动态文本最优化呈现的眼动研究

采用2（呈现方式：平滑滚动引导式、RSVP）×5（呈现速度：120、240、360、480、600字/分）×3（窗口大小：5、10、15字）的多因素混合实验设计,运用EyelinkⅡ眼动仪对汉语动态文本阅读过程进行研究。结果发现,呈现速度较快（≥360字/分）时,与RSVP条件相比,被试在平滑滚动引导式条件下的平均注视时间短、注视次数多、眼跳距离小,阅读理解率高,且被试更偏爱此种呈现方式;呈现速度较慢（≤240字/分）时,两种呈现方式在平均注视时间和注视次数上没有差异。在平滑滚动引导式下,被试在三种窗口大小中各项指标上没有差异;在RSVP条件下,与5字窗口相比,大窗口（10字或15字）条件下平均注视时间更短。     

显示方式对小学生阅读动态文本的影响

以小学三年级和五年级学生为被试,在机控速度（240字/分）条件下,如何在单行呈现动态文本以提高小学生的阅读绩效。实验采用2（呈现方式：引导式、RSVP）×2（年级：三年级、五年级）×2（窗口：5字、10字）的多因素混合实验设计。结果发现：（1）在呈现方式上,平滑滚动引导式优于RSVP,更受被试偏爱;（2）在两种呈现方式下,五年级的阅读正确率显著高于三年级;（3）与平滑滚动引导式相比,窗口大小对RSVP的影响更大。     

移动窗口条件下不同工作记忆者阅读差异的眼动研究

采用EyelinkⅡ眼动仪为工具,考察在移动窗口条件下不同工作记忆容量读者的阅读差异。实验为5（窗口大小：1个字、3个字、5个字、7个字、4×25个字）×2（工作记忆容量：高、低）混合设计。结果表明：随着窗口大小的增加,阅读时间、注视次数、眼跳次数显著减少,阅读速度显著加快,眼跳幅度显著增加。与低工作记忆容量被试相比,高工作记忆容量被试能够更好地整合文章信息,进行更有效的阅读。     

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。     

速度、步幅与窗口对引导式中文文本阅读工效的影响

引导式显示是在视觉显示终端(VDT)上呈现动态文本的主要方式之一.本研究考察了显示窗口大小、跳动步幅、显示速度等因素对引导式中文文本的阅读工效的影响.实验中采用了3(跳动步幅,被试内变量)×3(显示速度,被试内变量)×2(显示窗口大小,被试间变量)的混合设计,共有18个被试参加了实验.结果发现(1)跳动步幅、显示速度和窗口大小均影响中文文本的阅读工效;(2)达到最佳阅读工效的实验条件在速度和步幅上分别集中于200～400字/分和1～3字/步.最后本文结合中文阅读的相关眼动研究,对这些结果的成因进行了简要的探讨.     

平滑滚动引导式和快速系列视觉呈现式中文文本阅读工效研究

本研究在机控速度条件下,考察了显示窗口大小(10字和20字)、显示速度(300字／分和600字／分)和文本显示方式(平滑滚动的引导式和快速系列视觉呈现)等因素对VDT中文文本阅读工效的影响。实验结果发现：(1)300字／分的显示速度有利于阅读理解;(2)在本实验条件下,平滑滚动引导式的可读性优于快速系列视觉呈现式。最后,作者结合有关中文眼动研究理论,对上述结果的成因进行了简要探讨。     

字体、字号和词性对汉字认知加工的影响

实验采用2×7×3的混合实验设计,研究词性、字体和字号对汉字认知加工速度的影响。结果表明,词性对高频汉字的认知加工没有显著影响;在七种字体之中,宋体、正楷和黑体的加工速度较快,而行楷、隶书、魏碑和华文彩云的加工速度较慢,字体的主效应显著;字号的主效应虽然不显著,但24号字体和48号字体的加工速度显著快于36号字体。实验结果倾向于支持汉字识别的平行加工说。     

