It's worth noting here that they demonstrated this effect with language learners i.e. it's very likely that the students had to labouriously work out the foreign language questions. Basically they've demonstrated that if people spend a lot more time on a question they answer less emotionally (which seems like it would be true independent of the language). If they can demonstrate the effect still holds with 2nd language speakers with native level proficiency then this would be a lot more interesting result.
