Document Summary

Specific language impairment: (sli) developmental disorder that specifically affects language, without any other disorder that can explain it (hearing, general cognitive development, etc. ) Not as much info available as williams syndrome. How is sli diagnosed: by definition, sli is a deficit in language development without any other accompanying cognitive or sensory deficits that could explain it. Furthermore, in cases where only one member of identical twins has sli, the other tends to show some language impairment, though perhaps not severe enough to meet the diagnostic criteria for sli. Ke family: family from london, exhibits particularly severe form of sli, particularly interesting is that the deficit has appeared in nearly half of the family members across at least three generation. Williams syndrome and specific language impairment form a double dissociation between intelligence and language ability. This suggests that language ability is independent of general intelligence. Williams syndrome: affects general intelligence, has no (or few) effects on language.
