Further Tests of a Dynamic-Adjustment Account of Saccade Targeting during the Reading of Chinese
Liu, Yanping; Huang, Ren; Gao, Dingguo; Reichle, Erik D.
Cognitive Science, v41 suppl 6 p1264-1287 May 2017
There are two accounts of how readers of unspaced writing systems (e.g., Chinese) know where to move their eyes: (a) saccades are directed toward default targets (e.g., centers of words that have been segmented in the parafovea); or (b) saccade lengths are adjusted dynamically, as a function of ongoing parafoveal processing. This article reports an eye-movement experiment supporting the latter hypothesis by demonstrating that the slope of the relationship between the saccade launch site on word "N" and the subsequent fixation landing site on word "N" + 1 is > 1, suggesting that saccades are lengthened from launch sites that afford more parafoveal processing. This conclusion is then evaluated and confirmed via simulations using implementations of both hypotheses (Liu, Reichle, & Li, 2016), with a discussion of these results for our understanding of saccadic targeting during reading and existing models of eye-movement control.
