Working memory and updating processes in reading comprehension

In this study, we examine the relation between reading comprehension ability and success in working memory updating tasks. Groups of poor and good comprehenders, matched for logical reasoning ability, but different in reading comprehension ability, were administered various updating tasks in a series of experiments. In the first experiment, the participants were presented with lists of words, the length of which (4-10 words) was unknown beforehand, and were required to remember the last 4 words in each series. In this task, we found a decrease in performance that was related to longer series and poor reading ability. In the second experiment, we presented lists of nouns referring to items of different sizes, in a task that simulated the selection and updating of relevant information that occurs in the on-line comprehension process. The participants were required to remember a limited, predefined number of the smallest items presented. We found that poor comprehenders not only had a poorer memory, but also made a greater number of intrusion errors. In the third and fourth experiments, memory load (number of items to be selected) and suppression request (number of potentially relevant items) were manipulated within subjects. Increases in both memory load and suppression requests impaired performance. Furthermore, we found that poor comprehenders produced a greater number of intrusion errors, particularly when the suppression request was increased. Finally, in a fifth experiment, a request to specify the size of presented items was introduced. Poor comprehenders were able to select the appropriate items, although their recall was poorer. Altogether, the data show that working memory abilities, based on selecting and updating relevant information and avoiding intrusion errors, are related to reading comprehension.     

Fundamental factors of comprehension in reading

A survey of the literature was made to determine the skills involved in reading comprehension that are deemed most important by authorities. Multiple-choice test items were constructed to measure each of nine skills thus identified as basic. The intercorrelations of the nine skill scores were factored, each skill being weighted in the initial matrix roughly in proportion to its importance in reading comprehension, as judged by authorities. The principal components were rather readily interpretable in terms of the initial variables. Individual scores in components I and II are sufficiently reliable to warrant their use for practical purposes, and useful measures of other components could be provided by constructing the required number of additional items. The results also indicate need for workbooks to aid in improving students' use of basic reading skills. The study provides more detailed information regarding the skills measured by theCooperative Reading Comprehension Tests than has heretofore been provided regarding the skills actually measured by any other widely used reading test. Statistical techniques for estimating the reliability coefficients of individual scores in principal-axes components, for determining whether component variances are greater than would be yielded by chance, and for calculating the significance of the differences between successive component variances are illustrated.On leave for military service.     

Phonemic effects in reading comprehension and text memory

Two experiments investigated the role of phonemic information in adult reading comprehension and replicated the visual tongue-twister effect in a new paradigm–a modified probe memory task. College students took longer to read sentences that repeated word initial consonants (tongue-twisters) than matched control sentences. Equally important, subjects also took longer to respond to probe words from tongue-twisters. Slower response times in both the sentence reading task and the probe memory task indicate that the tongue-twister effect is indeed phonemic in nature and that phonemic information is used in memory during comprehension.     

Modification of deficits in reading for comprehension

Subjects were asked to read a passage orally and then to answer questions about the passage. When praise and pennies were given for correct answers, the percentage of correct answers increased in two sixth-grade subjects whose reading for comprehension was tested to be 2 yr below grade level. The behavior of these subjects was compared to that of two subjects whose reading for comprehension was tested to be on grade level. Although no evidence for changes in the accuracy of answering comprehension questions is found in the previous literature, the percentage of correct answers in the children with deficits increased to approximately the same level as the children tested to be on grade level.

Contextual effects on metaphor comprehension in reading

Subjects read target sentences preceded by either short or long context that induced either a metaphoric or a literal target reading. As had been found by Ortony, Schallert, Reynolds, and Antos (1978), metaphoric targets were comprehended about as quickly as literals when context was long, but more slowly than literals when context was short. The latter result may have been due to the failure of computing a conceptual relationship between short context and metaphoric target; targets unrelated to prior context took as long to comprehend as metaphoric targets. Another experiment showed that metaphorically expressed targets were read more quickly when they followed metaphorically expressed context than when they followed literal context, but literal targets were read quickest when they followed literal context. These results are discussed within a schema framework and within a “process priming” hypothesis.     

