| summary | Fixation durations in reading are jointly influenced by visual-acuity constraints and processing difficulty. Frequency, predictability, and length of fixated words are established contributors to fixation durations in reading. Here we show that frequency, predictability, and length of neighboring words as well as incoming and outgoing saccade amplitudes and fixation position in the current word also influence the duration (Kliegl et al., 2006). Sentence-reading data are reported from 222 readers (159,888 fixations). Novel results are simultaneous effects of last and next word frequency and predictability as well as replications of four disputed parafoveal-on-foveal effects. Our computational model of saccade generation, SWIFT, reproduces the observed immediacy, lag, and successor effects (Engbert et al., 2005). Novel lag effects are reproduced with assuming (1) lexical processing tied to limits of the perceptual span and (2) delayed inhibition of saccade programs due to foveal processing difficulty. Novel successor effects are due to spatial selection effects in the perceptual span.
