The Genetic Epidemiology Of Purging Disorder, Anorexia Nervosa, And Obsessive Compulsive Personality Disorder, Sara Trace

Theses and Dissertations

Although a variety of factors influence the development of eating disorders, genetic factors contribute notably to their etiology. Understanding genetic factors associated with eating disorders is important, as they can influence how these disorders are recognized, researched, and treated. This dissertation included two studies addressing important questions within the fields of eating disorders and genetics; specifically, Study 1 addressed the prevalence and heritability of purging and purging disorder in a population-based sample of female twins from the United States; and Study 2 investigated the nature of the co-morbidity between anorexia nervosa and obsessive compulsive personality disorder in a population-based sample …

A Phenomenological Study Of Clinicians Treating Traumagenic Compulsions Resulting From Childhood Sexual Abuse, Albert Sarno

Faculty Dissertations

Various types of traumatic compulsive behaviors have been observed by practicing mental health clinicians and yet there is a lack of consensus among such clinicians for treating people in such a problematic state when there is also a history of childhood sexual abuse. Ten seasoned clinicians, each with over 15 years experience in treating patients with traumagenic compulsions and childhood sexual abuse were interviewed to explore their lived experience treating people with traumagenic compulsions due to childhood sexual abuse. A phenomenological design was used to asses the data collected in the study. The data were analyzed to determine the best …

An Examination Of Love And Marital Satisfaction In Long-Term Marriages, Rebeca Isabel Estrada

Electronic Theses and Dissertations

There has been little marital research that focuses on contributing factors to successful long-term marriage and even less focus on the role that love plays in long-term marriage. As a means of furthering this research, the purpose of the current study was to examine levels of satisfaction in couples in long-term marriages and to identify contributing factors to an enduring marriage. This study also examined the significance of love and changes in love after 35+ years of marriage. Through the use of qualitative methodology five couples who were self-identified as "happy" in their marriage and who had been married at …

The Sense Of Smell And Its Effect On Attraction, Grant Perkins

Undergraduate Psychology Research Methods Journal

The effect of cologne/perfume on attractiveness was examined, as well as the differences between the effect of cologne/perfume and sex. Twenty-seven participants ranging from 18-22 years of age were recruited for the experiment. The purpose of this study was to determine if putting cologne/perfume on an individual will make that person more attractive to the opposite sex than if he/she did not put on cologne/perfume. The rationale behind this is that there are a lot of advertisements about cologne and perfume that portray the people in the advertisements as more desirable after he/she sprays cologne on their skin. The hypothesis …

Mapping Quantitative Trait Loci For Feed Consumption And Feeding Behaviors In A White Duroc × Chinese Erhualian Resource Population, Z. Y. Zhang, J. Ren, Dongren Ren, J. W. Ma, Y. M. Guo, L. S. Huang

Psychology Faculty Publications

To identify QTL for feed consumption and feeding behavior traits in pigs, ADFI, feed conversion ratio (FCR), number of visits to the feeder per day (NVD), and average feeding rate (AFR) were recorded in 577 F₂ animals from a White Duroc × Chinese Erhualian resource population during the fattening period of 120 to 240 d. A whole genome scan was performed with 183 microsatellites covering the pig genome across the entire resource population. A total of 8 QTL were identified on 5 pig chromosomes, including 3 genome-wide significant QTL for FCR on SSC2, 7, and 9, 1 significant QTL …

Incarcerated Male Adolescent Suicide In Utah: A Case Study, Kristy Straubhaar

Theses and Dissertations

Adolescent suicide has been described as a major public health problem calling for the aid of researchers willing to better identify factors related to suicide risk. Suicide is the third-leading cause of death for 15 to 24 year olds. Despite the fact incarcerated adolescents act in self-destructive ways, minimal research has focused on suicide behavior among incarcerated adolescents. Existing data indicates that suicide among adolescent males is especially prevalent in the juvenile justice system. Several variables have been identified as risk factors for suicidal behavior, including interpersonal relationship dysfunction, substance abuse, and psychological variables such as depression and dichotomous thinking. …

