Frequency-Specificity And Pattern-Specificity Of The Buildup Of Auditory Stream Segregation, David Michael Weintraub

UNLV Theses, Dissertations, Professional Papers, and Capstones

During repeating sequences of low (A) and high (B) tones in an "...ABAB..." pattern, the likelihood of hearing two separate streams ("streaming") increases with more repetitions of the patterns, a phenomenon referred to as "buildup". Previous studies have shown that buildup is frequency specific (Anstis & Saida, 1985) and that its biasing effects decays over several seconds (Beauvois & Meddis, 1997). No study has examined whether the frequency specificity of buildup persists for such a long duration. To address these issues, Experiment 1 tested the decay of frequency-specific and non-frequency specific buildup. The results revealed that (1) frequency-specific buildup effects …

Affect Identification And Interpersonal Skills: An In-Depth Evaluation Of Social Cognition In Schizophrenia, Griffin Pollock Sutton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The presence of deficits in various sub-domains of social cognition has been investigated to a degree in individuals with schizophrenia. Some of the most commonly researched and documented deficits have included impairments in the identification of affect portrayed in faces. Research has indicated that the performance of individuals with schizophrenia on such tasks is generally impaired as compared to normal controls. However, some have questioned the generalizability of such findings to real-world situations, as day-to-day interactions generally necessitate a constant, fluid assessment of the thoughts and feelings of others and are rarely, if ever, limited to still images of others. …

Research Brief: "Protective Factors And Risk Modification Of Violence In Iraq And Afghanistan War Veterans", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This research studies non-combat related aggressive behavior in service members and the influence of protective factors. Veterans with protective factors, such as having positive social support, are less likely to engage in violence, and therefore expanding social support programs are beneficial. Future research should consider exploring various components of work life in relation to potential aggression.

Building Trust And Collaboration With Rural Minorities: Experiences With Minority Farmers In The Mississippi Delta, Ari Mwachofi

Journal of Health Disparities Research and Practice

The paper focuses on the question “What research approach is effective in building trust with minority farmers?” The question is answered through a documentation of researchers’ experiences building trust and collaboration with minority farmers in the lower Mississippi Delta. The researchers applied two research paradigms -logical positivism and paradigm of praxis. The logical positivism research approach was met with mistrust and open animosity and had to be abandoned for one based on the paradigm of praxis. Through this approach, and cognizant of the historical-social-political context, the researchers included insiders from the focus population as collaborators and researchers and succeeded in …

Transformation Of Stimulus Function Through Relational Networks: The Impact Of Derived Stimulus Relations On Stimulus Control Of Behavior, Samantha Rose Florentino

USF Tampa Graduate Theses and Dissertations

Relational Frame Theory research involves either of two protocols utilized to establish relational networks and functions for stimuli in those relational networks. Years of research indicate the most prevalent method involves first establishing a relational frame, conditioning one of the stimuli to acquire a particular function, and then providing a test to see if the function trained to one of the stimuli in the network transferred through the relational network to other stimuli. The less common method involves first training a particular function for a stimulus, entering that stimulus in a relational network with at least two other stimuli, and …

Psychotherapy Clients’ Online Behavior And Opinions Regarding Internet Searches Conducted By Therapists, Emily B. Gale

Department of Psychology: Dissertations, Theses, and Student Research

The Internet has become possibly the most popular medium to find information and communicate in our society. For the field of psychology, the Internet offers a new way to collect data and communicate with both study participants and, for practicing psychologists, possibly clients. Little is known, however, about the implications of interacting with clients online. The existing empirical studies in this area (DiLillo & Gale, 2011; Lehavot, Barnett, & Powers, 2010; Taylor et al., 2010) have focused on psychology graduate students’ actions online. These studies highlight the importance and paucity of research regarding the online behaviors of psychotherapy clients and …

Effects Of Gender Composition Of Target And Sender Dyads On The Tendency To Infer Lies, Byron J. Simoneaux

Doctoral Dissertations

Lying is so common in human behavior that some have labeled it a social skill. Despite the ubiquity of lies, humans have consistently been found to be poor lie detectors. Attempts have been made to improve the accuracy of human lie detection. Unfortunately, the most successful training only improves accuracy slightly above the level of chance. Because of its importance to society, considerable effort has been aimed at developing methods to help determine when people are lying. Researching how and why humans infer that another person is lying has the potential to advance the understanding of lie detection. Researchers have …

