q1 i? There is slight evidence that inter-test correlations are lower for children of a given age than for adults, with the magnitude and material-dependence of the difference unknown. → Pressey 1920

q1 · i? · associational · r?

Authors' preliminary observational statement, explicitly hedged for lack of quantitative data. The authors note that if the difference is established with more factual material, its explanation would shed light on the general problem of intelligence, and that such research requires very accurate sampling of subjects and is very difficult on a small scale.

"there is some slight evidence that inter-test correlations are lower for children of a given age than for adults. We have little data of a quantitative kind to show how great this difference is, neither do we know how these relationships behave for various kinds of test material."
