Table 1.
The definitions that must be made and empirical patterns demonstrated to document a case of ADP. (See text for definitions. In keeping with the text, the empirical patterns have been stated in terms of dichotomous variables. They can be straightforwardly translated into general linear model form for continuous empirical cases. For example, the second requirement translates as the need for a significant regression coefficient of P on I, and the third line as the need for a significant interaction between P and I in predicting w.)
