 One particular patient—D.F.—has now been examined in considerable detail. While D.F. is severely agnosic, she isn’t completely lacking in conscious visual experience. Her capacities to perceive colors and textures are almost completely preserved. (Why just these sub-modules in her temporal cortex should have been spared isn’t known.) As a result, she can sometimes guess the identity of a presented object—recognizing a banana, say, from its yellow color and the distinctive texture of its surface. But she is unable to perceive the shape of the banana (whether straight or curved, say); nor its orientation (upright or horizontal; pointing towards her or across). Yet many of her sensorimotor abilities are close to normal—she would be able to reach out and grasp the banana, orienting her hand and wrist appropriately for its position and orientation, and using a normal and appropriate finger grip. Under experimental conditions it turns out that although D.F. is at chance when identifying the orientation of a broad line or letter-box, she is almost normal when posting a letter through a similarly-shaped slot oriented at random angles. In the same way, although she is at chance when trying to discriminate between rectangular blocks of very different sizes, her reaching and grasping behaviors when asked to pick up such a block are virtually indistinguishable from those of normal controls. It is very hard to make sense of these data without supposing that the sensorimotor perceptual system is functionally and anatomically distinct from the object-recognition/conscious system.
