METACOMPREHENSION KNOWLEDGE AND COMPREHENSION OF EXPOSITORY AND NARRATIVE TEXTS AMONG YOUNGER AND OLDER ADULTS

In the present study we investigated the relations between younger and older adults' metacomprehension knowledge and their comprehension of expository and narrative texts as well as their self-perceptions of comprehension evaluation ability. We employed the Metacomprehension Scale (MCS) designed by Moore, Zabrucky, and Commander (1997a) to assess readers' metacomprehension knowledge; adults' self-perceived comprehension evaluation ability was measured using a Likert scale. Results indicate that metacomprehension knowledge as measured by the MCS was a reliable predictor of comprehension performance and self-perceptions of comprehension evaluation ability in younger and older adults. However, younger and older adults' comprehension was best predicted by different components of metacomprehension knowledge, and metacomprehension knowledge better predicted comprehension of expository than narrative texts.     

Validation of the Metacomprehension Scale

Evidence for the factorial, convergent and discriminant, and criterion-related validity of the Metacomprehension Scale (MCS) was examined in a sample of 237 young adults. The instrument was factorially heterogeneous but exhibited homogeneity within each of the seven subscales. Evidence for the convergent and discriminant validity of the MCS was examined by correlating the subscales from the MCS with subscales from metacognitive questionnaires measuring similar constructs from related domains. In general, correlations within constructs were larger than correlations between constructs, providing preliminary evidence of the convergent and discriminant validity of the MCS. The criterion-related validity of the MCS relative to other metacognitive measures was examined by using the metacognitive measures and the MCS to predict comprehension performance. The MCS predicted performance better than the other measures of metacognition and accounted for variance in performance not accounted for by the other measures. These results show promise for the value of self-assessments of metacomprehension.     

ADULT AGE DIFFERENCES IN SPEED AND ACCURACY OF MATCHING VERBAL AND PICTORIAL SIGNS

Young (mean age of 19 years) and older (mean age of 69 years) adults participated in a two‐choice, matching‐to‐sample reaction time experiment. Young adults responded more quickly than older adults; all subjects responded more quickly to a verbal standard sign than to a pictorial standard. However, there was an age difference in speed of performance only for those subjects in the stimulus order condition receiving first pictorial standards and then verbal standards. These data are interpreted within a model of dual memory processing systems (verbal and nonverbal). During adulthood there is an increasing tendency for verbal codes to elicit more general associations of both a verbal and a pictorial symbolic nature, while a pictorial code continues to activate only other pictorial stimuli. More generally, the implications of such a model for understanding aging and educational gerontology are discussed.     

Measuring college students' reading comprehension ability using cloze tests

Recent investigations challenge the construct validity of sustained silent reading tests. Performance of two groups of post‐secondary students (e.g. struggling and non‐struggling) on a sustained silent reading test and two types of cloze test (i.e. maze and open‐ended) was compared in order to identify the test format that contributes greater variance in reading comprehension. One hundred participants were recruited from students enrolled in a preparatory course for a high‐stakes statewide reading examination. Our results suggest that all three measures have good concurrent validity. There was no evidence that open‐ended cloze performance was more related to verbal ability than any other reading measure. Maze performance did the best job at discriminating between our struggling and non‐struggling readers. Implications for reading comprehension assessment in post secondary‐aged adults are discussed.     

MEMORY FOR PICTORIAL INFORMATION AND THE PICTURE SUPERIORITY EFFECT

This research compared the performance of younger (mean age — 20.7 years) and older (mean age–68.3 years) adults on a memory task that involved pictures, words, and pictures‐plus‐words as stimuli. The results, consistent with previous research, indicated an equivalent picture superiority effect for both young and old adults when pictures were compared to words. More specifically, although recall scores were significantly higher for younger adults compared to older adults, the superior recall scores for pictures versus words did not differ between the age groups. However, the performance of older adults declined markedly, compared to the younger adults, in the picture‐plus‐word condition. These findings are interpreted as providing support for a divided attention model, which involves effortful processing of both visual and verbal aspects of stimuli. This situation of divided attention appears to put older adults at a relative disadvantage compared to young adults.     

Adult Metacomprehension: Judgment Processes and Accuracy Constraints

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.     

THE EFFECTS OF VIOLATIONS OF UNIDIMENSIONALITY ON THE ESTIMATION OF ITEM AND ABILITY PARAMETERS AND ON ITEM RESPONSE THEORY EQUATING OF THE GRE VERBAL SCALE

