In this gating study Julia Krebs, Dietmar Roehm and their colleagues Ronnie Wilbur and Phillip Alday investigate which cues within the visual signal resolve local ambiguity in Austrian Sign Language (ÖGS). Disambiguation is triggered earlier than expected based on theoretical descriptions of sentence structure in sign languages. Non-manual markings and/or the transitional movement towards the disambiguating sign are assumed to have resolved ambiguity in ÖGS. Although the ultimate role of these visual cues leading to disambiguation requires further investigation, the present study shows that they contribute crucial information about argument structure during online processing. This finding provides strong support for granting these cues some degree of linguistic status.
