Intonational marking of given and new information: Some consequences for comprehension

The role of intonation in conveying discourse relationships in auditory sentence comprehension was investigated in two experiments. Using the simple comprehension time paradigm, Experiment 1 found that sentences with accented new information were understood faster than sentences with a neutral intonation contour and that the presence of accent in context sentences facilitated comprehension of subsequent targets. Both experiments showed faster comprehension times in conditions in which accent placement was appropriate for the information structure of the sentence. In Experiment I, comprehension times were faster when the accent fell on the information focus than when it fell elsewhere in the sentence. In Experiment 2, faster times resulted when new information was accented and given information was not, compared to conditions in which this accent pattern was reversed. This effect held for both active and passive sentences, and whether the new information occurred in the subject or object position.
