Attention and Information Processing Variables in Hypothetically Psychosis-Prone College Students

Description: Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons… more

Biopsychosocial Factors Related to Health among Older Women

Description: Older adults are more vulnerable to the ill effects of life stress due to physiological changes associated with aging that result in decreased immunocompetence. Stressors interacting with an aging immune system may produce further declines in health. Variables shown to modulate the effect of stressors on neuroendocrine and immune function and health include social support, personality, coping style, and health locus of control. A comprehensive model is proposed that includes: life stressors, so… more

Characterization of Tolerance and Cross-tolerance between Noncompetitive N-methyl-D-aspartate (NMDA) Antagonists in Rats Trained to Self-administer Ketamine

Description: Ketamine and phencyclidine (PCP) are noncompetitive antagonists of the N-methyl-D-aspartate (NMDA) type of ligand-gated glutamate receptors. Both agents have high abuse liability, and may produce dependence. Tolerance to the reinforcing effects of drugs of abuse is widely regarded as a key component of the dependence process. Therefore, the present study was conducted to examine whether tolerance develops to the reinforcing effects of ketamine, and whether PCP and dizocilpine, a noncompetitive … more

Correlates and Predictors of Medication Noncompliance in Patients with Schizophrenia

Description: The treatment of schizophrenia today consists of a multi-component system of services. Mental health professionals generally agree that anti-psychotic medications are an essential treatment for schizophrenia. However, adherence to medication regimens by patients with schizophrenia is notoriously poor. To identify correlates and predictors of medication compliance, the Schedule for Affective Disorders and Schizophrenia (SADS), a semi-structured diagnostic interview, was administered to 90 outpat… more

Cultural Differences in Pain Experience and Behavior among Mexican, Mexican American and Anglo American Headache Pain Sufferers

Description: Review of previous research on cultural differences in pain experience and/or pain behavior revealed that cultural affiliation affects pain perception and response. Unfortunately, the many inconsistent findings in the literature on cultural differences in pain experience and behavior have made interpretations and comparisons of results problematic. These inconsistent findings could be attributed to variations in acculturation level among cultural groups. The purpose of this study was to investi… more

The Effects of Mirror Confrontation on Body Image Ratings

Description: There are conflicting data in the literature regarding the effects of mirror exposure on subjective body-image evaluation. Much of the objective self-awareness research by Duval and Wicklund concluded that the presence of a mirror leads people to evaluate themselves negatively, while other studies have reported contrary findings. The primary purpose of this study was to determine the effects of mirror confrontation on individuals' body image ratings. Subjects were 88 childless, female universit… more

The Role of Anger/Hostility on Physiological and Behavioral Risk Factors for Coronary Heart Disease

Description: The purpose of this study was to examine the role of anger/hostility on physiological and behavioral coronary heart disease risk factors. It was hypothesized that anger/hostility would contribute to the severity of CHD via consummatory behaviors such as smoking, poor diet, and excessive alcohol consumption. Some researchers suggest that negative consummatory behaviors play a direct causal role in CHD. The present study proposed that hostility predisposes an individual to these behaviors, and th… more

The Role of Neuronal Histamine in Memory Processing

Description: Neuronal histamine(HA) may play a role in memory processing. This hypothesis is based upon evidence that the action of histamine at central H1 and H2 histamine receptor sites has been shown to modulate memory of rats and mice in adversely-motivated tasks. The purpose of this study was to test this hypothesis more thoroughly in mice using two distinct approaches to neuronal HA manipulation. One approach involved the use of new pharmacological agents which act at the histamine H3 receptor. It has… more
