This tutorial will support researchers who consider using, or have already collected, verbal protocols as data. After discussing the extent to which language can be useful to identify cognitive processes and principles, we will examine each step of the process from data collection via transcription, analysis, and triangulation. The main emphasis will lie on the systematic analysis of linguistic choices, aiming to identify indicators for specific cognitive phenomena that are of interest for the research purpose at hand. Participants are encouraged to contribute actively to this tutorial by bringing ideas and samples from their own research, pertaining to each step of the research process. Email-based communication in advance of the tutorial will ensure a lively and highly interactive tutorial, supporting ongoing research in a practical way rather than theorizing about potential benefits.
