The Effects of Readers' Misconceptions on Comprehension of Scientific Text.

The aim of the present study was to investigate the effects of readers' misconceptions on text comprehension. College students with misconceptions in science were asked to read and recall a text that contradicted their misconceptions. Students with no misconceptions served as the control group. Both online (think-aloud, reading times) and offline (recall) measures were obtained. The results suggest that readers' misconceptions often do not affect the online processes themselves but do influence the content of those processes and, consequently, the offline memory representation for the text after reading is completed.

Reading in graduate school: A survey of doctoral students in clinical psychology.

To what extent do graduate students in clinical psychology complete assigned readings? A total of 744 graduate students in American Psychological Association-accredited doctoral programs completed an online survey regarding reading in graduate school (67% response rate, of those viewing the survey). The reported amount of assigned reading varied widely, with an average of 330 pages per week. Compliance ratings suggested that about half the assigned reading is completed thoroughly and that thorough reading is more common than skimming or not reading assigned material. Motivating and hindering factors for reading are reported, and implications for faculty are considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Changes in perceptual, motor and reading test scores in a remedial reading group.

Two matched groups each composed of nine children with reading problems were compared on a number of perceptual, motor, and reading tests. One group was thereafter exposed to a special remedial program. On retest this group showed significant gains in reading as well as in some of the perceptual and motor areas. No similar improvement was detected in the control group denied the remedial treatment. Not all perceptual tests showed a parallel improvement with reading and the implications of this finding are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Learning what's taught: Sex differences in instruction.

Research indicates that boys perform better on mathematics tests and girls perform better on reading tests. An investigation of why boys' and girls' performance differs was made by coding 33 teacher interactions with 2nd grade students during reading and mathematics instruction. Teachers made more academic contacts with girls in reading and with boys in math; teachers spent relatively more cognitive time with girls in reading and boys in math; teachers made consistently more managerial contacts with boys than girls; and, although there were no differences in initial abilities, sex differences were found in end-of-year achievement in reading.

Using working memory theory to investigate the construct validity of multiple-choice reading comprehension tests such as the SAT.

When taking multiple-choice tests of reading comprehension such as the Scholastic Assessment Test (SAT), test takers use a range of strategies that vary in the extent to which they emphasize reading the questions versus reading the passages. Researchers have challenged the construct validity of these tests because test takers can achieve better-than-chance performance even if they do not read the passages at all. By using an individual-differences approach that compares the relative power of working memory span to predict SAT performance for different test-taking strategies, the authors show that the SAT appears to be tapping reading comprehension processes as long as test takers engage in at least some reading of the passages themselves.

Gender differences in adult readers: A process perspective.

Explored the underlying structure of the reading scores of 235 men and 163 women (aged 17–64 yrs) using separate speed and accuracy measures from tests of reading comprehension and vocabulary. Gender differences were then examined with respect to both overall reading measures and the underlying basic processes. Speed and accuracy measures of basic processes involved in the reading of single words revealed reading differences which support the findings from the general reading tests. It was concluded that the female advantage in verbal tasks relates primarily to faster and more accurate use of lexical and orthographic knowledge, but that this accuracy advantage disappears when the reading task requires higher order processing skills. This work suggests that exploration of the speed and accuracy components of basic processing tasks is a fruitful approach to understanding individual differences, such as those related to gender.

Gender differences in beliefs and achievement: A cross-cultural study.

Gender differences on tests of achievement in reading and mathematics, and on tests of cognitive ability, were assessed. Ss were children in kindergarten and Grades 1 and 5 in elementary schools in Taiwan, Japan, and the US (ns?=?1,975 to 4,266). Few gender differences were observed on curriculum-based tests of math computation and reading. Boys were more effective, however, in solving word problems and in answering questions involving estimation, visualization, and measurement. Cognitive tests revealed some gender differences at the 5th-grade level in all 3 cultures. Children and their mothers tended, as early as the 1st grade, to believe that boys were better at math and girls were better at reading. Children in the 3 cultures differed consistently in their scores in reading and math, but there were very few interactions between gender and location. The lack of frequent significant interactions between gender and location indicated the gender effects for both achievement scores and ratings were equivalent across Chinese, Japanese, and American contexts.

Comparing the reading-storage test to the paraphrase test as measures of the primary effect of prose reading.

Compared reading-storage tests to paraphrase tests to determine the sensitivity of each to the gain in comprehension that results from reading prose. In Exp I, 48 college students were presented tests on 8 passages at 4 levels of difficulty under reading and nonreading conditions. In Exp II, 40 college students were presented tests on 5 passages with the amount of information in the passages systematically manipulated using a word deletion scheme. The reading-storage tests were, on the average, less sensitive to gain than the paraphrase tests, but gain on the paraphrase tests was more variable. The reading-storage test is a completely objective technique which appears to be about as sensitive to comprehension gain as is the subjectively developed paraphrase type of test.

Seven-year longitudinal study of the early prediction of reading achievement.

