Debrazza’S Monkeys (Cercopithecus Neglectus) In A Mixed-Taxa Zoo Exhibit: Effects On The Behavior Of A Breeding Group Of Debrazza’S Monkeys After The Birth Of An Infant, Rachel Diamond
Psychology Honors Projects
Historically, zoos rarely feature mixed taxa exhibits including multiple primate species; the Minnesota Zoo opened such a unique four-species exhibit featuring Rock hyraxes, Red River hogs, Colobus monkeys, and DeBrazza’s monkeys in May, 2010. Because of potential problems associated with territoriality and aggression, primates in mixed-taxa exhibits are generally non-breeding. However, the DeBrazza’s monkeys at the MN Zoo are a breeding pair with a juvenile offspring. The intent of this study was to design an ethogram with the purpose of calculating the effects of a mixed taxa exhibit on the behavior of this breeding group, and to compare their behavior …

Persistence Of One-Trial Cocaine-Induced Behavioral Sensitization And Conditioned Activity In Preweanling Rats, Anthony Michael Cortez
Theses Digitization Project
The purpose of this thesis was to determine the persistence of one-shot context-specific and context-independent behavioral sensitization by administering a single pretreatment injection of cocaine or saline in either the home cage or a novel test chamber on PD 19 or PD 79. In order to examine the persistence of conditioned activity, adult rats were given an injection of saline after 1, 3, or 5 abstinence days. Preweanling rats were given an injection of saline after only 1 abstinence day.

Medial Prefrontal Modulation Of The Nucleus Basalis Magnocellularis During Attention-Dependent Learning, Venuz Yadira Greenfield
Theses Digitization Project
The nucleus basalis magnocellularis (NBM) sends cholinergic projections to the neocortex. While NBM activation of the neocortex regulates attention and contributes to memory formation, the mechanisms controlling NBM activity during attention-dependent learning are not well understood. The current experiment tested the hypothesis that the mPFC is critically involved in modulating NBM activity during attention-dependent learning in rats. A total of 80 male Long-Evans rats were purchased from a commerical research animal vendor. Rats were randomly assigned to one of four controlled groups. The procedures were done by an animal technician and veterinarian in the CSUSB Social and Behavioral Science vivarium …

Roles Of Internal Locus Of Control And Self-Efficacy On Managing Job Stressors And Ryff's Six Scales Of Psychological Well-Being, William A. Howatt
Walden Dissertations and Doctoral Studies
The purpose of this study was to investigate the roles internal locus of control and self-efficacy play in moderating how employees manage their perceived work stress and positively engage in the behaviors that facilitate autonomy, environmental mastery, personal growth, self-acceptance, positive relations with others, and purpose in life. Investigators have documented the relationship between perceived workplace stress and strain and showed that how employees cope with perceived stress influences their psychological and physical health. However, there is less information available about the relationship between how employees cope with perceived workplace stress and engage in behaviors that facilitate their psychological well-being. …

Self-Hypnosis And Volitional Control Of Finger Temperature Among Adults, Joseph Swope
Walden Dissertations and Doctoral Studies
Raynaud's disease is a condition in which circulation to the hands becomes restricted, causing an uncomfortable sense of cold and occasionally injury. The cause of Raynaud's disease is unknown. Earlier studies have shown that hetero-hypnosis is effective in the treatment of Raynaud's disease. Cost and access to providers limit such a treatment's availability. Theories of hypnosis suggest that self-hypnosis underlies all hypnotic processes. This study examined the utility of self-hypnosis and focused attention on the volitional control of hand temperature. Forty-three adult participants ranging in age from 19 to 77 years with no hypnosis experience were randomly divided into 2 …

The Relationship Between Depression And Cognitive Deterioration In Older Adults, Rakesh Chand
Walden Dissertations and Doctoral Studies
The population structure of the United States is changing; the older age group is increasing in size relative to the younger generation. The trend is expected to continue, especially starting in 2020, when the baby boomer population---estimated at 80 million---will be reaching their 65 th birthday, a time associated with increasing health complications, including depression and dementia. The study employed a holistic paradigm as the conceptual framework to examine the association between depression and dementia in older adults, and generated a grounded theory to illuminate the relationship between depression and dementia. This theory was then used to assess the efficacy …

