The return of the repressed: Abandoned parses facilitate syntactic reanalysis

Two eye movement experiments examined effects on syntactic reanalysis when the correct analysis was briefly entertained at an earlier point in the sentence. In Experiment 1, participants read sentences containing a noun phrase coordination/clausal coordination ambiguity, while in Experiment 2 they read sentences containing a subordinate clause object/main clause subject ambiguity. The critical conditions were designed to induce readers to construct the ultimately correct analysis just prior to being garden-pathed by the incorrect analysis. In both experiments, the earliest measures of the garden path effect were not modulated by this manipulation. However, there was significantly less regressive re-reading of the sentence in those conditions in which the correct analysis was likely to have been constructed, then abandoned, at an earlier point. These results suggest that a syntactic analysis that is abandoned in the course of processing a sentence is not lost altogether, and can be re-activated or retrieved from memory. Implications for models of initial syntactic analysis and reanalysis are discussed.
