Low accuracy levels are often obtained when readers are asked to predict test performance over reading materials. Three investigations further explore the information readers use to make predictions during metacomprehension. Our results show that readers’ estimates are influenced by factors such as their initial impression of the reading task, based in part on their perceptions surrounding text genre and test item type. To explain these and other published results, a new framework for investigating metacomprehension using Tversky and Kahneman’s (Science, 185:1124–1131, 1974) anchoring and adjustment heuristic as a guide is proposed. We argue that readers anchor comprehension test performance on factors such as self-perceptions of reading ability and/or perceptions of the reading task and then insufficiently adjust their predictions to reflect the demands of the specific reading task at hand such as text difficulty.  相似文献

The ability to monitor the status of one’s own understanding is important to accomplish academic tasks proficiently. Previous studies have shown that comprehension monitoring (metacomprehension accuracy) is generally poor, but improves when readers engage in activities that access valid cues reflecting their situation model (activities such as concept mapping or self-explaining). However, the question still remains as to which process, encoding or retrieving, causes the improvement of metacomprehension accuracy, and the findings of previous research on this matter have been inconsistent. This study examined whether college students’ metacomprehension accuracy improves when they expect, at the time of reading, that they will explain the content later (active encoding) or when they actually generate an explanation (encoding plus active retrieving). In the experiments, college students read five texts. During reading, some students expected that they would generate explanations but did not actually generate them. In contrast, some students actually generated an explanation of the text after reading. All students then rated their comprehension of each text. Finally, they completed tests on the materials. Results of both studies revealed that metacomprehension accuracy, operationalized as the association between comprehension ratings and test performance, was greater for the group that actually generated explanations than for the expectancy or control groups.  相似文献

The aim of this study was to investigate the theory that visual magnocellular deficits seen in groups with dyslexia are linked to reading via the mechanisms of visual attention. Visual attention was measured with a serial search task and magnocellular function with a coherent motion task. A large group of children with dyslexia (n = 70) had slower serial search times than a control group of typical readers. However, the effect size was small (η p2 = 0.05) indicating considerable overlap between the groups. When the dyslexia sample was split into those with or without a magnocellular deficit, there was no difference in visual search reaction time between either group and controls. The data suggest that magnocellular sensitivity and visual spatial attention weaknesses are independent of one another. They also provide more evidence of heterogeneity in response to psychophysical tasks in groups with dyslexia. Alternative explanations for poor performance on visual attention tasks are proposed along with avenues for future research.  相似文献

Despite an extensive literature linking individual differences in phonological processing to reading ability, some adults show normal text comprehension abilities despite poor pseudoword reading (Jackson & Doellinger (2002). Journal of Educational Psychology, 94, 64–78). This study was undertaken to investigate differences between these individuals, termed resilient readers, and proficient readers in performance and degree of lateralization on a variety of single word processing tasks. Participants completed seven divided visual field tasks investigating various aspects of reading. Resilient readers performed less accurately on basic word recognition tasks, but not on the tasks involving semantic access. Resilient readers did not differ from proficient readers on reaction time or lateralization on any of the experimental tasks. These findings are consistent with the hypothesis that skilled phonological decoding is not necessary for reading for meaning in a college population. It is proposed that higher-level semantic information and general world knowledge may allow some readers to compensate for deficiencies in lower-level word recognition processes.

Although weaknesses in metaphonological skills are well-documented in poor readers, prior studies have yielded inconsistent findings as to whether less-skilled readers also have deficits in the more primary phonological processes entailed in verbal working memory and speech production tasks. The present study was designed to examine this issue by comparing less-skilled third-graders readers (n=30) with younger children at the same reading level (n=30) and with more-skilled agemates (n=30) on a variety of tasks that require phonological processing (i.e., three “verbal memory” tasks [word span, span with concurrent processing, pseudoword imitation] and three “speech production” tasks [word-pair repetition, tongue twisters, rapid naming]). The results were striking: the less-skilled third-grade readers had significantly lower accuracy scores than both their agemates and the younger normal readers on the word span, pseudoword imitation, word-pair repetition, and tongue twister tasks. Measures of accuracy were more related to reading ability than were measures of speed. Performance on a pseudoword imitation task was the variable most strongly linked to reading achievement.  相似文献

The objective of this paper is to review and synthesize two interrelated topics in the adult metacomprehension literature: the bases of metacomprehension judgment and the constraints on metacomprehension accuracy. Our review shows that adult readers base their metacomprehension judgments on different types of information, including experiences with current tasks and pre-formed expectations of performance affected by factors such as self-perception of ability. We propose a model that shows the anchoring and adjustment mechanism (Tversky and Kahneman, Science 185:1124–1130, 1974) underlies metacomprehension judgments. Specifically, due to test uncertainty, people may judge future comprehension performance by starting with an anchor such as pre-formed performance expectations and then (insufficiently) adjust away from it based on experiences with current tasks. This anchoring and adjustment model of metacomprehension judgment sheds light on what constrains metacomprehension accuracy. We conclude that two main accuracy constraints are the anchoring effect and the poor diagnostic validity of experiential cues. Based on the review, we discuss avenues for future research that will further our understanding of the mechanisms underlying metacomprehension.  相似文献

