German children’s processing of morphosyntactic cues in wh-questions

Abstract

ABSTRACTTwo experiments investigated the effects of case and verb agreement cues on the comprehension and production of which-questions in typically developing German children (aged 7–10) and adults. Our aims were to determine (a) whether they make use of morphosyntactic cues (case marking and verb agreement) for the comprehension of which-questions, (b) how these questions are processed, and (c) whether the presence and position of morphosyntactic cues available for the listener influence the speaker’s production of which-questions. Performance on a picture selection task with eye tracking shows that children with low working memory make less use of morphosyntactic cues than children with high working memory and adults when interpreting object questions. Gaze data of both groups reveal garden-path effects and revisions for object and passive questions, which can be explained by a constraint-based account. Furthermore, children’s difficulties with object questions are related to the type of disambiguation cue. In a question elicitation task with patient-initial items, children overall prefer production of passives, whereas adults’ productions depend on the availability of disambiguation cues for the listener.