自控速度的平滑滚动引导式和RSVP的文本阅读

考察了在自控速度条件下 ,显示窗口、起始速度和文本显示方式等因素对视频显示终端 (videodisplayter minals,VDT)汉语文本阅读工效的影响。结果发现 :(1)在阅读正确率上 ,VDT文本的平滑滚动引导式优于快速系列视觉呈现 (rapidserialvisualpresentation ,RSVP)方式 ;(2 )阅读速度和阅读理解成绩相互代偿 ,若注重理解正确率 ,宜采用 15 0字 /分的起始速度 ;若兼顾阅读速度 ,宜采用 75 0字 /分的起始速度 ;(3)起始速度、显示窗口和文本显示方式三者共同影响了阅读绩效 ;(4 )机控速度方式的阅读效率优于自控速度方式。     

词切分与字间距对引导式汉语文本阅读工效的影响

采用两个实验分别考察了词切分和字间距对引导式汉语文本的阅读工效的影响。实验结果表明：(1)不同步幅下的阅读工效差异显著,其中3字／步条件下的阅读绩效最高,但词切分并未能提高阅读绩效,其中消失1词／步条件反而妨碍了阅读理解,出现1词／步条件也未能显著提高阅读工效;(2)字间距对汉语文本阅读工效有显著影响;(3)10字窗口下,步幅效应和字间距效应都显著;20字窗口下,二者都不显著。     

可预测性和空格对中文阅读影响的眼动研究

实验采用EyeLink II 眼动仪,以30名大学生为被试,采用2（预测性：高、低）×3（空格：正常无空格、词间空格、非词空格）被试内设计,考察了预测性和空格对中文阅读影响,探讨了模块化理论和相互作用理论的争论。结果发现：词的预测性和空格两因素的主效应显著,但二者之间无交互作用,符合模块化理论的预期。     

Font size modulates saccade-target selection in Chinese reading

In alphabetic writing systems, saccade amplitude (a close correlate of reading speed) is independent of font size, presumably because an increase in the angular size of letters is compensated for by a decrease of visual acuity with eccentricity. We propose that this invariance may (also) be due to the presence of spaces between words, guiding the eyes across a large range of font sizes. Here, we test whether saccade amplitude is also invariant against manipulations of font size during reading Chinese, a character-based writing system without spaces as explicit word boundaries for saccade-target selection. In contrast to word-spaced alphabetic writing systems, saccade amplitude decreased significantly with increased font size, leading to an increase in the number of fixations at the beginning of words and in the number of refixations. These results are consistent with a model which assumes that word beginning (rather than word center) is the default saccade target if the length of the parafoveal word is not available.     

Writing and reading training effects on font type and size preferences by students with low vision

The effect of writing and reading training on preferred font type and size in low-vision students was evaluated in 35 children. An ophthalmologist confirmed low vision according to ICD-10-CM. Children identified the font type and size they could best read. The writing subtest of the Jebsen-Taylor Hand Function Test, read in 1 min., and legibility as measured by the number of readable written letters were used in evaluating the children. A writing and reading treatment program was conducted, beginning with the child's preferred font type and size, for 3 months, 2 days per week, for 45 min. per day at the child's school. Before treatment, the most preferred font type was Verdana; after treatment, the preferred font type and size changed. Students had gained reading and writing speed after training, but their writing legibility was not significantly better. Training might affect the preferred font type and size of students with low vision. Surprisingly, serif and sans-serif fonts were preferred about equally after treatment.     

