The study aimed at investigating any bias in the perceptions of young people from two ethnic groups who were not directly involved in an ethnic conflict. Assuming that such perception bias only happens in the members of ethnic groups who were involved in the conflict and in those who became the victims of the other group’s transgression. Therefore, we predicted that the subjects from the Dayaknese group would evaluate the photos of their own group members more positively compared to their perception of the Madurese photos. Meanwhile, there would be no bias among Madurese students in evaluating both Dayak and Madura photos. An experimental approach was carried out using photos of neutral faces of Dayaknese and Madurese people. Each photo was presented with negative or positive words. The participants of the study comprised 111 students who represented Madurese and Dayaknese ethnic groups, as well as Javanese who had not been involved in the conflict serving as the control group. They were asked to evaluate the photos in terms of the negativity and positivity of each picture. A two-way ANOVA supported the hypothesis that the Dayaknese evaluated their own groups better than the other ethnic groups, while the Madurese did not.

先前冲突中属于种族的学生之间的情感反应

这项研究的目的是调查没有直接参与种族冲突的两个族裔对年轻人的看法的偏见。假定这种看法偏见只发生在参与冲突的族裔群体的成员中，以及成为另一种族群犯罪的受害者的族裔群体中。因此，我们预测，与他们对Madurese照片的感知相比，Dayaknese组的主题将更积极地评估其自身成员的照片。同时，Madurese学生在评估Dayak和Madura照片方面不会有偏见。使用Dayaknese和Madurese人的中性脸照片进行了实验。每张照片都带有否定或肯定的词。该研究的参与者包括代表Madurese和Dayaknese族裔的111名学生，以及未参加冲突的爪哇人（作为对照组）。他们被要求根据每张照片的负性和正性来评估照片。双向方差分析支持以下假设：达雅克尼人对自己的群体的评价优于其他种族，而马杜雷塞人则没有。
