Abstract
Perceptual grouping was studied psychophysically with spatially periodic visual patterns. Different two-dimensional arrangements of identical elements (squares, diamonds, or disks) were used as test stimuli. At an exposure duration of 33 ms, the perceived orientational structure was found to depend upon the orientations of the most visible spatial frequency components. If the fundamental frequency was high (5 cpd), the perceived orientations were independent of the shape of the elements. If the fundamental spatial frequency was low (.5 cpd), the shape of the elements determined the perceived orientational structure. The results also show some response bias which is discussed.
