Document Summary
- r. m. bauer (1993) in heilman and valenstein (eds) - inability to identify facial features, but the inability to recognize familiar faces (i. e. , famous people, friends, relatives or, in some cases, one"s own face) results from damage to the fusiform face area located in the inferotemporal cortex. Inaccurate visually-guided reaching: e. g. , clumsiness and apraxic behaviours. Dorsal stream vulnerability : example: williams syndrome (specific deletion on chromosome 7), w. s. patients typically exhibit full-scale iq >50 < 90 relative sparing of expressive language, good visual object recognition (esp. faces) Friendly" personality traits: poor performance on most visuo-spatial andconstructional tasks. Dorsal-stream vulnerability" has also been found to characterize a number of other developmental disorders, including hemiplegia, autism, developmental dyslexia, and fragile x syndrome: visually-related disconnection syndromes . Shorter latency components reflect peripheral visual processes -- retina (erg), lgn, V1,v2 longer latency components reflect central" processes .
