The relative contribution of featural versus configural face processing strategies in Williams syndrome
by Isaac, Linda, PhD, ALLIANT INTERNATIONAL UNIVERSITY, SAN DIEGO, 2007, 0 pages; 3280895
 

Abstract: A rare genetic disorder occurring in approximately one in 20,000 live births (Williams Syndrome Association, 2005), Williams Syndrome presents an uneven cognitive profile of spared face processing and language skills that contrasts with impairment in the cognitive domains of spatial cognition, problem-solving, and planning. To date, it remains unclear whether individuals with Williams Syndrome process faces using a local strategy that focuses on features or a global strategy that takes into consideration the contour of a face and spatial relations between features. Faces are extraordinarily rich sources of information and critical to our adaptation that at one glance can reveal a person's age, sex, mood, and familiarity of a person or not. To investigate the underlying processes disparity of these visuospatial deficits and limited face recognition ability, this study assessed face processing skills in Williams Syndrome using a design that included presentation of thatcherized and nonthatcherized faces, upright and inverted face orientation, and happy and neutral faces to assess their impact on face recognition. The sample consisted of eighteen participants with Williams Syndrome, ten participants with non-specific developmental delay and ten normal control participants. The study found that persons with Williams Syndrome process faces in a manner that is comparable to typically-developing individuals.
