An eye movement analysis of topic-shift effect during repeated reading.

This study replicated previous reading time studies that have observed increased reading times for sentences introducing a new subtopic in a text, compared with sentences that are continuations of a subtopic. This topic-shift effect was obtained for the initial reading but not when the same text was reread. The absence of topic-shift effect was taken to suggest that readers construct a mental representation of the text's topic structure during the initial reading. The topic-shift effect was primarily due to regressive fixations, which tended to land in the first half of sentences. Regressions were typically launched at the end of sentences, with topic-shift sentences also well before the sentence end was reached. These findings are interpreted as evidence for the integrative nature of regressive fixations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eye movement efficiency in normal and reading disabled elementary school children: effects of varying luminance and wavelength

BACKGROUND: This investigation examines the question of whether decreasing wavelength of light and/or reducing luminance benefits oculomotor efficiency in normal and reading disabled (RD) children. METHODS: Two groups of children were identified as normal or disabled readers using standardized reading tests. After suitable practice, eye movements were objectively measured with the Visagraph II as each of the subjects silently read a series of three different selections at their independent reading level with clear (control), gray, and blue filters. Four variables were measured for each subject. Data were analyzed using a repeated measure ANOVA and post hoc tests. RESULTS: The standardized reading tests significantly differentiated average from poor readers using grade scores and percentiles. Initially, with clear filters, eye movement scores of normal readers were superior to disabled readers for fixations regressions, and rate of reading. Among the RDs--but not the normals--the three variables improved with the blue filter when compared with the clear filter, number of fixations and regressions were significantly lower, and rate was significantly higher. Gray filters yielded no significant changes. Improvement with the blue filters normalized the three variables in that there were no significant differences between normal and disabled readers. CONCLUSION: This investigation confirms a link between wavelength of light and eye movement efficiency in reading. Blue filters resulted in a significant improvement in the number of fixations and regressions and rate of reading in RD children. The outcome broadens the concept of transient system deficit established in previous research to include the effect on oculomotor efficiency. The educational implications of this study are of special interest to optometrists.     

Strategic processing during comprehension.

This study addresses 3 questions: How flexible are readers when reading strategically? How is strategic processing affected by properties of the text? and Do some strategies lead to better text retention than others? Participants read short narratives and thought aloud with an instruction to either explain, predict, associate, or understand. The think-aloud protocols were used to predict sentence reading times for other participants who read silently with the same strategies. The results indicated that readers are capable of strategically controlling the inferences that they generate. However, strategic control comes at some cost in that it limits the resources devoted to other inferences. Furthermore, strategic processing is heavily constrained by a text. Text-based explanations occurred when there was an identifiable causal antecedent in the prior text. Knowledge-based inferences occurred when there were no antecedents and when new characters and objects were introduced. These effects occurred across reading strategies. Reading to explain led to better memory, but only when reading silently. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Resilient readers? University students who are poor recoders but sometimes good text comprehenders.

The authors screened 194 university students to determine whether some could comprehend text well despite very poor recoding skills, measured by pseudoword reading. Most of the 17 poorest recoders had never been identified as reading disabled. We classified 6 poor recoders as "resilient readers" because their text comprehension scores were average or above, relative to the sample as a whole. They were indistinguishable from 6 matched typical readers on measures of text comprehension derived from oral-reading think-aloud protocols. There was no evidence that the resilient readers relied on superior verbal ability or working memory to compensate for poor recoding. The resilient readers were poor at spelling, reading isolated words, and reading text rapidly, but they showed adequate phonemic awareness.

A theory of reading: From eye fixations to comprehension.

Presents a model of reading comprehension that accounts for the allocation of eye fixations of 14 college students reading scientific passages. The model deals with processing at the level of words, clauses, and text units. Readers made longer pauses at points where processing loads were greater. Greater loads occurred while readers were accessing infrequent words, integrating information from important clauses, and making inferences at the ends of sentences. The model accounts for the gaze duration on each word of text as a function of the involvement of the various levels of processing. The model is embedded in a theoretical framework capable of accommodating the flexibility of reading. (70 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Encoder: A Connectionist Model of How Learning to Visually Encode Fixated Text Images Improves Reading Fluency.

This article proposes that visual encoding learning improves reading fluency by widening the span over which letters are recognized from a fixated text image so that fewer fixations are needed to cover a text line. Encoder is a connectionist model that learns to convert images like the fixated text images human readers encode into the corresponding letter sequences. The computational theory of classification learning predicts that fixated text-image size makes this learning difficult but that reducing image variability and biasing learning should help. Encoder confirms these predictions. It fails to learn as image size increases but achieves humanlike visual encoding accuracy when image variability is reduced by regularities in fixation positions and letter sequences and when learning is biased to discover mapping functions based on the sequential, componential structure of text. After training, Encoder exhibits many humanlike text familiarity effects. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Differential effects of higher and lower order questions: Attention hypotheses.

