Students Sharing Feelings Of Grief: An Elementary Curriculum On Loss, Kristen Gloumakoff

Senior Honors Projects

“It is only natural that we and our children find many things that are hard to talk about. But anything human is mentionable and anything mentionable is manageable.The mentioning can be difficult, and the managing too, but both can be done if we’re surrounded by love and trust.” ~Fred Rogers This quote could be talking about many different things that parents find difficult to talk to their children about, such as smoking, drinking, drugs, divorce, and sex. I was introduced to this quote as a one about parents talking to their children about death. Death is a part of life, …

How Preference Plays A Role In Gender And Details, Jennifer Anstead, Brittni Martin

Undergraduate Psychology Research Methods Journal

How preference plays a role in gender and details was examined and evaluated in this experiment. We used Lindenwood University's Human Subject Pool to recruit 30 participants, 16 females and 14 males. Our purpose was to see whether the participants found more differences between the pairs of pictures they preferred over the less preferred pictures. We used gender stereotypical pictures with the hope that participants would prefer the picture that best fits their gender. We did not find statistical significance, F(2,58)=2.126, p=.129(p<.05), in that the participants discovered more differences in their preferred picture. However, we did find statistical significance between picture type and number correct, and the order the pictures were given and the number correct in each picture.

Children's Use Of Race In Drawing Inferences Based On Their Understanding Of Race Constancy, Casey A. Dawson

Masters Theses & Specialist Projects

Children’s understanding of race constancy and their subsequent use of race as a means of drawing inductive inferences were investigated. Race constancy was determined by children’s tendency to say that people could change category membership by changing their outside appearance. A second phase of the study measured how many race-based inferences children made relative to other social categories such as age or sex. The results indicated that children who had a better understanding of race constancy were also more likely to use race as a means of drawing inductive inferences. These findings support a developmental progression of race constancy and …

Beliefs Of Violence-Sensitive And Violence-Tolerant People, Amethyst Brell

Senior Honors Projects

Every person views the world through a different lens, and one can never fully understand the motivations and opinions of someone else. However, experiments and statistics can shed some light onto people’s thought patterns and behaviors. When horrific acts of violence occur, many people strive to understand why they happen. Through my study I hope to help solve some of the mysteries behind the different ways people interpret violence. I want to see why some people tend to be more sensitive to violence and why some are more tolerant of violence. I am doing this by building on previous research …

Corticospinal Excitability During A Perspective-Taking Task : Implications For Self Vs. Other Processing, Elizabeth M. Murray

Theses, Dissertations and Culminating Projects

Only by understanding the uniquely human ability to take a first- second- and third-person perspective, can we begin to elucidate the neural processes responsible for one’s inimitable conscious experience. The current study examined differences in hemispheric laterality during a first-person perspective (1PP) and third-person perspective (3PP) taking task, using Transcranial Magnetic Stimulation (TMS). Subjects were asked to take either the 1PP or 3PP in identifying the number of spheres in a virtual scene. During this task, single- pulse TMS was delivered to the motor cortex of both the left and right hemispheres of 10 healthy volunteers. Measures of TMS-induced motor-evoked …

Moral Emotion Regulation: The Case Of Abortion Attitudes, Steven Nydick

Renée Crown University Honors Thesis Projects - All

With regard to moral judgments. Lawrence Kohlberg claimed that reason and logic lead to answers about right and wrong. By contrast, Jonathan Haidt proposed an “emotivist” theory of morality in which feelings take center stage. I tested Haidt’s theory of moral judgment by showing 59 college undergraduate participants an abortion video while instructing them to increase, decrease, or make no attempt to change their level of emotion during the video. I found that the video succeeded at both increasing negative emotions (particularly disgust) and changing abortion attitudes to a more pro-life stance. Furthermore, the moral views of participants asked to …

The Influence Of Hunger On Attitudes: Does It Go Beyond Foods?, Euiyoung Kate Min

Renée Crown University Honors Thesis Projects - All

The purpose of this research was to investigate the influence of hunger on attitudes (self-reports and corresponding reaction times) toward foods and non-foods (people). Participants rated their attitudes toward pictures of foods and pictures of people (older and younger males and females) along several evaluative scales (global attitudes and attitudinal bases) while reaction times were recorded. This was done twice (once when hungry, once not), in sessions separated by one week. Consistent with previous research, hunger differentially impacted ratings of the information underlying attitudes. For example, for foods, ratings of negative affect information changed more as a function of hunger …

Nighttime Pedestrian Conspicuity: The Effects Of Pedestrian Movement, Orientation And The Configuration Of Retroreflective Material, Stacy Balk

