Computer-mediated intergroup contact (CMIC) is a valuable strategy to reduce negative sentiments towards members of different social groups. We examined whether characteristics of communication media that facilitate intergroup encounters shape its effect on out-group attitudes. Specifically, we propose that concealing individuating cues about out-group members during CMIC increases prejudice, as interaction partners are perceived as less socially present. To assess these hypotheses, we conducted two mixed-factorial experiments.Participants engaged in synchronous text-chat with out-group members (Study 1) and a confederate (Study 2) who either shared or concealed their name and photo. Overall, CMIC reduced negative out-group sentiments. Study 2 showed, however, that out-group members' anonymity decreased perceived social presence, which was associated with less positive evaluations of the CMIC and higher prejudice. In conclusion, CMIC can contribute to conflict resolution interventions, preparing individuals for direct intergroup contact, if its affordances or conversation topics enhance interaction partners' social presence.Keywords: intergroup contact, prejudice, anonymity, social presence, computer- (Postmes, Spears, & Lea, 1998, 2002. At the Center for Multiculturalism and Technology in Israel, for instance, computer-mediated communication (CMC) services facilitated exchanges between secular Jewish, Orthodox Jewish, and Arab-Islamic teachers (Hoter, Shonfeld, & Ganayim, 2009). After initial text-chats teachers used audio and then video conferencing to engage with out-group members. Following the online intergroup interactions, teachers expressed less prejudice towards the most unfavorable out-group.Negative attitudes of religious Jews towards Muslims were reduced, as were Muslims' negative attitudes towards religious and secular Jews (Walther, Hoter, Ganayem, & Shonfeld, 2015).Intergroup contact certainly is a powerful strategy to overcome conflict and engender harmonious relations between social groups (Allport, 1954;Pettigrew & Tropp, 2006). In addition to a substantial literature attesting to the impact of direct, face-to-face intergroup encounters, empirical evidence (Alvídrez, Piñeiro-Naval, Marcos-Ramos, & Rojas-Solís, 2015;Schwab & Greitemeyer, 2015;Tynes, Giang, & Thompson, 2008;Walther et al., 2015;White, & Abu-Rayya, 2012;White, Abu-Rayya, & Weitzel, 2014;White, Abu-Rayya, Bliuc, & Faulkner, 2015) as well as evaluations of internet-based conflict reconciliation programs (Abbott, Austin, Mulkeen, & Metcalfe, 2004;Hoter et al., 2009;Stock et al., 2009) suggest that computer-mediated intergroup contact (CMIC) can as well promote positive out-group attitudes.

3The present research extends this work and highlights conditions that moderate the effect of CMIC on prejudice. Specifically, we sought to assess whether characteristics of communication media, such as social media platforms, chat tools, or email services, that enable compute...
