A further investigation of the pretest-treatment interaction effect

Abstract

What effect does a pretest have on a study of an attitude-treatment when the topic is of great concern to the Ss? Segregation and vivisection were the topics in comparing pretest-treatment interaction. 224 college students plus 100 others were used as Ss. "Apparently, an attitudinal pretest has no effect on the reception of a succeeding persuasive communication within the limits of involvement of S with the topical continuum represented by vivisection… at one point and ethnic prejudice at another."
