不同年级学生阅读知觉广度及预视效益的眼动研究

本研究以小学五年级学生和大学生为被试, 采用眼动技术, 从阅读知觉广度和副中央凹预视效益相结合的角度考察读者在阅读过程中一次注视获得信息的情况。实验一采用呈现随眼动变化技术探讨了不同年级学生一次注视获取信息的范围, 即阅读知觉广度。实验二采用边界范式进一步考察不同年级学生在知觉广度范围内, 副中央凹预视获取信息的类型。研究发现, 大学生读者知觉广度范围较大, 能够在副中央凹预视中获取字形和语音的信息, 而小学生读者的知觉广度范围较小, 在副中央凹预视中仅能获取字形的信息。上述结果表明, 不同年级学生在注视时, 获取信息的范围及在副中央凹预视时获取信息的类型上均存在一定差异。

使用Eyelink2000型眼动仪,采用经典的呈现随眼动变化技术,对24名被试在不同窗口条件下英文阅读的眼动指标进行记录和分析,以考察小学五年级学生英语阅读的知觉广度。研究结果表明:小学五年级学生英语阅读的知觉广度的右侧范围是注视点右侧5-8个字符空间。     

不同水平五年级维吾尔族学生母语阅读知觉广度

本研究以眼动仪为工具,借助移动窗口技术,比较了16名高阅读水平和14名低阅读水平的五年级维吾尔族小学生维吾尔语阅读知觉广度的大小及其对称性。结果发现:高阅读水平学生的知觉广度为注视点左侧8~11个字符到右侧2~3个字符,而低阅读水平学生的知觉广度为注视点左侧8~11个字符到右侧2个字符。在本研究条件下,可得出以下结论:(1)五年级不同阅读水平的学生维吾尔语阅读知觉广度都具有不对称性,左侧范围大于右侧;(2)阅读水平高的学生其阅读知觉广度略大于低阅读水平的学生,差异主要体现在右侧知觉广度。

本研究的目的是比较小学生与大学生在口算时间和广度上的差异。30名大学生和30名6年级小学生接受了口算实验。结果显示：（1）大学生口算的广度明显大于小学六年级学生的口算广度。数字广度也大于小学生,但两者差异不显著;（2）在减法和除法的口算时间上,大学生明显短于小学六年级学生,但在乘法口算上无显著差异。     

大小字号的文本对中文读者眼动模式和阅读知觉广度的影响

摘 要 研究以眼动仪为工具,采用移动窗口范式考察不同字号文本对读者阅读知觉广度和眼动模式的影响。实验结果发现,被试阅读大、小字号文本时的阅读知觉广度都是四个字。字号大小不影响读者的阅读知觉广度,但是影响读者的眼动模式。具体表现为：被试阅读小号字文本的平均注视时间、总注视时间比大号字文本长,平均眼跳距离更短,相对眼跳距离（单位为字的个数）更长,注视次数更多。

Targeting regressions: Do readers pay attention to the left?

The perceptual span during normal reading extends approximately 14 to 15 characters to the right and three to four characters to the left of a current fixation. In the present study, we investigated whether the perceptual span extends farther than three to four characters to the left immediately before readers execute a regression. We used a display-change paradigm in which we masked words beyond the three-to-four-character range to the left of a fixation. We hypothesized that if reading behavior was affected by this manipulation before regressions but not before progressions, we would have evidence that the perceptual span extends farther left before leftward eye movements. We observed significantly shorter regressive saccades and longer fixation and gaze durations in the masked condition when a regression was executed. Forward saccades were entirely unaffected by the manipulations. We concluded that the perceptual span during reading changes, depending on the direction of a following saccade.     

Development of the letter identity span in reading: evidence from the eye movement moving window paradigm

By means of the moving window paradigm, we examined how many letters can be identified during a single eye fixation and whether this letter identity span changes as a function of reading skill. The results revealed that 8-year-old Finnish readers identify approximately 5 characters, 10-year-old readers identify approximately 7 characters, and 12-year-old and adult readers identify approximately 9 characters to the right of fixation. Comparison with earlier studies revealed that the letter identity span is smaller than the span for identifying letter features and that it is as wide in Finnish as in English. Furthermore, the letter identity span of faster readers of each age group was larger than that of slower readers, indicating that slower readers, unlike faster readers, allocate most of their processing resources to foveally fixated words. Finally, slower second graders were largely not disrupted by smaller windows, suggesting that their word decoding skill is not yet fully automatized.     

When preview information starts to matter: Development of the perceptual span in German beginning readers

How is reading development reflected in eye-movement measures? How does the perceptual span change during the initial years of reading instruction? Does parafoveal processing require competence in basic word-decoding processes? We report data from the first cross-sectional measurement of the perceptual span of German beginning readers (n = 139), collected in the context of the large longitudinal PIER (Potsdamer Intrapersonale Entwicklungsrisiken/Potsdam study of intra-personal developmental risk factors) study of intrapersonal developmental risk factors. Using the moving-window paradigm, eye movements of three groups of students (Grades 1–3) were measured with gaze-contingent presentation of a variable amount of text around fixation. Reading rate increased from Grades 1–3, with smaller increases for higher grades. Perceptual-span results showed the expected main effects of grade and window size: fixation durations and refixation probability decreased with grade and window size, whereas reading rate and saccade length increased. Critically, for reading rate, first-fixation duration, saccade length and refixation probability, there were significant interactions of grade and window size that were mainly based on the contrast between Grades 3 and 2 rather than Grades 2 and 1. Taken together, development of the perceptual span only really takes off between Grades 2 and 3, suggesting that efficient parafoveal processing presupposes that basic processes of reading have been mastered.
