When the patient has in some measure recuperated,
he may try the following exercises in mental concentration. Vittoz claims good results from them, but they must be done quite seriously.
1. Walk a few steps with the definite idea that you are putting forward right and left feet alternately. Go on by easy stages until you concentrate on the movement of the whole body.
2. Take any object in your hand, and note its exact form, weight, colour, etc.
3. Look in a shop-window while you count ten, and as you walk on, try to recall all the objects therein exhibited.
4. Accustom yourself to defining the sounds you hear, and concentrating on a special one, as that of a passing tram, or a ticking watch.
5. Make a rapid examination several times daily of your feelings and thoughts, and try to express them definitely.
6. Concentrate on the mental reproduction of a regular curve: a figure 8 placed on its side.
7. Listen to a metronome, and, a friend having stopped it, mentally repeat the ticking to time.
8. Whenever you handle anything, try to retain the impression of that object and its properties for several minutes, to the exclusion of other ideas.