The authors investigated differences in the processes underlying two types of metacomprehension judgments: judgments of difficulty and predictions of performance (JOD vs. POP). An experiment was conducted to assess whether these two types of judgments aligned with different types of processing cues, and whether their accuracy correlated with different factors such as sensitivity to processing ease and reading ability. Participants (n?=?72) read an extended text about brain structure and after each sentence made either a JOD or POP. Results suggested that JODs and POPs were made based on different sets of cues because different factors correlated with the accuracy of metacomprehension judgments. JOD accuracy correlated with sensitivity to processing ease and POP accuracy most strongly correlated with reading ability. Engaging in different metacomprehension judgments during reading may alter the information sources to which a reader attends and which factors influence metacognitive accuracy.  相似文献

The present research examined the effect of illustrations on readers' metacomprehension accuracy for expository science text. In two experiments, students read non-illustrated texts, or the same texts illustrated with either conceptual or decorative images; were asked to judge how well they understood each text; and then took tests for each topic. Metacomprehension accuracy was computed as the intra-individual correlation between judgments and inference test performance. Results from both studies showed that the presence of decorative images can lead to poor metacomprehension accuracy. In the second study, an analysis of the cues that students reported using to make their judgments revealed that students who used comprehension-relevant cues showed more accurate metacomprehension. A self-explanation instruction did not alter either comprehension-relevant cue use or metacomprehension accuracy, although some advantages were seen when readers were prompted to self-explain from texts illustrated with conceptual images. These results suggest that students may need more explicit instruction or support to promote the use of valid cues when engaging in comprehension monitoring with illustrated text, and that seductive information such as decorative images may undermine comprehension monitoring.  相似文献

This paper examines evaluation in reading. Evaluation refers to the processes by which readers monitor their ongoing text comprehension to assess performance and task difficulties. Monitoring is assumed to explain a large proportion of individual differences in text comprehension, in that individuals need to be aware of their objectives and difficulties in order to adjust their strategies to match task requirements. The participants were French children in grades 3 and 5. Study 1 examined their evaluation-related knowledge (i.e., knowledge about reading objectives, sources of difficulties, comprehension awareness). Study 2 examined the children’s actual evaluation behavior during a comprehension task. The results showed that few children provided elaborate verbalizable knowledge about reading tasks, goals and corresponding skills, and that in most cases the children were highly confident in their responses to text comprehension questions, regardless of the correctness of their answer. The contribution of metalinguistic awareness to literacy acquisition as well as the implications of this type of study for educational practice are discussed.  相似文献

We examined the nature of and factors related to adolescents’ reading difficulties in a highly transparent orthography. We compared word, pseudoword, and text reading speed and accuracy, rapid naming (RAN) and phonological processing between poor readers (n?=?80) and normally developing readers (n?=?189). Reading problems were manifested in reading speed and in timed pseudoword reading accuracy. RAN predicted speed, and phonological processing predicted accuracy of reading in both groups. Among poor readers, RAN also explained reading accuracy. For the normally developing sample, phonological processing also predicted reading speed.  相似文献

The primary aim of the current study was to identify the strongest independent predictors of reading comprehension using word reading, language and memory variables in a normal sample of 180 children in grades 3–5, with a range of word reading skills. It was hypothesized that orthographic processing, receptive vocabulary and verbal working memory would all make independent contributions to reading comprehension. The contributions of reading speed, receptive grammatical skills, exposure to print, visuospatial working memory and verbal learning and retrieval (a measure of longer-term retention) were also investigated. Working memory tasks that required the processing and storage of numerical and spatial material were used. One of the numerical working memory tasks was based on the number span task developed by Yuill, Oakhill, and Parkin British Journal of Psychology, 1989, 80, 351–361. A visuospatial equivalent of that task was developed from the forward Corsi block task [Corsi, Abstracts International, 1973, 34, 891]. The results revealed that, after controlling for age and general intellectual ability, the word reading and the language variables had a much stronger relation with reading comprehension than the memory variables. The strongest independent predictor of reading comprehension was orthographic processing since it captured variance in both word reading, language skills and verbal working memory. The forward Corsi task and performance on a measure of verbal learning and retrieval each made small independent contributions to reading comprehension but the contribution of verbal working memory was not significant. It was concluded that tasks measuring the interplay between short-term and long-term memory, in which new information is combined with information already stored in long-term memory, may better predict reading comprehension measured with the text available than working memory tasks which only have a short-term memory component.  相似文献

Background

This study was designed to extend our understanding of phonology and reading to include suprasegmental awareness using measures of prosodic awareness, which are complex tasks that tap into the rhythmic aspects of phonology. By requiring participants to access, reflect on and manipulate word stress, the prosodic awareness measures used here necessarily impose demands on the executive system. Prosodic awareness was evaluated as a phonological predictor of reading in older readers while controlling for executive functions (EF) in order to ascertain whether observed predictive relationships could be confidently attributed to suprasegmental awareness.

