The Effect Of Peer Presence On Adolescent Risk-Taking Behaviors, Kelly E. Daniel

Honors College Theses

The emergence of risk-taking in adolescence, which can have life altering implications such as teenage pregnancy, car accidents, or drug overdoses, has been attributed to several different aspects of development including increased reward sensitivity and immature cognitive control contingent on motivation. Recent psychological research also indicates that adolescent risk-taking increases in the presence of peers. It remains unclear, however, whether this peer effect on risk-taking is attributable to amplified reward sensitivity or is a more general effect of experimenter expectancy and social desirability. This study builds upon this research using a computerized risk-taking task with stimuli that illustrate the probabilities …

Schadenfreude, The Dark Triad, And The Effect Of Music On Emotion, Robin Lane

Honors College Theses

Schadenfreude is a humorous response at the misfortune of others and has been suggested to be an empathic defense mechanism. Previous research indicates that individuals who tend to exhibit the Dark Triad personality traits narcissism, psychopathy, and Machiavellianism, experience higher levels of Schadenfreude. Additional studies suggest that music modulates neural activity associated with experiencing humor. In the present study we ask, do music and dark personality traits influence Schadenfreude? Participants viewed a series of brief, randomly intermixed physical misfortune and neutral videos (e.g., a person falling off a treadmill or running on a treadmill, respectively), with either an upbeat or …

The Maternal Personhood Of Cattle And Plants At A Hindu Center In The United States, Daniel S. Capper

Faculty Publications

Religious experiences with sacred nonhuman natural beings considered to be “persons” remain only vaguely understood. This essay provides a measure of clarification by engendering a dialogue between psychoanalytic self psychology on one side and, on the other, religious experiences of cattle and Tulsi plants as holy mothers at a Hindu cattle sanctuary in the United States. Ethnographic data from the Hindu center uncover experiences of sacred maternal natural beings that are tensive, liminal, and colored with affective themes of nurturance, respect, and intimacy, much like psychoanalytic maternal selfobjects. Devotees protect cattle and ritually venerate plants because these actions facilitate a …

Groundhog Oracles And Their Forebears, Daniel S. Capper

Faculty Publications

Groundhog Day animal weather forecasting ceremonies continue to proliferate around the United States despite a lack of public confidence in the oracles. This essay probes religio-historical and original ethnographic perspectives to offer a psychological argument for why these ceremonies exist. Employing Paul Shepard’s notion of a felt loss of sacred, intimate relationships with nonhuman nature, as well as Peter Homans’ concept of the monument that enables mourning, this essay argues that groundhog oracles serve as monuments that allow humans experientially to attempt to heal lost sacred relationships with animals like weather forecasting bears, hedgehogs, and badgers

No Association Between Current Depression And Latent Toxoplasmosis In Adults, Bruce L. Brown, Shawn D. Gale, Andrew N. Berrett, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Changes in behaviour and cognition have been associated with latent infection from the apicomplexan protozoan Toxoplasma gondii (Nicolle et Manceaux, 1908) in both animal and human studies. Further, neuropsychiatric disorders such as schizophrenia have also been associated with latent toxoplasmosis. Previously, we found no association between T. gondii immunoglobulin G antibody (IgG) seropositivity and depression in human adults between the ages of 20 and 39 years (n = 1 846) in a sample representative of the United States collected by the Centers for Disease Control as part of a National Health and Nutrition Examination Survey (NHANES) from three datasets collected …

How Can We Build A Moral Robot?, Kristen E. Clark

Capstones

Artificial intelligence is already starting to drive our cars and make choices that affect the world economy. One day soon, we’ll have robots that can take care of our sick and elderly, and even rescue us in rescue us in emergencies. But as robots start to make decisions that matter—it’s raising questions that go far beyond engineering. We’re stating to think about ethics.

