Further Observations on Apraxia

In dealing with the question of visual impairment in cases of so-called constructional apraxia in a previous paper, I had occasion to discuss arguments put forward by Erich Feuchtwanger, who had proposed to abandon the term “apraxia” for this condition and to call the disturbance “agnosia”. My conclusion was in favour of the original concept of Kleist, who had put the ailment among the apractic syndromes. This, however, makes a detailed analysis of the motor activities and their disturbance in constructional apraxia necessary in order to define its place among the known kinds of apraxia.