The effects of prior knowledge and text structure on comprehension processes during reading of scientific texts

The aim of the present study was to investigate the effects of prior knowledge and text structure on cognitive processes during comprehension of scientific texts. To investigate the processes online, we used a think-aloud methodology in Experiment 1 and a reading time methodology in Experiment 2. In both experiments, we obtained offline comprehension measures and measures of individual differences in working memory and need for cognition. Across the two experiments, the results indicated that readers adjust their processing as a function of the interaction between prior knowledge and text structure. In particular, adjustments in theactual processes that take place during reading were observed for readers who had erroneous prior knowledge,but only when they read a text that was structured to explicitly refute this prior knowledge. Furthermore, the results showed that readers' memory for the text was affected by differences in their prior knowledge, independently of text structure. These findings contribute to our understanding of the relation between different factorsthat are associated with comprehension of scientific texts and have implications for theories of comprehension and conceptual change.     

The relation between children's reading comprehension level and their comprehension of idioms

We report an investigation of 9-year-olds' ability to interpret idioms in relation to their reading comprehension level. We manipulated whether the idioms were transparent or opaque, whether they were real or novel, whether they were presented in isolation or in a supportive narrative context. As predicted, children were better able to explain the meanings of idioms in context than in isolation. The good and poor comprehenders did not differ in their abilities to interpret transparent idioms in context, but the poor comprehenders were significantly worse at using context to work out the meanings of opaque idioms. The explanation task revealed the source of information used by the children to derive nontarget interpretations. We discuss these findings in relation to idiom processing strategies and Levorato and Cacciari's global elaboration model.     

Peripheral vision training in reading speed and comprehension.

Of two groups of 8 college students receiving 15.75 hr. of speed reading training, an experimental group was given an additional 2.25 hr. of peripheral vision training. Peripheral vision increased for both groups, but reading speed improved only in the trained group. Reading comprehension scores were not affected.     

Interactive processes in sentence comprehension and recognition

Two experiments examined the roles played by semantic and surface information in reading and recognizing sentences. Subjects read sentences in normal and inverted typography. Their recognition of meaning and other sentence features was tested using sentences whose typography, wording, and/or meaning were either the same as or different from that in the first set of sentences. In Experiment 1, subjects either read aloud or performed a sentence continuation task. For originally inverted sentences, recognition of meaning was high, irrespective of task demands. For originally normal sentences, recognition was low for Read Aloud subjects and high for Sentence Continuation subjects. Sentence recognition was affected by repetition of wording and typography. Experiment 2 replicated the results with the read aloud task and showed the second reading of originally inverted sentences to be equally swift for paraphrase and verbatim test forms. It was concluded that reading and recognition are interactive processes, involving conceptually driven and data driven operations. The interaction of operations may be either automatic or controlled. While processing of normal typography is automatic, inverted typography induces controlled processing, resulting in better retention. Furthermore, semantic and surface information are conceptualized as interacting components of comprehension and memory processes.     

Contextual influences in reading comprehension in aphasia.

Aphasic subjects' auditory comprehension of reversible passive sentences is facilitated by preceding predictive and nonpredictive narratives (Hough, Pierce, & Cannito, 1989, Brain and Language, 36, 325-334). The present study found that aphasic subjects also comprehended written reversible passive sentences significantly more accurately when they were preceded by either predictive or nonpredictive five-sentence narratives than when they were presented in isolation. Also tested was the contention that predictive narratives do not improve aphasic subjects' ability to process target sentences but simply allow these sentences to be ignored. This contention was not supported. The aphasic subjects did not comprehend predictive narratives presented without the subsequent target sentences more accurately than they comprehended the target sentences presented in isolation. For comprehension to be enhanced, both the contextual narratives and the target sentences must be present.     

The role of assembled phonology in reading comprehension

The contribution of assembled phonology to phonological effects in reading comprehension was assessed. In Experiment 1, subjects judged the acceptability of sentences with regular, exception, and nonword homophone substitutions and orthographic controls. Significantly more errors occurred to sentences with regular-word homophones than to exception words, and error rates for nonword homophones were low and not significant. Experiment 2 showed that this was not due to differences in the sentence frames. In Experiment 3, the subjects judged as unacceptable those sentences containing an exception word that sounded correct when read according to spelling-to-sound rules. Significantly higher error rates occurred only for low-frequency exception words. Experiment 4 showed that task conditions affect semantic-categorization error rates for nonword homophones. These results indicate that both assembled and addressed phonology contribute to sentence and word comprehension, but the low error rate for nonwords suggests that an early lexical check may be applied.     

