Perspective effects in repeated reading: An eye movement study

The present study examined the influence of perspective instructions on online processing of expository text during repeated reading. Sixty-two participants read either a high or a low prior knowledge (HPK vs. LPK) text twice from a given perspective while their eye movements were recorded. They switched perspective before a third reading. Reading perspective affected the first-pass reading and also increased sentence wrap-up processing time in the perspective-relevant sentences. Prior knowledge facilitated the recognition of the (ir)relevance of text information and resulted in relatively earlier perspective effects in the HPK versus LPK text. Repeated reading facilitated processing, as indicated by all eye movement measures. After the perspective switch, a repetition benefit was observed for the previously relevant text information, whereas a repetition cost was found for the previously irrelevant text information. These results indicate that reading perspective and prior knowledge have a significant influence on how readers allocate visual attention during reading.     

Interactive braille output for blind computer users

Blind readers were tested using two methods of reading text displayed by an Apple microcomputer. The first method employed an Optacon system, a device that displays tactile representations of single characters, and the second used an interactive single electronic braille cell that displayed grade 1 braille characters. The results demonstrated no difference in accuracy or reading speed between these two methods. Thus, the serial presentation of braille characters at a single position appears to be a viable method of information transfer between computers and braille readers.     

SEMANTIC AND PHONOLOGICAL CODING PROCESSES IN SKILLED AND LESS SKILLED READERS' READING OF TEXT

Abstract

Two experiments examine the memory coding processes of skilled and less skilled readers during the reading of connected text. In experiment 1, students read several paragraphs which required a lexical decision about an underlined letter string within a sentence. Underlined letter strings were either synonyms, repeated words, or control words in reference to items in the sentence. Students were later asked to recall words related to their lexical decision, as well as verify the occurrence of sentences from the text. Skilled readers recalled more synonyms than poor readers, whereas no differences emerged between groups in their recall of other types of words related to the lexical task or for the verification of sentences. Experiment 2 procedures were similar to Experiment 1, except that synonyms were replaced with homophones and the sentence verification task included phrases related to the homophones. When compared to less skilled readers, skilled readers recalled more homophones and repeated words, but were more likely to be disrupted in correct verification of sentences with homophones. Taken together, the experiments suggest that along with phonological coding, semantic processing contributes an important amount of variance to deficiencies in the reading of connected text.     

Effects of word frequency and visual complexity on eye movements of young and older Chinese readers

Research using alphabetic languages shows that, compared to young adults, older adults employ a risky reading strategy in which they are more likely to guess word identities and skip words to compensate for their slower processing of text. However, little is known about how ageing affects reading behaviour for naturally unspaced, logographic languages like Chinese. Accordingly, to assess the generality of age-related changes in reading strategy across different writing systems we undertook an eye movement investigation of adult age differences in Chinese reading. Participants read sentences containing a target word (a single Chinese character) that had a high or low frequency of usage and was constructed from either few or many character strokes, and so either visually simple or complex. Frequency and complexity produced similar patterns of influence for both age groups on skipping rates and fixation times for target words. Both groups therefore demonstrated sensitivity to these manipulations. But compared to the young adults, the older adults made more and longer fixations and more forward and backward eye movements overall. They also fixated the target words for longer, especially when these were visually complex. Crucially, the older adults skipped words less and made shorter progressive saccades. Therefore, in contrast with findings for alphabetic languages, older Chinese readers appear to use a careful reading strategy according to which they move their eyes cautiously along lines of text and skip words infrequently. We propose they use this more careful reading strategy to compensate for increased difficulty processing word boundaries in Chinese.     

A program for comprehension monitoring of text using HyperCard for the Macintosh

We describe a program using HyperCard for the Macintosh that allows the collection of several different types of text processing data in a realistic, natural, and unobtrusive experimental setting. The program allows a sentence-by-sentence presentation of text and allows unconstrained movement forward and backward through the text. Subjects can, at any point during reading, look back at individual sentences presented previously, or review all previously presented sentences at once. All sentence readings and rereadings are timed, and the sequence of readings, rereadings, and reviews is recorded. Following passage reading, questions are asked to examine comprehension and memory of the passage. The program is well suited for the examination of comprehension evaluation and regulation in readers, as well as for the examination of other comprehension and memory processes.     