One of the major assumptions of item response theory (IRT)models is that performance on a set of items is unidimensional, that is, the probability of successful performance by examinees on a set of items can be modeled by a mathematical model that has only one ability parameter. In practice, this strong assumption is likely to be violated. An important pragmatic question to consider is: What are the consequences of these violations? In this research, evidence is provided of violations of unidimensionality on the verbal scale of the GRE Aptitude Test, and the impact of these violations on IRT equating is examined. Previous factor analytic research on the GRE Aptitude Test suggested that two verbal dimensions, discrete verbal (analogies, antonyms, and sentence completions)and reading comprehension, existed. Consequently, the present research involved two separate calibrations (homogeneous) of discrete verbal items and reading comprehension items as well as a single calibration (heterogeneous) of all verbal item types. Thus, each verbal item was calibrated twice and each examinee obtained three ability estimates: reading comprehension, discrete verbal, and all verbal. The comparability of ability estimates based on homogeneous calibrations (reading comprehension or discrete verbal) to each other and to the all-verbal ability estimates was examined. The effects of homogeneity of item calibration pool on estimates of item discrimination were also examined. Then the comparability of IRT equatings based on homogeneous and heterogeneous calibrations was assessed. The effects of calibration homogeneity on ability parameter estimates and discrimination parameter estimates are consistent with the existence of two highly correlated verbal dimensions. IRT equating results indicate that although violations of unidimensionality may have an impact on equating, the effect may not be substantial.     

A Component Analysis of Metacognition in Reading Comprehension: The Contributions of Awareness and Self‐Regulation

The purpose of this study was to examine the relative effects of awareness of purpose and self‐regulated strategies in metacomprehension training. Thirty‐six students identified as having reading difficulties were either trained to cue themselves to the purpose of reading (awareness of purpose alone) or to employ an underlining strategy (awareness of purpose and a self‐regulated strategy) to enhance reading comprehension. Training was conducted during four, 30‐minute training sessions with follow‐up probes taken 7 to 10 days later. Students trained to underline key words and phrases as they read a passage answered more comprehension questions on an acquisition probe and recalled more propositions on acquisition and generalization probes. Although cueing students to the purpose of reading was beneficial, the combination of awareness of purpose and employment of a self‐regulated strategy generated better comprehension performance.     

Comprehension of Health-related Written Materials by Older Adults

This study examined how Flesch Reading Ease and text cohesion affect older adults' comprehension of common health texts. All older adults benefited when high Flesh Reading Ease was combined with high cohesion. Older adults with small working memories had more difficulty understanding texts high in Flesch Reading Ease. Additionally, older adults with low verbal ability or older than 77 years of age had difficulty understanding texts high in text cohesion but low in Flesch Reading Ease. These results imply that writers must increase Flesch Reading Ease without disrupting text cohesion to ensure comprehension of health-related texts.     

Explanation generation, not explanation expectancy, improves metacomprehension accuracy

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.     

The double curse of misconceptions: misconceptions impair not only text comprehension but also metacomprehension in the domain of statistics

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.     

Scaffolding cognitive and metacognitive processes in low verbal ability learners: Use of diagrams in computer-based training environments

This study investigated how instructionalstrategies can support learners' knowledgeacquisition and metacomprehension of complexsystems in a computer-based trainingenvironment, and how individual characteristicsinteract with these manipulations. Incorporating diagrams into the trainingfacilitated performance on measures ofintegrative knowledge (i.e., the integrationand application of task-relevant knowledge),but had no significant effect on measures ofdeclarative knowledge (i.e., mastery of basicfactual knowledge). Diagrams additionallyfacilitated the development of accurate mentalmodels (as measured via a card sorting task)and significantly improved the instructionalefficiency of the training (i.e., higher levelof performance was achieved with less mentaleffort). Finally, diagrams effectivelyscaffolded participants' metacognition,improving their metacomprehension accuracy(i.e., their ability to accurately monitortheir comprehension). These beneficial effectsof diagrams on learners' cognitive andmetacognitive processes were found to bestrongest for participants with low verbalability. Results are discussed in terms ofimplications for the design of adaptivelearning systems.     

Concurrent and Longitudinal Contributions of a Brief Assessment of Reading‐Specific Executive Function to Reading Comprehension in First and Second Grade Students

Executive function (EF) contributes significantly to reading comprehension across the lifespan. Emerging research indicates domain‐specific assessments of EF are better suited for assessment and intervention in academic contexts. For example, graphophonological‐semantic cognitive flexibility (GSF), the ability to flexibly switch between the graphophonological and semantic components of printed words, contributes uniquely to reading comprehension across the lifespan, and GSF training improves children's reading comprehension. This study compared the original GSF measure, which is problematic for use in schools due to its subjectively interpreted explicit explanation component, to an abbreviated implicit task that is better suited for assessment of GSF in practical contexts in 68 first and second grade students. Implicit and explicit GSF contributed uniquely to reading comprehension concurrently and longitudinally when children (n = 31) were in third and fourth grades, beyond verbal ability, decoding ability, and matrix reasoning.     

