Thesis (Ph.D.)--Boston University / The purpose of this experiment was to investigate the relationship between stimulus generalization ani the variables of stress and defense style. Accordingly, performance on an auditory stimulus generalization task under no stress and stress conditions was studied among a group of college students. Half of the group was composed of subjects who were classified as repressors while the other half consisted of subjects classified as intellectualizers. Predictions were generated from research related to a) the relationship between stress induced by a noxious stimulus and performance on stimulus generalization tasks and b) the effectiveness of defense styles in the management of anxiety aroused by a stressful situation.

Despite a prevailing paradigm that emphasizes an interaction of vulnerability and stress to account for the etiology of schizophrenia, diathesis—stress models of subsequent course and outcome of this disorder are rare. Even the simpler stress— process model, where the influence of stressors is mediated by supportive social relationships, has received little attention in studies of the course of schizophrenia. The objective of this study was to assess the following components of a diathesis—stress model as they predict the five-year outcome of first-episode schizophrenia: (1) stressful life events; (2) supportive social relationships; (3) brain lateral ventricle size; and (4) smooth pursuit eye movements. As part of the Greater Vancouver M.A.P. Project, we recruited first-episode DSM-III schizophrenia and affective psychosis patients. At intake to the study, their social relationships, smooth pursuit eye movement function, and brain ventricle size were assessed. Life events in the previous year were measured at intake; events over the following 18 months were assessed in two later interviews. Five years later we assessed outcome, using a global rating of social and occupational functioning. Descriptive results showed substantial variability within the schizophrenia group at intake and outcome. The trajectory of adaptive functioning over time was remarkably similar for the schizophrenic and affective psychosis groups. Of the four hypothesized predictors, only social relationships were associated (p=.O3) with five—year outcome. The number of life events was not associated with five—year outcome, nor was either of the biological risk factors. As a result, the predictor variables could not be combined in either a stress—process model or a vulnerability—stress model of the course of schizophrenia. That social relationship variables are associated with five-year outcome supports earlier findings regarding 18-month outcome, including the differing predictive roles for family and nonfamily relationships. The absence of hypothesized results for the life events data probably indicates that too much time had passed between outcome and the events as measured. Finally, that brain ventricle size and eye-movement dysfunction predict 18-month but not five—year outcome may indicate that impairment due to biological factors is expressed only in the early stages of schizophrenia. / Arts, Faculty of / Psychology, Department of / Graduate

In today’s industry, many occupations require manpower resources to include both labor and cognitive resources. As the technology is rapidly changing and businesses are becoming more dependent on cognitive performance, it is essential to find any effect physical stress might have on task performance. Situational awareness is also becoming an integral part of human task performance. It is critical for many operations to design systems such that the effects of physical stress, however minute, on task performance and situational awareness are considered. The test methodology developed here measures the effect of stress on cognitive task performance as a result of situational awareness related to the task. The test measured and compared task capacity among different age groups and different working groups. A comparison was made on task performance based on the effects of low level physical stress and lack of it. Response time and accuracy were measured for statistical analysis. The subject’s stress levels were measured before starting the test to create a baseline for the candidates stress level. The developed tool was able to detect the effect of stress on task performance successfully and efficiently. Subjects with previous work experience performed better both in Phase I and Phase II of the experiment as compared to subjects with no previous work experience. The analysis indicates low level stress does have significant effects on task performance. In reality, stress is an unavoidable factor in daily activities. When designing any system that requires cognitive tasks, stress needs to be considered as a contributing factor to the variability of operation.

This research is concerned with the differential ability of individuals to cope with stressful situations. It began with an effort to determine how a particualr individuals outlook on life rendered him more or less able to cope with stress. Therefore, literature relating belief systems to personality factors was surveyed, in hope of gaining some insight into the important determinants of adaptive as opposed to maladaptive belief systems.