The on-line processing of written irony

We report an eye-tracking study in which we investigate the on-line processing of written irony. Specifically, participants’ eye movements were recorded while they read sentences which were either intended ironically, or non-ironically, and subsequent text which contained pronominal reference to the ironic (or non-ironic) phrase. Results showed longer reading times for ironic comments compared to a non-ironic baseline, suggesting that additional processing was required in ironic compared to non-ironic conditions. Reading times for subsequent pronominal reference indicated that for ironic materials, both the ironic and literal interpretations of the text were equally accessible during on-line language comprehension. This finding is most in-line with predictions of the graded salience hypothesis, which, in conjunction with the retention hypothesis, states that readers represent both the literal and ironic interpretation of an ironic utterance.     

Teaching Beginning Braille Reading Using an Alphabet or Uncontracted Braille Approach

This study examined the effects of using a research based print reading program modified to accommodate beginning braille readers using an alphabet or uncontracted braille reading approach with five beginning braille readers. Four of the 5 participants displayed a clear increase in their ability to read high frequency words when they began using the Early Steps reading program modified to an Early Steps Alphabet Braille Reading Program. Study findings indicate that access to reading activities and materials afforded to sighted peers resulted in improved reading outcomes for children with visual impairments. Teachers, participants, and family members all viewed the use of the uncontracted braille reading program and materials favorably. Specialized reading instruction was also perceived as beneficial by teachers of students with visual impairments when the training addressed the specific needs of braille readers.     

Parafoveal identification during a fixation in reading.

This paper deals with the extent to which the perceptual span in reading differs as a function of grammatical categories. Subjects read short passages of text and their eye movements were monitored as they did. Irregularities were entered into the text in the subject, verb, or object location of active sentences. Eye movement data were analyzed to determine how far from these various locations the readers were aware of the irregularities. Although there were no differences due to the different parts of speech employed, there was evidence that the perceptual span varied at different locations in text. It was found that readers seldom fixated between sentences and when they did, they were obtaining little information from parafoveal vision.     

Spatial coding in the processing of anaphor by good and poor readers: Evidence from eye movement analyses

An experiment that examined the way in which young readers deployed eye movements while reading sentences and while answering questions containing either a pronominal or noun anaphor is reported. To evaluate the possible causal role played by differences in inspection strategies between readers of above- and below-average reading skill, a third“age control” group of younger children was also tested. This group was matched on absolute reading ability with the less skilled group of older children, and on relative reading ability (i.e. reading quotient) with the more skilled group. Differences in inspection strategy were apparent between the groups of good and poor readers. Good readers launched more selective reinspections, whereas the poorer readers were more inclined to engage in“backtracking” and appeared to make less use of the displayed text. In every case there was a marked similarity in the behaviour of the good readers and the“age controls”. These results suggest that the ability to code the spatial location of words in a sentence, and, where necessary, to use this information to launch accurately targetted selective reinspections of previously read text, plays a crucial role in the development of skilled reading performance.     

The influence of a reading task on children’s eye movements during reading

In the present study, second graders (n= 23), fourth graders (n= 16), sixth graders (n= 24) and adults (n= 21) read texts adopted from children’s science textbooks either with the task to answer a “why” question presented as the title of the text or for comprehension when their eye movements were recorded. Immediately after reading, readers answered a text memory and an integration question. Second graders showed an effect of questions as increased processing during first-pass reading, whereas older readers showed the effect in later look-backs. For adult readers, questions also facilitated first-pass reading. Text memory or integration question-answering was not influenced by the reading task. The results indicate that questions increase the standards of coherence for text information and that already young readers do modify their reading behaviour according to task demands.     

Asymmetries in the perceptual span for Israeli readers

Native Israeli readers read Hebrew and English text as their eye movements were monitored. A window of text moved in synchrony with their eye movements and the window was either symmetrical about the fixation point or offset to the left or right. When subjects were reading Hebrew, the perceptual span was asymmetric to the left and when they were reading English it was asymmetric to the right. The results point out the importance of attentional factors in reading.     

Strategic hand use preferences and hemispheric specialization in tactual reading: impact of the demands of perceptual encoding

Four reading-related, information-processing tasks were administered to right-handed blind readers of braille who differed in level of reading skill and in preference for using the right hand or the left hand when required to read text with just one hand. The tasks were letter identification, same-different matching of letters that differed in tactual similarity, short-term memory for lists of words that varied in tactual and phonological similarity, and paragraph reading with and without a concurrent memory load of digits. The results showed interactions between hand preference and the hand that was actually used to read the stimulus materials, such that left preferrers were significantly faster and more accurate with their left hands than with their right hands whereas right preferrers were slightly but usually not significantly faster with their right hands than with their left hands. In all cases, the absolute magnitude of the left-hand advantage among left preferrers was substantially larger than the right-hand advantage among right preferrers. The results suggest that encoding strategies for dealing with braille are reflected in hand preference and that such strategies operate to modify an underlying but somewhat plastic superiority of the right hemisphere for dealing with the perceptual requirements of tactual reading. These requirements are not the same as those of visual reading, leading to some differences in patterns of hemispheric specialization between readers of braille and readers of print.

