We examined the longitudinal transition on copying and drawing of a patient with unilateral neglect who had lesion in the right hemisphere. The findings were as follows. Firstly, the copying of cube perspective figure in the patient developed from the two dimensional squares overlapped each side of a cube to the three dimensional figure missed left side of the cube. This process of the cube copying revealed the growth of perceptual representation in the brain. Secondly, the patient drew only the right side of flower in the fourth copying (323 days after lesion), but he drew the left side of leaves in the second and third copying (82 and 102 days). In these copying, he drew interestingly half of the leaf on the left. This finding suggested that it was appropriate to consider unilateral spatial neglect at the object-centered coordinate frame than the viewer-centered coordinate frame. Thirdly, thinking activity participates deeply in drawing, therefore, drawing is more highly flexible than copying. Longitudinal observations on copying and drawing of the case suggested that copying was appropriate for evaluation of unilateral spatial neglect than drawing.
