Studies on Puberty: Part II. The Pattern of Differential Growth

An Anthropometric Study of Edinburgh Schoolchildren: Part II: Comments on Results

“…The data obtained in this cross-sectional study cannot give inferences about longitudinal growth patterns. The linear trends, however, do not support the conclusion drawn by Cawley, Waterhouse and Hogben (1949) that the mean cephalic index decreases with age in a male population and that before the age of 12 years a female population is on the average more dolichocephalic than a male population.…”

Part Ii: Changes in Head Shape

“…In all three groups the mean cephalic indices are greater for girls than for boys and reach peak values before 12 months. t Cawley, Waterhouse, and Hogben (1949), in a similar study, advocate a fitting procedure in which the perpendicular deviations are minimized. The need for this did not arise in the present case since the smallest of the four correlation coefficients was +0-992 and hence the slopes of the conventional regression lines were indistinguishable.…”