All Theses

Most fatal collisions between vehicles and pedestrians occur at night; inadequate visibility is a key factor. Previous research has shown that positioning reflective markers on pedestrians in a manner that depicts biological motion greatly enhances conspicuity. This on-road experiment examined the conspicuity advantages of a full biological motion configuration relative to that provided by an ANSI class II safety vest. 120 healthy young participants were driven along a 3.5 mile route and pressed a button when they were confident they saw a pedestrian. A test pedestrian on the left shoulder of the roadway wore black clothing with either an ANSI …

The Effects Of Landmark Information On Navigation Performance, Attention To The Driving Environment, And Vehicle Control, Rachael Daniels

All Theses

Recent research has helped confirm that landmarks are used as strong navigational signals and assist with way-finding strategies. Current in-vehicle information systems however, use little information in the way of landmarks, and instead rely heavily on distance information in order to direct drivers to their destination. It has been suggested that our spatial knowledge of an environment rarely uses distance information accurately. Although, recent research has shown that landmarks are helpful, a deeper understanding of what specific types of landmarks help with navigation is lacking in the literature. The current study attempts to fill in this gap in the literature …

A Lakota/Nakota/Dakota Model Of Oratory, Cheryl A. Long Feather

Theses and Dissertations

Lakota/Nakota/Dakota people, as well as other Native American tribal groups, did not traditionally use the established, conventional forms of oration to which most in contemporary mainstream society relate. Rather, Native-specific epistemology, ontology and axiology played a central role in forming and supporting the function of communication as well as the speaking conventions that continue to be used today. These culturally-based patterns and structures present both challenges and opportunities that have been only marginally explored in various disciplines such as education, social and behavioral science, and psychology. This body of work exists for the purpose of exploring a traditionally Native understanding …

La Double Vie De Baudelaire: Le Trouble Bipolaire Et La Dépendance À L’Opium, Kristen Murphy

Senior Honors Projects

Charles Baudelaire (April 9th, 1821- August 31st,1867) the nineteenth century French poet, was an eccentric and scandalous character who pushed the boundaries of decency and literature quotidianly. Today he is considered the father of the modernist literary movements and is well respected in literary circles. However, during Baudelaire’s lifetime, his great work Les Fleurs du Mal (The Flowers of Evil) was censored by the French government, he was constantly bankrupt, attempted suicide once, and was an opium addict. Charles Baudelaire did not lead a cheerful life and his works show this darkness. In Les Fleurs du Mal, Baudelaire constantly refers …

The Media’S Influence In Everyday Life On Women’S Perception Of Body Image, Sarah Christian

Renée Crown University Honors Thesis Projects - All

Many women are not satisfied with their current body figures and frequently attempt to improve their figure. Body image discrepancies occur when a comparison between “actual” self to either “ought” or “ideal” selves don’t match up. If there is a difference between these two self-guides then a discrepancy exists. According to a national survey, half of women report negative evaluations of their appearance and worry about being or becoming overweight. One of the strongest socio-cultural pressures that women face with their body image is the media, such as magazines and television. Studies have shown that when exposed to thin body …

The Public Perception Of Enrichment For Captive Animals, Elizabeth Marie Webb

All Master's Theses

The effects of providing participants with educational information on enrichment as measured by the looking time at and ratings of zoo photographs were examined. One hundred and seventeen participants viewed photographs of zoo exhibits, 10 from each of the following categories: artificial exhibit with artificial enrichment, artificial exhibit with naturalistic enrichment, naturalistic exhibit with naturalistic enrichment, and naturalistic exhibit with artificial enrichment. Participants rated the photographs on exhibit aesthetic appeal, perceived animal happiness, and effectiveness of the enrichment. Pre- and posttest ratings of the importance of zoo roles were also collected. Results showed support for the hypothesis that participants provided …

The Relationships Among Interracial Friendship, Personality, And Racial Attitudes, Paula A. Suchy

Masters Theses and Doctoral Dissertations

Previous research indicates: that openness and agreeableness positively correlate with racial attitudes, and the importance of interracial friendship on reducing racial bias ( e.g.,Jackson & Poulsen, 2005). Hypotheses included: 1) individuals high on openness and/or agreeableness will report more positive racial attitudes, 2) positive racial attitudes will increase as the quantity and/or quality of interracial friendship increases, and 3) interracial friendship is a moderator between personality and racial attitudes. Participants (n = 217) completed an online survey containing the Big Five Inventory (2001 ), Brigham's ( 1993) Racial Attitudes Scale, a modified interracial contact questionnaire (Tropp and Pettigrew, 2005), Altemeyer's …

Child Sexual Abuse: Development Of Psychiatric Disorders And Interventions, Toshikazu Kuroda

