Dangerous Criminals Or Misunderstood? Assessing Police Perceptions Of The Mentally Ill, Amy Roach

Psychology Theses

People diagnosed with mental illnesses are often confronted with stigmatization and discrimination because they are stereotyped as dangerous and unpredictable. Police officers are typically the first to respond to a potentially dangerous mentally ill person and therefore, it is important to understand how police officers’ perceive mentally ill persons and how they respond to a call regarding a suspect displaying symptoms associated with mentally illness. Sixty police officers read one of six vignettes involving a call to investigate a suspicious male loitering behind a store. The vignettes differed only on the perceived severity of the mental illness (mild or severe) …

Of Mice And Mozart: Testing Spatial Reasoning And Memory Of Rats, Kaitlin O'Toole

Honors Theses

An increase in spatial-temporal reasoning has been documented in the presence of Mozart's sonata K.448; this enhancement of physical and psychological activities is called the "Mozart Effect" (Hughes 2001). This effect has been recorded in humans and animals alike, and its influence reaches a myriad of applications including calming wild animals to increasing test scores in college students to lowering high blood pressure. Using a cheeseboard apparatus to test spatial reasoning in rats, this experiment recorded the results from maze tasks completed in the presence of sonata K.448 compared to trials completed in silence. Results showed a significant difference between …

Racial Socialization In A Black-White Interracial Family In Virginia, Rebecca Hubbard

Theses and Dissertations

The Black-White biracial population is the largest and fastest growing subgroup of multiracial individuals in the United States. Despite substantial research literature on the positive relationship between Black racial identity and psychological wellbeing, Black-White biracial individuals are underrepresented in studies that provide evidence for this relationship. Root (1998) put forward an Ecological Metamodel of Biracial Identity, comprised of several factors related to contextual (e.g. class, regional history of race-relations, parental identity, extended family) and intra-psychic processes (e.g. social skills, coping skills). The ecological metamodel served as the theoretical framework for the current study. This study is a comprehensive investigation of …

Posttraumatic Stress And Myocardial Infarction Risk Perceptions In Hospitalized Acute Coronary Syndrome Patients, Donald Edmondson, Jonathan A. Shaffer, Ellen-Ge Denton, Daichi Shimbo, Lynn Clemow

Publications and Research

Posttraumatic stress disorder (PTSD) is related to acute coronary syndrome (ACS; i.e., myocardial infarction or unstable angina) recurrence and poor post-ACS adherence to medical advice. Since risk perceptions are a primary motivator of adherence behaviors, we assessed the relationship of probable PTSD to ACS risk perceptions in hospitalized ACS patients (n = 420). Participants completed a brief PTSD screen 3-7 days post-ACS, and rated their 1-year ACS recurrence risk relative to other men or women their age. Most participants exhibited optimistic bias (mean recurrence risk estimate between "average" and "below average"). Further, participants who screened positive for current PTSD (n …

Conversion Theory Through The Cognitive Science Of Religion Lense In A Christian-Muslim Context, Jennifer A. Garcia

Scripps Senior Theses

The Cognitive Science of Religion (CSR) in recent years is beginning to become more popular. This project evolves around the development of the field as well as critiques of the field. Because of the interdisciplinary nature of CSR, it lends an interesting way to understand religion as well as religious experiences. One of those religious experiences, conversion, is examined and explored through the use of conversion narratives from western women who were formally Christian but converted to Islam. Many themes arise out of this research that paves the way for trying to understand religious experiences. Overall, the project focuses on …

Expressed Emotion And Attitudes Toward Body Image And Food, Toni Marie Maraldo

Undergraduate Honors Thesis Collection

In numerous studies over the years, body image and dysfunctional attitudes toward food have shown to be related to the genesis of eating disorders. Recent research has particularly focused on the influence that families have on both the development of eating disorders as well as their impact on their child's body image and eating attitudes. In general, higher levels of expressed emotion are often found in families with children who have either anorexia nervosa or bulimia nervosa. However, there is a lack of research on sub-clinical populations. Therefore, the purpose of this study is to analyze the influence that expressed …

