Abstract
Topic is often marked only by prosody across languages. In sign languages, prosody is expressed by features similar to those in speech: i.e., sign duration, velocity and amplitude of movement (cf. slope and range of pitch). Topicalized signs usually occur sentence-initially, are followed by a pause, and may show longer duration than nontopics. We used pausing and duration characteristics to resolve a puzzle concerning the status of OSV sentences in Austrian Sign Language (ÖGS): are they a nonmanually unmarked variant of non-manually marked topic sentences (O,SV), or are they a within-clause variant of the basic SOV order serving an as-yet-unknown discourse function? We investigated the temporal parameters of prosodic cues of 160 sentences produced by a fluent ÖGS signer: 40 in each of four conditions — SOV, OSV, S,OV, and O,SV. Overt topic marking effects on signing dynamics consisted of (1) lengthening of the sentence-initial topic phrases, causing a delay of the onset of the argument following the topic-marked item, and (2) a shortened duration of the noun phrase following the topic-marked item. Critically, the initial argument of OSV sentences did not show these prosodic cues, indicating that the initial argument O is not treated as being the same kind of topic as in the non-manually marked O,SV sentences. In accordance with the previous literature on pausing and lack thereof, we suggest that OSV might be akin to spoken German scrambling (within-clause movement), although the function performed remains to be investigated. The findings characterize parameters of temporal structure in the physical markers of topic in ÖGS and point to cross-linguistic variability in prosodic marking for topicalized structures.
