Disgust Sensitivity, Sexual Trauma History, And Female Sexual Functioning, Tara Mcgahan May 2012

Disgust Sensitivity, Sexual Trauma History, And Female Sexual Functioning, Tara Mcgahan

Graduate Theses and Dissertations

Sexual dysfunctions are a common problem for women that negatively impact quality of life (Laumann, Paik, & Rosen 1999). A history of sexual trauma is associated with an increase in sexual difficulties (Neumann et al., 1996). One common reaction to unwanted sexual contact is disgust (Whealin & Barnett, 2010). However, the role of disgust in the relationship between sexual trauma and female sexual dysfunction has not been examined. This study explored how disgust and a history of sexual trauma related to different domains of sexual functioning (desire, arousal, lubrication, orgasm, satisfaction, and pain). Furthermore, this study assessed whether disgust mediated …


Personality Assessment In African Elephants (Loxodonta Africana), Kristina Marie Horback May 2012

Personality Assessment In African Elephants (Loxodonta Africana), Kristina Marie Horback

Dissertations

The following study assessed personality in twelve African elephants using both observational behavior coding and standardized trait rating methods, thus demonstrating consistent individual differences across time and contexts. During the summer of 2010 and 2011, over 640 hours of behavioral data were collected onsite at the San Diego Zoo Safari Park in Escondido, CA. Four coding-based personality traits were determined after analysis: PLAYFUL, CURIOUS, TOLERANT, and, AGGRESSIVE. This data was then compared to survey ratings completed by the animal keeper staff during both summers. Four rating-based personality traits resulted from this analysis: PLAYFUL, CURIOUS, TIMID, and, AGGRESSIVE. All eight composite …


Associations Between Binge Eating And Executive Functioning Among Young Women, Nichole Kelly Apr 2012

Associations Between Binge Eating And Executive Functioning Among Young Women, Nichole Kelly

Theses and Dissertations

Binge eating is a pervasive disordered eating behavior associated with numerous psychological and physical comorbidities. Preliminary research indicates that emotion regulation difficulties, behavioral impulsivity, and executive dysfunction may contribute to the onset and/or maintenance of these behaviors. However, few studies have utilized neuropsychological measures to examine this link, and the assessment of behavioral and cognitive emotion regulation strategies are limited in scope. The purpose of the current study was to gain a deeper understanding of the emotional, behavioral and cognitive processes associated with binge eating behavior. Greater clarity regarding how these factors relate to binge eating is critical to the …


Dissociating Allopregnanolone Mnemonic Effects From Sedation, Sarah B. Hartman Apr 2012

Dissociating Allopregnanolone Mnemonic Effects From Sedation, Sarah B. Hartman

Honors Projects

Allopregnanolone (Allop) is a neurosteroid metabolite of progesterone. Allop modulates cognition, specifically learning and memory, but these effects are frequently confounded by its anxiolytic and sedative properties. We attempted to dissociate the anxiolytic effects of Allop from its mnemonic effects by employing a pharmacological challenge with d- amphetamine. Because previous research suggests that the effects of Allop may vary with the cognitive domain being tested, we assessed both spatial and non-spatial memory. Spatial memory was tested in a Morris Water Maze, and non-spatial object memory was tested on a novel discrimination task. Allop, alone or in combination with d-amphetamine …


Using A Reinforcer Hierarchy To Increase Compliance And Skill Acquisition, Bertilde U. Kamana Apr 2012

Using A Reinforcer Hierarchy To Increase Compliance And Skill Acquisition, Bertilde U. Kamana

Honors Theses

The purpose of this intervention is to increase compliant behavior and skill acquisition in a child who has been diagnosed with Autism Spectrum Disorder (ASD) with the use of a reinforcer hierarchy. This hierarchy will be determined by conducting preference assessments. These assessments are established by allowing the child to choose the most preferred object of at least two objects which are presented to him by his tutor—a preference assessment can also be conducted by observing which objects or toys the child chooses to interact with the most in his environment. When the preference assessment is established, a reinforcer matrix …


Adolescent Decision Making And Risk Behavior: A Neurobiological Approach, Jennifer M. Wolff Apr 2012

Adolescent Decision Making And Risk Behavior: A Neurobiological Approach, Jennifer M. Wolff

