Abstract
The influence of spatial and temporal frequency on possible meridional variations in spatial displacement detection were examined. The results indicate that a spatial displacement detection oblique effect occurs at high spatial frequencies and low temporal frequencies. This anisotropy is not due to differences in perceived contrast along the vertical and oblique axes, since the orientations were equated for perceived contrast in each of the stimulus conditions. The spatialdisplacement oblique effect is similar to both the contrast sensitivity and perceived contrast oblique effects in its dependence on the spatial and temporal properties of a stimulus. These different oblique effects are discussed in terms of a possible common neural basis.
