While observing others in the society, people make explanations and judgements about others’ behaviors. However, thereshould be cultural differences in affecting behavior judgments. The aim of the present study is to examine whether there arecognitive or emotional differences between Eastern and Western cultures while judging other peoples behaviors. Vignettesstimuli and the questions developed by Knutson et al. (2010) were used to measure how Taiwanese participants thinkand react while making behavior judgements. Factor analysis is conducted to compare the results with the original studycompleted in the US. The results revealed that for the Taiwanese participants, emotional aversion was more related tothe norm violation, while for the American participants, according to the original study, aversion was more related to thesocial affect. The results of this comparison have demonstrated cultural differences between Taiwan and the US in howaversion could be evoked by observing others behaviors.
