When linguists talk about grammar, they essentially refer to human ability to produce language. In this module you will learn about different models that have been used to explain the cognitive processes that allow human beings to produce linguistic meaning and structure. At the same time, you will learn about the conceptual mechanisms that trigger language change, language acquisition and ones that may inhibit those processes. You will finally be equipped with some applied knowledge of statistical analysis for linguistic data in RStudio, so that you will also be able to carry out your own case studies independently. Two live online sessions will be devoted to this, respectively in Week 8 and Week 10, in which we will work on two case studies and produce together some results at peer-review publication level.
