Relationship between the Mental and Physical Growth of Girl

Abstract

Report II contains the results of the research concerning the changes in girl body types in the growing process, and concerning the differences between physically accelerated and retarded girls.The subjects were 370 girls.The results are as follows: (1) Applying Coerper-Hagen's Method to the girls in the 4 to 17 age-group, we came to the following results :i. There are 13 types of body forms in girls physical growth.ii. The girls in age-groups 6, 7, 10; 11, 12, 13, 14 and 15 tend to belong to Type C.iii. The girls in the 4, 9 and 16 year age-groups tend to belong to Type A.iv. The 8 and 17 year age-groups show no significant diflerences but are widely distributed into 13 types.v. The 5 year-olds tend to belong to Type H.(2) In order to examine the changes of body type in each girl's growing process, we selected the three age-stages of 7, 12 and compared each stage with each body type. Ten per cent of the girls thus selected showed the same body type in each of the three stages. About 20 per cent of this 10 per cent tended to belong either to Type D, J or K.(3) Many writeres say that the maximum growth in bodily height comes at 12 to 13 years of chronological age. Our research showed, however, that some have their maximum growth in bodily height at 5 to 6 years of chronological age.
