Visual Encoding of Spatial Relations.
Abstract
Psychophysical studies of the processes underlying spatial localization and their relationship to both lower and higher level processing were conducted. The spatial extent of position integration areas was measured and found to be adequate to account for the increase in separation discrimination thresholds with separation. The influence of the spatial frequency of embedded targets was investigated and found to be insignificant, as it had previously been found to be for isolated targets. The relationship between separation discrimination and object formation was investigated and a model of the process of object formation developed. Studies on how area is encoded were conducted and related to the model of object formation.... Human vision, Visual psychophysics, Visual spatial localization, Position
