Configural visual abilities in thirteen children with Williams syndrome (WS) compared to 13 children matched on mental age and 13 children matched on chronological age. Configural abilities were tested through four tasks (1) Silhouette (2) Fragmented (3) Mooney and (4) overlapping figures. In the first three tasks, it was necessary to take into…
