Acoustic Cues Of Physical Formidability In Cage Fighters, Stefan Mattias-Maria Goetz

Wayne State University Theses

Across the animal kingdom, the sex that experiences the most reproductive variance tends to evolve sexually dimorphic traits—both behavioral and morphological—which aid in reproduction. Human evolution has been marked by greater male intrasexual selection and as a result, men display a variety of secondary sexual characteristics, putatively serving to enhance biological fitness. Among these, fundamental frequency, closely related to perception of pitch, among men is half that of women. Likewise, monotonicity, that is, variance in pitch across an utterance, is higher in men (i.e., women show greater variance in pitch) while formant dispersion, which gives the voice its timbre, is …

Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang

Wayne State University Theses

The medial temporal lobe (MTL) and prefrontal cortex (PFC) are two key brain regions that support episodic memory formation in both children and adults, but the functional developmental of these regions remains unclear. In this study, we investigated the development of neural correlates of episodic memory formation using functional MRI with a subsequent memory paradigm, administered to a cross-sectional sample of 83 children and adults. We found that MTL subregions showed an age-related increase in activation supporting memory formation of complex scenes. In addition, a functionally defined scene-sensitive region in the posterior MTL also showed similar increase and predicted better …

The Efficacy Of Online Advertising Modalities: A Prescriptive Model, Marissa Suehiro

CMC Senior Theses

With the surge of technological advancements in the 21^st century, online advertising and marketing has transformed into a multi billion-dollar industry. Nowadays, it is very likely that a company’s success is dependent on the effectiveness of its online marketing strategy. When developing an advertising plan, companies must decide what their unique advertising needs are and use appropriate advertising formats that are most effective in achieving them. Unfortunately, companies often have very little guidance about how to choose modalities for specific advertising goals. The purpose of this paper is to examine the six most widely used online advertising modalities and …

Links Among Inflammation, Sexual Activity And Ovulation Evolutionary Trade-Offs And Clinical Implications, Tierney K. Lorenz, Carol M. Worthman, Virginia J. Vitzthum

Department of Psychology: Faculty Publications

Background and objectives: We examined a mechanism that may coordinate trade-offs between reproduction and immune response in healthy women, namely, changes in inflammation across the ovarian cycle.

Methodology: We investigated C-reactive protein (CRP), an inflammation marker, across two consecutive ovarian cycles in 61 Bolivian women. Participants provided saliva samples every other day, and dried blood spots on 5–6 days spread across weeks 2–3 of each cycle. Cycles were characterized as ovulatory/ anovulatory based on profiles of reproductive hormones. Participants also reported whether they were sexually partnered with a male or sexually abstinent during the study.

Results: High early-cycle, but not …

Methylenedioxypyrovalerone (Mdpv) Mimics Cocaine In Its Physiological And Behavioral Effects But Induces Distinct Changes In Nac Glucose, Ken T. Wakabayashi, Suelynn E. Ren, Eugene A. Kiyatkin

Department of Psychology: Faculty Publications

Methylenedioxypyrovalerone (MDPV) is generally considered to be a more potent cocaine-like psychostimulant, as it shares a similar pharmacological profile with cocaine and induces similar physiological and locomotor responses. Recently, we showed that intravenous cocaine induces rapid rise in nucleus accumbens (NAc) glucose and established its relation to neural activation triggered by the peripheral drug actions. This study was conducted to find out whether MDPV, at a behaviorally equivalent dose, shares a similar pattern of NAc glucose dynamics. Using enzyme-based glucose sensors coupled with amperometery in freely moving rats, we found that MDPV tonically decreases NAc glucose levels, a response that …

Negative Urgency And Emotion Regulation Strategy Use: Associations With Displaced Aggression, Jillian Panuzio Scott, David Dilillo, Rosalita C. Maldonado, Laura E. Watkins

Department of Psychology: Faculty Publications

The numerous public health consequences of interpersonal aggression highlight the necessity of a comprehensive understanding of factors influencing its perpetration. This study examined direct and interactive associations between negative urgency and emotion regulation strategy use in predicting displaced aggression under conditions of negative mood. Participants were 197 male and female undergraduate students who were randomly assigned to employ either cognitive reappraisal or expressive suppression in response to a negative mood induction. Immediately afterward, participants engaged in an analog displaced aggression task. Results revealed direct, positive associations between negative urgency and aggression. In addition, the use of suppression was associated with …

