When actions and looks don't line up: The contribution of referential and prosodic information in the processing of PP ambiguities in child-L2 speakers of English

In two eye tracking experiments, we investigate how adult child-L2 speakers of English resolve prepositional phrase (PP) attachment ambiguity in their dominant language (English), and whether they use prosodic information to aid in the process of garden-path recovery. The findings showed an increased processing cost associated with the revision of temporary ambiguous sentences for the child-L2 adults relative to the native English speakers. When prosody was informative, the child-L2 adults were able to use prosodic information to guide the interpretation of their later acquired, dominant language. However, they performed revision significantly less successfully than the native speakers. Although processing was similar for the native English speakers and the adult child-L2 speakers of English, when it comes to sensitivity to prosodic information and referential context, the two groups differed with regards to reanalysis both in the presence and absence of salient prosodic and referential information.