Bertram Malle and Matthias Scheutz are part of a team funded by the department of defense. It's their job to answer a question that seems straight out of a sci-fi novel: How can we build a moral …

Prescription For Critical Thinking: A Discussion Of Psychotropic Medication And Counseling, Barton W. Biggs

Educational Specialist, 2009-2019

This paper examines questions about the safety and efficacy of psychotropic medication, and looks at how these questions should impact the field of counseling. The paper first looks at increasing rates of use of psychotropic medication, and establishes that nearly every clinical mental health counselor will work with clients who are taking or considering taking such medication. The paper next examines the scientific literature and establishes that there is a legitimate basis for questions to be raised about the safety and efficacy of these medications. The paper goes on to establish that there is a foundation in ethical codes and …

Positive Parenting, Conduct Problems, And Callous-Unemotional Traits, Julia E. Clark

LSU New Orleans Theses and Dissertations

The current study tested the association of both positive and negative aspects of parenting with callous-unemotional (CU) traits and conduct problems. Caregivers of 92 kindergarteners were recruited to complete a series of survey measures. Overall, parent-report of negative parenting practices was not associated with teacher report of conduct problems. However, parent report of positive parenting practices (i.e., warmth, positive reinforcement, positive communication and cooperation) was negatively associated with conduct problems and CU traits. Interactions between positive parenting variables and CU traits in their association with conduct problems indicated that positive reinforcement related more strongly to lower levels of conduct problem …

Effects Of Pharmacological De-Prenylation Of Rhes On Motor Behavior In A Beta-Nitropropionic Acid Animal Model Of Huntington's Disease, Ashley Whitmarsh

LSU New Orleans Theses and Dissertations

Huntington’s disease (HD) is a heritable, neurodegenerative disorder characterized by motor, cognitive, and psychiatric disturbances. The progressive disease is caused by an unstable CAG expansion within the gene that normally encodes for the huntingtin protein (Htt). The expanded mutant form of Htt (mHtt) is expressed ubiquitously throughout patients’ bodies; however, neuronal degeneration is prominent only in the corpus striatum and, to a lesser extent, the cortex. The Ras homolog Rhes is also preferentially localized to the striatum. The putative co-factor Rhes has been shown to act with mHtt to cause neuronal death. Simvastatin, a lipid lowering drug, and zoledronate, a …

Fearful Temperament Moderates The Association Between Positive Parenting And Children's Social Competence During Early Childhood, Jessica M. Grande

LSU New Orleans Theses and Dissertations

Social competence during kindergarten has been linked to adaptive teacher-child and peer relationships. The quality of parents’ interaction with their children during the toddler years may promote better social development placing children on a trajectory towards social competence. Quite possibly, children vary in how responsive they are to parenting efforts. This study evaluated the extent to which positive parenting predicted change in social competence from child age 3 to 4 among 137 parent-child dyads. Observational measures of positive parenting and fearful temperament were analyzed when children were 3-years of age. Teacher reports of social competence in the classroom were collected …

Emotional And Autonomic Responding To Auditory Stimuli, Jeremy C. Peres

LSU New Orleans Theses and Dissertations

Much of the research examining emotion induction, regulation, and suppression considers solely the visual modality (e.g., pictures of faces) for emotion elicitation. In reality, emotions are cued, expressed, and interpreted through multiple modalities by employing the extensive use of auditory stimuli in addition to visual stimuli. There have been some recent efforts to offset this imbalance in modality preference by using emotional auditory stimuli alone or in addition to visual stimuli. This project aims to further investigate emotional and autonomic responding to auditory stimuli with the added component of examining differential responding across social (nonlinguistic vocal expression) and non-social auditory …

The Relationship Between Elevation, Connectedness, And Compassionate Love In Meaningful Films, Sophie Janicke, Mary Beth Oliver

Communication Faculty Articles and Research

Expanding on the research of meaningful entertainment media and its effects, this study investigated the relationship between experiences related to elevation responses to film. Whereas research thus far has focused primarily on portrayals of altruism to elicit elevation, the results of this study show that portrayals of connectedness, love, and kindness in meaningful films are also able to elicit feelings of elevation. Moreover, elevation mediated the relationship between meaningful films and feelings of connectedness towards the transcendent, close others and toward one’s family; compassionate love towards close others; and compassionate motivation to love and be good to humanity. The study …

