Syntactic variation in German wh-questions

This paper reports three experiments concerning variation in the grammar of German wh-questions. We found much variation but no clear dialects in the acceptability ratings of sentences violating the weak crossover condition. We attribute this variation to extra-grammatical factors. With a sentence completion task, we were able to show that there is regional variation concerning the scope of wh-movement. In a training experiment, we were also able to make speakers of the restrictive dialect behave like speakers of the liberal dialect with respect to wh-movement. We argue that this suggests an extragrammatical explanation of the dialectal difference.
