Motives, values and moral judgments

This study examined McClelland's (1981) hypothesis that operant and respondent measures of personality are orthogonal and assess different dimensions of personality structure. An operant measure of motives, a sentence completion test, and two respondent measures of cognitive schema variables, the Rokeach Value Survey and the Defining issues Test, were administered to 311 subjects. As predicted and in support of McClelland's hypothesis, 69% of the correlations between the respondent measures were significant at the alpha .05 level of probability versus 14% of the correlations between the operant and respondent measures. Further, within the domain of cognitive schema variables, it was theoretically possible to predict which values would correlate with different levels of moral judgment. The findings were discussed in terms. of their implications for person x situation models of social interaction and the prediction of criterion variables from typologies of personality.