Incentive Contrast As A Relative Reward, Alexandra Schmidt

Honors Projects

This study examines the relationship between rapid relative reward comparisons and incentive contrast among rats (n=5). Animals were trained to lever-press in order to obtain access to a sucrose solution (concentration used: 1%, 10% or 20% in tap water). These rewards were placed outside an operant box which could be reached through a small hole displaying sessions with mixed comparisons (1v20%, 20v1%) or single sessions (1v1%, 10v10%, 20v20%) that rotated between two spouts containing the pre-randomized order of paired blocks; allowing for comparative analysis between two spouts/concentrations and blocks of responses. Throughout weekly testing each animal experienced a …

Effects Of Repeated Quetiapine Treatment On Conditioned Avoidance Responding In Rats, Jun Gao, Min Feng, Natashia Swalve, Collin Davis, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

The present study characterized the behavioral mechanisms of avoidance–disruptive effect of quetiapine in the conditioned avoidance response test under two behavioral testing (2 warning signals vs. 1 warning signal) and two drug administration conditions (subcutaneous vs. intravenous). In Experiments 1 and 2, well-trained adult male Sprague-Dawley rats were tested under the subcutaneous (s.c.) quetiapine treatment (5.0, 15.0, 25.0, 50.0 mg/kg) for 7 days in a novel procedure consisting of two conditioned stimuli (CS) (white noise serving as CS1 and pure tone as CS2). Only the highest dose (50.0 mg/kg) produced a persistent suppression of the avoidance response without impairing the …

The Use Of Peer Mentoring To Decrease Stress In Student Registered Nurse Anesthetists, Elise G. Head

Doctoral Projects

Nurse anesthesia programs throughout the nation are extremely competitive with strict admissions criteria and demanding curriculum. Students enrolled in these programs, termed Student Registered Nurse Anesthetists (SRNAs), experience high average daily stress levels throughout their enrollment in a nurse anesthesia program (NAP). This quantitative study examined whether there is a decrease in SRNA average daily perceived stress when peer mentoring is employed. Inclusion criterion was all SRNAs enrolled in a single 3 year, post-baccalaureate Doctor of Nursing Practice (DNP) NAP at a comprehensive Carnegie research university with Southern Regional Education Board-Level 1 designation. Fifty-six SRNAs were surveyed using a modified …

Coyotes On The Web: Understanding Human-Coyote Interaction And Online Education Using Citizen Science, Zuriel Anne Rasmussen

Dissertations and Theses

Coyote (Canis latrans) numbers are increasing in urban areas, leading to more frequent human-coyote interactions. Rarely, and particularly when coyotes have become habituated to humans, conflicts occur. Effective education about urban coyotes and how to prevent habituation reduces conflict. Citizen science, in the form of online education, can be used to engage and educate city dwellers about urban coyotes. In this research, I explore Portland Metropolitan Area (PMA) residents' baseline experiences with, and attitudes toward, urban coyotes. Next, I investigate citizen science as a tool for education. Using the Portland Urban Coyote Project (PUCP), a citizen science project, as a …

Exploring Acceptance Of Using An Online Platform To Teach Parents Of Children With Autism Methods In Applied Behavior Analysis (Aba), Marwah S. Zagzoug

Seton Hall University Dissertations and Theses (ETDs)

Background and Purpose of the Study: A diagnosis of autism can lead to lifelong struggles for parents and children. These families face profound difficulties in coping with stress while seeking out early interventions and managing imperative service needs. Parents are increasingly turning to the internet for information, advice, and even formal training. Breakthroughs in technology have made the internet more accessible and more sophisticated. The involvement of parents in applying intervention strategies to help their autistic children has long been advocated as a useful approach. Enabling parents as interventionists provides renewed confidence and reduced stress for parents as well as …

Training A New Trick Using No-Reward Markers: Effects On Dogs’ Performance And Stress Behaviors, Naomi Rotenberg

Theses and Dissertations

This study explored using no-reward markers (NRMs). Dogs were taught a novel trick. In the IG group dogs’ errors were ignored; in the NRM group they elicited a tone. Performance and stress were evaluated. IG dogs reached higher levels of performance, with no difference in the frequency of stress behaviors.

