Further Observations on Apraxia
This paper gives in rough outline a psychological analysis of motor behaviour in relation to the problem of automatism. An attempt is made to apply Jackson's principle of “reduction to a more automatic condition” in cerebral lesions to cases of apraxia of different kinds. A psychological analysis of constructional tests is given, and the relation of constructional apraxia to other forms of apraxia is illustrated by cases and discussed. The special test of “free construction”, in contrast to constructing with a given pattern, is described and its psychological significance is analysed.