From Sex Objects To Human Beings: Masking Sexual Body Parts And Humanization As Moderators To Women’S Objectification, Philippe Bernard, Sarah Gervais, Jill Allen, Alice Delmée, Olivier Klein

Department of Psychology: Faculty Publications

Recent studies have shown that sexualized female bodies are objectified at a cognitive level. Research using the body-inversion recognition task, a robust indicator of configural (vs. analytic processing) within cognitive psychology, shows that for sexualized female bodies, people recognize upright and inverted bodies similarly rather than recognizing upright bodies better than inverted bodies (i.e., an inversion effect). This finding suggests that sexualized female bodies, like objects, are recognized analytically (rather than configurally). Nonetheless, it remains unclear when and why sexualized female bodies are objectified at a basic cognitive level. Grounded in objectification theory, the present experiments examine moderating factors that …

Repeated Administration Of Aripiprazole Produces A Sensitization Effect In The Suppression Of Avoidance Responding And Phencyclidine-Induced Hyperlocomotion And Increases D2 Receptor-Mediated Behavioral Function, Jun Gao, Rongyin Qin, Ming Li

Department of Psychology: Faculty Publications

The present study investigated how repeated administration of aripiprazole (a novel antipsychotic drug) alters its behavioral effects in two behavioral tests of antipsychotic activity and whether this alteration is correlated with an increase in dopamine D₂ receptor function. Male adult Sprague-Dawley rats were first repeatedly tested with aripiprazole (3, 10 and 30 mg/kg, subcutaneously (sc)) or vehicle in a conditioned avoidance response (CAR) test or a phencyclidine (PCP) (3.20 mg/kg, sc)-induced hyperlocomotion test daily for five consecutive days. After 2–3 days of drug-free retraining or resting, all rats were then challenged with aripiprazole (1.5 or 3.0 mg/kg, sc). Repeated …

Examining The Reinforcement-Enhancement Effects Of Phencyclidine And Its Interactions With Nicotine On Lever-Pressing For A Visual Stimulus, Natashia Swalve, Scott T. Barrett, Rick A. Bevins, Ming Li

Department of Psychology: Faculty Publications

Nicotine is a widely-abused drug, yet its primary reinforcing effect does not seem potent as other stimulants such as cocaine. Recent research on the contributing factors toward chronic use of nicotine-containing products has implicated the role of reinforcement-enhancing effects of nicotine. The present study investigates whether phencyclidine (PCP) may also possess a reinforcement-enhancement effect and how this may interact with the reinforcement-enhancement effect of nicotine. PCP was tested for two reasons: 1) it produces discrepant results on overall reward, similar to that seen with nicotine and 2) it may elucidate how other compounds may interact with the reinforcement-enhancement of nicotine. …

Adolescent Olanzapine Sensitization Is Correlated With Hippocampal Stem Cell Proliferation In A Maternal Immune Activation Rat Model Of Schizophrenia, Shinnyi Chou, Sean Jones, Ming Li

Department of Psychology: Faculty Publications

Previous work established that repeated olanzapine (OLZ) administration in normal adolescent rats induces a sensitization effect (i.e. increased behavioral responsiveness to drug re-exposure) in the conditioned avoidance response (CAR) model. However, it is unclear whether the same phenomenon can be detected in animal models of schizophrenia. The present study explored the generalizability of OLZ sensitization from healthy animals to a preclinical neuroinflammatory model of schizophrenia in the CAR. Maternal immune activation (MIA) was induced via polyinosinic:polycytidilic acid (PolyI:C) administration into pregnant dams. Behavioral assessments of offspring first identified decreased maternal separation-induced pup ultrasonic vocalizations and increased amphetamine-induced hyperlocomotion in animals …

The Relationship Between Adhd And Trait Facets Of The Five-Factor Model, Todd William Bennett

PCOM Psychology Dissertations

Facets of the Five-Factor Model (FFM) were examined in order to understand its interaction with Attention Deficit Hyperactivity Disorder (ADHD)-symptoms. By utilizing archival data, in a correlational design, adults between the ages of 18-66 were tested for the presence of ADHD, which was then compared with data gathered from the NEO-PI-R. Comorbid psychiatric conditions often associated with ADHD were accounted for in the design. Results partially supported the hypotheses, specifically, that altruism was inversely related to Impulsivity, as predicted. However, other findings largely did not support a relationship between other specific NEO-PI-R facets and ADHD. Other significant relationships that were …

