Event-Related Potential Evidence For Multiple Causes Of The Revelation Effect, P. Andrew Leynes, Joshua Landau, Jessica Walker, Richard J. Addante Oct 2004

Event-Related Potential Evidence For Multiple Causes Of The Revelation Effect, P. Andrew Leynes, Joshua Landau, Jessica Walker, Richard J. Addante

Psychology Faculty Publications

Asking people to discover the identity of a recognition test probe immediately before making a recognition judgment increases the probability of an old judgment. To inform theories of this “revelation effect,” event-related potentials (ERPs) were recorded for revealed and intact test items across two experiments. In Experiment 1, we used a revelation effect paradigm where half of the test probes were presented as anagrams (i.e., a related task) and the other items were presented intact. The pattern of ERP results from this experiment suggested that revealing an item decreases initial familiarity levels and caused the revealed items to elicit similar …


Psychological Factors Associated With Anticipatory Nausea And Vomiting, Melinda L. Nielsen Sep 2004

Psychological Factors Associated With Anticipatory Nausea And Vomiting, Melinda L. Nielsen

Loma Linda University Electronic Theses, Dissertations & Projects

Many cancer patients experience adverse chemotherapy-related side effects. The present study examined the relationships among disease variables (i.e. stage of cancer, type of breast cancer), medical treatment variables (i.e. toxicity of chemotherapy regimen, strength of antiemetic treatment), psychological variables (i.e. health locus of control, anxiety sensitivity, desire for control, coping strategies), and anticipatory nausea and vomiting in women with breast cancer. One hundred women with breast cancer completed the Multidimensional Health Locus of Control Scale - Form C, the Anxiety Sensitivity Index, the Krantz Health Opinion Survey, the Coping Inventory for Stressful Situations, and the Morrow Assessment of Nausea and …


Pavlivian Conditioning To Insulin-Induced Hypoglycemia As Indicated By Glycemic Response Motor Activity And Anxiety, Jermaine Dionte Jones Jul 2004

Pavlivian Conditioning To Insulin-Induced Hypoglycemia As Indicated By Glycemic Response Motor Activity And Anxiety, Jermaine Dionte Jones

Psychology Theses & Dissertations

The purpose of this experiment was to demonstrate the responses to stimuli predicting the onset of hypoglycemia {HG), specifically the overt behavioral and glycemic conditioned responses to insulin-produced HG. When drug-opposite compensatory responses become associated with situational and environmental cues that predict drug administration, compensatory mechanisms can be elicited solely by drugassociated cues. Several studies have been conducted to determine the conditioned bloodglucose responses as elicited by stimuli predicting hypoglycemia. However, only a few studies have examined the behavioral conditioned responses associated with hypoglycemia. Insulin-induced HG and the elevated plus maze (EPM) procedure were utilized to determine the direction of …

Comparisons Among Parent Reports And Self-Reports Of Sleep In Adhd And Normal School-Aged Children, Diana M. Turner-Eadie Jan 2004

Comparisons Among Parent Reports And Self-Reports Of Sleep In Adhd And Normal School-Aged Children, Diana M. Turner-Eadie

Psychology Theses & Dissertations

The objective of the study was to investigate whether school-aged children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) experience greater sleep disturbance than do normally-developing children. Participants included 33 parents and their children with ADHD (mean age = 10.7 ± 1.7 years) and 33 parents and their children without ADHD (mean age = 10.7 ± 1.6 years). Both parents and their children completed sleep questionnaires developed to assess a number of sleep variables. Based on parental report, the Total Sleep Disturbance score was significantly greater for the ADHD group than for the comparison group. Parents indicated that children with ADHD had …

The Selfish Nature Of Generosity: Harassment And Food Sharing In Primates, Jeffrey R. Stevens Jan 2004

The Selfish Nature Of Generosity: Harassment And Food Sharing In Primates, Jeffrey R. Stevens

Jeffrey Stevens Publications

Animals may share food to gain immediate or delayed fitness benefits. Previous studies of sharing have concentrated on delayed benefits such as reciprocity, trade and punishment. This study tests an alternative model (the harassment or sharing–under–pressure hypothesis) in which a food owner immediately benefits because sharing avoids costly harassment from a beggar. I present an experiment that varies the potential ability of the beggar to harass, and of the owner to defend the food, to examine the effects of harassment on food sharing in two primate species: chimpanzees (Pan troglodytes) and squirrel monkeys (Saimiri boliviensis). For …


Effect Of Ondansetron And Delta(9)-Tetrahydrocannabinol On The Establishment Of Lithium-Induced Conditioned Taste Avoidance In The House Musk Shrew (Suncus Murinus), Magdalena Kwiatkowska Jan 2004

Effect Of Ondansetron And Delta(9)-Tetrahydrocannabinol On The Establishment Of Lithium-Induced Conditioned Taste Avoidance In The House Musk Shrew (Suncus Murinus), Magdalena Kwiatkowska

Theses and Dissertations (Comprehensive)

Recent evidence suggests that toxin-induced taste avoidance in the non-emetic rat is not mediated by conditioned sickness. In contrast, it appears that toxin-induced taste avoidance in an emetic species is mediated by conditioned sickness. The present experiments evaluated the potential of the anti-emetic agents, ondansetron [OND; a serotonin receptor (5-HT3) antagonist] and Delta(9)-tetrahydrocannabinol [THC; a cannabinoid (CB 1) agonist] to interfere with lithium chloride (LiCl)-induced taste avoidance in the house musk shrew (Suncus murinus). In Experiment 1, shrews were pretreated with OND (1.5 mg/kg) or saline 30 min prior to drinking 0.1% saccharin solution then they were injected with LiCl …
