Within CCL we analyze several types of conversational data to investigate the creation of common ground in conversation. Monitoring the exchange of questions and answers can provide important information on how understanding is generated. In conversation, a question exposes the current level of knowledge of the questioner, while the answer, in turn, exposes the responder’s interpretation of the question. In one of our experimental settings – a referential communication task, in which one participant describes pictures of faces for the other to find and place in the correct position – distinct patterns in the use of questions and answers are found, pertaining to underlying linguistic and cognitive functions of the participant. This gives us important insights into the function of various clinical populations. Our dialogic experimental design – instead of individual testing of linguistic and cognitive abilities – also provides a more accurate view on the actual impact of a linguistic deficit. We are currently combining the analysis of question-answer strategies with an eye tracking paradigm to explore non-verbal contributions during conversation.
