Linguistic illusions have played an important role in our understanding of how our brains process language. By showing where people are "fooled" by linguistic illusions, we can learn about how linguistic representations are mentally constructed. In this talk, I will show how to make a linguistic illusion appear and disappear, providing new insights into how we encode and navigate complex linguistic representations. In particular, the profile of successes and failures informs our understanding of the mental architecture of language, and the interaction between linguistic representation and working memory processes.