Pain Perception In Fish: Indicators And Endpoints, Lynne U. Sneddon

Aquaculture Collection

Recent evidence has shown that fish display aversive behavioral and physiological reactions and a suspension of normal behavior in response to noxious stimuli that cause pain in other animals and humans. In addition to these behavioral responses, scientists have identified a peripheral nociceptive system and recorded specific changes in the brain activity of fish during noxious stimulation. As a result of these observations teleost fish are now considered capable of nociception and, in some opinions, pain perception. From both an experimental and an ethical perspective, it is important that scientists be able to assess possible pain and minimize discomfort that …

Octopus Insularis (Octopodidae), Evidences Of A Specialized Predator And A Time-Minimizing Hunter, Tatiana S. Leite, Manuel Haimovici, Jennifer A. Mather

Sentience Collection

Shallow-water octopuses have been reported as major predators of motile species in benthonic marine communities, capturing their prey by different foraging techniques. This study assessed for the first time the feeding ecology, foraging behavior, and defensive strategy during foraging, including the use of body patterns, to construct a general octopus foraging strategy in a shallow water-reef system. Octopus insularis was studied in situ using visual observations and video recordings. The diet included at least 55 species of crustaceans (70%), bivalves (17.5%), and gastropods (12.5%); however, only four species accounted for half of the occurrences: the small crabs Pitho sp. (26.8%) …

Rationality And Humanity: A View From Feminist Economics, Julie A. Nelson

Economics Faculty Publication Series

DOES RATIONAL CHOICE THEORY (RCT) HAVE SOMETHING IMPORTANT to contribute to the humanities? Usually the arguments for answering “yes” to this question go something like the following: The application of RCT has proved to be a powerful tool in economics and the social sciences, leading to clear and rigorous insights unattainable from less precise methods. Therefore, by also harnessing this power, the disciplines in the humanities could advance toward becoming more elegant, rational, and forceful in their explorations of human behavior. As an economist, I’d like to address this argument on its home ground. Has the use of RCT advanced …

Egfr May Couple Moderate Alcohol Consumption To Increased Breast Cancer Risk, Christopher P. Mill, Julia Chester, David J. Riese Ii

Department of Psychological Sciences Faculty Publications

Alcohol consumption is an established risk factor for breast cancer. Nonetheless, the mechanism by which alcohol contributes to breast tumor initiation or progression has yet to be definitively established. Studies using cultured human tumor cell lines have identified signaling molecules that may contribute to the effects of alcohol, including reactive oxygen species and other ethanol metabolites, matrix metalloproteases, the ErbB2/Her2/Neu receptor tyrosine kinase, cytoplasmic protein kinases, adenylate cyclase, E-cadherins, estrogen receptor, and a variety of transcription factors. Emerging data suggest that the epidermal growth factor receptor (EGFR) tyrosine kinase may contribute to breast cancer genesis and progression. Here we integrate …

Deep Rationality: The Evolutionary Economics Of Decision Making, Douglas T. Kenrick, Vladas Griskevicius, Jill M. Sundie, Norman P. Li, Jessica Yexin Li, Steven L. Neuberg

Research Collection School of Social Sciences

What is a “rational” decision? Economists traditionally viewed rationality as maximizing expected satisfaction. This view has been useful in modeling basic microeconomic concepts, but falls short in accounting for many everyday human decisions. It leaves unanswered why some things reliably make people more satisfied than others, and why people frequently act to make others happy at a cost to themselves. Drawing on an evolutionary perspective, we propose that people make decisions according to a set of principles that may not appear to make sense at the superficial level, but that demonstrate rationality at a deeper evolutionary level. By this, we …

Response To Displaced Neighbours In A Territorial Songbird With A Large Repertoire, Elodie F. Briefer, Thierry Aubin, Fanny Rybak

Ethology Collection

Neighbour recognition allows territory owners to modulate their territorial response according to the threat posed by each neighbour and thus to reduce the costs associated with territorial defence. Individual acoustic recognition of neighbours has been shown in numerous bird species, but few of them had a large repertoire. Here, we tested individual vocal recognition in a songbird with a large repertoire, the skylark Alauda arvensis. We first examined the physical basis for recognition in the song, and we then experimentally tested recognition by playing back songs of adjacent neighbours and strangers. Males showed a lower territorial response to adjacent neighbours …

