The Israeli-Palestinian conflict has been an ongoing source of violence in the Middle East, claiming the lives of tens of thousands of people. As of late violence has escalated, with this year being one of the deadliest years in the conflict in decades. Therefore, now more than ever finding ways to bridge divides is essential to reduce the human suffering associated with the conflict. In this study we evaluated the impact of an important element of communication: accent. We demonstrate that the accent through which trust-building initiatives are communicated can inadvertently sway public opinion regarding their benefits. Jewish-Israelis listened to the same trust-building proposal communicated by a Palestinian delegate with varying degrees of Palestinian Arabic-accented Hebrew. When the same proposal came from a Palestinian delegate with a heavier accent, Jewish-Israelis thought this proposal was significantly worse for Israel than when it was offered by a Palestinian delegate who spoke Hebrew with no detectable, non-native accent. This effect was explained by differences in how the Palestinian delegate was judged depending on his accent. When the delegate spoke with heavier, Arabic-accented Hebrew, he was judged more harshly than when he spoke Hebrew with no such accent, which in turn reduced how favorably Jewish-Israelis evaluated the proposed measures. Our findings show that the way in which trust-building measures are communicated can shape how they are received and thus has direct implications for diplomatic efforts. [ABSTRACT FROM AUTHOR]

People have false memories that distort their recollection of past events. Language is an important source of such memories, from providing false inferences to outright misinformation. Here we investigate the impact of using a native or foreign language on bilinguals' susceptibility to false memories. Although language has been argued to impact false memories in multiple ways, our study was inspired by recent work in the decision-making literature, which leads to the novel hypothesis that foreign language encourages people to engage in careful memory monitoring that could reduce false memories. This hypothesis contrasts with a processing load account, which predicts that a foreign language would increase false memories because it is naturally more difficult to process information in a foreign language. We tested these hypotheses using two false memory tasks. Using the DRM task, Experiment 1 found that individuals were more accurate in identifying false memories when using their foreign language compared with their native tongue, consistent with the memory monitoring hypothesis. Using the misinformation task, Experiment 2 found that processing misleading information in one's foreign language eliminated false memories, again supporting the hypothesis that a foreign language increases the use of memory monitoring. These findings support a monitoring hypothesis that has been overlooked in prior studies on bilingualism and false memory, with implications for billions of people who regularly use a foreign language.

Longstanding intergroup conflict is one of the most perilous issues on the global stage, leading to violence, displacement, and loss of life. Finding strategies to bring parties to the negotiation table is therefore of utmost importance for conflict resolution. Here we address a common problem in intergroup conflict - the lack of a shared, native tongue - which is typically solved by using a lingua franca. Three experimental studies revealed that a peace-building proposal presented in a lingua franca is perceived as less favorable to one's own side than a proposal presented in one's native tongue. Specifically, our studies demonstrated that the use of a lingua franca elicits higher levels of hatred and lower levels of sympathy, thereby reducing the perceived favorability of the proposal. Broadly, these findings indicate that the seemingly innocuous choice of the language could have serious implications for conflict resolution as well as for international diplomacy.
