Title A Rational Model of Eye Movement Control in Reading
Venue Annual Meeting of the Association of Computational Linguistics
Session Main Conference
Year 2010

A number of results in the study of real- time sentence comprehension have been explained by computational models as re- sulting from the rational use of probabilis- tic linguistic information. Many times, these hypotheses have been tested in read- ing by linking predictions about relative word difficulty to word-aggregated eye tracking measures such as go-past time. In this paper, we extend these results by ask- ing to what extent reading is well-modeled as rational behavior at a finer level of anal- ysis, predicting not aggregate measures, but the duration and location of each fix- ation. We present a new rational model of eye movement control in reading, the cen- tral assumption of which is that eye move- ment decisions are made to obtain noisy visual information as the reader performs ...
