Glenmore: an interactive activation model of eye movement control in reading

Abstract

This paper describes an interactive activation model of eye movement control in reading, Glenmore, that can account within one mechanism for preview and spillover effects, for regressions, progressions, and refixations. The model decouples the decision about when to move the eyes from the word recognition process. The time course of activity in a fixate centre determines the triggering of a saccade. The other main feature of the model is the use of a saliency map that acts as an arena for the interplay of bottom-up visual features of the text, and top-down lexical features. These factors combine to create a pattern of. activation that selects one word as the saccade target. Even within the relatively simple framework proposed here, a coherent account has been provided for a range of eye movement control phenomena that have hitherto proved problematic to reconcile.