Sleep Deprivation And Delusion Proneness: Influence On Dream Bizarreness, Anna Leigh Lezon

Undergraduate Honors Thesis Collection

While evidence for many types of psychotic experience exists in the general population, dreams have been a particularly prominent model for hallucinations and delusions in otherwise healthy individuals. This definition of "bizarreness" in dreams mirrors the description of psychosis in schizophrenia patients when their psychosis remits (Colace, 2003). Babkoff et al, (1989) found a linear association - less sleep caused more waking-state hallucinations. While the relationship between psychotic symptoms and sleep deprivation is well established, most existing data regard waking-state psychotic symptomology. The relationship between sleep deprivation and dream-state psychotic symptomology has not been investigated. Further, no sleep deprivation study …

Various Gaits Of African Elephant Calves, Elizabeth Anne Jennings

Undergraduate Honors Thesis Collection

It is commonly believed that elephants exhibit only one gait, a lateral sequence walk. However, recently there have been several interesting studies on the footfall patterns of adult African elephants (Loxodonta africana). Scientists have recognized that elephants actually exhibit two patterns of locomotion: a lateral sequence walk and an amble. The amble is a slight modification of the lateral sequence gait. The present study extends this work by examining the relationship between gait and speed in African elephant calves at the Indianapolis Zoo. I collected frame-by-frame observational video data from a newborn calf born at the Indianapolis Zoo across a …

Personality Traits And Desire For Social Distance From Individuals With Mental Illnesses, Emily Lazar

Undergraduate Honors Thesis Collection

The current study sought to examine the relationship between personality traits and desire for social distance from an individual perceived as having a mental illness. Each participant received information about a confederate's (person pretending to be a participant) past mental illness diagnoses before interacting with them. This information was presented in the form of a demographic questionnaire completed by the confederate and, among other details, mentioned that the confederate had been previously diagnosed with schizophrenia. Participants' desire for social distance from the confederate was measured both by videotaped behavioral reactions and by attitudinal reactions reported on a social distance questionnaire …

Measures Of Social Cognition In The Laboratory And Real World: Towards Temporal Dynamics Of Implicit Other-Regard, Danielle Tucci

Scripps Senior Theses

Social cognition is a fundamental aspect of human experience that enables us to have relationships with and understanding of other people. Social relationships have been shown to mitigate cognitive decline in old age and benefit cognitive functioning, and the social interaction on which these relationships rely requires an extensive network of cognitive processes, and by extension neural systems, that have not, as of yet, been widely studied in older adults. Nor has the function of these systems been tied to social relationships in the real world. Here, I will compare self-reports of real-world quality and extent of social networks with …

If You're Happy And You Know It: Concentrate!, Kristi Michelle Summers

Undergraduate Honors Thesis Collection

The phenomenon of mind wandering involves a situation in which a person's executive control switches from the current task to unrelated thoughts (Smallwood & Schooler, 2006). Previous research has indicated that individuals mind wander more often when they are in negative moods than when they are happier (Killingsworth & Gilbert, 2010; Smallwood, 2009). One theory of mind wandering, the Working Memory Capacity Theory, claims that participants with a lower working memory capacity (WMC) experience more mind wandering during a challenging primary task than participants with a higher WMC because those with higher WMC can better use their executive control to …

The Story Of Taste: Using Eegs And Self-Reports To Understand Consumer Choice, Charnetta Brown, Adriane B. Randolph, Janée N. Burkhalter

The Kennesaw Journal of Undergraduate Research

The authors investigate consumers’ willingness to switch from a preferred manufacturer brand to an unfamiliar private-label brand if taste is perceived as identical. Consumer decisions are examined through recordings of electrical brain activity in the form of electroencephalograms (EEGs) and self-reported data captured in surveys. Results reveal a willingness of consumers to switch to a less-expensive brand when the quality is perceived to be the same as the more expensive counterpart. Cost saving options for consumers and advertising considerations for managers are discussed.

