Eeg Coherence And Amplitude Effects Of Rhythmic Auditory And Visual Stimulation With An Emphasis In Computational Methods, Jon Alan Frederick

Doctoral Dissertations

The photic driving response, the effect of a flashing light stimulus on the cortical EEG, has proven to be a sensistive neurometric that varies with differences in perception, mood, and physiological states. The diverse effects of photic stimulation have made commercially available "brainwave syncronizers" popular among consumers and even among some clinicians. It is common in the design of these devices to combine a rhythmic auditory stimulus with the visual stimulus. However, little if any experimental evidence supports the assumption that auditory stimulation enhances the photic driving effect. Therefore, this study compared the amplitude and coherence effects of three stimulation …

Living In Prison: Evaluating The Deprivation And Importation Models Of Inmate Adaptation, Lisa Danielle Velarde

Doctoral Dissertations

The purpose of the present study is to broaden knowledge in the area of adjustment to incarceration. Clemmer (1950) proposed that a process known as prisonization develops as inmates adjust to the arduous circumstance of incarceration. Previous research has compared two competing models of adaptation, known as importation and deprivation, as predictors of prisonization. Given that Clemmer (1950) originally hypothesized that prisonization serves as a method of adjusting to the prison environment, the present study explored the relationships among the importation model, the deprivation model, prisonization, and adjustment. In an attempt to take into consideration both person and environmental factors, …

Response Expectancy And Experimenter Bias As Factors Affecting Hypnotic Responsiveness, K. Shannon Wilson

Doctoral Dissertations

This study examined the effect of subjects' expectations regarding their hypnotizability, and the effect of experimenter bias, on subsequent levels of hypnotic responsiveness. Ninety undergraduate psychology students, none of whom had previously been hypnotized, participated in the study. Subjects were divided into four groups (two groups of 30 and two groups of 15), in a two by two design. The two experimental groups received a manipulation (subtle alterations of lighting conditions in the experimental room in order to confirm suggestions given under hypnosis) designed to increase their level of expectations regarding their hypnotic performance. Their actual hypnotic responsiveness was then …

Organizational Citizenship Behavior As A Predictor Of Work Team Performance, Tjai M. Nielsen

Doctoral Dissertations

This study assesses the relationships among organizational citizenship behavior (OCB), task interdependence, and performance at the team level. A longitudinal, correlational field study was conducted with 52 work teams from 6 organizations located in the Eastern United States. At the individual level of analysis it was hypothesized that OCB is positively related to individual performance. At the team level of analysis it was hypothesized that OCB is positively related to concurrent team performance, subsequent team performance, and customer-rated performance. It was also predicted that customer-rated OCB is related to concurrent and subsequent team performance. Task interdependence was expected to moderate …

An Investigation Of The Relationship Between The Family Of Origin And Selected Career Development Outcomes, Timothy Dean Dodge

Doctoral Dissertations

The present study was designed to examine, from the perspective of Bowen family systems theory (Papero, 1990) and Williamson's theory of personal authority in the family system (Williamson, 1981, 1982a, 1982b), the impact of family dynamics on the career development of college students and to overcome methodological weaknesses of prior research in this area. Methodologically, the present study overcomes weaknesses of prior research by providing a unifying theory from which measures of family dynamics are derived and by measuring career outcomes which are logically tied to family dynamics. Career outcome measures selected for the study include vocational identity, career decision-making …

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, …

Confirmatory Factor Analysis Of The Coping Style Inventory In A College Sample, Christopher Garth Bellah

Doctoral Dissertations

The present study conducted a confirmatory factor analysis of the Coping Style Inventory (CSI). A comprehensive review of the history of stress and coping research was provided, along with a presentation of suggestions for future research that have indicated a need for a melding of both theory-driven and empirically-driven methodology in coping assessment. Pursuant to this need, a pilot study was conducted to explore the factor structure and psychometric properties of the CSI (N = 560). Results of pilot work using a principle components extraction and a parallel analysis criterion for factor retention indicated that six primary factors were …

Postural Balance And Acceleration Threshold Detection For Anterior Horizontal Translation In Diabetic And Non-Diabetic Elderly, Venkatesh Balasubramanian

Doctoral Dissertations

Slips and falls, and even the fear of failing, can represent a major medical and functional deterrent to living independently, especially among the elderly population. Various groups of elders are at known risk for falling including, but not limited to, those with vestibular dysfunction, those with low visual acuity including visual neuropathies, and those with peripheral neuropathies. The first two groups are fairly well studied, but the relationship between the level of peripheral neuropathy and extent of falling has received relatively less attention.

In this study, using sliding linear investigative platform for analyzing lower limb stability (SLIP-FALLS), the psychophysical thresholds …