Emotional Behavior In Subclinical Psychopathy, Kristen Lee Godenick

Loma Linda University Electronic Theses, Dissertations & Projects

The unique interpersonal qualities of individuals who fall on the so-called ‘psychopathic spectrum’ have been regularly documented since Cleckley’s observations (1941). The literature reflects the importance of understanding individuals who have high and low levels of psychopathic personality traits for research (Lilienfeld, 1998, Patrick, Edens, Poythress, Lilienfeld & Benning, 2006), clinical (Patrick, Hicks, Blonigen & Krueger, 2003) and risk assessment purposes (Skeem, Poythress, Edens, Lilienfeld & Cade, 2003) through bringing forth the position that psychopathic traits can fall on a continuum (Benning, Patrick, Salekin & Leistico, 2005). The purpose of this study was to investigate the association between psychopathic personality …

47-Channel Burst-Mode Recording Hydrophone System Enabling Measurements Of The Dynamic Echolocation Behavior Of Free-Swimming Dolphins, Josefin Starkhammar, Mats Amundin, Johan Nilsson, Stan A. Kuczaj, Monica Almqvist, Hans W. Persson

Faculty Publications

Detailed echolocation behavior studies on free-swimming dolphins require a measurement system that incorporates multiple hydrophones (often > 16). However, the high data flow rate of previous systems has limited their usefulness since only minute long recordings have been manageable. To address this problem, this report describes a 47-channel burst-mode recording hydrophone system that enables highly resolved full beamwidth measurements on multiple free-swimming dolphins during prolonged recording periods. The system facilitates a wide range of biosonar studies since it eliminates the need to restrict the movement of animals in order to study the fine details of their sonar beams.

Sexual Risk Recognition Deficits: The Role Of Prior Victimization And Emotion Dysregulation, Kate L. Walsh

Department of Psychology: Dissertations, Theses, and Student Research

Recent theoretical writings suggest that the ineffective regulation of negative emotional states may reduce the ability of women to detect and respond effectively to situational and interpersonal factors that increase risk for sexual assault. However, little empirical research has explored this hypothesis. In the present study, it was hypothesized that prior sexual victimization and negative mood state would each independently predict poor risk recognition and less effective defensive actions in response to an analogue sexual assault vignette. Further, these variables were expected to interact to produce particularly impaired risk responses. Finally, that the in vivo emotion regulation strategy of suppression …

Rules For Becoming A Graceful Woman: Rhetorical Analysis Of The Japanese Self-Help Book Grace Of Women, Kaori Yamada

UNIversitas: Journal of Research, Scholarship, and Creative Activity

People buy and read books to gain something they lack in their lives. One might read a novel to have fun, one might read a philosophy book to rethink his/her worldview, or one might read a how-to book to learn an easy process for self-improvement. Self-help books, in particular, are explicit instruction manuals for achieving personal and relational well being (Zimmerman, Holm, and Haddock 122). By analyzing popular self-help books, one can discover what people believe they might be lacking.

Modulation Of Long-Term Memory By Arousal In Alexithymia: The Role Of Interpretation, Kristy A. Nielson, Mitchell A. Meltzer

Psychology Faculty Research and Publications

Moderate physiological or emotional arousal induced after learning modulates memory consolidation, helping to distinguish important memories from trivial ones. Yet, the contribution of subjective awareness or interpretation of arousal to this effect is uncertain. Alexithymia, which is an inability to describe or identify one’s emotional and arousal states even though physiological responses to arousal are intact, provides a tool to evaluate the role of arousal interpretation. Participants scoring high and low on alexithymia (N = 30 each) learned a list of 30 words, followed by immediate recall. Participants then saw either an arousing (oral surgery) or neutral video (tooth …

Profiles Of Drug Endangered Children: Investigation In A Clinical Sample, Imanie Samanmali Wijayaratne

