This chapter discusses other reported deficits in processing visual location and orientation information. It highlights a recently reported case, involving a patient named PR, that bears a striking resemblance to that of AH. Both AH and PR were impaired in location and orientation perception, both made systematic left-right reflection errors, and both showed the same dramatic effects of exposure duration, motion, flicker, and eccentricity. The commonalities between the two cases strongly suggest that the underlying deficits are very similar and provide a basis for increased confidence in conclusions about the normal visual system drawn from AH's (or PR's) performance.

Keywords: visual perception; visual location; orientation perception; motion; flicker; eccentricity
