ABSTRACT
In the process of reading, the eye moves over text with saccadic movements. This statement is about the only indisputable one that can be made about eye movements during reading. I will suggest and elaborate three different models which describe the processes that determine the direction and distance moved in each saccade. These models are not original with me although I have talked about them before (Haber, 1972), and Rayner (1974) has described them in related terms. However, because they have not been presented at this conference, I feel it will be most useful to describe them in some detail, hopefully as a means to interpret the earlier papers on eye movements in reading and as a guide to badly needed further research.
