedback game is used to induce low arousal. A multivariate analysis of our data revealed no significant …

Eating Disorders: A Study Of University Type And Prevalence, Emily C. Riggins

Senior Honors Theses

Disordered eating has become an increasing problem, especially in western culture. A study was conducted to determine a possible relationship between disordered eating among college students and type of university. Previous studies allude to the possibility of private evangelical colleges yielding more eating disorders than private non-evangelical and public colleges. College students at two east coast universities were compared on the Eating Attitudes Test and a demographic questionnaire. The research indicated that prevalence of eating disorders is not significantly different between private evangelical institutions and private non-evangelical institutions. The findings show some background, prevalence, causes, and theoretical explanation of eating …

Season Of Birth Effects In Autism Spectrum Disorders, Kastley Marvin

Honors Scholar Theses

One factor that is investigated as a possible clue to etiological factors in Autism Spectrum Disorders (ASD) is season of birth. Season of birth effects could be the result of temperature, toxins, dietary changes, viral infections, and cultural or social factors that change seasonally (Bolton, Pickles, Harrington, Macdonald, & Rutter, 1992). A number of studies have looked for season of birth effects in ASD with no conclusive results. The current study analyzed season of birth effects in a sample of 441 children diagnosed with ASD. Analysis was also repeated after excluding prematurely born children from the data. Level of functioning …

The Influence Of Species And Context On Human-Dolphin Interactions, Deirdre Breen Yeater

Dissertations

Anthropogenic activities pose a threat to marine mammals around the world. Cetaceans that use coastal waters are at particular risk for potential disturbances caused by vessel traffic and human swimmers. Although many cetacean species are found near the coast of Utila, Honduras, little is known about their behavior or the effects of anthropogenic activities on their behavior. Whether the presence of boats and human swimmers led to short-term changes in dolphin behavior was investigated for three commonly sighted species of dolphins; rough-toothed (Steno bredanensis), spinner (Stenalla longirostris), and bottlenose (Turslops truncatus). The dolphins' behavioral activities, with and without other boats …

Childless Women In The Plays Of William Inge, Tennessee Williams, And Edward Albee, Suzanne Macdonald Winkel

Theses and Dissertations

This dissertation is an examination of three major twentieth-century American playwrights—William Inge, Tennessee Williams, Edward Albee—and their dramatic use of childless women characters in Come Back, Little Sheba (1950), Cat on a Hot Tin Roof (1955), and Who's Afraid of Virginia Woolf? (1962) respectively. Although the plays of Inge, Williams, and Albee have been analyzed individually by numerous scholars, they have not been studied together as works about procreation and childlessness. The study's historical focus is the post World War II era during which time the three plays proposed for analysis were written and produced. Commonly called the baby boom …

A Longitudinal Study Of Cortical Eeg Activity In Adolescents., Patrick Pössel, Hanna Lo, Anna Fritz, Simone Seemann

Faculty and Staff Scholarship

Background: The objective of this study is to test Davidson’s, and Heller and Nitschke’s models stating cortical activity in adolescents to be a marker for increased risk for depression.

Methods: Alpha activity was measured in 80 adolescents from medial-frontal (F3/4), lateral-frontal (F7/8), and medial-parietal (P3/4) electrodes, as well as self-reported depression and anxiety twice within 12 months. Stepwise hierarchical regression analyses with anxiety as covariate were calculated with alpha asymmetry as predicting variable and depression as target variable and vice versa.

Results: Independent of whether anxiety was used as covariate or not, frontal and parietal alpha asymmetry predict depression, but …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Attention-deficit/hyperactivity disorder (ADHD) is a common childhood disorder often treated by pediatricians or family practice physicians. ADHD knowledge held by treating physicians may be an important predictor in patient outcomes. This study examined ADHD knowledge and common assessment and treatment practices of pediatricians and family practice physicians via a national survey sent to members of the American Academy of Pediatrics and the American Academy of Family Physicians. Mailings included the Knowledge of Attention Deficit Disorders Scale--Revised (KADDS-R) and a demographic/practice questionnaire. Although both physician types reported utilizing assessment and treatment methods consistent with current ADHD practice guidelines, findings suggested that …

An Investigation Of The Ecology Of Nesting Golden Eagles In North Dakota, Anne Marguerite Coyle

Theses and Dissertations

Few studies have focused on golden eagles nesting in North Dakota. This project investigates the ecology of, and the potential effects from energy development on, nesting golden eagles in North Dakota, by collecting historical data, conducting nest checks and surveys (2002-2006).

Historical information was not sufficient for population estimates. Nest checks/surveys indicated that nest densities, occupied nest sites and territories was greatest near the riparian river bottoms. There were 176 potential extant territories. The average minimum distance between occupied nest sites was 6.32km (7.20km to 3.85km). The mean territory area was 8.95 km2 (SD = 4.25 km2, min = 3.09 …

The Impact Of Adolescent Social Anxiety On Adulthood Adjustment Among Sexually Abused Girls, Madeline Anne Rakow Ivanchenko

Master's Theses and Doctoral Dissertations

Childhood sexual abuse (CSA) is a significant social problem that has gained increased recognition since the 1980s. The increased attention has led to a substantial body of research that documents both the high prevalence and pervasive effects of CSA. CSA is associated with a wide range of adulthood psychopathology, including major depression, posttraumatic stress disorder, anxiety disorders, substance use, suicidal behavior, alterations in self-concept, and disruptions in interpersonal relatedness (Beichtman, Zucker, Hood, DaCosta & Cassavia, 1992; Browne & Finkelhor, 1986; Cole & Putnam, 1992; Polusny & Follette, 1995; Russell, 1986; Wilson, 2006). Sexually abused children are also at a higher …