Department of Psychology: Dissertations, Theses, and Student Research

In this study, the neurobiological theory of adolescent decision making and risk taking and the dual-process decision making theory were tested in a sample of college students. Participants responded to questions in a survey about decision making style, socio-emotional processes, cognitive control processes, and deviant peers. The goals of the research were to test the relation between decision making processes (intuitive and deliberative) and risk behaviors, to test the potential overlap between intuitive and deliberative decision making as described in the more traditional dual-process models and the socio-emotional and cognitive control systems of the neurobiological model, and to extend the …


Poppies And Ptsd: Opioid Influence On A Preclincal Model Of Posttraumatic Stress Disorder., Sarah Vunck Apr 2012

Poppies And Ptsd: Opioid Influence On A Preclincal Model Of Posttraumatic Stress Disorder., Sarah Vunck

Theses and Dissertations

Posttraumatic Stress Disorder (PTSD) is an anxiety disorder that affects over 7.7 million adults and carries an estimated societal cost of $3.1 billion every year. People develop PTSD after exposure to a traumatic event. Alone or combined, approved pharmacotherapies or psychotherapy are somewhat effective, but symptoms for many remain refractory. Emerging evidence suggests that opiate systems may modulate the development and expression of PTSD, and their role can be investigated preclinically. Pavlovian fear conditioning is a preclinical model which elicits behaviors mirroring those that occur in humans during and after exposure to trauma. This presents an experimental tool that can …

An Exploration Of Communication And Bullying Behavior, Danielle M. Ensch Apr 2012

An Exploration Of Communication And Bullying Behavior, Danielle M. Ensch

Master's Theses and Doctoral Dissertations

This communication study examined in-depth interviews, the situational perceptions and self-awareness of individuals who bullied in middle school and/or high school. Research statement one is what motivates an individual to engage in bullying behavior and/or become a bully. Research statement two is the bully’s situational perceptions of bullying. Quantitative and qualitative research was implemented to set up the context and situation for underlying themes from the in-depth interviews. Results showed that children do not take responsibility for their bullying and will not stop unless forced to. Furthermore, the adults perceived parents and school officials to have an important role in …


What Propels Sexual Homicide Offenders? Testing An Integrated Theory Of Social Learning And Routine Activities Theories, Heng Choon Chan Apr 2012

What Propels Sexual Homicide Offenders? Testing An Integrated Theory Of Social Learning And Routine Activities Theories, Heng Choon Chan

USF Tampa Graduate Theses and Dissertations

Sexual homicide is a rare occurrence. Little is known about the offending perspective of sexual homicide from a criminological standpoint. Recently, Chan, Heide, and Beauregard (2011) proposed an integrative theoretical framework using concepts and propositions of Social Learning Theory (differential association, definitions, differential reinforcement or punishment, and imitation) and Routine Activities Theory (a motivated offender, an attractive and suitable target, and the absence of a capable guardian or guardianship) to elucidate the sexual homicide offending dynamics. According to this integrative model, the individual-level view of the sexual murderers is explained by …


Predator-Based Fear Conditioning: A Novel Approach To The Study Of The Neurobiology Of Memory, Joshua D. Halonen Apr 2012

Predator-Based Fear Conditioning: A Novel Approach To The Study Of The Neurobiology Of Memory, Joshua D. Halonen

USF Tampa Graduate Theses and Dissertations

This series of experiments developed novel paradigms involving the integration of conventional and ethologically relevant forms of reinforcement in the study of fear conditioning in rats. Experiment 1 compared the effects of foot shock, immobilization and predator exposure, alone and in combination, on the expression of conditioned fear memory and extinction. The combination of all 3 reinforcers produced a significantly stronger fear memory and greater resistance to extinction, compared to when each reinforcer was administered alone. Furthermore, whereas conditioning with foot shock, alone, resulted in rapid extinction of the fear memory, the combination of immobilization and cat exposure, or all …


From Immortal To Mortal: Objectification And Perceptions Of A Woman's Soul, Nathan A. Heflick Apr 2012

From Immortal To Mortal: Objectification And Perceptions Of A Woman's Soul, Nathan A. Heflick

