In spoken languages, new information is often expressed with a longer duration than given information. We investigated whether signers use duration to mark information status. Fifty deaf Chinese Sign Language (CSL) signers retold a cartoon clip, and we examined how they tracked references. The results showed that CSL signers mostly used nominals, classifiers and constructed actions, but rarely used any pointing or zero anaphora. When focusing on nominals, newly introduced references had a longer duration than the maintained and re-introduced ones, while the durations of maintained and re-introduced nominals did not differ. Additionally, there was a gradient decrease in sign duration over the first three mentions followed by an increase for the fourth and fifth mentions. Furthermore, between two nominal mentions, the more non-nominal referring there were, the shorter the duration of the current nominal mention. Thus, CSL signers vary the duration of nominals to indicate the degree of accessibility.
