An Exploratory Study Of Varying Phenotypes Of Posttraumatic Stress Among A Comorbid Substance Misuse Population, Dennis Allen Donahue
Doctoral Dissertations
Objective: The purpose of this study was to explore differences in presentation of posttraumatic distress (PTD) that may represent different phenotypes, such as a possible cognitively-driven variant, in addition to those rooted in the prevailing conditioned-fear model. In conjunction, links to substance misuse and a purposeful selection bias for specific drugs-of-choice (DoC) based on phenotype variation were examined. Method: A convenience sample of inpatients in residential treatment for substance misuse who also endorsed posttraumatic distress following at least one previous traumatic experience (N = 177) completed self-report assessments and an in-person direct inquiry. Results: Hierarchical cluster analysis and ANOVA …

The Impact Of Psychological Reactance And Desire For Control On Perceptions Of Common Elements Of Cognitive, Affective, And Behavioral *Change, Morgan Edward Williams
Doctoral Dissertations
The present study was designed to assess the impact of two dispositional variables, psychological reactance and desire for control, on individual perceptions of common elements of psychological change. These common elements represent cognitive, affective, and behavioral aspects of psychological change. The study tested whether individuals with different levels of psychological reactance and desire for control systematically differed in their perception of the importance of elements relevant to psychological change. Participants (N = 420) completed three self-report assessment instruments: (a) the Common Elements of Change Questionnaire, (b) Hong's Psychological Reactance Scale, and (c) the Desirability of Control Scale. As hypothesized, …

The Use Of Prior Knowledge In Learning From Examples, Stephen B. Blessing '89
Doctoral Dissertations
This dissertation examines the way people acquire procedures from examples, and provides a computational model of the results. In four experiments, people learned an analog of algebra. For each experiment, the initial know ledge that people had of the task was varied. In two experiments (Experiments 1 and 3), the syntactic know ledge that people had concerning the task w as manipulated. The knowledge of syntax that participants had, particularly the ability to correctly parse the character string, was found to be a major determiner in the way participants acquired the rules. Experiment 2 explicitly manipulated participant's awareness as to …
