Fig. 2

A: An example of a drawn figure separated into two halves （right and left） for determining CC-3. The CC between the left half and the 180°-rotated right half of the drawn figure was 0.46 （P＝0.013; n＝215, 112, t＝1.96）. B: The same drawn figure separated into two halves （upper and lower） for determining CC-4. The CC between the upper half and the 180°-rotated lower half of the drawn figure was 0.42 （P＝0.013; n＝108, 223, t＝1.96）. C: The same drawn figure separated into four quadrants for determining CC-5. The CC between the left upper and the 180°-rotated right lower quadrants of the drawn figure was 0.38. D: The same drawn figure separated into four quadrants for determining CC-6. The CC between the left lower and the 180°-rotated right upper quadrants of the drawn figure was 0.49 （P＝0.018; n＝107, 112, t＝1.96）.
