Chapter 7 describes the fundamental research questions, empirical approaches and findings of cognitive linguistics & psycholinguistics. This interdisciplinary linguistic subfield comprises a broad range of approaches and theories focusing on the study of language and cognition. For analysing mental representations and processes underlying language production, language comprehension, language acquisition, and non-linguistic thought, key issues of empirical research include considerations on research participants, types of data, and components of experimental research. The chapter ends with recommendations for further reading and a list of short exercises and ideas for small research projects.