Memory predictions are influenced by perceptual information: evidence for metacognitive illusions

Although perceptual information is utilized to judge size or depth, little work has investigated whether such information is used to make memory predictions. The present study examined how the font size of to-be-remembered words influences predicted memory performance. Participants studied words for a free-recall test that varied in font size and made judgments of learning (JOLs) for each item. JOLs were influenced by font size, as larger font sizes were given higher JOLs, whereas little relationship was evident between font size and recall. The effect was modified when other, more valid, sources of information (e.g., associative strength) were available when JOLs were made and persisted despite experience with multiple study-test sessions, use of a forgetting scale to assess predictions, and explicit warning of participants that font size has little effect on memory performance. When ease of reading was manipulated, such that large font size words were made less fluent, the effect was eliminated. Thus, highly accessible perceptual cues can strongly influence JOLs, likely via encoding fluency, and this effect can lead to metacognitive illusions     

儿童社交回避行为：成因、测量方式及适应功能

社会退缩行为是指儿童在社会情境中抑制自己参与同伴互动并表现出独处的行为。根据不同的社交动机,社会退缩行为包含多种亚类型,其中社交回避行为这一亚类型指儿童总是表现出主动避免各种社交场合的行为。总体而言,社交回避是目前研究最少的一种,其形成的主要原因可能是由于儿童本身较高的抑郁感所致,而研究者已开始尝试以间接和直接的方式测量其水平。来自以变量为中心和以个体为中心的研究分别表明,社交回避儿童面临着最高的适应风险。鉴于这一研究领域的广泛前景,未来的研究亟需关注社交回避影响儿童适应的过程机制及其年龄发展特点,测量工具的进一步开发,直接的跨文化比较以及社交回避的干预方案开发。

字词视觉空间特征在中文阅读眼动控制中的作用

研究采用4（呈现方式：小－小、小－大、大－小、大－大）×2（文本内容：句子、“※”串）的被试内设计,考察了文本字符呈现大小对读者眼跳选择目标和注视持续时间的影响。结果发现：（1）读者在浏览不同呈现方式的“※”串时的眼动模式基本上与阅读相应呈现方式的句子类似;（2）句子完全是由双字词构成,词内的首字和尾字大小不等（‘小－大”和“大－小”呈现条件）严重影响阅读效率;（3）读者在阅读句子时的注视时间高于浏览“※”串时的注视时间。结果说明,视觉呈现方式和词汇加工均影响读者的眼动模式。     

Eye movements,the perceptual span,and reading speed

The perceptual span or region of effective vision during eye fixations in reading was examined as a function of reading speed (fast readers were compared with slow readers), font characteristics (fixed width vs. proportional width), and intraword spacing (normal or reduced). The main findings were that fast readers (reading at about 330 wpm) had a larger perceptual span than did slow readers (reading about 200 wpm) and that the span was not affected by whether or not the text was fixed width or proportional width. In addition, there were interesting font and intraword spacing effects that have important implications for the optimal use of space in a line of text.     

Dynamic presentation of magnified graphical characters on the IBM-compatible computers

Software that provides extremely smooth gliding and scrolling of magnified characters and pictograms on standard PCs is described. The program was designed as a tool for reading research, as a computer aid for visually impaired readers, and as a subtitle generator for multimedia applications. Change of font, size of characters, speed, color, and direction of movement can be made interactively. The system is useful for reading remediation and for creation of various visual effects.     

汉语阅读眼动控制:20年研究的总结

本文系统总结了20年来汉语阅读眼动控制的研究成果。在阅读过程中眼动控制主要回答两个问题:(1)哪些因素决定眼睛的注视时间(when);(2)哪些因素决定眼睛的注视位置(where)。对于第一个问题,已有研究从词边界信息、词频、熟悉性、预测性、语义透明度、具体性、非注视词的特性、词汇获得年龄进行了探讨;对于第二个问题,已有研究从汉字字号、笔画数、字结构、词长、词结构、词间空格、词频、预测性、合理性、年龄和阅读能力进行了探讨。通过比较发现,汉语阅读的眼动控制特点与拼音文字的眼动控制特点既有共同之处,又有差异之处。因此,汉语阅读的研究者需要在现有眼动控制模型的基础上,构建适合于汉语特性的眼动控制模型。
