本研究探讨了在阅读任务中，好读者和差读者的字母识别广度。16名五年级的孩子在阅读阴极射线管中的段落时，他们的眼球运动受到监控。在阅读期间，在选定的注视点上，显示器的某些区域中的字母被其他字母替换。这种操作在视野的特定区域提供了错误的文本。研究结果表明，两组人都从文本区域获得了字母信息，从注视中心左侧的两个字母延伸到右侧的六个或七个字母。没有证据表明，熟练的读者利用字母信息，从更广泛的文本区域比能力较低的读者。这些发现对阅读中的信息处理理论和眼引导理论具有重要意义，特别是本研究首次比较了当周边信息被破坏但中央凹信息保持完整时好读者和差读者的表现。
THIS STUDY investigated the span of letter recognition for good and poor readers during a reading task. Sixteen fifth-grade children read passages from a cathode-ray tube as their eye movements were monitored. On selected fixations during reading, letters in certain regions of the display were replaced by other letters. This manipulation provided erroneous text in specific regions of the visual field. The results of the study indicate that both groups acquire letter information from a region of text extending from two letters to the left of the center of the fixation through to about six or seven letters to the right. There was no evidence to suggest that skilled readers utilize letter information from a wider region of text than do less able readers. The findings have significant implications for theories of information processing and theories of eye guidance in reading, especially as the present investigation is the first to compare the performance of good and poor readers when peripheral information is disrupted but foveal information remains intact.
