Document Summary
Drawing ability develops in a predictable sequence: closed geometric shapes open 3d shapes segmented human figures complete human figures. Drawing tasks are sensitive to many kinds of deficits and are easy and quick to administer. These tests are sensitive to perceptual, practic, and certain types of cognitive and motor impairment. In drawings, hemispheral inattention tends to be reflected in the omission of details, or even the entire array of info, on the side opposite of the lesion. Free drawings (drawing to command) tend to elicit evidence of inattention more readily than does copying from a model. Unilateral lesion patients sometimes position their drawings on the same side of the page as their lesions, thus underutilizing the side of space that is most susceptible to inattention. Most common pattern is the omission or disproportionate distortion of left- sided info in the drawings of patients with right-hemisphere lesions.
