Our preferences are influenced by the presence of others. However, it is unclear how the simultaneous presence of multiple others influences preference judgment. In this study, we presented multiple happy or disgust face images around a target and examined their influence on target preference. In Experiment 1, we presented only happy or disgust faces in order to examine the influence of quantity. In Experiment 2 and 3, we manipulated the ratio of happy or disgust and neutral faces. Findings revealed that the happy face increased the target preference and its effect varied by the ratio of happy faces. On the other hand, the disgust face decreased the target preference only if there was one such face. These results indicate that although the numeric information of others’ facial expressions influences preference judgment, this influence differs with the nature of others’ expressions.
