In two recent experiments, Wicklund, Cooper, and Linder (1967) have shown that commitment to perform an effortful task in order to hear a counterattitudinal communication will induced attitude change toward the position espoused in the communication prior to both task performance and exposure. Two formulations within dissonance theory lead to opposing predictions about the effect of obtaining commitment to exposure while introducing the effortful pre-exposure task as a fait accompli. Three conditions successfully replicated the findings of Wicklund et al. The fourth condition demonstrated that attitude change does not occur in this setting unless the subject is informed of both the nature of the communication and the effortful pre-exposure task before commitment.