Autism Spectrum Disorders In Hispanics And Non-Hispanics, Virginia Chaidez, Robin L. Hansen, Irva Hertz-Picciotto

Department of Nutrition and Health Sciences: Faculty Publications

Objectives: To compare differences in autism between Hispanics and non-Hispanics. We also examined the relationship between multiple language exposure and language function and scores of children. Methods: The Childhood Autism Risks from Genetics and the Environment (CHARGE) study is an ongoing population-based case-control study with children sampled (n = 1061) from three strata: those with autism (AU) or autism spectrum disorder (ASD); developmental delay (DD); or the general population (GP). Results: Non-Hispanic cases demonstrated higher cognitive composite scores for the Mullen Scales of Early Learning (MSEL). There were significant associations between multiple language exposure and MSEL subscales for receptive …

The purpose of the current study is to ascertain the presence of posttraumatic stress disorder in veterans returning from Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF), and Operation New Dawn (OND), the potential impairment in their abilities to cope with the combat-related stress. The …

The Relationship Between Self-Reported Cancer Pain And Personality In Black And White Older Adults Receiving Outpatient Cancer Care, Jessica Krok

USF Tampa Graduate Theses and Dissertations

It is well-established that personality not only affects physical health and longevity, but also mental health and coping mechanisms. One area of limited research is the relationship between cancer pain and personality. This study examined how personality traits affect reported cancer pain severity in older patients (N = 150) receiving outpatient treatment at a comprehensive cancer center. Participants were interviewed regarding their pain severity, personality, affect, and self-efficacy for pain management. Symptom data were collected from the Brief Pain Inventory, while personality data were gathered from the Ten Item Personality Inventory and the Positive and Negative Affect Schedule. Self-efficacy for …

Relationships Between Social Self-Esteem, Media Influence And Drive For Thinness, Sofia Fernandez, Mary E. Pritchard

Psychological Sciences Faculty Publications and Presentations

Although media exposure is known to relate to drive for thinness and social self-esteem in women, less is known about how media affects drive for thinness and social self-esteem in men. The present study examined the relationships between drive for thinness, social self-esteem, and media influence among men and women. Two hundred ninety-four college students completed the Texas Social Behavior Inventory, the Sociocultural Attitudes towards Appearance Scale-3, a self-constructed questionnaire measuring the influence of media models, and the Drive for Thinness scale of the EDI-3. We expected to find an association between drive for thinness and media influence and between …

Cyberspace And Real-World Behavioral Relationships: Towards The Application Of Internet Search Queries To Identify Individuals At-Risk For Suicide, Casey C. Miller

Theses and Dissertations

The Internet has become an integral and pervasive aspect of society. Not surprisingly, the growth of ecommerce has led to focused research on identifying relationships between user behavior in cyberspace and the real world - retailers are tracking items customers are viewing and purchasing in order to recommend additional products and to better direct advertising. As the relationship between online search patterns and real-world behavior becomes more understood, the practice is likely to expand to other applications. Indeed, Google Flu Trends has implemented an algorithm that accurately charts the relationship between the number of people searching for flu-related topics on …

An Evaluation Of The Implementation Of "The Happiest Toddler On The Block" Parenting Strategies By Young Mothers, Amye Elizabeth Bock

USF Tampa Graduate Theses and Dissertations

Young parents and their children are considered a high-risk population as they are more likely to lack social support networks, have limited access to opportunities to enhance parenting skills, and are often financially dependent. Young children whose mothers have poor parenting skills are more likely to have persistent problem behavior. Three young mothers living in a transitional housing facility participated in this study. The purpose of this study was to determine if these mothers could implement parenting strategies that are a part of a commercially available parenting book and DVD. This study found that: (1) mothers were able to correctly …

Training And Assessment Of Toothbrushing Skills Among Children With Special Needs, Rachel A. Brown

USF Tampa Graduate Theses and Dissertations

The success of applied behavior analysis (ABA) interventions relies heavily on adherence to measures of social importance. One area identified by caregivers, educators, and researchers as having social importance is the area of daily living skills; particularly in populations of children with special needs. A number of studies employed the use of a task analysis to objectively measure toothbrushing, with various training procedures utilized. Behavioral Skills Training (BST) is an effective procedure used to train a variety of skills. Further, research indicates the addition of an in situ assessment promotes generalization of trained skills. The current study examined the use …