The Frequency And Competency Of Executive Functions Assessment And Intervention Among Practicing School Psychologists, Meghan A. Garrett

PCOM Psychology Dissertations

This study surveyed school psychologists (N = 167) primarily from six different states about their perceptions, knowledge, frequency, and application of executive functions assessment and interventions. The purpose of this study was to explore school psychologists’ practices in executive functions assessment and interventions. Results of the study indicated that school psychologists vary in their knowledge of executive functions, but the majority of them do not include the assessment of and intervention in executive functions deficits in their regular practice. However, school psychologists tended to report executive functions assessment and intervention more frequently when presented with specific disability classifications (e.g. autism, …

An Exploration Of Social Connectedness As A Predictor Of Quality Of Life In Acquired Brain Injury Survivors, Jennifer Oyekanmi

PCOM Psychology Dissertations

Research on quality of life in ABI survivors has focused on four domains: psychological, physical, social, and cognitive (Upadhyay, 2007). Social relationships, in particular, can help ABI survivors more effectively cope with changes in their lives, help maintain a healthy outlook, and can help with seeking further understanding of the consequences of sustaining a ABI (Hibbard et al, 2002). The current study sought to examine if social connectedness is predictive of quality of life in ABI survivors. Participants were 71 individuals who have sustained a ABI and who currently or in the past participated in a long term rehabilitation program. …

Deciphering Holland's Code, Dennis D. Turner

HIM 1990-2015

The Party Exercise found on countless career guidance websites and popularized by the best-selling, job-hunting book What Color Is Your Parachute (Bolles, 2015) purports to provide an estimate of an individual's Holland's code. This study examines whether this commonly used Party Exercise accurately predicts an individual's Holland's code (Holland, 1997). Undergraduate students (N=473) completed The Party Exercise and then the Self- Directed Search (Holland & Messer, 2013). The results of this study do not support the use of this popular “Party Exercise” as a valid estimate of an individual's Holland code.

The Effect Of Precipitation On The Spread Of Mosquito-Borne Diseases: A Case Study Of Florida Counties, Marvin Osbourne

Electronic Theses and Dissertations

The state of Florida is the third most populous state in the United States of America, with six (6) of its metropolitan areas dubbed as the fastest growing in the entire country. A mosquito bite may mean the transmission of a virus or disease which might be fatal. Hence, there is a need for the state to control mosquitoes through the various Departments of Mosquito Control in each of its sixty-seven (67) counties. Six locally acquired mosquito-borne viruses which affect humans and animals in the state of Florida were considered. This thesis used statistical methods to examine data for rainfall, …

Friendship And Informant Characteristics Associated With Agreement Among Adolescent And Friend Ratings Of Behavior Problems., Brea-Anne Lauer

Electronic Theses and Dissertations

Although teacher and parent informants often are used to gather information regarding adolescents* emotional and behavioral functioning, research has suggested that agreement among these raters and adolescents* self-ratings tends to be low to moderate. Given that friends typically play an important role in the lives of adolescents, the present study sought to determine the relative agreement amongst adolescent self-reports and those of their friends as well as factors that might impact this agreement. In particular, a sample of 207 culturally diverse high school students were matched based on perceived friendship closeness and asked to provide ratings of their own emotional …

Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster

Theses and Dissertations--Clinical and Translational Science

This dissertation introduces a framework for understanding differences in how emotional enhancement effects might influence memory in aging adults and then summarizes the findings of three studies of how repetition effects and emotional enhancement effects influence working memory in older adults without cognitive impairment (NC), older adults with amnestic mild cognitive impairment (MCI), and older adults with mild Alzheimer’s disease (AD). In these experiments, individuals with AD showed cognitive impairment in terms of accuracy and reaction time, but individuals with MCI showed milder behavioral impairment that was confined to manipulations of working memory. Individuals with AD showed relative sparing of …

Impact Of A Cognitive Behavioral Pain Management Group On Depression, Anxiety, Pain Severity, And Opioid Use In An Inpatient Population, Breanna Bocciolatt

Doctor of Psychology (PsyD)