Comparing Rapid Scene Categorization Of Aerial And Terrestrial Views: A New Perspective On Scene Gist, Lester C. Loschky, Ryan V. Ringer, Katrina Ellis, Bruce C. Hansen

Psychology Faculty Publications

Scene gist, a viewer's holistic representation of a scene from a single eye fixation, has been extensively studied for terrestrial views, but not for aerial views. We compared rapid scene categorization of both views in three experiments to determine the degree to which diagnostic information is view dependent versus view independent. We found large differences in observers' ability to rapidly categorize aerial and terrestrial scene views, consistent with the idea that scene gist recognition is viewpoint dependent. In addition, computational modeling showed that training models on one view (aerial or terrestrial) led to poor performance on the other view, thereby …

The Effects Of Size And Principal Axis Difference Ratio On The Use Of Featural And Geometric Cues, Spencer J. Price

Honors College Theses

Enclosure size has been shown to affect an animal’s reliance on featural and geometric cues when reorienting in space. Previous research has shown that humans and animals rely primarily on geometric cues in smaller enclosures, and on featural cues in larger enclosures. The multiple-bearings hypothesis predicts that directional information is more discriminable than distance information when landmarks are father away from a goal. As the size of the environment increased, the distance information was less discernible than featural information. In the current study, we tested to see if the reliance on geometry changes across enclosure size. Three different Principal Axis …

Aesthetics And Performance Evaluation Of Post-Industrial Public Parks, Adel C. Vaughn

Landscape Architecture Undergraduate Honors Theses

Post-Industrial sites are often un-utilized and deserted places that are an aesthetic, social, ecological, and physical hindrance to the realm of the cities in which they lie, however they possess enormous potential. With respectful and transformative design, these new public parks gain a variety of benefits that extend well beyond the typical benefits exhibited by public parks due to their rich history, fascinating existing structures, high levels of visual and sensorial stimulation, one-of-a-kind traits, and opportunity for impactful change. By evaluating these post-industrial public parks, knowledge can be gained about what specific elements in the landscape contribute to their overall …

Consequences Of Repeated Ethanol Exposure During Early Or Late Adolescence On Conditioned Taste Aversions In Rats, Jessica Saalfield, Linda Spear

Psychology Faculty Scholarship

Alcohol use is prevalent during adolescence, yet little is known about possible long-lasting consequences. Recent evidence suggests that adolescents are less sensitive than adults to ethanol's aversive effects, an insensitivity that may be retained into adulthood after repeated adolescent ethanol exposure. This study assessed whether intermittent ethanol exposure during early or late adolescence (early-AIE or late-AIE, respectively) would affect ethanol conditioned taste aversions 2 days (CTA1) and >3 weeks (CTA2) post-exposure using supersaccharin and saline as conditioning stimuli (CS), respectively. Pair-housed male Sprague-Dawley rats received 4 g/kg i.g. ethanol (25%) or water every 48 h from postnatal day (P) 25-45 …

A Culturally-Sensitive Model Of The Development Of Child Anxiety., Jenny Marie Petrie

Electronic Theses and Dissertations

Explanatory models significantly enhance the understanding of etiological influences that place children at risk for anxiety, yet little is known about processes that promote resilient outcomes in children. While contextual factors influence risk and protective processes, cultural constructs have not been incorporated into existing models of anxiety and the role of culture remains obscure. The current study proposes a culturally sensitive model for understanding the etiological and mitigating processes underlying anxious symptoms in ethnic minority youth, and preliminarily tests basic components of the proposed model within a non-clinical community sample of 49 African American (AA) parent-child dyads who completed self-report …

Dialectical Behavior Therapy And Adolescent Patient Treatment Dropout, Danessa Mayo

Loma Linda University Electronic Theses, Dissertations & Projects

Attrition in mental health treatment is an area of concern among the adolescent population, especially with patients engaged in deliberate self-harm. The purpose of this study was to examine the treatment attrition rate for adolescents with deliberate self-harm in an adapted dialectical behavior therapy intensive outpatient program. A total of 141 adolescents previously enrolled in the program were available for the study. Results demonstrated a 31.9% dropout rate. Graduates indicated greater improvement of overall distress from baseline to post-treatment than dropouts. Dropouts attended an average of 12 treatment sessions. Several factors were examined to identify potential predictors of patient treatment …

