Post-Exposural Eye Movements and Lateral Differences in Tachistoscopic Recognition

摘要: Left-right differences in visual field accuracy obtained studies of tachistoscopic recognition have been typically discussed terms a covert post exposure scanning process derived from the horizontal eye movements (EM) habitually used reading. Further, some evidence exists that indicates occurrence EM concomitant with process. By monitoring during representative task, present study attempted to establish relation between overt elicited by and response accuracy. Using projection tachistoscope (duration 100 msec.), 8 female Ss were presented random trial series 8-element letter, number, symbol arrays exposed bilaterally, 4 letter unilaterally. In second series, bilateral unilateral at 1 sec. duration. A high resolution corneal reflection technique was detect latency direction EM. The pattern for alphanumeric stimuli generally conformed results previous investigations based on grouped data. Marked individual variation noted results, suggesting source variability worthy analysis. Response highly variable demonstrated lack lateral disparity, indicating an iii unstructured encoding this material. established as reliable phenomenon, identical topography evoked stimulus present. However, behaviour did not relate accuracy, result does limit use reading model Rather, indicate are involved Further implications theory future research detail.