TEACHING READING COMPREHENSION TO LEARNERS WITH AUTISM SPECTRUM DISORDER: PREDICTORS OF TEACHER SELF‐EFFICACY AND OUTCOME EXPECTANCY

Learners with autism spectrum disorder (ASD) often exhibit difficulty in the area of reading comprehension. Research connecting the learning needs of individuals with ASD, existing effective practices, teacher training, and teacher perceptions of their own ability to teach reading comprehension is scarce. Quantitative survey methodology and hierarchical regression analysis were utilized to investigate teacher preparedness to use effective practices, along with the job‐related factors of experience, administrator support, learner verbal ability, and instructional setting, as predictors of (1) teacher perceived self‐efficacy and (2) teacher perceived outcome expectancy teaching reading comprehension to learners with ASD. Study findings, based on 112 teacher participants, indicate that teachers with a higher confidence in using effective practices have both a higher perception of their own ability to teach comprehension (self‐efficacy), and a higher expectation of their own ability to increase instructional outcomes in learners with ASD (outcome expectancy). Implications for practice include professional development recommendations and provision of ongoing support from principals and administrators.     

PHYSIOLOGICAL INDICATORS OF STRESS AND INTELLECTUAL PERFORMANCE AMONG ANXIOUS OLDER ADULTS

The purpose of this study was to gain a better understanding of the relationship between anxiety and cognitive performance in older adults. We asked 27 older adults, self‐selected on the basis of their concerns about decrements in intellectual functioning, to perform a series of cognitive tasks to assess crystallized (Gc) and fluid (Gf) intellectual abilities. Volunteers also completed questionnaires concerning their beliefs about their task performance specific to each ability, as well as measures of both generalized and intellectual self‐efficacy, everyday cognitive failures, and concerns about illness and aging. Cortisol was measured as an indicator of anxiety and Epstein‐Barr virus levels were assessed to determine nonspecific physiological changes. Results indicated that in the self‐selected “anxious” sample, there was a significant negative correlation between cortisol and self‐efficacy related to the most difficult measure of Gf. The only other significant (negative) correlation was between cortisol and generalized self‐efficacy. As expected, EBV levels were not correlated with any of the performance or self‐efficacy measures taken. Possible explanations of these findings are discussed as they relate to varying levels of performance and concerns about the loss of skills among older adults.     

The specific involvement of verbal and visuospatial working memory in hypermedia learning

Many models have hypothesized that multimedia comprehension requires the concurrent processing of verbal and visuospatial information by limited information processing systems. However, in spite of the emphasis devoted to the concurrent processing of verbal and visuospatial information, little research has so far investigated the specific role played by verbal and visuospatial abilities in multimedia comprehension. The present paper aims to study the specific involvement of verbal and visuospatial working memory in multimedia learning. Ninety‐two students (39 boys and 53 girls) from a middle school in a small city in the northeast of Italy, were asked to learn new information on the physical and social geography of Germany from a hypermedium. Participants were also required to perform a reading comprehension test, two short‐term memory tasks, and two working memory tasks, which assessed either verbal or visuospatial memory. The results support the hypothesis that both verbal and visuospatial working memory sub‐components play a role in hypermedium processing, but with specific and distinct functions: the performance in the verbal working memory task was able to predict the semantic knowledge children can derive from hypermedia learning. In contrast, visuospatial working memory seemed to have lower connections to the semantic knowledge children derived from a hypermedia document, whereas its role emerged in the ability to construct a representation of the document structure.     

Metacomprehension effects situated within an anchoring and adjustment framework

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.     

Imagery and Verbal Ability and Recognition Memory for Pictures and Words in Males and Females

Objective and subjective indices of imagery and verbal ability and their relationship to recognition memory for pictures and concrete words were examined in a large correlational study. Objective spatial tests of imagery proved to be better predictors of picture recognition than were self‐assessments, the Flags test excepted. Spatial tests also predicted word memory in males, but not females. Imagery control and imagery vividness bore little relation to recognition; vividness within specific modalities may have some influence, however, particularly in males. Verbal fluency and verbal comprehension were either unrelated or marginally negatively related to performance. In general, a more specialised pattern of ability‐performance correlations emerged for females than for males.     

Cognitive Difficulties in Struggling Comprehenders and Their Relation to Reading Comprehension: A Comparison of Group Selection and Regression-Based Models

ABSTRACT

Difficulties suppressing previously encountered but currently irrelevant information from working memory characterize less skilled comprehenders in studies in which they are matched to skilled comprehenders on word decoding and nonverbal IQ. These “extreme” group designs are associated with several methodological issues. When sample size permits, regression approaches permit a more accurate estimation of effects. Using data for students in Grades 6 through 12 (n = 766), regression techniques assessed the significance and size of the relation of suppression to reading comprehension across the distribution of comprehension skill. After accounting for decoding efficiency and nonverbal IQ, suppression, measured by performance on a verbal proactive interference task, accounted for a small amount of significant unique variance in comprehension (less than 1%). A comparison of suppression in less skilled comprehenders matched to more skilled comprehenders (48 per group) on age, word reading efficiency, and nonverbal IQ did not show significant group differences in suppression. The implications of the findings for theories of reading comprehension and for informing comprehension assessment and intervention are discussed.     

Do illustrations help or harm metacomprehension accuracy?

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.