USF Tampa Graduate Theses and Dissertations

Abstract

Objectification most literally refers to perceiving a person as an object. Research shows that when people focus on a woman's appearance, compared to her personality, she is perceived of as more of an object (e.g., lower in human nature traits). These objectification effects, however, rarely occur for male targets. Moreover, humans, unlike objects, are typically believed to have a soul, that is, some part of the self that outlasts the death of the physical body and extends into a post-mortem existence (e.g., Heaven). In turn, I hypothesized that women, but not men, would be perceived as having less soul …


Social Effects On Vocal Ontogeny In An Ungulate, The Goat, Capra Hircus, Elodie F. Briefer, Alan G. Mcelligott Apr 2012

Social Effects On Vocal Ontogeny In An Ungulate, The Goat, Capra Hircus, Elodie F. Briefer, Alan G. Mcelligott

Sentience Collection

Vocal plasticity is the ability of an individual to modify its vocalizations according to its environment. Humans benefit from an extreme form of vocal plasticity, allowing us to produce a wide range of sounds. This capacity to modify sounds has been shown in three bird orders and in a few nonhuman mammal species, all characterized by complex vocal communication systems. In other mammals, there is no evidence for a social impact on vocal development. We investigated whether contact calls were affected by social environment and kinship during early ontogeny in goats, a highly vocal and social species. To test the …


The Cognitive Representation Of Fantasy Versus Pretense, Colleen Mcinnis Apr 2012

The Cognitive Representation Of Fantasy Versus Pretense, Colleen Mcinnis

Psychology Student Scholarship

Do our minds process fantasy, pretense, and reality differently? Participants read fantastical (Snow White eating an apple), pretend (a girl pretending to be Snow White), or realistic (a girl eating an apple) vignettes. Participants’ reaction to a property of each vignette’s realistic context (apple as ‘delicious’) or its unrealistic context (apple as ‘poisonous’) was measured by a computer program. Differences in study 1 reaction time indicate that fantasy may require different mental representation than pretense and reality. Differences in study 2 fail to duplicate results from the fantasy condition in study 1, instead finding differences in mental representation after reading …


Examining The Effects Of Fear Of Failure, Self-Efficacy And Gender Role Conflict In Male And Female Engineering Students, Krista L. Nelson Apr 2012

Examining The Effects Of Fear Of Failure, Self-Efficacy And Gender Role Conflict In Male And Female Engineering Students, Krista L. Nelson

Doctoral Dissertations

The field of engineering continues to have significantly fewer women engineers than men. Engineering has long been considered to be a male dominated career, with fewer women receiving bachelor's degrees in engineering and gaining employment in the engineering field. The present study was an attempt to determine influencing factors that discourage women from pursuing engineering as an educational and career choice. The current study examined gender role conflict, self-efficacy, and fear of failure as potential factors influencing women's preferences to pursue an engineering degree. Both male and female genders were participants in the research to determine gender differences for these …


Research Motivation In Professional Psychology Doctoral Students: Examination Of The Psychometric Properties Of The Research Motivation Scale, Carly Bischoff Mayer Apr 2012

Research Motivation In Professional Psychology Doctoral Students: Examination Of The Psychometric Properties Of The Research Motivation Scale, Carly Bischoff Mayer

Doctoral Dissertations

Previous research suggests that the majority of clinical and counseling psychology doctoral students report low levels of research interest while in graduate school, and indicate little or no intention to pursue postdoctoral research despite having been trained within a scientist-practitioner model. Contextual and individual factors related to research interest, such as the research training environment (RTE) and self-efficacy, have been identified as potential contributors to research outcomes. Although these variables seem to be linked, many studies have found that they do not account for a substantial portion of variation in research interest. Recently, Deemer, Martens, and Buboltz (2010) developed the …


The Effect Of Different Training Regimens On Improved Sound Frequency Discrimination In Wistar Rats, Sam Cain, Elizabeth Grigoletti, Erin Walsh Apr 2012

The Effect Of Different Training Regimens On Improved Sound Frequency Discrimination In Wistar Rats, Sam Cain, Elizabeth Grigoletti, Erin Walsh

Symposium on Research and Creative Expression (SORCE)

Rat subjects were randomly assigned to one of three groups. The rats were presented with differing patterns of target and non-target frequencies, with the target remaining constant between groups while the non-target varied between groups. The rats were rewarded with food for successful bar presses while the target tone was playing, and no reinforcement was delivered for presses that occurred during the non-target tone. The groups were labeled as Control, Rapid, and Gradual. The control group experienced a silence in the place of non-target tone, while the rapid and gradual groups received the same tone in the beginning, but the …


