Processing gap-filler dependencies in Chinese: What does it tell us about semantic processing?

This study investigates, through gap-filler processing in Mandarin Chinese, whether reanalysis is undertaken to fulfill semantic requirements, even at the expense of structural economy. The construction of interest is Verb+Noun1+de+Noun2, which contains a subject gap and can be ambiguous between a left-branching (relative clause (RC)) and a right-branching (main clause or subject clause) analysis. In the RC analysis, N2 is the filler for the gap. In the right-branching analysis, the gap may co-refer with a noun in the main clause that follows N2 or is interpreted contextually. Sentence completion results showed that the right-branching analysis was initially preferred but the RC analysis increased substantially at the end of the construction. Self-paced reading results indicated that disambiguation in favor of the right-branching analysis in the sentence segment following V+N1+de+N2 produced a longer reading time. These findings suggest that the Chinese parser will trade a structurally simpler (right-branching analysis) for a more complex analysis (RC) to provide a filler for an identified gap and therefore the semantic content for an argument. The overall implication is a human sentence processor allows for reanalysis if it can produce a more meaningful output.
