Post-Exposural Eye Movements And Lateral Differences In Tachistoscopic Recognition, R. Cameron Mcrae
Post-Exposural Eye Movements And Lateral Differences In Tachistoscopic Recognition, R. Cameron Mcrae
Theses and Dissertations (Comprehensive)
Left-right differences in visual field accuracy obtained in studies of tachistoscopic recognition have been typically discussed in terms of a covert post exposure scanning process derived from the horizontal eye movements (EM) habitually used in reading. Further, some evidence exists that indicates the occurrence of EM concomitant with the recognition process. By monitoring EM during a representative recognition task, the present study attempted to establish the relation between overt EM elicited by the task, and response accuracy. Using a projection tachistoscope (duration 100 msec.), 8 female Ss were presented with a random trial series of 8-element letter, number, and symbol …
An Investigation Of Some Electrophysiological Concomitants Of Hallucinations, Ronald S. Golemba
An Investigation Of Some Electrophysiological Concomitants Of Hallucinations, Ronald S. Golemba
Theses and Dissertations (Comprehensive)
The present research was designed to determine if a single LSD experience produces a detectable change in the electrical potential of the brain, and if so, how long that change lasts, and to examine the changes in the electrical potential of the brain associated with chemogenic and hypnogenic hallucinations. Four studies were conducted measuring the electrical potential between the front and back of the head in monkeys and humans. The frontal potential was shown to shift negatively with the use of LSD-type psychedelics but not with marijuana compounds. LSD caused the potential in humans to shift into the range commonly …
An Investigation Of Three Aspects Of Cognitive Style In Young Children, Briar D. Gaudun
An Investigation Of Three Aspects Of Cognitive Style In Young Children, Briar D. Gaudun
Theses and Dissertations (Comprehensive)
The purpose of the present study was to investigate the developmental concept of the process of differentiation as reflected in cognitive style with three and seven year old male and female Ss. The ideas underlying this study stemmed from the Witkin concept of an analytical versus a global cognitive style. The design, however, differed considerably from the studies of Witkin, Dyk, Faterson, Goodenough, and Karp (1962) by incorporating three aspects of psychological functioning which theoretically should be highly related, although they have never been investigated simultaneously. The three aspects of psychological functioning were perceptual articulation as measured by the Preschool …
