If a mother is anxiously watching thecourse of a serious illness of her child and if, in cariiig for it,she is stimulated to the utmost to perform motor- acts, she willcontinue in a state of motor tenseness until the child recoversor dies. If relief is suddcm, as in the crisis of pneumonia,and the mother is not exhaiisted, she will easily laugh; iftired, she may cry. If death occurs, the stimuhis to motoracts is suddenly withdrawn and she then cries aloud, andperforms many motor acts as a result of the intense stimula-tion to motor activity which is no longer needed in thephysical care of her child. With this clue we can find the. Fig. 33.—Laughing Child. This babj is trying to seize the toy with which his sister is playing and finds relief in continuous activation. 103
