This study examined the effect of a denial of negative information concerning the characteristics of a target person on interpersonal attitudes. More specifically, it investigated whether the denial leads to the revision of both explicit and implicit negative attitude, and whether the degree of the organization of the interpersonal attitude modified the effect of the denial. One hundred and twenty university students participated in the study, and read a negative story of a target person accompanied with a picture of the person. Then, after the manipulations of the organization (high vs. low) of the interpersonal attitude toward the target person and the denial of the negative part of the story (denial vs. no denial), they answered their explicit attitude on the impression rating scales. Furthermore, their implicit attitude toward the target person was measured with an indirect priming paradigm; after presenting a picture (the target person or an unrelated person), the reaction time toward positive and negative words was measured. The recall of the original story was also recorded right after and the after one week of the experiment. The results suggested that the denial of the negative information led to a revision of the explicit attitude but not to a revision of the implicit attitude. It was also suggested that negative information was more dominant in the target person's schema after one week of the experiment. Discussion considered the underlying cognitive mechanism of these results and the implication for the interpersonal and mass communication.
