Attributional Style as a Predictor of Academic Success for Students with Learning Disabilities and Attention Deficit Disorder in Postsecondary Education

Description: Thirty one students with learning disabilities (LD) and/or with Attention Deficit Hyperactivity Disorder (ADHD) completed a combined Academic Attributional Style and Coping with Academic Failures Questionnaire. The reformulated learned helplessness model (Abramson, Seligman, & Teasdale, 1978) predicted that students with negative attributional styles (i.e., internal-stable-global attributions) experienced motivational, cognitive, and emotional deficits.

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

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

Distorted Time Perception as an Underlying Factor of Psychosis Proneness and Dissociation

Description: Distortions in the perception of time historically have been associated with dissociation and psychosis in clinical populations. However, the relations among dissociation, psychosis, and time perception in sub-clinical populations have not been investigated. In the present study, college undergraduates scoring either normally or deviantly high on the Per-Mag were given a Dissociative Experiences Scale (DES) and a computerized time-estimation/production task. Participants scoring high on the Per… more

Effects of Experimental Psychological Stress on Human Physiological Functioning: Mediation by Affiliation

Description: This investigation sought to identify differences in the human psychophysiological stress response when mediated by affiliation, by assessing heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), electrodermal activity (EDA), serum Cortisol (SC) concentration, interleukin-2 (IL-2) concentration, and state anxiety among subjects who underwent an anagram solution task. Thirty male subjects from the University of North Texas were randomly assigned to one of two experiment… more

Memory Functions among Children Irradiated for Brain Tumor

Description: Children who have received radiation therapy for the treatment of brain tumors have been shown to experience neurocognitive deficits which appear to increase over time. The purpose of this study was to examine the memory functioning of 22 children irradiated for brain tumor and 22 healthy children of the same age who had not received irradiation. Subjects were administered a brief form of the WISC-III, to obtain an IQ, and the Wide Range Assessment of Memory and Learning (WRAML), to evaluate vi… 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
