Children’s ability to understand irony is believed to be acquired late compared to other pragmatic skills. To explore this assertion, this article presents a review of four decades of research, to determine the age at which children actually do become capable of understanding ironic utterances, and what the crucial influencing factors are. As this systematic examination of the state of research shows, children do indeed seem to gain an understanding of irony later than other forms of non-literal language. In seeking (...) an explanation for this finding, this article discusses the methodological orientation of previous research. It might be that the predominant use of offline methods, especially metalinguistic judgment tasks, paints a somewhat distorted picture of children’s irony comprehension. The article therefore argues for the use of eye-tracking, and a re-examination of the thesis of late acquisition of irony comprehension in children in the near future. (shrink)
