The study tests the general hypothesis that "rankings of subjects based upon common interpretations of Rorschach score factors applying to an impulsivity-inhibition continuum will correlate significantly with rankings of these subjects by raters from (1) long standing acquaintance with the subjects, and (2) brief behavior samples." Behavioral data were obtained by means of the Rosenzweig P-F Test. Results indicated that the Rorschach contains several factors which have value for the prediction of overt behavior, while other factors do not correlate significantly with behavioral criteria.
