Experiments on the rationale of the Szondi test.
An attempt was made to investigate the theoretical basis of the Szondi test by obtaining, experimentally, identifications of the Szondi pictures. The Description and Matching methods used correspond to those adopted by American investigators, but were employed for the first time on groups of English subjects.

The results show that although, in general, the pictures are not meaningless stimuli, certain factors and particular pictures are more readily identified than others. Homosexuals and Manics are the most frequently identified factors in both tests, the Epileptics being least frequently diagnosed with accuracy. These findings largely confirm the results published by American investigators, although significant differences were found in results obtained respectively from the two different methods.

It is suggested further that facial clues may be important in the determination of responses.

The inequality of stimulus value of particular cards indicates that a complete reorganization of the test is needed. This might now be achieved by a synthesis of the results of several experimental studies available on Szondi theory.