U.S. and world communities face the challenges of understanding how children grieve and of giving them sufficient social and educational support. Inner-city minority adolescents have not been represented well in the bereavement and attachment literature. The purpose of the quantitative study was to use the attachment theory to understand the impact of parental bereavement on these adolescents. Data were collected using the Adult Attachment Interview (AAI), the Piers-Harris Children's Self- Concept Scale (2nd ed.), and school records. MANOVAs were used to analyze the influence of attachment organization, bereavement status, and gender on self-concept and academic and behavioral functioning in school. …

Spirituality And Depression In Parents With Children In Oncology Or Hematology Treatment, Kurt D. Soell
Walden Dissertations and Doctoral Studies
The psychological burden of cancer treatment affects not only child patients but also their parents. There is extensive literature on the positive influence of spirituality on the cancer patient. But there is a gap in the literature on the potential healing influence of spirituality on the parent of the cancer or hematology patient. The purpose of this study was to examine the relationship between spirituality and parents' levels of depression and anxiety during their child's hematological or oncology treatment. Using the transtheoretical model of change, a purposive sample of 48 parents of children undergoing cancer or hematology treatment completed a …

Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy
Dissertations
Research has shown that acute drug administration may affect impulsivity (i.e., choice for small, immediate rewards over large, delayed rewards) on laboratory delay-discounting tasks. Few studies have investigated how drug abstinence affects impulsivity. Investigating how drug abstinence affects impulsivity may be relevant to preventing relapse. Two previous studies have investigated the effects of short-term nicotine abstinence on impulsivity using delay-discounting tasks. The results were mixed, one study suggested that choices became more impulsive (i.e., delayed money was devalued) under nicotine deprivation. One goal of the present research was to further investigate how nicotine deprivation affects delay-discounting for money rewards. In …

Sex-Typical Body Shape, Quality Indicators And Behaviors, Kyungok Sim
Legacy Theses & Dissertations (2009 - 2024)
According to evolutionary theory, sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation in reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate selection. The purpose of this study was to investigate whether sex-typical body shape predicts individual variation in morphological traits that signal quality [fluctuating asymmetry (FA), hand grip strength (HGS), digit ratios (2D:4D) and leg-to-torso ratio (LTR)] and in psychological masculinity/femininity and the role of these in reproductive fitness. The results revealed that a man's masculine body shape predicted low …

The Differential Effects Of Genetic And Dietary Alterations In Folate Status On Prefrontal Cortical Functions, Jessica Amanda Ash
Legacy Theses & Dissertations (2009 - 2024)
Folate status plays an essential role in embryogenesis and brain development; however, its importance in supporting cognitive functioning throughout adulthood is less clear. The present study was interested in examining the effects of genetic and dietary alterations in folate status on prefrontal cortical functions in mice, modeling a common polymorphism in the MTHFD1 gene in folate metabolism. A factorial design was used crossing two genotypes (mice with a gene trap insertion in the Mthfd1 gene exhibiting 50% decreased Mthfd1 expression: Mthfd1gt/+ mice or wildtype mice) with two levels of dietary folate (folate sufficient or folate deficient). The mice were tested …

Features Of The Human Body And Voice : The Biological Impact On Perception And Attraction Through Multiple Sensory Domains, Roy Nathan Pipitone
Legacy Theses & Dissertations (2009 - 2024)
A growing body of literature has shown that variation in the sound of a person's voice conveys important information about our underlying biology. The present studies further investigate how the human voice can be used as a medium that disseminates characteristics related to mate quality and attraction. The human voice has been shown to be affected by cyclic hormonal fluctuations across the menstrual cycle, and raters show preferences for voice recordings at heightened fertility times compared to other times during the menstrual cycle. In the current studies, this finding was replicated multiple times and less masculine males were found to …