Five experiments were performed with 166 undergraduate students to determine whether (a) different amounts of attention are demanded of readers during the reading of relevant segments of text prefaced by higher and lower order questions; (b) different amounts of attention are demanded of readers by higher and lower order questions following relevant segments of text, and if so, if inattention varies during the reading of text, during the reading and answering of the postquestions, or at both times; and (c) different amounts of attention are required of readers during the reading of prefatory higher and lower order questions. Findings indicate that the reaction times (RTs) of Ss to auditory probes were significantly longer during the reading of paragraphs following higher order questions than they were during the reading of paragraphs following lower order questions. When auditory probes were presented during the reading of prequestions themselves, no significant difference in RTs was observed between higher and lower order questions.

The effects of reading purpose and working memory capacity on the processing of expository text.

The extent to which low- and high-WMC (working memory capacity) readers adjust cognitive processes to fit the reading purpose was examined. Participants performed a verbal protocol task as they read an expository text under 1 of 2 reading purpose conditions, entertainment or study, and then completed a free-recall task. When reading to study, low-WMC readers emphasized less demanding processes over more demanding processes to a greater extent than high-WMC readers and recalled less. When reading for entertainment, patterns of processes and recall were similar across readers. Thus, all readers adjusted processing to fit the reading purpose; however, when reading for study, low-WMC readers emphasized processes that were the least demanding on their resources but not necessarily beneficial for recall.

An instructional study: Improving the inferential comprehension of good and poor fourth-grade readers.

Four classroom teachers provided instruction to improve the inferential comprehension of 40 good and poor 4th-grade readers, as determined by scores on the Stanford Achievement Test. The experimental treatment consisted of 3 parts: (a) making students aware of the importance of drawing inferences between new information and existing knowledge structures; (b) getting students to discuss, prior to reading, something they had done that was similar to the events in the text and to hypothesize what would happen in the text; and (c) providing students with many inferential questions to discuss after reading the selection. Results show that poor readers benefited significantly from the instruction, but good readers did not. This differential effect was attributed to the dissimilar aptitudes of good and poor readers and the dissimilar instructional methods that are used with good and poor readers in schools. Conclusions focus on the positive prospect of modeling successful instructional procedures on theoretical, basic research. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reading both high-coherence and low-coherence texts: Effects of text sequence and prior knowledge.

Determined if (1) the advantage for the low-coherence text is due to inferences made while reading, or alternatively, due to inferences generated during testing as a result of less information being available from the low-coherence text; (2) the inferences must rely on prior knowledge, or if inferences based on the text (or recently presented information) are sufficient; and (3) reading 2 different text versions is advantageous for readers. Ss were 80 university students who were assigned to 1 of 4 conditions representing if the Ss read the high-coherence text followed by either the high- or low-coherence text, or the low-coherence text followed by either the high-or the low-coherence text. Methodology involved reading the texts, answering questions about the text, and answering prior knowledge questions. The results indicate that high-knowledge readers benefited from the low-coherence only text when it was read first. Further, low-knowledge readers benefited from the high-coherence text, regardless of whether it was read first, second, or twice. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eye fixation patterns among dyslexic and normal readers: Effects of word length and word frequency.

Eye fixation patterns of 21 dyslexic and 21 younger nondyslexic readers were compared when they read aloud 2 texts. The study examined whether word-frequency and word-length effects previously found for skilled adult readers would generalize equally to younger dyslexic and nondyslexic readers. Significantly longer gaze durations and reinspection times were found for low-frequency and long words than for high-frequency and short words. The effects also showed up in the number of fixations on the target words. The effects did not differ significantly for the 2 experimental groups. The results run counter to the oculomotor dysfunction hypothesis of dyslexia. Instead, they support the view that both dyslexic and nondyslexic readers' eye fixation patterns reflect their difficulties in successfully identifying words in a text.

Word learning in predictable text.

Predictable text has become widely used for beginning readers but has not been the subject of much research. This study used predictable books to compare 3 reading treatments reflecting different components of a whole-to-part instructional model. In 3 first-grade classrooms, beginning readers working with isolated words in a modified word bank activity learned more words than when they worked with sentence strips. They also learned more words using sentence strips than when they simply read and reread the books. There was a significant treatment effect, justifying the theoretical position that beginning readers learn more words when those words are removed from the supportive context offered by predictable text. Students with higher levels of literacy skill learned 5 times as many words as those with lower levels. The overall number of words learned in these predictable books appears limited. These findings have important implications for the use of texts in beginning reading programs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evaluation of purposeful reading skills in elementary-age students.

