摘要：
We measured the perceived spatial orientation of the low contrast regions of contrast modulated sine gratings. Subjects make systematic errors which depend upon the carrier spatial frequency acid the angle between the carrier grating and the modulation. The results for the spatial orientation task are compared with a motion domain analogue. The difference in the pattern of results for these two tasks suggests there exist separate strategies for encoding orientation in two-dimensional space and space-time.