Undergraduate Honors Capstone Projects

Child sexual abuse has become a serious social concern due to the recent report of its higher incidence rate than commonly believed. This form of child abuse has been proposed to bring about adverse effects on children's development since more than one century ago. However, research over past decades reveals that effects of sexual abuse are extremely complex and diverse. Particularly, there appear to be many unclear factors increasing the probability for the development of psychiatric disorders in sexually abused children. The present paper investigated how child sexual abuse creates diversity over the course of the victims' development from multiple …

Effects Of A Synthetic Cannabinoid On The Reinforcing Efficacy Of Ethanol In Rats, Ericka M. Bailey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The co-abuse of alcohol and marijuana is widespread, although the mechanisms underlying this behavior are unclear. There is some evidence of a relationship between the neural processes that mediate the effects of ethanol and marijuana. For example, research has shown that exposure to marijuana increases responding for, and intake of, ethanol. The alcohol deprivation effect is an anima l model of alcoholism that suggests that the reinforcing efficacy of ethanol, as measured by intake, increases following a period of deprivation. Recent research indicates that rats chronically exposed to marijuana during periods of alcohol deprivation consume ethanol above and beyond deprivation …

Student Teachers' Explicit And Implicit Perceptions Of Attention-Deficit/Hyperactivity Disorder, Hollie K. Berglof

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined student teachers' explicit and implicit perceptions of ADHD and the relationship between perceptions of ADHD and social desirability. In addition, the relationship between a current measure of implicit perceptions of ADHD and one that was adapted for this study was also investigated. Findings indicate that student teachers view a student portrayed as exhibiting symptoms consistent with ADHD more negatively than a "normal" child in terms of their self-reported first impressions of the child as well as their predictions for the child's future success. Participants' perceptions, as measured by two implicit measures, however, were mixed, with results from …

Psychosocial Variables And Their Relationship To Diabetic Outcome Among The Strong Heart Study Cohort, Brian D. O'Leary

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diabetes mellitus is one of the leading causes of death and disability in the United Sates. Certain Native American groups have been harder hit than the mainstream population, both in prevalence of the disease and in rates of related complications. The highest known prevalence in the world is found among a Southwestern U.S. Tribe, and other Native American Tribes have demonstrated similar prevalence rates. It has been shown that certain psychological factors such as depression and hostility impact both the occurrence and outcome of certain diseases, including diabetes.

This study examined whether those individuals who have not met the criteria …

The Temporal Relationship Between Environmental Factors And Psychological Symptoms In Native American Adolescents, Georgia Lee Matt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Native American youth often experience high rates of environmental risk factors that may put them at increased risk for developing psychological problems, yet research within this high-risk population is severely limited.

The present study was designed to provide information on the rate of psychological symptoms in a sample of Native American youth, and evaluate the impact of environmental factors (risk, protective, and cultural) on psychological disorder symptoms over time. Data were collected with a sample of Native American youth using the Youth Self Report, the Substance Abuse Subtle Screening Inventory–Adolescent 2, and a researcher-designed Biodemographic Questionnaire.

Findings indicate that clinically …

Germ-Line Chimerism And Paternal Care In Marmosets (Callithrix Kuhlii), C. N. Ross, Jeffrey French, G. Ortí

Psychology Faculty Publications

The formation of viable genetic chimeras in mammals through the transfer of cells between siblings in utero is rare. Using microsatellite DNA markers, we show here that chimerism in marmoset (Callithrix kuhlii) twins is not limited to blood-derived hematopoietic tissues as was previously described. All somatic tissue types sampled were found to be chimeric. Notably, chimerism was demonstrated to be present in germ-line tissues, an event never before documented as naturally occurring in a primate. In fact, we found that chimeric marmosets often transmit sibling alleles acquired in utero to their own offspring. Thus, an individual that contributes gametes to …

Tornar-Se Negro & Thinking Beautiful, Ayana Hosten

Independent Study Project (ISP) Collection

In 1990, the census reported that Brazilian’s population was 55.3 percent branco, 39.3 percent parda, 4.9 percent negro, and 0.5 percent Indio. In response to complaints that these racial identities were not sufficient, the IBEG conducted a survey where they asked people “Qual é sua cor?” This survey resulted in a list of 134 different racial identities that reflect the complexities of race in Brazil due to a history of miscegenation. At the two extremes of this racial spectrum is branco and negro. These two extremes have cultural and historical significance that I examine through scholarly research. In the field, …

The Question Of Animal Selves: Implications For Sociological Knowledge And Practice, Leslie Irvine

