Child Growth

this is a great privilege and honor for me to introduce to the American public the baby teeth which had been worked out in our journeys psychological laboratory under the direction of dr. Carl Bruner and myself the test series has been constructed on the basis of six years research work with children of all age groups we found that very definite characteristics could be stated for each developmental step in childhood and adolescence and we tried to base the tip oral on that performance which was characteristic of each age level within the life span from birth to maturity we found five periods of development the first year of life is the first period and each month has definite characteristics so there is a test for each month separately in the first year the second period covered the second to the fourth year of life only from what water year to the other we find here characteristic differences so there is a test for each quarter and the second year of life our plan is of course to go on with a systematic preparation of tests for the further Asia employing the same basic scheme they are ten performances in each test the child is tested with the test of his own age but also with the tests of two months before and two months later so that each child really goes through 50 / fountain we were showing now some samples of test because that you hear a three-month child the first test which i want to show is it's his social reaction to my eye I look into his eyes and smile at him and he smiles back he did say is now a movement which also a child of it it should be safe during the test performance he did plays experimental movement with his hand watching the movement of his own fingers now I sure this is here and the child should follow my safe she did for a minute third test we show to the child an object because we have to try to catch his look this land so that he really sees the object he is still attracted and hearing my voice and all the time looks at me the child of this period is much more interested in the human being than an object and it's hard to get him interested in object in the presence of human being now he saw the object and he is following the movement of the object with his eyes all right good the next is the body mastery test we hold the child into the prone position and he should hold his head and shoulders erect and the position he looked around pretty well I think all right now we put him again to the lying position and perform the died of a test you put a diaper on his head and he should try in this difficult situation of life to get rid of the hindrance he will display all kinds of disorganized and undirected movements and we're in this age not yet get rid of these hindrance to see that his movement are not yet directed and he also displays movements with the legs which are cost of no help in this situation now the last test which we will show is the feeling of objects as soon as the child of three months touches an object he is again much more interested in the person and the object first we have to get his interest for the object he produces Queen sound which I wish to have in the beginning looking back at the person that's now arrived belongs to the reaction to the person present you hear a seven-month baby first we show him a type and he grasps and that I actively and tries to get it he takes the toy away from the adult displaying the activity which is characteristic for his age second test we give it a paper should take this paper and he should try to change the form of the paper crush it which he does the child younger than his age all you would swing the paper around in an a specific manner by the child of seven months for the first time changes the form of the people in crushing it alright next we give to the child not to object and he should be able to manipulate these two objects at the same time which he does a child younger than his age is only able to manipulate one toy at the same time was the seven-month child even in it relates to toys at the same time next test we haven't stood up and Kevin imitates this movement he imitates the knocking movement all right next the next test is the so-called die of the experiment it put a diaper on the head of the child which is a difficult situation of his life especially in this supported sitting position and he should now try to draw away this diaper and should succeed in getting it away in evening was sitting supported situation she does we call this the mastery of the body in the difficult situation the next test which we will show with this child is pushing away a disagreeable stimulus trying to get rid of something which is just be able for him