Loma Linda University Electronic Theses, Dissertations & Projects

Despite the increase in children born prenatally exposed to methamphetamine, little is known about the cognitive and neuropsychological outcomes of these children. Research specific to prenatal-methamphetamine exposure is extremely limited and has been primarily restricted to rat studies. This research combined with the few studies examining children prenatally exposed to methamphetamine suggests that methamphetamine-exposure is associated with various cognitive and neuropsychological delays and is impacted by both biological and environmental factors. Given the scarcity of research in this area, the current study used archival data from a psychological assessment clinic to (1) describe the frequency of prenatal methamphetamine-exposure cases, (2) …

Why Was I Rejected? How The Attributed Reason For Social Rejection Impacts Subsequent Behavior., Brian Curtis Nelson

Electronic Theses and Dissertations

It is proposed that differences in rejection attribution could yield variations in subsequent prosocial behavior. To test the attribution hypothesis, 109 participants were randomly assigned to a performance based rejection, a personally based rejection, or a control condition and then worked with an ostensible partner via the Internet to develop uses for a common household item. Prosocial behavior was measured by the number of uses a participant generated (working harder for the team). When generating creative uses, participants in the rejection conditions performed significantly worse than nonrejected participants (F(2,74) = 4.576, p<.05, r²=.11). However, in contradiction …

The Formation Of "Outsider" Through Labeling And Sentence Lengths For Immigrants Of Hispanic Descent., Jeremy Jason Smith

Electronic Theses and Dissertations

The purpose of this study was to determine if individuals who supported denying citizenship to children of foreign parentage and making English the sole language spoken in the United States held the opinion that a sentence length over 15 years was appropriate for non-U.S. individuals. Other purposes were to determine if individuals with high religiosity or who carried a lethal weapon also held the opinion that a sentence length over 15 years was appropriate for non-U.S. individuals.

Pearson's Chi-Square was used to determine if a significant relationship existed between the independent variables and the dependent variable. The data indicated that …

Probing Predispositions: The Pragmatism Of A Process Perspective, David S. Moore

Pitzer Faculty Publications and Research

As J. P. Spencer et al. (2009) argue, the theories of some developmental psychologists continue to be nativistic, even though nativism is an inherently nondevelopmental school of thought. Psychologists interested in development study the emergence of human characteristics—including predispositions—and are not content to simply catalogue competences that characterize human newborns; instead, they recognize that all human characteristics, including those present at birth, reflect the circumstances of development. A truly developmental science of behavior requires rejecting the nativism–empiricism debate outright, abandoning ideas such as “core knowledge” and psychological “endowments,” and adopting a process perspective that focuses on how traits emerge from …

Stimulus Type, Level Of Categorization, And Spatial-Frequencies Utilization: Implications For Perceptual Categorization Hierarchies, Assaf Harel, Shlomo Bentin

Psychology Faculty Publications

The type of visual information needed for categorizing faces and nonface objects was investigated by manipulating spatial frequency scales available in the image during a category verification task addressing basic and subordinate levels. Spatial filtering had opposite effects on faces and airplanes that were modulated by categorization level. The absence of low frequencies impaired the categorization of faces similarly at both levels, whereas the absence of high frequencies was inconsequential throughout. In contrast, basic-level categorization of airplanes was equally impaired by the absence of either low or high frequencies, whereas at the subordinate level, the absence of high frequencies had …

Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas

Master's Theses

The female rat, among other species, undergoes a fundamental brain re-modeling as a consequence of experiencing the normal and natural events of pregnancy and offspring stimulation. Compelling data show that maternal experiences produce neurobiological modifications in the female leading to specific maternal behaviors, affective states, and the basic underlying female neurobiology necessary to raise viable offspring. This study aims to evaluate the number, quality and selective activation of neurons that develop during the maternal experience. The study showed a trend toward supporting the hypothesis that a “maternal-circuit” is formed through the proliferation of neurons during late-motherhood and lactation, and is …

Microsatellite-Based Genetic Diversity And Evolutionary Relationships Of Six Dog Breeds, J.-H. Ye, Dongren Ren, A.-F. Xie, X.-P. Wu, L. Xu, P.-F. Fu, H.-A. Zhao, Q.-Y. Yang