Greater Benefits Of Multisensory Integration During Complex Sensorimotor Transformations., Verena N Buchholz, Samanthi C Goonetilleke, W Pieter Medendorp, Brian D Corneil

Brain and Mind Institute Researchers' Publications

Multisensory integration enables rapid and accurate behavior. To orient in space, sensory information registered initially in different reference frames has to be integrated with the current postural information to produce an appropriate motor response. In some postures, multisensory integration requires convergence of sensory evidence across hemispheres, which would presumably lessen or hinder integration. Here, we examined orienting gaze shifts in humans to visual, tactile, or visuotactile stimuli when the hands were either in a default uncrossed posture or a crossed posture requiring convergence across hemispheres. Surprisingly, we observed the greatest benefits of multisensory integration in the crossed posture, as indexed …

Resting-State Connectivity Identifies Distinct Functional Networks In Macaque Cingulate Cortex., R Matthew Hutchison, Thilo Womelsdorf, Joseph S Gati, L Stan Leung, Ravi S Menon, Stefan Everling

Brain and Mind Institute Researchers' Publications

Subregions of the cingulate cortex represent prominent intersections in the structural networks of the primate brain. The relevance of the cingulate to the structure and dynamics of large-scale networks ultimately requires a link to functional connectivity. Here, we map fine-grained functional connectivity across the complete extent of the macaque (Macaca fascicularis) cingulate cortex and delineate subdivisions pertaining to distinct identifiable networks. In particular, we identified 4 primary networks representing the functional spectrum of the cingulate: somatomotor, attention-orienting, executive, and limbic. The cingulate nodes of these networks originated from separable subfields along the rostral-to-caudal axis and were characterized by positive and …

Enhancing Male Hpv Vaccine Acceptance: The Role Of Altruism And Awareness Of Male Specific Health Benefits, Katherine Bonafide

Psychology - Theses

While considerable research exists on female HPV vaccine acceptance, research is needed to clarify factors that facilitate vaccine uptake among boys and men. The benefits of male HPV vaccination exist on an individual and community level. Male HPV vaccination provides personal health protection to recipients, and can provide female health protection by minimizing transmission of HPV to sexual partners. As such, male vaccine acceptance may be enhanced by emphasizing both altruistic motives (female health protection) and personal health benefits. A sample of college-age men (N = 200; M age = 19.3; 31% Non-White) completed computer-administered surveys and were presented with …

The Association Of Diet With Affect, Patricia Ann Ford

Loma Linda University Electronic Theses, Dissertations & Projects

Nutrients such as omega-3 fatty acids have been associated with mental health yet few studies have examined whether foods protective or deleterious for cardiovascular disease affect mood. The purpose of this study was to examine associations between consumption of foods typical of Mediterranean and Western diets and fatty acids with positive and negative affect.

Adventist church attendees residing in North America completed a validated food frequency questionnaire in 2002-6 as part of the Adventist Health Study-2. A subset of these participants ^=9,121) completed the Positive and Negative Affect Schedule (PANAS) in the Biopsychosocial Religion and Health Study conducted in 2006-7. …

The Role Of Engagement Across Conceptually Distinct Treatment Elements For Social Anxiety Disorder, Timothy M. Emge

Department of Psychology: Dissertations, Theses, and Student Research

There are currently several efficacious treatments for social anxiety disorder (e.g. exposure therapy and cognitive therapy). Each of these treatments is thought to reduce symptoms of social anxiety by disrupting maintenance mechanisms of the disorder, yet mechanism of change research has not supported this view. The current study compared components from each therapy modality in order to better understand why symptoms reduce similarly between conceptually distinct treatments. Participants with high social anxiety were randomly assigned to give a speech with cognitive restructuring and engagement-enhancing procedures, cognitive preparation and video feedback, or a speech alone. Self-ratings of speech performance, confidence in …

Dimensions Of Individuals' Judgements About Sexual Attraction, Romantic Attachment, And Sexual Orientation, Luis F. Morales Knight

Department of Psychology: Dissertations, Theses, and Student Research

Despite 150 years of scientific interest in sexual orientation, contemporary investigators grapple with a number of serious difficulties. A precise, unified definition of sexual orientation appropriate for scientific use continues to elude researchers, most likely because there is still no single coherent theory of sexual orientation. This lack impedes research into the measurement of sexual orientation. Existing measurements of sexual orientation rely on partial or incompletely empirical research. The present study identified promising avenues for development of credible definitions, theories, and measurements of sexual orientation: (a) mate-selection tasks; (b) the idea that bisexually-identified individuals place a lower priority on partner …