Career Calling And Work Motivation In Traditional And Non-Traditional College Students, Cara Wells

Honors Theses

The purpose of this study was to help define career-related calling through the perception of traditional (18 to 24 years of age) and non-traditional (25 and older) college students and identify what variables of motivation are related to calling. Three hundred and fifty-one participants completed an online survey that measured calling through The Career and Vocational Questionnaire (CVQ), and motivation through the Work Preference Inventory (WPI). Pearson Correlation and independent t-test were used in statistical analysis. Correlational analysis revealed that presence of calling and search for calling are significantly related to intrinsic motivation. Analysis also showed that level of presence …

Life Without Parole: The Influence Of Age And Race On The Sentencing Of Juvenile Offenders, Maria Annabel Mireles

Psychology Theses

In 2010, the Supreme Court ruled it unconstitutional to sentence adolescents charged with non-homicide crimes to life without parole (Graham v. Florida, 2012). Currently, research regarding life without parole is assessed in conjunction with the death penalty, in which life without parole is proposed as a lesser alternative to the death penalty. The current study investigated whether age and race are predictive factors in sentencing juvenile offenders. A sample consisting of 225 undergraduate students were presented with one of six case scenarios adapted from Wilkins v. Missouri (1985) in which the defendant’s age (13, 15, 17) and race …

Identification Of Latent Subgroups Of Obese Adolescents Enrolled In A Healthy Weight Management Program, Cassie Brode

Theses and Dissertations

In obesity research, it is assumed that the population is homogeneous. While this approach has yielded important insights, testing this supposition might reveal information that could impact our understanding of the phenomena and its treatment. In this study, data from obese teenagers (N = 248, Mean BMI percentile = 99%; Mean age = 13.9, SD = 1.8) who were predominantly minority (n = 182), female (n = 169), and enrolled in a weight loss intervention were analyzed. Latent profile analysis (LPA) was used to segment patients into groups based on their scores on PedsQL 4.0 scales (physical-, emotional-, social-, and …

Efficacy Of Reach Forgiveness For Foreign And Virginia Students, Yin Lin

Theses and Dissertations

People agree that forgiveness is a virtue in essentially all countries. However, different cultures have different ideas about how willing one should forgive and under what circumstances. Although the study occurred in the USA, I recruited both foreign-extraction and Virginia born-and-raised female college students (N=102) to participate a six-hour REACH forgiveness intervention, promoting their forgiveness through psychoeducational groups. In my thesis, I investigated whether students of foreign extraction and Virginia-born students would respond similarly to the intervention. I operationalized culture in two ways—by country and by individual self-reported self-construal. I measured forgiveness using two measures—decisional forgiveness and emotional forgiveness. I …

Young Black Children's Representations Of The Father Figure In Low-Income Households, Shawnae Shalae Thompson

Honors Scholar Theses

This study investigated the cognitive-emotional schemas surrounding the father role in 50 young, low-income, Black children in relation to the amount of father involvement in the first 5 years of their lives. These representations were framed within four parenting categories: Nice, Mean, Authoritative, and Authoritarian. Diana Baumrind’s parenting style framework was utilized to create the Authoritative and Authoritarian parenting categories. This question was investigated in low-income families; the impact of gender of the child was also considered. Information on fathers’ involvements in the children’s lives were gathered through interviews and self-reports from the children’s fathers and mothers. Story Stem Narrative …

Ketamine Can Disrupt Episodic Memory (Hours To Days) Consolidation: Effects Of Varying Dose And Retention Intervals, Ryan Darius Tabtabai

Honors Scholar Theses

Memory consolidation is the process wherein short-term, episodic memories are converted into stable, long-term representations. Forebrain N-methy-d-aspartate receptors (NMDARs), particularly frontal cortical and hippocampal receptors, are thought to play a key role in neuronal plasticity and memory consolidation. Ketamine is an NMDA antagonist that disrupts memory, particularly encoding and retrieval processes. Previously we have observed no effect of post-acquisition ketamine treatment (50-100 mg/kg) on memory consolidation in rats performing a delayed-match-to place radial water maze task. The current study reexamined the effects of ketamine (25-100 mg/kg) on memory consolidation in this task over varying retention intervals (4, 24, and 48 …

Young Adult Cancer Survivors' Satisfaction With Interpersonal Life Changes, Kelly J. Foy