Chronic pain has significant, multifaceted effects on both the health care system and the individual. The total cost of pain to the U.S. healthcare system is estimated to be over $600 billion annually (Skinner, Wilson, & Turk, 2012). People with chronic pain may frequent multiple providers, often dominating the time and resources of healthcare professionals (Skinner et al., 2012). The approximately 100 million people with chronic pain miss work, experience financial distress, and strained relationships, which leads to comorbid psychological diagnoses (Birnie, McGrath, & Chambers, 2012). Pain treatment strategies have largely followed a biomedical framework, seeking to identify the source …

Coping Methods That Predict Reduced Symptoms Of Posttraumatic Stress Disorder (Ptsd), Autumn Van Meter

Doctor of Psychology (PsyD)

Objective: Most individuals experience a stressful event at some point in their lives. A third to half of those individuals will meet criteria for Posttraumatic Stress Disorder (PTSD) during their lifetime. Individuals that do not develop PTSD likely have better coping skills regarding trauma. Targeting specific coping strategies that reduce PTSD symptoms helps mental health professionals and providers create interventions and prevention skills.

Method: Eighty-four participants from a university took an online survey. Demographic information were gathered. Questionnaires were given to determine if the participant had experienced one or more traumatic events. Next, a questionnaire that measured the extent that …

Depth Of A Salesman: Exploring Personality As A Predictor Of Sales Performance In A Multi-Level Marketing Sample, Colleen Rose Miller

All Graduate Theses, Dissertations, and Other Capstone Projects

Despite its growing prevalence in the realm of sales occupations, multi-level marketing (MLM) and its primary participants are not very well understood. In particular, there is a dearth of understanding in terms of the differentiating characteristics of individual sellers who are financially successful in comparison to those who perform poorly. This study sought to fill in some of these research gaps by exploring the antecedents of sales success by examining the validity of personality as a predictor of sales performance in the context of MLM. While significant relationships were indeed observed between certain facets of personality (specifically components of conscientiousness, …

Using Cognitive Word Games To Promote Lexical Memory Access And Vocabulary Retrieval In Second Language Learners, Kejkaew Thanasuan

Dissertations, Master's Theses and Master's Reports

Fluency in a second language (L2) is one of the most important skills for the modern world. However, adults learning a new language face many obstacles, including motivation, time, and other challenges in learning. Technology learning tools may help solve these problems. In this dissertation, I tested the effectiveness of cognitive word games as a vocabulary learning method, with the main goal of investigating how different word games including a crossword paradigm task, a free association task and a word-stem completion task were effective at improving vocabulary memory access. The games selectively increased semantic (meaning) or orthographic (spelling) associations in …

Development Of The Intelligent Graphs For Everyday Risky Decisions Tutor, Margo Woller-Carter

Dissertations, Master's Theses and Master's Reports

Simple graphical visual aids have now been shown to be among the most effective means of quickly improving people’s ability to evaluate and understand risks (i.e., risk literacy), particularly for diverse and vulnerable groups (e.g., older adults, less educated, less numerate, minority and immigrant samples). Although well-developed theory and standards for user-friendly graph design exist, guidelines are often violated by designers faced with constraints like conflicts of interest (e.g., persuasion and marketing vs. informed decision making). Even when information is presented in well-designed graphs, many people struggle with appropriate data interpretation. Can basic computerized graph literacy training improve essential graph …

The Role Of Salience In Second Language Acquisition, Ian South Comeaux

LSU Master's Theses

Abstract Cues to the actor role such as word order, noun animacy, case inflection and verb agreement vary in strength across languages. The competition model (CM; MacWhinney, 2005) suggests that adult L2 acquisition is difficult due to differences in cue strength between the native and target languages. Using a paradigm inspired by the CM, the present study examines whether salience plays a role in facilitating adjustments of cue strength during L2 learning. Native English speakers were exposed to an artificial language (via an actor-assignment task) which utilized four different cues: verb agreement, case marking, animacy, and word order. Word order, …

The Balloon Analogue Risk Task And Behavioral Correlates In Pigeons, Aaron P. Smith

Theses and Dissertations--Psychology

Individuals experience risk ubiquitously, but measuring risk taking is difficult. The balloon analogue risk task (BART) was developed in order to assess risk taking through having subjects press a key that accrues reward but also risk losing all reward with each press. In humans, greater responding in this task is associated with other maladaptive risk taking behaviors. The present research modeled this relationship in pigeons due to their previously shown propensity towards risk taking behavior. Experiment 1 used an unsignaled balloon task in which losing could only occur after 5 pecks. Results showed below optimal performance with greater pecks associated …