Methods

103 adults between 18 and 55 years of age completed tasks on prosodic awareness, EF, vocabulary, nonverbal abilities, naming speed and short‐term memory.

Results

Independent contributions of prosodic awareness added to models of word reading, whereas EF processes did not uniquely contribute to adult reading outcomes.

Conclusions

Suprasegmental phonology explains individual differences in word reading among experienced readers. Theoretical implications of findings are discussed.

Implications for Practice

What is already known about this topic
  • Phonological awareness (PA) becomes less predictive of reading in older readers. PA is typically assessed at the level of the segment (e.g., phonemes, syllables and onset‐rimes), with less focus on suprasegmental processes (e.g., rhythm, stress and intonation).
  • Suprasegmental phonological processing includes measures of prosodic ability (e.g., awareness and manipulation of suprasegmental features of oral language). Studies on prosodic awareness and reading have independent contributions beyond segmental PA in early readers. Less work has been investigated among adult readers.
  • Executive functions (EF) including inhibitory control, working memory, switching and updating and monitoring of goal directed behaviour, predict overall academic achievement. Limited studies have controlled for EF demands in phonological tasks.
What this paper adds
  • Tasks of prosodic awareness necessarily impose demands on the executive system when manipulating components of oral language. After controlling for EF and controls, prosodic awareness explained individual differences in adult word reading.
  • Tasks of suprasegmental phonological processes explain the association between phonology and reading in older and more experienced readers. Researchers who explore phonology and reading development should begin to include tasks of prosodic awareness to examine the dual role of segmental and suprasegmental PA as it is implicated across development.
Implications for theory, policy or practice
  • Theoretical models of phonology and reading can be extended to include suprasegmental processes.
  • For educational practitioners involved in reading assessment of older readers, tasks of prosodic awareness are a more age‐appropriate measure of phonology.
  • Tasks of phonology and reading with increasing complexity impose greater demands on the executive system. The relationship between cognitive flexibility and reading needs to be considered in theoretical models of reading.

To explore the importance of text cohesion, we conducted two experiments. We measured online (reading times) and offline (comprehension accuracy) processes for texts that were high and low cohesion. In study one (n?=?60), we manipulated referential cohesion using noun repetition (high cohesion) and synonymy (low cohesion). Students showed enhanced comprehension accuracy and faster comprehension responses for text that were high in referential cohesion. In study two (n?=?52), we examined connective text designs (‘because’, ‘and’ and ‘no connective’). Students demonstrated enhanced reading times for text using a ‘because’ connective. Additionally, we examined the individual differences (reading ability, science self-concept and self-esteem) as predictors of achievement with science comprehension tasks. Across both experiments reading ability predicted comprehension with both high (noun-repetition text and ‘and’ text) and low cohesion text (synonym text and ‘no connective’ text). These findings highlight the importance of good reading abilities and text cohesion for promoting science comprehension and learning.  相似文献

Poor readers (PRs) and controls (i.e., normal readers) from the second, fourth, and sixth grades were compared on four tasks chosen to measure the development of selective attention. The PRs performed more poorly than controls on the central but not on the incidental portion of an auditory memory task. The differences on the central task were interpreted as a function of group differences in mnemonic skills rather than selective attention. There were no group differences on either central or incidental portions of a visual memory task. In a speeded classification task, PRs exhibited a slower rate of information processing, measured in bits of information transmitted per second, than controls, but this difference in rate was not affected by distraction. On a dichotic listening task, PRs performed more poorly than controls under a variety of conditions in which the presence of distraction, the rate of information presentation, and attended ear were manipulated; the pattern of differences obtained, however, was not readily interpretable as a function of greater distractibility on the part of PRs than controls. As a whole, the results did not support the hypothesis that PRs show deficits in selective attention relative to age-matched normal readers. In addition, correlations computed among indices of selectivity (residualized gain scores) derived from the four tasks were uniformly low, suggesting that the four tasks did not measure the same cognitive construct. The implications for the study of reading disabilities and for the construct of selective attention in developmental studies are discussed.  相似文献