Language And Memory For Motion Events: Origins Of The Asymmetry Between Source And Goal Paths, Laura Lakusta, Barbara Landau Apr 2012

Language And Memory For Motion Events: Origins Of The Asymmetry Between Source And Goal Paths, Laura Lakusta, Barbara Landau

Department of Psychology Faculty Scholarship and Creative Works

When people describe motion events, their path expressions are biased toward inclusion of goal paths (e.g., into the house) and omission of source paths (e.g., out of the house). In this paper, we explored whether this asymmetry has its origins in people's non-linguistic representations of events. In three experiments, 4-year-old children and adults described or remembered manner of motion events that represented animate/intentional and physical events. The results suggest that the linguistic asymmetry between goals and sources is not fully rooted in non-linguistic event representations: linguistic descriptions showed the goal bias for both kinds of events, whereas non-linguistic memory for …


Human-Canine Relationships: Dog Behavior And Owner Perceptions, Briannan K. Byrd Apr 2012

Human-Canine Relationships: Dog Behavior And Owner Perceptions, Briannan K. Byrd

Senior Honors Theses

Abstract

Owning a dog has many physiological and psychological advantages; however, dog behavior can manifest itself in a variety of negative ways, including aggression. Research suggested that genetics and environment might play a role in aggression. It was demonstrated that owners can affect their dogs’ behaviors. Owners can unwittingly condition or encourage their dogs to misbehave, whether through their inaccurate perceptions or misguided actions towards the dogs. Dog behavior specialists view owner education as the key to solving the communication barrier between human and canine. The present study’s purpose was to assess if this view was possible. The research question …


Quality And Quantity Of Sleep Study And Its Relationship To The Performance Of Lpga Tour Players, Maria Elena Lopez Apr 2012

Quality And Quantity Of Sleep Study And Its Relationship To The Performance Of Lpga Tour Players, Maria Elena Lopez

Doctoral Dissertations and Master's Theses

The relationship between sleep efficiency and elite level athletic performance that has a definitive and individual measure of performance (like golf, track, & swimming) has never been systematically studied. The extreme and rigorous travel schedules of professional golfers prevent consistent and necessary sleep schedules. The Ladies Professional Golf Association (LPGA) permitted Embry-Riddle Aeronautical University (ERAU) to ask for volunteers at two tournaments during October of 2010 to complete subjective sleep fatigue logs. Analysis of the sleep fatigue logs revealed a relationship between sleep quality and performance (golf score). Subsequent relationships were also found between subjective fatigue and sleep quality, and …


The Effects Of Different Optokinetic Drum Rotation Speeds On Motion Sickness Symptoms, Cognitive Performance And Sleep Amount, Wilfredo Rodríguez-Jiménez Apr 2012

The Effects Of Different Optokinetic Drum Rotation Speeds On Motion Sickness Symptoms, Cognitive Performance And Sleep Amount, Wilfredo Rodríguez-Jiménez

Doctoral Dissertations and Master's Theses

Symptoms of motion sickness can be disruptive to human performance. If vection-induced motion sickness symptoms, sleep amount disruptions, and worsening of cognitive performance can be measured and characterized, there are practical implications for equipment design, especially for virtual reality devices and simulators. The researcher conducted three studies. The first study examined the effects of different rotation speeds (0 RPM, 5 RPM, and 10 RPM) of the optokinetic drum on motion sickness symptoms. Motion sickness symptoms were measured using the Simulator Sickness Questionnaire (SSQ). Before exposure to the optokinetic drum, participants were not significantly different from one another in terms of …


On Discriminating Between Geometric Strategies Of Surface-Based Orientation, Bradley R. Sturz, Kent D. Bodily Apr 2012

On Discriminating Between Geometric Strategies Of Surface-Based Orientation, Bradley R. Sturz, Kent D. Bodily

Psychology: Faculty Publications

Recently, a debate has manifested in the spatial learning literature regarding the shape parameters by which mobile organisms orient with respect to the environment. On one hand are principal-axis-based strategies which suggest that organisms extract the major and minor principal axes of space which pass through the centroid and approximate length and width of the entire space, respectively. On the other hand are medial-axis-based strategies which suggest that organisms extract a trunk-and-branch system similar to the skeleton of a shape. With competing explanations comes the necessity to devise experiments capable of producing divergent predictions. Here, we suggest that a recent …


