1. How does cognitive genetics explain the spatial cognitive deficits in WS?
- Genes missing in WS also involved in anatomical development of dorsal stream pathways
- WS individuals impaired in spatial cognition as dorsal stream develops unusually bc WS individual does not detect visuo-spatial properties

2. What does neuroconstructivism emphasise?
- The role of gene expression THROUGH developement. Early cognitive profile inferred from adult end state. Fractionation of strengths and weaknesses across domains,disregard of environment
- The role of genes in coding cognitive abilities. Are specific cognitive modules selectively affected?
3. What does the local-processing bias hypothesis suggest about the nature of WS visual-spatial disorder?
- WS have issues with the global form of objects but do not struggle with fine detail
- WS have issues with the local features of objects but do not struggle with global arrangement
4. What is the main premise of the dorsal stream deficit hypothesis?
- Structural abnormalities in dorsal stream of WS interact with intact ventral to contribute to visual-spatial deficits
- Structural abnormalities in dorsal stream of WS contribute to visual-spatial deficits
- Structural abnormalities in ventral stream of WS contribute to visual-spatial deficits
- Structural abnormalities in ventral and dorsal stream of WS contribute to visual-spatial deficits
5. How does cognitive genetics explain WS?
- The genes coding for language skills are intact, other developmental disorders are impaired on these genes.
- The adult state of the language system may be mature but not 'intact'. Language is atypical in many ways, WS informs about the low level processes of language
