Congruity theory and linear models of attitude change.

Evaluated C. E. Osgood and P. H. Tannenbaum's (see record 1955-08361-001) congruity model of attitude change, a regression model derived from the Osgood and Tannenbaum model, and D. R. Heise's (see record 1969-08323-001) 3 general linear models of attitude change, using data obtained from 208 undergraduates. 104 Ss rated 8 3-word (subject, verb, object) sentences 1st, and then rated the individual words. The other Ss rated the individual words 1st. The mean ratings for the 2 groups were compared to obtain the attitude change for each element, and the models were used to predict the change which resulted from the combination of the words into a sentence. Sex differences were found in mean attitudinal evaluations, and the inclusion of higher-order interaction terms increased the predictability of attitude ratings for females more than for males. Heise's Model III was the best predictor of attitude change, followed by his Model II and the regression model derived from the Osgood and Tannenbaum model. The Osgood and Tannenbaum model gave poor prediction of the mean attitudinal changes obtained. (French summary) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
