An eye-movement study was conducted to examine whether Chinese readers immediately activate and integrate related background information during discourse comprehension. Participants were asked to read short passages, each containing a critical word that fitted well within the local context but was inconsistent or neutral with background information from the early part of the passage. This manipulation of textual consistency produced reliable effects on both first-pass reading fixations in the target region and second-pass reading times in the pre-target and target regions. These results indicate that integration processes start very rapidly in reading text in a writing system with properties that encourage delayed processing, suggesting that immediate processing is likely a universal principle in discourse comprehension.
