E-readers are fast rivaling print as a dominant method for reading. Because they offer accessibility options that are impossible in print, they are potentially beneficial for those with impairments, such as dyslexia. Yet, little is known about how the use of these devices influences reading in those who struggle. Here, we observe reading comprehension and speed in 103 high school students with dyslexia. Reading on paper was compared with reading on a small handheld e-reader device, formatted to display few words per line. We found that use of the device significantly improved speed and comprehension, when compared with traditional presentations on paper for specific subsets of these individuals: Those who struggled most with phoneme decoding or efficient sight word reading read more rapidly using the device, and those with limited VA Spans gained in comprehension. Prior eye tracking studies demonstrated that short lines facilitate reading in dyslexia, suggesting that it is the use of short lines (and not the device per se) that leads to the observed benefits. We propose that these findings may be understood as a consequence of visual attention deficits, in some with dyslexia, that make it difficult to allocate attention to uncrowded text near fixation, as the gaze advances during reading. Short lines ameliorate this by guiding attention to the uncrowded span.
电子阅读器正迅速成为与纸质阅读相媲美的主流阅读方式。由于它们提供了纸质阅读无法实现的无障碍阅读选项,对于患有诵读困难等障碍的人来说可能有益。然而,对于这些设备的使用如何影响阅读困难者的阅读情况,我们知之甚少。在此,我们观察了103名患有诵读困难的高中生的阅读理解能力和阅读速度。将在纸质书上阅读与在小型手持电子阅读器设备上阅读进行了比较,该设备每行显示的单词较少。我们发现,与这些个体的特定子集中在纸质书上的传统阅读方式相比,使用该设备显著提高了阅读速度和阅读理解能力:那些在音素解码或高效视觉单词阅读方面最困难的人使用该设备阅读得更快,而视觉广度有限的人阅读理解能力有所提高。先前的眼动追踪研究表明,短行有助于诵读困难者阅读,这表明是短行(而非设备本身)带来了观察到的数据提升。我们认为,这些发现可能是由于一些患有诵读困难的人存在视觉注意力缺陷,在阅读过程中,随着注视点的移动,他们难以将注意力分配到注视点附近不拥挤的文本上。短行通过引导注意力到不拥挤的文本跨度来改善这种情况。