In a computer-controlled reading task, more and less able fourth-grade readers identified text segments containing question-relevant information and then attempted to answer assigned questions. Better readers were found to be more adept at locating critical information and at answering the questions. Whereas the better readers responded to assigned questions with a higher degree of accuracy when they were aware of the location of text relevant to the question, less able readers seemed unable to benefit in situations in which they were able to locate the relevant information. Although the ability to locate goal-relevant information was found to be important, readers also had to be able to process the important ideas as demanded by the goals to be accomplished.

Depending on my mood: Mood-driven influences on text comprehension.

Reading comprehension is a critical component of success in educational settings. To date, research on text processing in educational and cognitive psychological domains has focused predominantly on cognitive influences on comprehension and, in particular, those influences that might be derived from particular tasks or strategies. However, there is growing interest in documenting the influences of emotional factors on the processes and products of text comprehension, because these factors are less likely to be associated with explicit reading strategies. The present study examines this issue by evaluating the degree to which mood can influence readers' processing of text. Participants in control, happy-induced, or sad-induced groups thought aloud while reading expository texts. Happy, sad, and neutral moods influenced the degree to which readers engaged in particular types of coherence-building processes in the service of comprehension. Although reading strategies clearly influence processing, understudied factors that are less explicitly goal-driven, such as mood, can similarly impact comprehension activity. These findings have important implications for the role of mood on reading instruction and evaluation. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Are general resource notions still viable in reading research?

Conducted 2 experiments to explore the interplay between reading subcomponent efficiency and comprehension processes in terms of resource competition. In Exp 1, adults were tested on the efficiency of lexical access, semantic memory access, verbal working memory span, contextual priming, and the efficiency with which anaphors are resolved. The profile was used to predict the efficiency of high-level inference generation when readers control the pace of reading. In Exp 2, this profile was used to predict the efficiency of high-level inferencing as text was presented at a preset rate. The data suggest that when readers control reading rate, they compensate for subcomponent inefficiency such that high-level comprehension is unrelated to this inefficiency. However, when they must follow along, those who possess more efficient reading subcomponents make high-level inferences more efficiently.

Reading skill as a source of individual differences in the processing of instructional texts.

Evidence was found in support of the hypothesis that skilled readers are more likely than less skilled readers to successfully retrieve an appropriate procedure by reading an instructional text. Subjects completed a standardized reading comprehension test and a test designed to reflect their processing of an instructional text and an example. The instructional text and the example either described the same procedure for answering test items (no conflict) or described different and mutually exclusive procedures (conflict). Subjects who had higher scores on the reading test were more likely to notice the conflict between the instructional text and the example, and those who noticed the conflict were more likely to use the instructional text.

Reading strategies for children and adults: A quantitative model.

Developed an additive model to account for reading times for 2 different reading tasks (reading for retention and reading for comprehension). The reading strategies of 48 college students and 64 5th graders and individual differences between fast and slow readers were examined. Ss were assumed to have processors that handle the lexical, structural, and meaning information in sentences. The various task, age, and reading speed groups were hypothesized to use the 3 processors for differing amounts of time. The model was supported by word-by-word reading times for 80 sentences and by 9 empirical indices of lexical, structural, and meaning attributes of text. Results show that for skilled adult Ss, relatively more time was spent processing structure in the retention task, and meaning in the comprehension task. Fifth graders had not fully mastered the connection between task demands and linguistic processors shown by adults, and thus used mixtures of the adult strategies.

Visuospatial cues for reinstating mental models in working memory during interrupted reading.

Reading involves constructing a mental representation in long-term working memory of the world described by the text. Disrupting short-term working memory can interfere with the maintenance of mental models (sets of retrieval cues) needed to access these representations, producing detrimental effects on reading time. In two experiments, subjects read passages that included pairs of coreferential sentences interrupted by unrelated text. As in previous research, reading times increased for the first sentence after the interruption, likely reflecting a reinstatement process for mental models in working memory. In the present research, pictures were provided as visuospatial cues to aid the reinstatement process. The interruption effect was found to be smaller with pictures related to the passages than with unrelated pictures (Experiment 1) or titles (Experiment 2); however, both of these effects occurred only for slow readers. The authors hypothesize that slow readers take the time needed to integrate visuospatial information into their mental models, providing more resilient access to long-term working memory.