Anthropomorphism and Anthropocentrism Collection

The question of whether sociologists should investigate the subjective experience of non-human others arises regularly in discussions of research on animals. Recent criticism of this research agenda as speculative and therefore unproductive is examined and found wanting. Ample evidence indicates that animals have the capacity to see themselves as objects, which meets sociological criteria for selfhood. Resistance to this possibility highlights the discipline’s entrenched anthropocentrism rather than lack of evidence. Sociological study of the moral status of animals, based on the presence of the self, is warranted because our treatment of animals is connected with numerous “mainstream” sociological issues. As …

Gender Differences In Auditory Perception Of Pure Tone Frequencies And Speech Intelligibility Via Bone Conduction Transducers, Meghan Leigh Hodges

Master's Theses - Daytona Beach

Two experiments were conducted to see if gender differences exist in bone conduction hearing processes. The first experiment was a pure tone study where hearing thresholds for six pure tone frequencies and four bone conduction skull locations were measured in 15 male and 15 female participants to determine if gender differences exist in auditory signal detection. As frequency of the pure tone signal increased the difference between genders’ hearing thresholds and mean ranks of threshold overall; however, when Kruskal-Wallis statistical tests were performed, significant differences between genders for bone conduction were only found for the mastoid location at 6000-Hz and …

Peripheral Blood Perfusion Induced By Electrical Stimulation Of The Anterior Cingulate Cortex, Ji Wei He

Psychology Theses - Archive

In the last decade, much research has implicated the anterior cingulate cortex (ACC) in the modulation of both emotion and visceral functions in primates and rats. Rat studies have shown that electrical stimulation of the ACC suppresses animal’s behaviors associated with noxious stimuli, and inhibits spinal cord dorsal horn neuron activity induced by nociception in the periphery. Electrical stimulation of the periaqueductal grey (PAG) is reported to inhibit spinal cord dorsal horn neuron activity induced by nociception, while it generates dorsal root reflex (DRR). This is an important contributor to peripheral vasodilatation, i.e. leading to increased blood flow. The purpose …

Fluency In Pigeons: The Effects Of Response Rate On Learning, Matthew L. Porritt

Dissertations

Instructional procedures that build high response rates are purported to have significant benefits over procedures that do not focus on fast responding (Binder, 1996). However, much of the research exploring rate-building procedures is confounded by two variables: rate of reinforcement and number of exposures (Doughty, Chase, & O'Shields, 2004). In six experiments, the present study examined the effects of three variables, rate of reinforcement, number of exposures, and rate of responding, on learning under rate-building procedures in pigeons. In Experiment 1, rate-building produced significantly better learning outcomes when compared to a rate-controlled condition with number of exposures held constant. In …

Spatial Learning Deficit In The Hiv-1 Transgenic Rat: Discerning Place From Strategy Learning, Abigail Lashomb

Seton Hall University Dissertations and Theses (ETDs)

HIV -1 infection is associated with a constellation of cognitive and motor deficits collectively termed HIV associated dementia. With the onset of HAART treatment, these cognitive effects have become more mild, but also more prevalent. The lack of a proper animal model to study these cognitive effects of HIV has lead to the development of a new transgenic rat. This rat expresses the HIV -1 genome with functional tat and gp 120 viral proteins. These proteins are linked with direct neural toxicity as well as the induction of cytokines and other indirect means of neuronal damage. As part of the …

Perceptual Functions Of Perirhinal Cortex In Rats: Zero-Delay Object Recognition And Simultaneous Oddity Discriminations., Susan J Bartko, Boyer D Winters, Rosemary A Cowell, Lisa M Saksida, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

The perirhinal cortex (PRh) is widely accepted as having an important role in object recognition memory in humans and animals. Contrary to claims that PRh mediates declarative memory exclusively, previous evidence suggests that PRh has a role in the perceptual processing of complex objects. In the present study, we conducted an examination of the possible role of PRh in perceptual function in rats. We examined whether bilateral excitotoxic lesions of PRh or PPRh (perirhinal plus postrhinal cortices) in the rat would cause deficits in a zero-delay object-recognition task and a simultaneous oddity discrimination task. Both of these tasks measured spontaneous …

Individual Acoustic Variation In Fallow Deer (Dama Dama) Common And Harsh Groans: A Source-Filter Theory Perspective, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Mammals are able to distinguish conspecifics based on vocal cues, and the acoustic structure of mammal vocalizations is directly affected by the anatomy and action of the vocal apparatus. However, most studies investigating individual patterns in acoustic signals do not consider a vocal production-based perspective. In this study, we used the source-filter model of vocal production as a basis for investigating the acoustic variability of fallow deer groans. Using this approach, we quantified the potential of each acoustic component to carry information about individual identity. We also investigated if cues to individual identity carry over among the two groan types …
