ABSTRACT
The woman fumbling hopelessly with an upside-down cardigan, the man ramming the doorway with the left side of his wheelchair, the person pouring boiling water onto the counter 6 inches away from the teapot: all these people are showing perceptual or praxic deficits of the kind dealt with in this chapter. So is the man who can no longer recognise the faces of his family, the woman who cannot recognise everyday objects until she can touch them, and the woman staring hopelessly at the hairbrush in her hand, not knowing how to carry out the movement necessary for its proper use. Then there is the man who gets lost in the hospital grounds or in his home streets, who cannot navigate from one place to another because he can no longer represent topographical space accurately. There are many more examples of visuospatial, perceptual, and praxic disorders-too numerous to mention in one short chapter.
