视觉跨度对阅读速度和句子阅读过程中眼球运动的中央凹处理的影响
作者：
摘要：在单字快速连续视觉呈现任务中，视觉广度(或称“非拥挤窗口”)决定了阅读速度，它限制了每个注视的感觉信息。本研究调查了当所有单词同时呈现时，句子阅读过程中的注视持续时间是否也是如此，并且在注视之前对单词进行旁中央凹预览通常会减少以后的单词识别时间。如果是这样的话，更大的视觉跨度可能会允许更有效的副中央凹处理，从而更快地阅读。为了验证这一假设，研究人员收集了60名受试者的视觉广度轮廓(VSP)，并将其与眼球跟踪阅读实验中的数据相关联。研究结果证实，读者的VSPs与基于注视的阅读速度呈正相关。然而，这种关系并不是由旁凹加工决定的。没有证据表明VSP的个体差异预示着黄斑旁预览收益的差异。然而，预览收益与阅读速度相关，这表明阅读过程中对眼球运动控制有独立影响。综上所述，本研究结果表明，视觉广度、黄斑旁加工和阅读速度之间的关系比最初假设的更为复杂。
Abstract:Abstract The visual span (or “uncrowded window”), which limits the sensory information on each fixation, has been shown to determine reading speed in tasks involving rapid serial visual presentation of single words. The present study investigated whether this is also true for fixation durations during sentence reading when all words are presented at the same time and parafoveal preview of words prior to fixation typically reduces later word-recognition times. If so, a larger visual span may allow more efficient parafoveal processing and thus faster reading. In order to test this hypothesis, visual span profiles (VSPs) were collected from 60 participants and related to data from an eye-tracking reading experiment. The results confirmed a positive relationship between the readers' VSPs and fixation-based reading speed. However, this relationship was not determined by parafoveal processing. There was no evidence that individual differences in VSPs predicted differences in parafoveal preview benefit. Nevertheless, preview benefit correlated with reading speed, suggesting an independent effect on oculomotor control during reading. In summary, the present results indicate a more complex relationship between the visual span, parafoveal processing, and reading speed than initially assumed.
