Evidence

Childs 1915

Childs, H. G. (1915). Measurement of the drawing ability of two thousand one hundred and seventy-seven children in Indiana city school systems by a supplemented Thorndike scale. The Journal of Educational Psychology, 6(7), 391-408. https://doi.org/10.1037/h0075575

q2 · i? · associational · r1

Observation of the curves of progress for both tested systems, measured with the supplemented scale. The author notes this is "completely in accord" with studies of children's drawings by Barnes, Lukens, Burk, and Gotze, who report a plateau of non-development from ages nine or ten to adolescence.

"In both curves the long plateau subsequent to the level reached in grade three is clearly noticeable."
