'Salience' is a linguistic phenomenon whereby information that is 'given', or 'new', is distributed and presented within a sentence in particular ways that convey its relevance. Although it has been widely described as the speaker's linguistic choices based on the hearer's perspective, it has received less attention as the speaker's manipulations of the hearer's cognitive states. This timely study redresses that balance by analysing several morphosyntactic phenomena in Japanese, drawing on a wide range of authentic language examples.