Honors Scholar Theses

This study looked at the life satisfaction of young adult cancer survivors in comparison to adult cancer survivors. Satisfaction was focused on three separate domains: romantic relationships, fertility and sexuality, and family and friendships. 292 participants completed the survey, which included measures such as the Zebrack Cancer Impact Scale, the Ferrans and Powers Quality of Life Index, the Post-Traumatic Growth Scale, and a new measure developed for this study. Bivariate correlation analyses were used to identify significant relationships among the domains. It was determined that there was no significant difference between young adult cancer survivors and adult cancer survivors in …

Honors Retention: The Persistence Of Juniors And Seniors In The Honors Program Through Examination Of Commitment To Completion Of Honors Thesis, Amy A. Holland

Honors Scholar Theses

The goal of the Honors Program is to engage intellectually stimulated students in a unique, challenging experience culminating in the writing of an undergraduate thesis, a piece of scholarly work. The four elements to the mission of the Honors Program include challenging academics, a scholarly environment, a supportive community, and on-campus engagement. This study conducted a qualitative assessment of the Honors Program through written questionnaires and oral interviews of ten juniors or seniors either completing an Honors Thesis or not committed to the Thesis. This research did not find significant differences between these two groups due in part to small …

Adenosine-Dopamine Interactions In The Open Field Arena: Studies Related To Locomotion And Anxiety, Rothem Kovner

Honors Scholar Theses

Nucleus accumbens dopamine (DA) is an important regulator of locomotion. The neuromodulator adenosine also has a role in regulating locomotion. The adenosine A_2A receptor subtype is colocalized with DA D2 receptors on medium spiny neurons in the striatum and nucleus accumbens. Interactions between adenosine A_2A and DA D2 receptor antagonists are significant for regulating various aspects of motor and motivational function. The adenosine A_2A antagonist MSX-3 has been shown to reverse the suppression of locomotion induced by the DA D2 antagonist eticlopride. The structure of MSX-3 was modified to produce the prodrug MSX-4 which has high oral …

Effort-Related Choice Behavior Is Affected By Pharmacological Manipulations Associated With Depression: The Effects Of Tetrabenazine, Megan Huizenga

Honors Scholar Theses

In humans, psychiatric symptoms such as anergia and psychomotor retardation reflect pathologies in behavioral activation. These motivational symptoms are fundamental aspects of depression and other disorders. Drugs such as reserpine and tetrabenazine deplete monoamines, including dopamine, and induce depressive like behaviors in humans. Our results indicate that administration of low doses of tetrabenazine can alter effort-related choice behavior, biasing animals towards low effort alternatives. These findings may be related to the ability of monoamine depleting agents such as tetrabenazine to blunt behavioral activation and induce psychomotor retardation, anergia and fatigue in humans, and this research could be useful for the …

Intragroup Attitudes Of The Lgbt Community: Assessment And Correlates., David W. Hutsell

Undergraduate Honors Theses

The intragroup attitudes of the lesbian, gay, bisexual, and transgender community are examined. A general overview of heterosexuals’ views about LGBT persons is considered before reviewing past research on intragroup attitudes that may exist within the LGBT community. Since little work has been done in this area, to fill gaps in the literature a study of 533 self-identified LGBT individuals was conducted to assess attitudes towards each specific subgroup (lesbian, gay male, bisexual male, bisexual female, male-to-female transgender, and female-to-male transgender) of the LGBT community. Several variables, including group identification, perceived stigma, outness, and contact, were examined as predictors intragroup …

Family Context And Weight Status Among 18-Month-Old Infants In Southern Appalachia: The Role Of Temperament, Parenting Style, And Maternal Feeding Practices., Vincent A. Carroll

Undergraduate Honors Theses

Pediatric obesity is a major public health crisis in the United States, and is particularly prevalent in the Southeast. Recent research has shifted the focus toward identifying obesity risk factors earlier in the lifespan, as 9.7% of infants and toddlers are at high weight-for-length (>95th percentile). Family context variables have been found to be related to infant and child weight status. A better understanding of these early contributors may facilitate the continued development of interventions for infants and toddlers at risk for obesity.

