Drawings by Individuals With Williams Syndrome: Are People Different From Shapes?

Abstract

Because it is unclear whether people with Williams syndrome produce drawings that are delayed or deviant, we examined these two possibilities in Draw a Person and figure copying tasks (VMI) in 28 persons with Williams syndrome, 28 with mixed etiologies, and 28 with Down syndrome. All human figures could be classified into discrete stages of drawing development, and in all groups, drawing tasks were significantly correlated with MA. Human figures from participants with Williams syndrome were no more deviant than their counterparts, nor did they show "local-global" differences. Draw a Person scores exceeded VMI scores in the Williams syndrome group, whereas the Down syndrome group showed relative strengths on both drawing tasks, and the mixed group had no profile. Developmental and phenotypic implications of findings are discussed.
