进行了两个实验来检查中央凹处理困难对阅读感知广度的影响。受试者在阅读句子的同时记录他们的眼球运动。通过根据读者当前的注视点改变文本，可以独立地控制中心凹处理难度和中心凹旁单词信息的可用性。在实验1中，中心凹加工难度由词汇频率控制，而在实验2中，中心凹加工难度由句法复杂性控制。在这两个实验中，当中央凹处理困难时，获得的中央凹旁信息较少。我们得出的结论是，知觉跨度是可变的并且注意力受到限制。我们还讨论了该结果对当前阅读中隐蔽视觉空间注意力与眼动控制之间关系模型的影响。
Two experiments were conducted to examine the effects of foveal processing difficulty on the perceptual span in reading. Subjects read sentences while their eye movements were recorded. By changing the text contingent on the reader's current point of fixation, foveal processing difficulty and the availability of parafoveal word information were independently manipulated. In Experiment 1, foveal processing difficulty was manipulated by lexical frequency, and in Experiment 2 foveal difficulty was manipulated by syntactic complexity. In both experiments, less parafoveal information was acquired when processing in the fovea was difficult. We conclude that the perceptual span is variable and attentionally constrained. We also discuss the implications of the results for current models of the relation between covert visual-spatial attention and eye movement control in reading.
