Abstract
In a study involving 62 Danish children with autism spectrum disorder, we obtained results showing that the mastery of linguistic recursion is a significant predictor of success in second-order false belief tasks. The same study also showed that the mastery of linguistic recursion was not significantly correlated with success in a task involving three heavily used Danish discourse particles. This calls for further explanation, as the reasoning involved in both types of tasks seems similar. In this paper, we discuss second-order false belief reasoning, the reasoning underlying the use of the three Danish discourse particles, say what we know about them experimentally, and discuss what they do have in common.
