The strategy used in drawing a complex geometric design was compared in right-brain-damaged (RBD) and left-brain-damaged (LBD) stroke patients and normals. A record of the sequence of line segments used to copy the design was obtained. Normals drew elements of the figure as one unit, while LBD patients broke these elements into more than one unit. The unusual sequencing and fragmented, piecemeal approach of the LBD group was sometimes associated with a delay in attention to the right side, but did not necessarily lead to an impaired finished copy. As expected, the RBD distortions were more severe. It is concluded that an intact right hemisphere does not ensure a holistic approach to copying complex geometric figures.
研究比较了右脑损伤（RBD）和左脑损伤（LBD）的中风患者以及正常人绘制复杂几何图案时所采用的策略。记录了用于复制图案的线段顺序。正常人将图案元素作为一个整体绘制，而LBD患者则将这些元素分解为多个单元。LBD组不寻常的顺序和碎片化、逐块的方法有时与对右侧注意力的延迟有关，但不一定导致最终复制受损。正如预期的那样，RBD患者的变形更为严重。研究得出结论，完整的右脑并不能确保以整体方式复制复杂的几何图形。
