Should you sacrifice one man to save five? Whatever your answer, it should not depend on whether you were asked the question in your native language or a foreign tongue so long as you understood the problem. And yet here we report evidence that people using a foreign language make substantially more utilitarian decisions when faced with such moral dilemmas. We argue that this stems from the reduced emotional response elicited by the foreign language, consequently reducing the impact of intuitive emotional concerns. In general, we suggest that the increased psychological distance of using a foreign language induces utilitarianism. This shows that moral judgments can be heavily affected by an orthogonal property to moral principles, and importantly, one that is relevant to hundreds of millions of individuals on a daily basis.

This study examines the effect of proficiency and similarity between the first and the second language on grammatical gender processing in L2. In three experiments, we manipulated gender agreement violations within the determiner phrase (DP), between the determiner and the noun (Experiment 1), the postposed adjective and the noun (Experiment 2) and the preposed adjective and the noun (Experiment 3). We compared the performance of German advanced learners of French to that of French native controls. The results showed a similar P600 effect for native and non-native speakers for agreement violations when agreement rules where similar in L1 and L2 (Experiment 1, depending on proficiency), whereas no effect was found for L2 learners when agreement rules varied across languages. These results suggest that syntactic processing in L2 is affected by the similarity of syntactic rules in L1 and L2.
