Williams syndrome is a genetic deficit caused by a micro-deletion on chromosome 7. Individuals with this syndrome exhibit an unusual cognitive profile which has captured the attention and imagination of cognitive scientists, neuroscientists, and developmentalists. This profile includes severely impaired spatial cognition together with relatively spared language. Understanding this intriguing cognitive profile is likely to be a complex undertaking, in part because each cognitive domain (space, language) is inherently complex and multi-faceted. In order to address this challenge, I suggest a strategy of "divide and conquer", in which we examine the spatial cognitive impairment by looking at different sub-domains which have already been established by studies of normal and brain-damaged adults.
