The present research is a field investigation of trauma and its cognitive and emotional consequences. One hundred and nineteen sex trade workers were interviewed about sexually traumatic experiences. The primary focus of this research was an examination of the quantity and quality of memory for sexual trauma. Various predisposing, precipitating, and perpetuating factors were examined regarding their influence on memory and posttraumatic stress. One objective of this study was to test certain assumptions of the biopsychosocial model of eyewitness memory (Hervé, Cooper, & Yuille, 2007), which proposes that individuals differ along a continuum of arousal sensitivity and predicts the quantity and quality of recall. Up to three types of memory narratives were elicited from each participant: (a) one positive event (b) one well-remembered sexual assault, and (c) one sexual assault for which the participant had poor recollection. Each memory was assessed for peritraumatic and posttraumatic factors. The participants also filled out a number of individual differences measures. The results indicated that the participants had extensive histories of trauma, many of which began in their childhood. It was shown that well-remembered sexual assaults contained more narrative details than memories of positive events and less-well-remembered sexual assaults. Such variability of memory for sexual violence is in line with Hervé et al.'s model as well as other field studies of traumatic memory. This was the first study to demonstrate such variability within-subjects. Various moderating factors of memory were examined, for example, dissociation and different symptoms of posttraumatic stress. Some of the findings were at odds with traditional theories, laboratory findings, and certain assumptions held by many eyewitness memory experts regarding the relationship between stress and memory. A second objective of this dissertation was to examine predictors of post traumatic stress disorder. The findings largely confirmed the literature. Men and women did not differ in their levels of posttraumatic stress. Overall, the complexity of clinical symptoms in survivors of repeated sexual violence is highlighted. The results are discussed in terms of their implications for theory development, future research, the criminal justice system, and in terms of their relevance for treatment providers and assessors. / Arts, Faculty of / Psychology, Department of / Graduate

The objective of this research was to investigate relationship between dissociative and associative cognitive strategies for coping with the discomfort of running and running performance. Subjects were volunteers enrolled in two Dynamic Fitness classes which were taught during Spring Quarter, 1980, at Utah State University. Class A consisted of 36 subjects (24 male, 12 female) and Class B consisted of 28 subjects (13 male, 15 female). All pretest, posttest, and treatment procedures were conducted during the class's respective regularly scheduled meeting times. Subjects completed a 2.75 mile, timed, pretest run and were systematically assigned to one of three groups based on pretest time: 1) Control, 2) dissociation training group, and 3) association training group. Two training sessions were conducted to provide instruction in developing and using a cognitive strategy for both dissociation and association groups. Control group subjects also met with the researcher twice, but no instructions for development and use of a cognitive strategy were given. A posttest 2.75 mile, timed run was completed and subjects completed a posttest questionnaire. Due to differences in procedures for subject recruitment and weather conditions for the posttest run, data from Class A and B were analyzed separately. Analysis of covariance revealed no statistically significant relationship between teaching of a cognitive strategy and running time for either class. Posttest questionnaire information was also analyzed. For both classes, statistically significant negative correlations were found between difference for pretest/posttest timed runs and dissociation points as reported on the posttest questionnaire. Also t-tests of independent means showed that association group subjects reported significantly higher levels of association than control group subject for both classes. It was suggested that although training may have increased the reported use of a cognitive strategy it was not an important factor in running performance. The researcher suggested, instead, that willingness to exert oneself may have been the primary factor in determining performance in relationship to physical limitations.

Sleep disturbances have been observed across the entire psychosis spectrum. Research has begun to focus on the clinical high risk (CHR) period for psychosis, as the presence of sleep disturbance can be examined separately from the effects of antipsychotic medication and is potentially a risk factor for later psychosis. Several studies have demonstrated a link between sleep disturbance and worsened positive symptoms in CHR individuals. However, sleep disturbance is not unique to the psychosis-spectrum and is well documented in individuals experiencing dissociation. Transdiagnostically, dissociation has been associated with poorer outcomes and reduced treatment response. Despite the established associations between these variables, their respective contributions to positive symptom severity in the CHR period has not yet been characterized. This study examined the separate and combined contributions of sleep quality and dissociation on positive symptom severity in a cross-sectional sample of individuals identified as being at CHR for psychosis. Hierarchical linear regression was conducted to examine the independent and additive influence of sleep quality and dissociation on unusual thought content, suspiciousness, and perceptual abnormalities. Finally, logistic regression was used to determine if sleep quality and dissociation increase odds of a CHR diagnosis. Analyses of indirect effects revealed a significant indirect effect of sleep disturbance on perceptual abnormalities through dissociation in the CHR group. In addition, both sleep disturbance and dissociation significantly contributed to a model predicting to perceptual abnormalities, also in the CHR group. In the total sample, both sleep quality and dissociation significantly increased the odds of a CHR diagnosis. These results suggest that dissociation plays a significant role in the sleep-attenuated positive psychotic symptom relationship in the CHR period, and as a result, could be a modifiable treatment target in these individuals. / Psychology

There is a paucity of research on the diagnosis of dissociative disorders in children. Most children are misdiagnosed with more common mental disorders with similar symptoms. Earlier recognition of dissociative disorders can save years of pain, suffering, and cost. This qualitative collective case study examined the process of diagnosing dissociation in two children under the ages of 12 at the beginning of treatment. A concurrent focus on the training and development of the therapist/researcher is included. Archival data including progress notes, psychotherapy notes, assessments, correspondence, legal documents, school records, and medical records were analyzed using within-case and cross-case analyses to identify individual and common themes that may expedite the diagnosis of dissociative disorders in children. The narrative presentation of a qualitative study with its thick, rich description may increase the understanding of clinicians with little or no experience and help them to differentiate these disorders from other disorders with overlapping symptoms. Factors that impeded and advanced the recognition of dissociative disorders were identified. Clinical findings underscore the role of knowledge and training, experience, and consultation in the diagnosis of dissociative disorders.

L'interaction de la radiation ionisante avec la matière biologique implique la formation d'une très grande quantité d'électrons de basse énergie, pour la plupart en deçà de 20 eV, qui déposeront ultimement la plus grande partie de l'énergie transportée par cette radiation. Il est connu que ces électrons peuvent causer des dommages très importants à l'acide désoxyribonucléique (ADN) d'une cellule. Cependant, la connaissance des mécanismes par lesquels ces dommages sont créés demeure incomplète. Nous avons étudié l'effet des électrons de basse énergie (i.e., 1 - 18.5 eV) sur des films minces d'un analogue au désoxyribose de l'ADN, soit le tétrahydrofurane (THF), condensés sur un séparateur inerte de krypton. Nous avons observé à l'aide de spectres d'excitations vibrationnelle et électronique que l'exposition à ces électrons pouvait impliquer l'ouverture du cycle de la molécule de THF résultant en la formation d'un composé de type aldéhyde, identifié avec le plus de certitude comme étant du butyraldéhyde.

The object of this thesis is to consider the conceptions of Dissociation and Repression with a view to determining in what way, if any, the processes are related to one another. These two conceptions have played a part of unrivalled importance in modern psycho-pathology, but no satisfactory attempt seams to have bean made to determine the exact nature of their relationship to one another. The conclusions reached in this thesis regarding their relationship constitute, so far as the writer is aware, an original contribution to the subject.
