Figure 1.

Example stimulus from Loftus and Mackworth.4 Viewers were presented with scenes, such as a barnyard scene (left), which contained either an informative (e.g., an octopus) or noninformative (e.g., a tractor) object depending on the meaning of the scene. Fixation durations (right) to informative objects were longer than to noninformative objects, reflecting the additional time needed to extract novel, or unexpected information.
