| summary | Due to random and systematic (or "saccadic range") errors in the
oculomotor system, distributions of within-word landing positions are rather broad and show overlapping tails, which suggests that a fraction of fixations is mislocated and falls on words to the left or right of the selected target word. First, we show that mislocated fixations strongly bias experimentally
observed within-word landing position distributions using a new procedure for the self-consistent estimation of mislocated fixations. Second, we compute better estimates for the size of the saccadic range error in reading. Finally, we use the SWIFT model of saccade generation in reading to test the reliability of the results. As an outlook, we present pilot simulations for alternative
computational principles underlying the saccadic range error. |
