在阅读时,你的眼睛会看向哪里?眼跳瞄准假说的批判性评价
Where are your eyes going to look during reading? A critical evaluation of saccade targeting hypothesis
摘要:
由PVL的中心重力绘制的基于单词的眼跳的描述由两个证据支柱支持。第一个是发现一个词的初始注视位置类似于正态分布(Rayner,1979)。另一个是在发射场和着陆场之间发现了一个适度的斜率系数(b=0.49,参见McConkie,Kerr,Reddance,& Zola,1988)。本研究通过四个不同眼跳定位策略的模拟实验和一个中文阅读的眼动实验对这两个发现进行了验证。我们表明,目前的理解基于单词的帐户是不确定的,通过显示基于单词的帐户的替代策略,并确定问题的斜率系数的计算。虽然几乎所有的眼动控制在阅读过程中的计算模型都建立在这两个发现,未来的努力应该是针对了解不同的眼跳定位策略的精确贡献,并知道他们的权重可能会有所不同,在绝望的写作系统。
英文摘要:
The word-based account of saccades drawn by a central gravity of the PVL is supported by two pillars of evidences. The first is the finding of the initial fixation location on a word resembled a normal distribution (Rayner, 1979). The other is the finding of a moderate slope coefficient between the launch site and the landing site (b=0.49, see McConkie, Kerr, Reddix, & Zola, 1988). Four simulations on different saccade targeting strategies and one eye-movement experiment of Chinese reading have been conducted to evaluate the two findings. We demonstrated that the current understanding of the word-based account is not conclusive by showing an alternative strategy of the word-based account and identifying the problem with the calculation of the slope coefficient. Although almost all the computational models of eye-movement control during reading have built on the two findings, future efforts should be directed to understand the precise contribution of different saccade targeting strategies, and to know how their weighting might vary across desperate writing systems.
