horizon of expectations

horizon of expectations, a term used in the reception theory of Hans Robert Jauss to designate the set of cultural norms, assumptions, and criteria shaping the way in which readers understand and judge a literary work at a given time. It may be formed by such factors as the prevailing conventions and definitions of art (e.g. decorum), or current moral codes. Such ‘horizons’ are subject to historical change, so that a later generation of readers may see a very different range of meanings in the same work, and revalue it accordingly.