Research shows that misconceptions are usually detrimental to text comprehension. However, whether misconceptions also impair metacomprehension accuracy, that is, the accuracy with which one self-assesses one’s text comprehension, has received far less attention. We conducted a study in which we examined students’ (N = 47) comprehension and metacomprehension accuracy (prediction accuracy and postdiction accuracy) of a statistics text as a function of their statistical misconceptions. Text comprehension and metacomprehension accuracy referred to both conceptual and procedural aspects of statistics. The results showed that students who had more misconceptions achieved poorer conceptual text comprehension and, at the same time, provided more overconfident predictions of their conceptual and procedural text comprehension than students who had fewer misconceptions. In contrast, postdiction accuracy of conceptual and procedural text comprehension was not affected by misconceptions.  相似文献

This study synthesizes 79 standardized mean-change differences between control and treatment groups from 17 independent studies, investigating the effect of morphological interventions on literacy outcomes for students with literacy difficulties. Average total sample size ranged from 15 to 261 from a wide range of grade levels. Overall, morphological instruction showed a significant improvement on literacy achievement ([`(d)] \overline d  = 0.33). Specifically, its effect was significant on several literacy outcomes such as phonological awareness ([`(d)] \overline d  = 0.49), morphological awareness ([`(d)] \overline d  = 0.40), vocabulary ([`(d)] \overline d  = 0.40), reading comprehension ([`(d)] \overline d  = 0.24), and spelling ([`(d)] \overline d  = 0.20). Morphological instruction was particularly effective for children with reading, learning, or speech and language disabilities, English language learners, and struggling readers, suggesting the possibility that morphological instruction can remediate phonological processing challenges. Other moderators were also explored to explain differences in morphological intervention effects. These findings suggest students with literacy difficulties would benefit from morphological instruction.  相似文献

Performance on a standardized reading comprehension test reflects the number of correct answers readers select from a list of alternate choices, but fails to provide information about how readers cope with the various cognitive demands of the task. The aim of this study was to determine whether three groups of readers: normally achieving (NA), poor comprehenders (CD), with no decoding disability, and reading disabled (RD), poor comprehenders with poor decoding skills, differed in their ability to cope with reading comprehension task demands. Three task variables reflected in the question-answer relations that appear on standardized reading comprehension tests were identified.Passage Independent (PI) question can be answered with reasonable accuracy based on the reader's prior knowledge of the passage content.Inference (INFER) questions required the reader to generate an inference at the local or global test level.Locating (LOCAT) questions require the reader to match the correct answer choice to a detail explicitly stated in the text either verbatim or in paraphrase form. The relations among reader characteristics, cognitive task factors and reading comprehension test scores were analyzed using a structural relations equation with LISREL. It was found that the three reading groups differed with respect to the underlying relationship between their performance on specific question-answer types and their standardized reading comprehension score. For the NA group, a high score on PI was likely to be accompanied by a low score on INFER, whereas in the CD and RD groups, PI and INFER are positively related. The finding of a negative relationship between background knowledge and inference task factors for normally achieving readers suggests that even normal readers may have comprehension difficulties that go undetected on the basis of a standardized scores. This study indicates that current comprehension assessments may not be adequate for assessing specific reading difficulties and that more precise diagnostic tools are needed.  相似文献

The present study examined the visual scanning hypothesis, which suggests that fluent oculomotor control is an important component underlying the predictive relationship between Rapid Automatized Naming (RAN) tasks and reading ability. Our approach was to isolate components of saccadic planning, articulation, and lexical retrieval in 3 modified RAN tasks. We analyzed 2 samples of undergraduate readers (ages 17–27). We evaluated the incremental contributions of these components and found that saccadic planning to nonlinguistic stimuli alone explained roughly one third of the variance that conventional RAN tasks explained in eye movements registered during text reading for comprehension. We conclude that the well-established predictive role of RAN for reading performance is in part due to the individual ability to coordinate rapid sequential eye movements to visual nonlinguistic stimuli.  相似文献

The aim of the study was to elucidate the nature and efficiency of the strategies that readers with phonological dyslexia use for temporary retention of written words in Working Memory (WM). Data was gathered through a paradigm whereby participants had to identify serially presented written (target) words from within larger word pools according to their presentation order, with word pools containing code-specific distracter (CSD) words and non-code-specific distracter (NCSD) words. Analyses focused on three aspects of performance: (1) false recognition of target words; (2) correct recognition of target words; and (3) retention of word presentation order. Participants were readers with diagnosed phonological dyslexia (n = 20, mean grade level = 9.05 [0.89]) and a control group of regular readers (n = 25, mean grade level = 9.00 [0.76]). Results provide direct evidence that the dyslexic readers and the regular readers used essentially different memory coding strategies for the temporary retention of written words, with the former predominantly relying on a visual strategy and the latter on a phonological strategy. Findings further pinpointed a notably impoverished ability of the dyslexic readers to retain word presentation order. The implication of these findings is discussed in relation to theories predicting the acquisition and mastery of reading.
