The influences of visibility and anomalous integration processes on the perception of global spatial form versus motion in human amblyopia
Do amblyopes demonstrate general irregularities in processes of global image integration? Or are these anomalies stimulus specific? To address these questions we employed directly analogous global-orientation and global-motion stimuli using a method that allows us to factor out any influence of the low-level visibility loss [Simmers, A. J., Ledgeway, T., Hess, R. F., & McGraw, P. V. (2003). Def...
متن کاملInteraction of spatial and temporal integration in global form processing
The mechanisms by which global structure is extracted from local orientation information are not well understood. Sensitivity to global structure can be investigated using coherence thresholds for detection of global forms of varying complexity, such as parallel and concentric arrays of oriented line elements. In this study, we investigated temporal integration in the detection of these forms a...
متن کاملBiological model of motion integration and segmentation based on form cues
Active vision is an essential part of every biological organism possessing an eye system: posture, eye movements, visual research, . . . All require a motion percept to operate. At the basis of active vision lays the ability to calculate movements of objects in the scene, at least on a su cient level to react correctly. In this report we present a model of motion integration and segmentation in...
متن کاملThe effects of age on the spatial and temporal integration of global motion
The purpose of this study was to determine the relative contributions of local element speed and/or spatial displacement to age-related deficits in global motion processing. Motion coherence thresholds (79% correct) were measured for discriminating the direction of translational random dot kinematograms (RDKs) as a function of dot speed and spatial displacement across the adult lifespan (20-79 ...
