On the basis of Rorschach analyses of two groups of patients, the authors conclude that schizophrenic cases can be reliably classified into "process" (true or chronic) and "reactive" (benign or acute) groups. Their evidence also leads them to believe that these two groups differ in their "psychological-function characteristics." Further studies of the reactive-process hypothesis are indicated. 20 references. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