Lesbian/Queer/Same-Gender-Loving Women Graduate Students In Mental Health Related Fields: A Grounded Theory Of Attitudes Toward Transgender Individuals, Bonnie M. Benson

Dissertations

Transgender (trans) issues are an emerging area of research within counseling psychology. As such, little is known about how individuals form their attitudes toward trans people. Despite evidence that lesbian women are one group that has held biased views of the trans population, the literature has not addressed the perceptions that lesbian women have of trans individuals. Furthermore, the campus climate literature has attended to how LGBT students experience campus discrimination, but this literature has not addressed within-group differences, that is, attitudes and interactions among LGBT members of a university community, such as those between lesbians and trans people. The …

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 …

Linguistic Devices, Emotionality, And Memorability Of Computer Mediated Communication, Angela M. Mion

Undergraduate Honors Thesis Collection

I examined whether college students use shortcuts, pragmatics, and errors in text messages differently depending on their gender and the emotionality of the message. Results indicate that the prevalence of particular shortcuts differed across happy, sad, and angry messages, but gender did not influence use of linguistic devices. In a second study, I examined the emotionality and memorability of text messages versus voicemails. Results indicate that texts may be remembered better than voicemails, and happy, sad, and angry messages may be remembered differently by men and women.

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 …

Pharmacy And Empathy: Evaluating The Impact Of A Pharmacy Student's Project In A Service-Learning Course, Carly D'Agostino

Undergraduate Honors Thesis Collection

Background: Empathy is taking on a larger role in the pharmaceutical field as pharmacists place emphasis on patient centered care. Service-learning courses can expose pharmacy students to future patients, allowing them to interact and develop empathy. While this study suggests service-leaming can foster empathy, further research is needed to assess the specific outcome of empathy as a result of incorporating a project in a service-learning course for pre-pharmacy students.

Objective: To evaluate the effect on a pharmacy student's empathy after completing a one-on-one patient interview project during a service-learning experience. A secondary objective is to assess tile validity of a …

A Study Of The Reasons And Functions Of Non-Suicidal Self-Injury (Nssi) Among Students In Hong Kong And United Kingdom, Sze Yiu, Cindy Wong

Bachelor of Social Sciences – Senior Theses

This study examines non-suicidal self-injury (NSSI) in a community sample of adolescents and young adults in Hong Kong and United Kingdom. Non-suicidal self‐injury (NSSI) refers to direct, deliberate destruction of one’s own body tissue in the absence of intent to die. Apart from investigating the reasons and functions of non-suicidal self‐injury (NSSI), this study also examined the gender as well as cultural differences in self‐injurious behaviors. Functional Assessment of Self‐Mutilation (FASM) was used to examine non‐suicidal self-injury (NSSI).

Overall, 17.1% (n=46) out of 269 participants (n=269) endorsed engaging in non-suicidal self‐injury (NSSI) in the past 12 months, with more females …

Suicide Rates Among Young, Married Women In Nepal, Kirra L. Hughes

Capstone Collection

In 2009, a Maternal Mortality and Morbidity (MMM) report carried out in Nepal by the Family Health Division of the Department of Health Services accidently stumbled upon a surprising leading cause of death in Nepali women of reproductive age (15 - 49). The result: suicide. And the numbers are still on the rise. There have since been no comprehensive follow-up studies and none, to my knowledge, that are currently ongoing. This leaves an urgent need for research to be done on the causes of these suicides (Benson and Shakya, 2011; Bertolote et al, 2005; Pradhan et al, 2009).

Globally, there …

Individualism And Collectivism As Moderators Of Affect And Attributional Style In Predicting Life Satisfaction, Jo M. Holmquest

Graduate Theses

The present study examined the effect of person-level individualism and collectivism on attributional style and frequencies of positive and negative emotions as predictors of life satisfaction. Participants were 224 individuals (age range 18 to 78, M= 39.63, SD = 13.78; 73% women; 56% Filipinos) who answered an online survey. Results from regression analyses showed that attributional style is not a statistically significant predictor of life satisfaction. The analyses also showed that across all participants, and among those who did not score high in individualism and low in collectivism, the frequency of positive emotions, as compared to the frequency of negative …
