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。     

不同掩蔽材料对阅读知觉广度的影响

采用移动窗口技术,探讨了不同掩蔽材料对中文阅读知觉广度的影响,结果表明：（1）相对于“※”掩蔽,文字掩蔽条件下的阅读效率更低、平均注视时间更长、眼跳幅度更小。（2）“※”掩蔽下被试的知觉广度为注视字左侧1个字,右侧2－3个字;文字掩蔽下被试的知觉广度为注视字左侧1个字,右侧3－4个字。综合上述结果,文字掩蔽材料可以比“※”掩蔽材料获得更大的知觉广度,但阅读效率更低。在中文阅读中,文字掩蔽材料更适合探讨阅读知觉广度

The gaze-contingent moving window in reading: Development and review

The development of the gaze-contingent moving window paradigm (McConkie & Rayner, 1975, 1976) is discussed and the results of the earliest research are reviewed. The original work suggested that the region from which readers can obtain useful information during an eye fixation in reading, or the perceptual span, was asymmetric around the fixation point, and extended from 3–4 letter spaces to the left of fixation to about 14–15 letter spaces to the right of fixation. Subsequent research which substantiated these findings is discussed. Then more recent research using the moving window paradigm to investigate the following topics (1) effects of reading speed, (2) effects of reading skill, (3) effects of the writing system, (4) effects due to age, (5) effects related to deafness, and (5) effects related to schizophrenia is discussed. Finally, some extensions of gaze-contingent paradigms to areas other than reading are discussed.     

藏语阅读知觉广度的眼动研究

不同语体阅读知觉广度的研究由来已久,研究重心多集中于拼音文字和表意文字,已有研究表明阅读知觉广度存在语言加工的特异性。藏语作为拼音文字,同时具有表意文字的特征,是阅读知觉广度研究尚未涉及的语言材料。因此,藏语阅读知觉广度的范围尚不清楚,藏语阅读知觉广度是否也表现出语言加工的特异性也有待证实。为了探测藏语阅读知觉广度的大小,使用Eye Link 1000 Plus型眼动记录仪,以35名在校藏族大学生为被试,采用经典的移动窗口范式,设计了7种窗口(5、9、13、17、21、25和整行)。结果发现,L2R2-L12R12在所有指标的观测值上均存在显著差异,L4R4-L12R12在总注视次数、总注视时间和向右眼跳幅度三个指标的观测值上存在显著差异,L6R6-L12R12在向右眼跳幅度指标的观测值上存在显著差异,L8R8-L12R12在所有指标的观测值上均不存在显著差异,达到了基准水平。结果支持藏族大学生藏语阅读知觉广度的右侧范围大约是注视点右侧4~8个字符的空间。阅读知觉广度存在语言加工的特异性。     

自然阅读与校对阅读的知觉广度研究

采用经典的移动窗口技术,以Eyelink2000型眼动仪为工具,探讨了自然阅读和校对阅读两种不同的任务对中文阅读知觉广度的影响,结果表明：（1）与校对阅读条件相比,自然阅读条件下的阅读速度更快、眼跳幅度更大。（2）自然阅读条件下被试的知觉广度为注视点右侧2-3个字;校对阅读条件下被试的知觉广度仅为注视点1个字的空间。结果说明,读者在校对阅读和自然阅读条件下采用了不同的阅读策略,阅读知觉广度的大小受任务要求的影响。     

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.     

Eye movements and the perceptual span in beginning and skilled readers

Four experiments are reported which examined the size of the perceptual span in second-, fourth-, and sixth-grade children, as well as adult skilled readers. The results indicated that the perceptual span in beginning readers is slightly smaller than the perceptual span of skilled readers. Using a moving window technique, it was found that the perceptual span of beginning readers extends about 11 character spaces to the right of fixation; for skilled readers, the span extends 14-15 spaces to the right of fixation. Beginning readers apparently devote more of their processing to the foveally fixated word than more proficient readers, but their perceptual span appears to be asymmetric to the right of fixation as is the case for skilled readers. The results of the experiments also indicated that the size of the perceptual span is variable and can be influenced by the difficulty of the text. It is concluded that the size of the perceptual span does not cause beginning readers' slow reading rates.     

Lexical quality and eye movements: Individual differences in the perceptual span of skilled adult readers

Two experiments used the gaze-contingent moving-window paradigm to investigate whether reading comprehension and spelling ability modulate the perceptual span of skilled adult readers during sentence reading. Highly proficient reading and spelling were both associated with increased use information to the right of fixation, but did not systematically modulate the extraction of information to the left of fixation. Individuals who were high in both reading and spelling ability showed the greatest benefit from window sizes larger than 11 characters, primarily because of increases in forward saccade length. They were also significantly more disrupted by being denied close parafoveal information than those poor in reading and/or spelling. These results suggest that, in addition to supporting rapid lexical retrieval of fixated words, the high quality lexical representations indexed by the combination of high reading and spelling ability support efficient processing of parafoveal information and effective saccadic targeting.     

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。
