Attitude change was measured on four different topics before and immediately after a persuasion was presented in order to compare the degree of change with the level of ego involvement as it relates to topic controversiality. Ego involvement was based on self-ratings of concern for each topic. Objective topic controversiality was based on the average level of ego involvement in each topic for all subjects. The following hypotheses were upheld: attitude change could be produced, even on highly ego-involving and controversial topics; and the more controversial the topic, the less attitude change would be created by the persuasion. A third hypothesis, that higher levels of subjective ego involvement would produce lower amounts of attitude change, was not supported. (Author)
