~P= toys such as sticks, stones, spools, keys, bslls ané@ blocks. He is slso interested in peck-a-boo amd this-little-pig-went-to-market. Parents should know that this tiny thine eraves security and love. Also the three prime essentials so necessary at this time are activity, rest and food. Now, Dr. Allen, will you cerry us on from the ages of 4 to 6? Allen-- Well, there is « continuation of the first stare in miny essentials. There is 2 rapid growth of the brain md the boy, anc there is great physical activity. There is a further strencthening of the memory. Reasoning and judgment are faulty. This is 2 strong imitstive periad. Also, there is a tendency to begin to nlay with other children. The child is selfish, of course. Every child at this 22e is extrerely selfish, because he is draw- ing into himself an@ he is only interested in himself. Parents should ex- pect this. For his pley activity, the sand pile end moulds enthrall hin. He likes carts, swings, see-saws, anc if it is = little girl, the doll house ana toy furniture eamnesl especially. The boy neturally likes climbing trees ena ladders, an? this is where the younz rother begins to shudder. But, if we believe in G. Stanley Hell's theory that man is an omnibus in which all of his ancestors ride, we can natureliy expect thet this little animal is followinz the cycle of his aneestors. He will rum, jump, leap, vault and clirb. These are the fundementsl activities of man, ond this is exectly the fundamental activity thet we exvect in the growing boy, although the vaulting cores later. Now, Dr. Lapp, the ages of 7 to 9 perheps are worthy of study. Will you outline the advancing changes of this group? Lapp-- In the ages of 7 to 9 we fin? the child jeveloning his permanent teeth, and a slowing up of the brain erosth. There is » slower physical eevelorment end a chunge in the circulatory systam with 2 tendency toward heart weak- nesses ant faticue. In the mental rakeur, we finé interest shifting from action to results, the rersoning power is still week, but the memory is beginning to strenzthen. The younrster kas a very active imagination. His interest aswakens through competition. We still fin? him interested in the sand nile, the see-saw, and the jumping pit. Climbing is still fas- cinating. Games of chasing, hunting, throvine, shooting, as well es the sincine cames annesl to him. Dravetic an¢d constructive sames are the order, Nature plays, lenguaze, reading and spelling sames, together with music, drawing, and seasonal canes heve a very cefinite anneal. Dr. Allen, will you discuss the development of the ass groums from ssy 10 to 12, or 10 to 13? Allen--At these eres, 10 to 13, we find a lessened nhysicsl srowth, and a ravié organic ané functional development. At this time, 5: 3, there is the ereatest desree of immunity from disease, ani we also fink at this sce there is the creetest activity. From the mentol snzle we finc the hero worship stace, the element of coovneration in semes, extreme interest in clubs, secret societies, ent. gags. This is the perio? for memorizing and drill. Concerning pley, we have an excessive desire amont our imerican youth for basketball snd baseball. In the fundamental activity of the younesters we fine elirbine, trapeze work, snd work on rings end bars appeal to him immensely. All types of sares arveal to this nlestic youth. In- tellectual games, nature plays, as well as formal games, dramatic activity and constructive games such as building caves and shacks find a larve place in his active existemce. Chasing zares, such as hi¢e-snd-sesk and hare-ond- hound anneal to this youngster. For the sirls, the ¢rorth is ranid; there is profound change in the organs of the bo’ y; the elimination is often very poor; -
