A cognitive computational model of eye movements investigating visual strategies on textual material

Abstract

This article presents a computational model of the visual stra­tegies involved in processing textual material. An experiment is presented in which participants performed different tasks on a multi-paragraph page (searching a target word, searching the most relevant paragraph according to a goal, memorizing paragraphs). The proposed model predicts eye movements based on 5 parameters. The weighting of parameters is determined for each task by means of a multi­dimensional comparison of participant and artificial scanpaths.