The purpose of the current study was to examine infant weight as it relates to parent-report …

Weight Concerns, Body Image, And Smoking Cessation In Pregnant Women In Rural Appalachia, Jennifer Aileen Correll

Electronic Theses and Dissertations

Smoking is the leading preventable cause of death, and smoking during pregnancy can lead to significant health complications for both the mother and developing child. In the Appalachian region of East Tennessee, pregnancy smoking rates are as high as 40% in some counties which is almost 4 times the national average. Weight and body image concerns have previously been identified as variables contributing to maintenance of smoking behavior. The current study was designed to examine the relationship between prepregnancy weight and body image concerns and smoking status at third trimester. Participants included 172 pregnant women who smoke. Women were recruited …

The Development Of The Well-Being Interview, Craig Alexander Asselin

Dissertations, 2014-2019

Although psychologists and psychotherapists have long been concerned with the construct of well-being, currently there exist only self-report measures of the construct. This is potentially problematic because, as a number of researchers have pointed out, there are many different kinds of biases that can undermine the validity of data obtained from self-report measures. The purpose of this project was to develop a comprehensive, user-friendly, clinician administered interview to assess well-being. In order to accomplish this, the Well-Being Interview (WBI) was developed, based on recent developments in positive psychology (e.g., Diener (2000), Ryff (1995) and Seligman (2011) and theoretical unification (Henriques, …

Mothers Do Not Drive The Development Of Adult Homesign Systems: Evidence From Comprehension, Emily Carrigan

Master's Theses

Studying the communication systems that arise in spontaneously occurring cases of degraded linguistic input can help clarify human predispositions for language. Some deaf individuals born into hearing families, who do not receive conventional linguistic input, develop gestures, called “homesign,” to communicate. We examined homesign systems used by four deaf Nicaraguan adults (ages 15-27), and evaluated whether homesigners’ hearing mothers are potential sources for these systems. Study One measured mothers’ comprehension of descriptions of events (e.g., “A man taps a woman”) produced in homesign and spoken Spanish. Mothers comprehended spoken Spanish descriptions (produced by one of their hearing children) better than …

Intercollegiate Cross-Country Competition: Racing Is Associated With A Substantial Increase In Salivary Levels Of Cortisol And Testosterone In Men And Women, Kathleen Virginia Casto

Masters Theses, 2010-2019

Athletic competition, containing both psychological and physical components, has been shown to be associated with levels of testosterone (T) and cortisol (C) in anticipation of, and during, competition. In the current research, 16 male and 22 female members of a collegiate cross country team gave saliva samples before warm-up, after warm-up, and immediately after the finish of an intercollegiate cross-country meet. Finish times were recorded as a measure of performance outcome. Participants also completed the Mental Toughness in Sport Questionnaire (MTSQ). For both men and women, after-race levels of salivary C and T were substantially elevated relative to before and …

Assessing The Utility Of A Brief Abstinence Test For Initiating Caffeine Abstinence, Bradley T. Joachim

Masters Theses, 2010-2019

Caffeine is the most commonly consumed drug in the world. Although its effects are relatively mild when consumed in moderate amounts, there exist cases where caffeine use is problematic. Currently no behavioral intervention for problematic caffeine consumption exists in which caffeine use is verified beyond self-reports. No measures of caffeine dependence and withdrawal exist either. The current study examined the viability of contingency management, an empirically supported behavioral intervention for reducing drug use, for initiating abstinence from caffeine consumption among college students of varying levels of use, as well as validity evidence for novel measures of caffeine dependence and withdrawal. …

Interaction Between Source And Filter In Vowel Identification, Christopher James Becker

Masters Theses, 2010-2019

Speech sounds can be modeled as a product of two components: the source and the filter. The effects of filter manipulations on speech perception have been studied extensively, while the effects of source manipulations have been largely overlooked. This study was an attempt to assess the impact of source manipulations on vowel identification. To this end, two source manipulations were conducted prior to filtering. First, several harmonics of the source sawtooth wave that were located near formant peaks were mistuned, either towards or away from the peaks. Mistuning towards formant peaks was expected to facilitate vowel identification by helping to …
