چکیده انگلیسی
This study examined spatial-frequency effects on a motion-pooling process in which spatially distributed local one-dimensional motion signals are integrated into the perception of global two-dimensional motion. Motion pooling over two- to three-octave frequency differences was found to be nearly impossible when all Gabor elements had circular envelopes, but possible when the width of high-frequency elements was reduced, and the stimulus as a whole formed a closed contour configuration. These results are consistent with a view that motion pooling is controlled by form information, and that spatial-frequency difference is one, but not an absolute, form cue of segmentation.
