Spatial location 1 Running head: SPATIAL LOCATION AND WILLIAMS SYNDROME Evidence for Unusual Spatial Location Coding in Williams Syndrome: An Explanation for the Local Bias in Visuo-Spatial Construction Tasks?

Individuals with Williams syndrome (WS) display poor visuo-spatial cognition relative to verbal abilities. Furthermore, whilst perceptual abilities are delayed, visuo-spatial construction abilities are comparatively even weaker, and are characterised by a local bias. We investigated whether this differentiation in visuospatial abilities can be explained by a deficit in coding spatial location i...

Texture segmentation and Williams syndrome 2 Abstract Williams syndrome (WS) is a developmental disorder in which visuo-spatial cognition is poor relative to verbal ability. At the level of visuo-spatial perception, individuals with WS can perceive both the local and global aspects of an image. However, the manner in which local elements are integrated into a global whole is atypical, with rela...

DRAWING STRATEGIES IN WILLIAMS SYNDROME 1 Running head: DRAWING STRATEGIES IN WILLIAMS SYNDROME Drawing the line: Drawing and construction strategies for simple and complex shapes in Williams syndrome and typical development

In the typical population, a series of drawing strategies have been outlined, that progressively emerge during childhood. Individuals with Williams syndrome (WS), a rare genetic disorder, produce drawings that lack cohesion, yet drawing strategies in this group have hitherto not been investigated. In this study WS and TD groups drew and constructed (from pre-drawn lines and shapes) a series of ...
