Zusammenfassung

Eye movements in reading are characterized by short periods of steadiness (fixations) followed by fast movements (saccades). Saccades are needed to bring new information into the centre of the visual field where acuity is best; fixations are required to recognize words. Assuming that the central (foveal) word is identified during a fixation, it is tempting to forward the hypothesis that eye movements in reading essentially consist of word-to-word movements. Unfortunately, such a simple sequence of motion is rarely observed in empirical data. Some words are fixated more than once, some are initially not fixated but immediately afterwards regressed to, and some are not fixated at all. Ever since the first measurements of eye movements in reading, researchers have been puzzled by this complicated pattern of activity and have suggested various explanations for it. In this chapter, we will focus on one aspect, namely the fact that more than one third of the words are initially skipped during reading. First, we will discuss the explanations offered by different authors, then we will examine the empirical evidence more closely, and, finally, we will present an alternative account of word skipping. The authors offer a stochastic, non-linguistic model of eye movement control in reading.
