| Sumario: | This article examines the validity of the Rosenzweig Picture-Frustration (P-F) Study. The three major aims of the study were to determine the effect of frustration upon performance of the P-F Study, to compare results obtained using the Picture-Frustration Study with comparable results secured from the Thematic Apperception Test (TAT), and to compare individuals very high and very low in minority-group prejudice in terms of their performance on the P-F Study. In addition the shift in extrapunitiveness and intropunitiveness following frustration, as measured by these two measures, also failed to correlate. In spite of their failure to correlate with each other the two measures agreed in their relationship to all other variables. Thus, in all cases where the same proposition was tested using evidence from both measures the result of the testing was the same. There are several possible explanations for the failure of the TAT and the P-F Study to correlate under these circumstances First, if it is assumed a true measure of extrapunitiveness, it is possible for both the TAT and P-F Study to correlate with such a measure in the neighborhood of 70 and still, as a result of sampling error, not correlate with each other. Second, there is the possibility that one of the two measures is not actually measuring what it is supposed to measure.