The Role Of Stress In Hypersexual Behavior, Randy Gilliland

Theses and Dissertations

The proposed diagnostic criteria for Hypersexual Disorder included "[r]epetitively engaging in sexual fantasies, urges, or behaviors in response to stressful life events" (Kafka, 2010, p.279) as a symptom, although no data demonstrates a causal relationship between stress and hypersexual behavior. We sought to confirm previous findings while furthering the field's understanding of this relationship by being the first study to assess stress and hypersexual behavior across multiple time points. Specifically, we sought to test three hypotheses within a sample of men seeking treatment for hypersexual behavior: 1) hypersexual individuals report higher stress levels than published norm samples; 2) stress predicts …

Short-Term Effects Of A Western Diet On The Number Of Brainderived Neurotrophic Factor Immunoreactive Neurons In The Hypothalamic Arcuate, Ventromedial And Paraventricular Nuclei, Kaitlyn Elizabeth Gilland

Open Access Theses

Brain-derived neurotrophic factor (BDNF) is an important anorexogenic factor and has been shown to be involved in obesity. It is important to know when changes in BDNF expression occur to possibly prevent development of dietary obesity. BDNF mRNA decreases in response to long-term western diet (WD) exposure in the ventromedial hypothalamus (VMH), yet no study has investigated the short-term effects of WD on BDNF expression in the hypothalamus. It was hypothesized BDNF protein would mirror a decrease in BDNF mRNA in the VMH when mice were fasted for 48-hours or fed WD for 6-hours, 48-hours, 1-week and 3-week and decrease …

Effects Of Amphetamine On Striatal Dopamine Release, Open-Field Activity, And Play In Fischer 344 And Sprague–Dawley Rats, Stephen M. Siviy, Lana S. Mcdowell, Samantha R. Eck, Alexandra Turano, Garnik Akopian, John P. Walsh

Psychology Faculty Publications

Previous work from our laboratories has shown that juvenile Fischer 344 (F344) rats are less playful than other strains and also appear to be compromised in dopamine (DA) functioning. To determine whether the dysfunctional play in this strain is associated with deficits in the handling and delivery of vesicular DA, the following experiments assessed the extent to which F344 rats are differentially sensitive to the effects of amphetamine. When exposed to amphetamine, striatal slices obtained from F344 rats showed a small increase in unstimulated DA release when compared with slices from Sprague–Dawley rats; they also showed a more rapid high …

Executive Dysfunction Is Predictive Of Clinical Symptomatology In 22q11.2 Deletion Syndrome, Chinonyere Kemdirim Bello

Loma Linda University Electronic Theses, Dissertations & Projects

By adulthood, 25%- 30% of individuals with 22q11.2 deletion syndrome (22qDS) develop a psychotic disorder, often schizophrenia, and it is not understood why. Given the known genetic etiology of this disorder and the greatly elevated risk for development of schizophrenia, this group offers the possibility of defining a seemingly homogenous maturational pathway to psychosis. Neurocognitive deficits have been increasingly recognized as an important dimension of schizophrenia, particularly in the executive domain. Thus, we assessed multiple aspects of executive cognition in 22qDS, in order to: 1) characterize performance across this domain as compared to age-matched healthy controls; and 2) determine whether …

An Evaluation Of The Validity Of A Script-Driven Imagery Procedure Among Traumatic Event Exposed Adolescents, Emily Renae Mischel

Graduate Theses and Dissertations

Extensive research suggests script-driven imagery procedures employed with traumatic event-exposed adults produce reliable reactions that map onto contemporary models of posttraumatic stress, including increased physiological (Carson et al., 2000; Orr et al., 1998; Ramón et al., 2006) and negative affective (Pitman et al., 1987) responses to trauma scripts. Therefore, such procedures can be utilized in a controlled, laboratory-based setting, supporting mechanism-oriented research designed to better understand the nature, correlates, and consequences of traumatization and posttraumatic stress symptoms (PTSS). Unfortunately, only one study has begun to evaluate the validity of script-driven imagery procedures for use with youth, making further investigation of …