中文阅读中快速读者与慢速读者的词频效应

在熟练的中文阅读中,个体阅读效率越高,词汇加工效率是否越高,目前还缺少直接证据。本研究通过记录快速读者与慢速读者在阅读含有高频或低频目标词句子时的眼动轨迹来考察该问题。结果发现,在第一遍注视时间、回视路径时间和总注视时间上,快速读者对高频词与低频词的注视时间无显著差异,但都短于慢速读者;而慢速读者对低频词的注视时间显著长于高频词。即快速读者的早期词汇识别和后期词汇整合效率都较高,不受词频影响;而慢速读者的整个词汇加工效率较低,受词频影响较大。这些结果表明两组读者的词汇加工模式具有本质差异,符合个体差异性观点与词汇质量假说。     

Dyslexia: saccadic eye movements

This paper describes an extensive study of the parameters of saccadic eye movement in a group of 28 poor-reading children and a comparative normally reading group of 31 children. Ages ranged from 6.0 to 16.9 yr. Poor readers had normal intelligence but were lagging by at least two years in reading ability as compared to their peer age group. Parameters studied in refixation eye movements included saccadic latency, accuracy, velocity, and acceleration, as well as differences in latency for abduct and adduct movements. Shapes of saccades were also studied. It was shown that eye-movement performance in simple saccadic refixation was not distinguishably different for poor readers and normal readers, even though in reading, which requires higher processing, eye-movement characteristics are quite different. Maturational changes for various saccadic eye-movement parameters were also examined for the normal and poor reading groups.

Perceptual and task factors in fluent braille

Hypotheses that fluent braille depends (i) on coding letters by global outline shape for all task and speed levels, or (ii) on lateral dot-gap density scanning in fast reading for meaning were tested with three groups of fluent braillists who differed in reading speeds. In experiment 1, 90 degrees-rotated (near to far) texts under vertical and horizontal finger orientation were used. Hypothesis (i) was not supported. Finger orientation interacted significantly with Speed and Task. Vertical finger orientation, which disrupts lateral scanning, slowed reading for comprehension more than for letter search, and differentially more for faster readers. Horizontal finger orientation, which instead disrupts the familiar finger-body relation, did not have differential effects. The findings support hypothesis (ii). In experiment 2, normal texts and texts containing a degraded dot in some letters were used. These are felt in searching for individual letter patterns, but would disrupt lateral scanning of expected dot-gap density patterns in reading for meaning. The results supported the predictions from hypothesis (ii), that degraded texts slow reading for meaning significantly more than for letter search, and more in the case of faster readers than for the slowest group. Findings were not consistent with hypothesis (i), which predicts that text degradation affects tasks equally, and affects the slowest rather than the fastest readers. The results suggest that perceptual coding in reading differs with task demands and speed.

操纵目标词的预测性、词频和阅读技能水平,考察句子阅读中词汇预测性对高、低阅读技能儿童眼动行为的影响,揭示其在儿童阅读发展中的作用。结果显示：儿童对高预测词的跳读率更高、注视时间更短,且预测性与词频交互影响跳读率和注视时间;预测性对高阅读技能儿童早期的跳读率影响更大,而对低阅读技能儿童晚期的再阅读时间具有更大影响。结果表明：词汇预测性影响儿童阅读的眼动行为和词汇加工,且作用大小和发生时程受阅读技能调节。     

空格减少汉语发展性阅读障碍儿童的视觉拥挤效应：来自眼动的证据

使用眼动仪记录汉语发展性阅读障碍儿童、正常年龄匹配和能力匹配儿童阅读插入空格文本时的眼动,考察在字、词以及非词间插入空格呈现文本对汉语发展性阅读障碍儿童阅读加工过程的影响。结果发现,阅读障碍儿童在字间空格条件下平均注视时间减少的程度大于正常儿童,注视次数在字间和词间空格条件下未见显著增加,能力匹配儿童的注视次数在这两种空格条件下却显著增加。结果说明,在字间和词间插入空格能够减少儿童的平均阅读时间,且字间空格文本呈现显著地提高了其阅读效率,说明空格对汉语阅读障碍儿童具有促进作用,这种促进主要是由于空格减少了其视觉拥挤效应所致。
