有两个帐户的读者如何无间距书写系统（例如，中国人）知道在哪里移动他们的眼睛：（a）扫视指向默认目标（例如，作为正在进行的旁视处理的函数，动态地调整已经在旁视a）或（B）中分割的单词的中心。本文报道了支持后一种假设的眼动实验，通过证明在单词N上的扫视发射点和随后在单词N+1上的注视着陆点之间的关系的斜率>1，表明扫视从提供更多旁视处理的发射点延长。然后，通过使用两种假设的实现进行模拟来评估和确认这一结论（Liu，Reichle，& Li，2016），并讨论这些结果，以帮助我们理解阅读期间的扫视目标和现有的眼动控制模型。
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.
