BL: Yes, things that come from that, anyway. Things like differences in
 vision. Roughly twenty percent of women are tetra-chromatic, which means
 their ability to perceive color is much higher than anyone else's. There
 are differences in cognitive ability also that have to do with when and
 how much androgen exposure there is to the brain of a developing child,
 etc. There are other physiological differences that are just the artifacts
 of development, because so much of our visual system is soft-wired until
 adolescence..

 klinikal syndrome[s] : visual agnosia
 ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
 –apperceptive [difficulty "seeing" objects] 

 =fundamental difficulty in forming a percept 
  [mental impression of something perceived by 
  senses]; elementary visual information is 
  processed, but it can't be bound together so 
  that a meaningful whole is perceived.

 –associative [difficulty "knowing" what an 
  object is]

 =basic information can be integrated to form 
  a meaningful perceptual whole, but the per-
  ceptual whole cannot be linked to stored 
  knowledge.
