Dur ing the l.q20's and o0s: interest in clinical assessment of the "whole man" was treated with conlt.,mpt by the tradit ional a cademic psy'ehologists, whoso mechanis t ic and atomistic conceptual izat ion was focused o n S-B units.

As psychia t ry showed increas ing restlessness with organical ly and symp- tomatical ly oriented taxonomy, there ",',,as a growing d e n m n d for cl inical asess- men t within a d y n a m i c framework. Clinical psychologists were eager to fill this need, a l though unwi l l ing to divorce, themselves from their roots in psychology. In order to unders tand the later devclolmmnts in clinical testing in Americ~L it is necessary t o gain perspect ive on the theoretical conflicts tlmt deve loped lmtwecn clinical and acactcmic psychology, in the Amer ican tudvcrsities dur ing this period.
