This seminar focuses on how experimental syntax is a valid tool to derive syntactic theory. In particular, we will explore the relationship between acceptability judgments and the form and nature of grammatical knowledge. We will learn about theories behind experimental syntax and we will analyze how acceptability judgment studies have been performed in different scientific articles to investigate distinct linguistic phenomena. Additionally, students will be working in groups to carry out their own linguistic experiment, i.e., students will create experimental stimuli and collect judgments from speakers. The results of these analyses will be presented in the seminar. For those students who need to write a term paper, the results will additionally be submitted in a written format as part of a larger research activity.
