Conduct Disorder (CD) is one of the most frequent reasons for a mental health referral for children and adolescents and thus constitutes the most common childhood psychiatric problem in the United States (Hill, 2002). Clinical investigations suggest that approximately two to nin…
The purpose of the current study was to determine the clinical utility of the Ohio State University Traumatic Brain Injury Identification Method (OSU-TBI-ID) in a criminal justice sample, by evaluating the criterion-related validity of this instrument. It was hypothesized that t…
Repeated exposure to addictive drugs produces neurochemical and structural adaptations in mesolimbic dopamine neurons. It is known that natural motivated behaviors (e.g. feeding, mating) also activate the mesolimbic dopamine pathway. Before the mechanisms underlying drug addicti…
The purposes of the present exploratory study with the Sudanese schizophrenic patients were to (a) determine the epidemiology and symptom structure of schizophrenic patients and (b) determine the nature of symptoms in conversion disorder patients. The findings of the schizophren…
Circadian rhythms in the Syrian hamster can be adjusted by inducing the animal to become active during its usual sleep period. This type of clock resetting is distinct from clock resetting by light, and is thus known as nonphotic phase shifting. Although the prevailing view has …
With divorce rates close to fifty percent in the United States alone, it seems imperative that future research be devoted to a deeper level of understanding regarding what constitutes marital satisfaction. In relationship to both mate selection and long term marital satisfaction…
The aim of the present study was to identify specific types of maternal psychosocial stress experienced by women of ethnic minority status (Asian, Arab, Other Asian, African, First Nations and Latino) in relation to pregnancy and infant health. A secondary analysis of variables …
The purpose of this study was to find a relationship between hypervigilance, depression and substance abuse in American Veterans of the Iraq War diagnosed with Posttraumatic Stress Disorder (PTSD). Research on hypervigilance, depression and its effects on substance abuse in Sold…
The study first defined artist's afterimage using seminal nineteenth-century writing about afterimage and painting. The authors included Goethe, who described the psychophysical characteristics of afterimage in painting; Chevreul, who recorded afterimage hues; Blanc, who publish…
An analysis of the animal rights movement's effect upon national policy concerning psychological and biomedical research was examined. The ideology, tactics, and funding sources of the movement were assessed in an effort to predict its future consequence on animal research. An e…
Mating behavior in the male Syrian hamster (Mesocricetus auratus) is dependent on chemosensory cues and gonadal steroids, and the limbic system pathways important for processing these two signals have been identified. In the experiments described in this dissertation, I have uti…
Virtually all animals experience adverse circumstances during their lifetimes. Often, it is not necessarily the events themselves, but rather the psychological appraisal of the events that determine whether a state of stress, fear or anxiety exists. The majority of studies exami…
Obesity is a major problem in the United States, especially for individuals at the extreme end of the weight scale. It has medical, social, and emotional consequences. Traditional treatments often consist of singular approaches that do not take into account the complex factors t…
This dissertation explored the hypothesis that major depressive disorder (MDD) prematurely ages the immune system and central nervous system (CNS). The first empirical chapter, Chapter 2, found that participants with a history of cytomegalovirus (CMV) infection had greater accum…
Research done by the Center for Disease Control (CDC) found that adverse childhood experiences (ACEs) such as abuse, household challenges, and neglect were linked to later health risks in life and overall well-being (CDC, 2019). Adverse experiences occur worldwide in a variety o…
African weakly discharging electric fish (of the family Mormyridae) use their self-generated electric signals and electroreceptive abilities in orientation as well as social communication. This thesis investigated short-term changes in electric organ discharge (EOD) pattern, EOD…
In this thesis, we report on studies that investigated the roles of serotonin (5-hydroxytryptamine; 5-HT) and γ-aminobutyric acid (GABA) in the pathophysiology of mania and in the mechanism of action of the mood stabilizer, divalproex sodium (DVP) using neuroendocrine challenge …
Prepubertal animals differ vastly from adults in their social behaviors. These behavioral changes during puberty must be mediated by changes in the structure and/or function of the central nervous system. In the present dissertation, the male Syrian hamster (Mesocricetus auratus…
