Logical relations and comprehension in conversation.
This study examines how logical relations (e.g., causality and identity) in spoken discourse affect comprehension. Research on cohesion, which shows that specific unit template structures link discourse and text together, is used to build a model of language comprehension that places template structures at the base of a context comparison operation. Subjects were engaged in ordinary conversation with a confederate trained to produce specific types of logical utterances unobtrusively. The comprehension model predicted that systematically different latencies, topical response, and remedial response of subjects would follow the test items produced by the confederate. The data support the predictions. It is shown that comprehension occurs via one processing path if there is a direct tie between the target item and the immediately prior item in discourse, and a separate processing path if the tie is between the target item and the earlier context. Subject response in conversation is shown to display useful evidence on the nature of comprehension achieved. The findings specify and extend the recent research on the integration of new information into a textual structure.