Uncertainty reduction in different languages through reading comprehension

In an exploratory study into the feasibility of constructing a multilingual reading comprehension test, parallel cloze tests were constructed in Czech, English, French, German, and Polish. Groups of children between the ages of eight and fourteen were tested on the version in their own mother tongue, in Prague (Czechoslovakia), in Saskatoon and Prince Albert (Canada), and in Paris (France), Frankfurt (Germany), and Warsaw (Poland). Test performance was assessed by means of a method which estimates the child's contribution to overall language redundancy. Results suggest that the method is both reliable and valid and has potential for the assessment of bilinguality of reading comprehension.     

False recollection in children with reading comprehension difficulties

Children with reading comprehension difficulties display impaired performance on semantic processing tasks. These impairments are assumed to reflect weaker knowledge about abstract semantic associations between words in poor comprehenders [Nation, K., and Snowling, M. (1999). Developmental differences in sensitivity to semantic relations among good and poor comprehenders: evidence from semantic priming. Cognition, 19, B1-B13.]. We examined the performance of poor comprehenders on the Deese/Roediger/McDermott (DRM) paradigm. Children studied spoken words that were semantic associates (e.g., bed, rest, and awake) or phonological associates (e.g., pole, bowl, and hole) followed by free recall and a recognition test containing nonstudied critical words (e.g., sleep and roll). Results showed reduced recall and recognition of critical words in the semantic condition but not in the phonological condition for poor comprehenders. We argue that poor comprehenders are less sensitive to abstract semantic associations between words because of reduced gist memory.     

Working-memory capacity and reading comprehension in young and older adults

Summary This study investigates the role of working-memory capacity in reading comprehension in young and older subjects. A task yielding separate measures for processing and storage components was used to assess working-memory capacity. A French version of the Nelson-Denny test was administered as a measure of abilities that underlie reading comprehension. In the working-memory task, recall performances were lower in older subjects. Nevertheless, the intercorrelations suggested that the age-related impairment was probably linked to the processing component. Mean scores on the reading-comprehension test did not differ between groups. However, scores were correlated with processing time on the working-memory task in younger subjects, but with storage capacity in older subjects.     

The utility and accuracy of oral reading fluency score types in predicting reading comprehension

This study used data from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS; Good & Kaminski, 2002) oral reading fluency (ORF) probes to examine variation among different ORF score types (i.e., the median of three passages, the mean of all three passages, the mean of passages 2 and 3, and the score from passage 3) in predicting reading comprehension as a function of student reading fluency level and to compare the screening accuracy of these score types in predicting student reading comprehension. The results revealed that the relation between oral reading fluency and reading comprehension varied as a function of students' oral reading fluency and that different score types had varying predictive validity for year-end reading comprehension. The mean of all three passages demonstrated a marginally better balance in screening efficiency from September to December of grade one (especially for low-performing students), whereas in grades two and three, the median score was the best predictor. Furthermore, across all grades, increasing reading rates were observed for the three administered passages within an assessment period. The observed patterns mimicked previous experimental studies (Francis et al., 2008; Jenkins, Graff, & Miglioretti, 2009), suggesting that practice effects are an important consideration in the administration of multiple passages assessing oral reading fluency.     

Fostering reading comprehension in fifth grade by explicit instruction in reading strategies and peer tutoring

Background: Research reveals that explicit reading strategies instruction and engaging students in interaction about texts promote students' reading comprehension ability. The present intervention study combines both aspects. Aims: The study examines the educational benefits of explicit reading strategies instruction, followed by practice in (a) teacher‐led whole‐class activities (STRAT), (b) reciprocal same‐age (STRAT + SA), or (c) cross‐age peer tutoring activities (STRAT + CA) on fifth graders' reading comprehension achievement. Sample: Twenty‐two fifth‐grade teachers and their 454 students from 19 different schools throughout Flanders (Belgium) participated. Method: A quasi‐experimental pretest post‐test retention test design was used with three experimental (STRAT, STRAT + SA, and STRAT + CA) and a matched control group. The experimental interventions were implemented during an entire school year. Results: Multilevel analysis revealed that the STRAT and STRAT + CA condition made a significantly larger pretest to retention test progress than the control group. The significant major progress was especially situated from pretest to post‐test, during which the intervention took place. Concerning the STRAT + SA condition no significant differences with regard to the control group were detected. Pairwise comparisons of the experimental conditions indicated that the STRAT + CA condition's progress from pretest to retention test also exceeded the STRAT + SA condition's advancement significantly. Conclusion: The study corroborated the efficacy of the STRAT and STRAT + CA conditions' interventions as feasible tools to enhance fifth graders' reading comprehension achievement.