Working Memory And Symptoms Of Attention Deficit Hyperactivity Disorder In Children, Alison Margaret Colbert

Master's Theses and Doctoral Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) is a disorder mainly characterized by high levels of inattention, hyperactivity, and impulsiveness. Although ADHD is a topic of great interest in multiple domains, much remains to be explored before a thorough understanding will be possible. Recently, working memory (WM) has gained attention as a potential core deficit of ADHD. Therefore, theories of ADHD and WM may provide guidance for increased understanding of ADHD, and continued research on ADHD, guided by WM theory, will maximize the effectiveness of assessment and treatment for this disorder. The current study utilized a model integrating WM measurement and symptoms …

Personality And Creativity Correlates In Adults With Childhood Imaginary Companions, Carolyn Lasch

Scripps Senior Theses

A few studies have demonstrated differences in various personality attributes and creative abilities in children with imaginary companions. This study examined how recalled childhood engagement with an imaginary companion correlates with adult personality and creativity measures. It was hypothesized that creation of childhood imaginary companions would be positively correlated with adult creativity, but that this relationship would be mediated by certain personality attributes such as openness to experiences and extraversion. Other details of the imaginary companion experiences were also investigated. Two hundred and forty-six participants were recruited online to answer questions related to their personality and creativity, as well as …

Sleeve Gastrectomy And Roux-En-Y Gastric Bypass Alter The Gut-Brain Communication, Lindsey Ballsmider, Alexandra Vaughn, Michelle David, Andras Hajnal, Patricia Di Lorenzo, Krzysztof Czaja

Psychology Faculty Scholarship

This study investigated the anatomical integrity of vagal innervation of the gastrointestinal tract following vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) operations. The retrograde tracer fast blue (FB) was injected into the stomach to label vagal neurons originating from nodose ganglion (NG) and dorsal motor nucleus of the vagus (DMV). Microglia activation was determined by quantifying changes in the fluorescent staining of hindbrain sections against an ionizing calcium adapter binding molecule 1 (Iba1). Reorganization of vagal afferents in the hindbrain was studied by fluorescent staining against isolectin 4 (IB4). The density of Iba1-and IB4-immunoreactivity was analyzed using Nikon …

Mind-Craft: Exploring The Relation Between "Digital" Visual Experience And Orientation In Visual Contour Perception, Daniel Hipp

Graduate Dissertations and Theses

Visual perception depends fundamentally on statistical regularities in the environment to make sense of the world. One such regularity is the orientation anisotropy typical of natural scenes; most natural scenes contain slightly more horizontal and vertical information than oblique information. This property is likely a primary cause of the “oblique effect” in visual perception, in which subjects experience greater perceptual fluently with horizontally and vertically oriented content than oblique. However, recent changes in the visual environment, including the “carpentered” content in urban scenes and the framed, caricatured content in digital screen media presentations, may have altered the level of orientation …

Early Contexts Of Learning: Family And Community Socialization During Infancy And Toddlerhood, Carolyn P. Edwards, Lixin Ren, Jill Brown

Department of Child, Youth, and Family Studies: Faculty Publications

The contexts of early learning and socialization are diverse and complex but not without some predictability. The tension between predictability and variation fascinates researchers interested in childhood and culture and motivates careful exploration of different developmental niches to better understand socialization during infancy, toddlerhood, and early childhood. Contexts of early socialization vary in the people and activities present, and the beliefs and norms of caregivers and daily companions. The chapter utilizes anthropological constructs (household structure and composition, settlement patterns and subsistence level, mothers’ workload, gender division of labor, intimacy levels between husbands and wives, and cultural roles and norms pertaining …

“The Autism Adventures Of Watson & Holmes”: Puppet Theatre To Improve Elementary Students’ Knowledge Of And Attitudes Toward Autism Spectrum Disorder, Sarah N. Simon

Departmental Honors Projects

The prevalence of autism spectrum disorder (ASD) is a growing concern in schools across the nation. More students with high functioning autism are being mainstreamed, and students on and off the spectrum are being exposed to a wider variety of behaviors and new opportunities for friendship in school. Many students who fall on the autism spectrum suffer from the stigmatizing attitudes of their peers, and this stigmatization often stems from a lack of early education about mental health. Puppetry has been proven to captivate young audiences while teaching important messages in an entertaining and relatable way. The purpose of this …
