Temporal and spatial integration in dynamic random-dot stimuli.
Random-dot cinematograms comprising many different, spatially intermingled local motion vectors can produce a percept of global coherent motion in a single direction. Thresholds for discriminating the direction of global motion were measured under various conditions. Discrimination thresholds increased with the width of the distribution of directions in the cinematogram. Thresholds decreased as...
متن کاملSegregation from direction differences in dynamic random-dot stimuli
Previous research has shown that a field of random dots in which each dot alternates between a slow and a fast speed, can give rise to the percept of two superimposed sheets of moving dots when the alternations are out of phase or asynchronous with each other [Vis. Res. 35 (1995) 1691]. Under those conditions, observers can discriminate changes in the slow speed independent of changes in the fa...
متن کاملNulling the motion aftereffect with dynamic random-dot stimuli: limitations and implications.
We used biased random-dot dynamic test stimuli to measure the strength of the motion aftereffect (MAE) to evaluate the usefulness of this technique as a measure of motion adaptation strength. The stimuli consisted of noise dots whose individual directions were random and of signal dots moving in a unique direction. All dots moved at the same speed. For each condition, the nulling percentage (pe...
متن کاملHierarchical integration of individual motions in locally paired-dot stimuli
Recent psychophysical studies suggest that there are two types of motion integration processes in human visual system, i.e., the local and the global integration process. The existence of the local integration process is suggested by the vector-average perception in locally paired-dot (LPD) stimuli. Here, we investigated the relationship between the two motion integration processes by measuring...
متن کاملAn automated system for determining psychophysical stereo-threshold to dynamic random dot stimuli
We describe an approach to the problem of measuring stereoscopic thresholds to images of random dot stereograms. This involves using an Apple Macintosh computer with 640x480-pixel monitor with shutter glasses alternating the view to left and right eyes, while simultaneously changing the horizontal disparity of a pair of images on the screen so that it has ‘depth’. While this approach is not new...
