Most individuals with WS (WSs) are intensely hypersensitive and severely impaired in the areas of perceptual and motor performance. This is apparent in the difficulties they usually face in performing everyday activities that involve visuospatial, motor, and visuomotor skills. Hypersensitivity to certain ordinary sounds plague almost all WSs, and tactile sensitivity affects quite a few. In addition, paradoxical perceptual abilities are often exhibited by WSs within the visual, auditory, and tactile areas of perception.
This chapter deals with the many difficulties and isolated skills of WSs in the areas of visuospatial, motor, and visuomotor integration, tactile sensitivity, and auditory sensitivity. Each area has its own distinct properties, its own specialized forms of clinical treatment, and psycho-educational techniques of intervention.
Most WSs are plagued with significant developmental delays and problems in performing many activities of daily life (Udwin & Yule, 1998a). Awkwardness, embarrassment, and even failure may beset their attempts to deal with certain aspects of self-care, using household appliances, participating in sports activities, or differentiating right from left. These are examples of areas of likely deficiency and frustration.
According to parents, 97% of children with WS (WSc) are impaired in drawing, 89% in cutting with a knife, 77% with personal grooming, and 77% in
