Previous research suggests individuals with autism may be less influenced by a three-dimensional interpretation when copying line drawings (Sheppard et al. "J Autism Dev Disord" 37:1913-1924, 2007). The current research aimed to determine whether this reduced dimensionality effect extends to drawings of an actual object. Twenty-four children and…

Mottron and colleagues found that individuals with autism were less affected by geometric impossibility than comparison participants on a copying task. The current experiment sought to determine whether a local perceptual style could account for this. Participants with and without autism copied possible and impossible geometric figures. Geometric…

Studies of intellectual realism have shown that children aged 7 to 9 copy a line drawing of a cube less accurately than a non-object pattern composed of the same lines (Phillips, Hobbs, & Pratt, 1978). However, it remains unclear whether performance is worse on the cube because it is a three-dimensional representation, or because it is a…