The Association Of Cognitive Function With Autonomic-Cardiovascular Reactivity To And Recovery From Stress, Sanjay Mehta Apr 2012

The Association Of Cognitive Function With Autonomic-Cardiovascular Reactivity To And Recovery From Stress, Sanjay Mehta

Psychology Theses & Dissertations

The contribution of stress in the development of chronic and terminal disease has garnered significant interest in contemporary research. The current study aims to look at how performance in domains of cognitive function may affect autonomic-cardiovascular reactivity and recovery to psychologically stressful tasks as such reactions, over time, may contribute to the development of cardiovascular disease.

The current study analyzed data from 209 healthy middle-age adults. This included four neuropsychological tests utilized here to represent abilities in four different cognitive domains: response inhibition, mental flexibility, verbal memory, and nonverbal memory. The participants were also introduced to three psychologically stressful tasks …


An Investigation Into The Relationship Between An Engineering Manager's Purpose-Seeking Beliefs And Behaviors And The Engineering Manager's Perception Of Employee Creativity, Initiative And Purpose-Seeking Behavior, Charles Burton Daniels Apr 2012

An Investigation Into The Relationship Between An Engineering Manager's Purpose-Seeking Beliefs And Behaviors And The Engineering Manager's Perception Of Employee Creativity, Initiative And Purpose-Seeking Behavior, Charles Burton Daniels

Engineering Management & Systems Engineering Theses & Dissertations

Organizations have placed an overwhelming emphasis on extrinsic motivation of its workforce, normally in the form of financial incentives, in an attempt to assure individual and organizational high performance. While a significant level of financial resources is expended in this attempt to predict and influence employee behavior, no objective evidence exists of a favorable return of investment. In fact, the primary impact of most extrinsic motivation might actually be demotivation – the opposite of the intended use.

In this research the prevailing literature was examined and a conclusion about the power of both extrinsic and intrinsic motivation was synthesized to …


Implicit Encoding Explored Through The Flankers Task, Jaclynn V. Sullivan Apr 2012

Implicit Encoding Explored Through The Flankers Task, Jaclynn V. Sullivan

Honors Projects

The problem we examined involves the process of selective attention and its relationship with implicit and explicit memory encoding. One task that has been used previously to examine selective attention is the flankers task, which consists of three items with the center item being the item that requires a response - the target. The two items on either side of the target are the “irrelevant” flankers. The correlated flanker effect is the difference in reaction time between the trials in which the flankers that are correlated with the correct response are present (congruent) and trials in which the flankers correlated …


Evaluating The Effectiveness Of Standardized And Personally Relevant Stimuli In Two Mood Induction Procedures, Kathleen Hazlett Apr 2012

Evaluating The Effectiveness Of Standardized And Personally Relevant Stimuli In Two Mood Induction Procedures, Kathleen Hazlett

Master's Theses (2009 -)

The experience of emotion is a critical component of behavior, cognition, and general human functioning. In order to better understand emotional experience, researchers have utilized mood induction procedures (MIPs) to elicit specific emotional responses. Previous studies have reviewed the effectiveness of various MIPs; however, these studies do not account for more recently developed picture datasets and are limited in their examination of the impact that personal relevance has on MIP effectiveness. The present study examined changes in emotion using four different MIPs that varied based on stimuli type (either Picture or Vignette) and relevance to the participant (Personally Relevant or …


The Effect Of Mainstream Media On Body Image And Stress Reactivity In Latina Females, Madison L. Noble Mar 2012

The Effect Of Mainstream Media On Body Image And Stress Reactivity In Latina Females, Madison L. Noble

Pitzer Senior Theses

The role of mainstream media in women’s views of female beauty and body image has been well documented. However, few published studies have observed ethnic differences in physiological stress reactivity that may occur from pressures to comply with a particular image of beauty. This study examined whether the exposure to the mainstream ideal body image would negatively affect Latina women’s physiological and psychological functioning, and how their responses differed in comparison to their White counterparts. Participants included college-aged female students from Pitzer College who self-identified as Latina or Caucasian. Participants completed questionnaires assessing, body esteem (MSBRQ-AS; SATAQ; CDFRS), ethnic identity …
