The bearing of these conceptions on the various quantitative definitions of tested deficiency, including the percentage definition, will then be discussed in the following chapter. Practical advice as to individual diagnosis or group comparisons has been confined to Part One, so that those who are not concerned with the theoretical assumptions on which the conception of mental development and the interpretations of tested deficiency are based should omit Part Two.

To simplify the discussion I have presented in Fig. 3 the graphic picture of the conditions on the simplest hypothesis, namely, that mental capacity at each age is distributed in the form of the normal probability curve extending to zero ability and that individuals retain...
