 							The Nature of the Deficit: Initial Conclusions

Show Summary Details


This chapter consolidates the conclusions from the preceding chapters and extends these conclusions on the basis of additional arguments and evidence. It contends that AH suffers from a selective developmental deficit in visual location and orientation perception. This deficit, which probably originated prior to AH's birth or in the early years of her life, affects high-level vision and causes distinctive location and orientation errors in a wide range of visual tasks. The deficit may also affect AH's ability to acquire knowledge in circumstances where processing of visual location and/or orientation information is implicated in the learning process (e.g., learning to spell).

Keywords: visual perception; selective visual deficit; visual location; orientation perception; learning to spell