Psychology Faculty Publications

The Tibetan Mastiff is one of the most archaic, ferocious and the largest dogs in the world. The Kunming dog is the chief working-dog breed in China. In this study, ten microsatellite loci were used to assess the genetic diversity and evolutionary relationships in six dog breeds, including Tibetan Mastiff, Kunming dog, Belgian Malinois, Labrador Retriever, English Springer Spaniel, and German Shepherd. The highest genetic diversity was exhibited by the Tibetan Mastiff, indicating useful protection and little inbreeding in the modern Tibetan Mastiff. Higher genetic diversity was observed in European breeds, supporting the hypotheses that breeders outcross their pure breed …

Narrative Theory And Fort Berthold's Stories Of The Paranormal Or Supernatural, Waylon C. Baker

Theses and Dissertations

The author collected stories of the paranormal and supernatural from 10 enrolled members of the Three Affiliated Tribes of Fort Berthold, North Dakota. The research participants were members of the Mandan, Hidatsa, and Arikara tribes. Five research questions guided the study: (1) Where did these contemporary stories of the paranormal or supernatural originate? (2) What is the meaning behind these stories? (3) How are these stories different from other stories of the paranormal or supernatural? (4) Do the respondents “believe” in these stories of the paranormal? (5) Do these stories connect to traditional American Indian customs and beliefs?

A Psychometric Evaluation Of The Revised Optimism-Pessimism Scale Of The Mmpi-2, Ginger Burge Debrule

Dissertations

The present study tested the psychometric properties of the Revised Optimism-Pessimism Scale (PSM-R) of the MMPI-2. This scale purportedly measures the respondent's explanatory style on a dimension of optimism and pessimism. Participants included 92 college undergraduates and 2,729 participants from archived outpatient data. The PSM-R is a reliable measure, based on test-retest reliability and internal consistency. However, the construct validity of the measure is questionable. Evaluation of the PSM-R items suggests that the items are not all related to the optimism-pessimism construct. In addition, convergent validity of the PSM-R was assessed using measures of attributional style, dispositional optimism, hope, depression, …

The Effect Of Holland's Person-Environment Fit On Trait Anger, Interpersonal Conflict At Work, And Workplace Aggression, Aimee Chantelle Pseekos

Dissertations

This study examined the effect of Person-Environment fit, as defined by Holland's (1997) theory, on trait anger, interpersonal conflict at work, and workplace aggression in a sample of employees in the United States. Job satisfaction was also examined with regard to concurrent and discriminant validity information for this sample. Results indicated that there was not a statistically significant effect of Person- Environment fit on trait anger, interpersonal conflict at work, or workplace aggression. The concurrent and discriminant validity of findings was supported through relationships between job satisfaction, Person-Environment fit, and workplace aggression. Limitations and implications for further research related to …

Effects Of Selection For Cooperation And Attention In Dogs, Márta Gácsi, Paul Mcgreevy, Edina Kara, Ádám Miklósi

Cooperative Behavior Collection

Background: It has been suggested that the functional similarities in the socio-cognitive behaviour of dogs and humans emerged as a consequence of comparable environmental selection pressures. Here we use a novel approach to account for the facilitating effect of domestication in dogs and reveal that selection for two factors under genetic influence (visual cooperation and focused attention) may have led independently to increased comprehension of human communicational cues.

Method: In Study 1, we observed the performance of three groups of dogs in utilizing the human pointing gesture in a two-way object choice test. We compared breeds selected to work while …

How Selected Personality Factors Affect The Relationships Between Marital Satisfaction, Sexual Satisfaction, And Infidelity, Amanda Marie Campbell

Doctoral Dissertations

Although research has illuminated some differences between those who engage in sexual behavior outside of their marriage and those who do not, there is a lack of attention in the literature to complex interactions among variables in their relationships to infidelity. There is evidence that marital satisfaction, sexual satisfaction, and personality are all related to infidelity but research has failed to investigate how personality may influence these other two variables in their relationship to infidelity. Thus, the proposed study explored possible effects that selected personality factors have on the relationships between marital satisfaction, sexual satisfaction, and infidelity. The results revealed …