Investigated how well a broad, comprehensive battery of tests administered in kindergarten to 286 Ss (aged 5.0–7.1 yrs) predicted reading achievement in Grades 1–6. The test variables were reduced to 6 predictive factors by factor analysis that, together with the S's sex and the parent's language, had multiple correlations with reading achievement of .58 (Grade 1), .65 (Grade 2), .70 (Grade 3), .66 (Grade 6), and .71 (across all reading achievement tests). Path analysis showed that characteristics measured in kindergarten directly influenced reading in early primary grades and that early reading achievement was the primary determinant of later reading performance. It is concluded that the use of a 2-stage testing procedure, a preliminary screening device followed by the full test battery for selected Ss, substantially reduced testing time and resources, but it had almost no effect on the accuracy of predictions in the present study.

Effects of age, speed of processing, and working memory on comprehension of sentences with relative clauses.

Two hundred participants, 50 in each of four age ranges (19–29, 30–49, 50–69, 70–90) were tested for working memory, speed of processing, and the processing of sentences with relative clauses. In Experiment 1, participants read four sentence types (cleft subject, cleft object, subject-subject, subject-object) in a word-by-word, non-cumulative, self-paced reading task and made speeded plausibility judgments about them. In Experiment 2, participants read two types of sentences, one of which contained a doubly center embedded relative clause. Older participants' comprehension was less accurate and there was age-related slowing of online processing times in all but the simplest sentences, which increased in syntactically complex sentences in Experiment 1. This pattern suggests an age-related decrease in the efficiency of parsing and interpretation. Slower speed of processing and lower working memory were associated with longer online processing times only in Experiment 2, suggesting that task-related operations are related to general speed of processing and working memory. Lower working memory was not associated with longer reading times in more complex sentences, consistent with the view that general working memory is not critically involved in online syntactic processing. Longer online processing at the most demanding point in the most demanding sentence was associated with better comprehension, indicating that it reflects effective processing under some certain circumstances. However, the poorer comprehension performance of older individuals indicates that their slower online processing reflects inefficient processing even at these points.

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.     

HIV-AIDS Patients' Evaluation of Health Information on the Internet: The Digital Divide and Vulnerability to Fraudulent Claims.

Access to health information on the Internet has revolutionized how medical patients learn about their illnesses. Valuable information can be found online; however, many health Web sites contain inaccurate or misleading information. The authors surveyed 324 adults with HIV concerning their Internet use for obtaining health information. Health information found online was then rated for quality by participants and by medical professionals. Participants were less critical of health information found online than medical professionals and made smaller distinctions between high-quality and low-quality information. Assigning credibility to low-quality information was predicted by lower incomes and educational attainment, poorer reading comprehension, lower literacy levels, and irrational health beliefs. Results suggest that patients do not always evaluate online information critically and may be vulnerable to misinformation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Phonological typicality influences sentence processing in predictive contexts: Reply to Staub, Grant, Clifton, and Rayner (2009).

In 2 separate self-paced reading experiments, Farmer, Christiansen, and Monaghan (2006) found that the degree to which a word's phonology is typical of other words in its lexical category influences online processing of nouns and verbs in predictive contexts. Staub, Grant, Clifton, and Rayner (2009) failed to find an effect of phonological typicality when they combined stimuli from the separate experiments into a single experiment. We replicated Staub et al.'s experiment and found that the combination of stimulus sets affects the predictiveness of the syntactic context; this reduces the phonological typicality effect as the experiment proceeds, although the phonological typicality effect was still evident early in the experiment. Although an ambiguous context may diminish sensitivity to the probabilistic relationship between the sound of a word and its lexical category, phonological typicality does influence online sentence processing during normal reading when the syntactic context is predictive of the lexical category of upcoming words.

A family study of autism: cognitive patterns and levels in parents and siblings

First-degree relatives of 99 autism probands and of 36 Down's syndrome controls were assessed with standardised tests of intellectual functioning, reading, and spelling. Higher mean verbal IQ scores, and discrepancies in favour of verbal scores, were characteristic of autism relatives. No consistent differences were found on performance scales, reading, and spelling tests. Among autism relatives, siblings affected with the broad phenotype of autism had significantly lower IQ scores and poorer reading and spelling performances than unaffected siblings. However, the small size of the cognitive difference and the lack of a distinctive cognitive profile indicates that standardised cognitive measures used in this study are unlikely to improve the operationalised definition of the broad phenotype of autism. The slightly superior verbal performance of relatives in the autism group might represent some form of heterozygote advantage.     

Regulation of heat shock protein 27 expression of prostatic cells in response to heat treatment

BACKGROUND: Reading acuity as well as reading speed are good predictors of everyday visual function. As visual acuity tests are poor predictors of the real-world function, performance-based tests, e.g., reading speed measurements, can be used for the determination of visual function. Thus, a German reading chart was developed in order to evaluate reading acuity as well as reading speed. METHODS: Print size is defined as the height of a lower case x and progresses logarithmically from one phrase to another (factor: 1.25). Reading acuity is determined in LogRAD (Reading Acuity Determination). 32 short German phrases were created, comparable concerning grammatical difficulty as well as in number (n = 14), length and position of words. The reading speed parameters measured with a stop-watch in 160 persons (aged: Phi = 21a +/- 3.8a) were calculated in words per minute (w/min). Out of the 32 phrases the 24 most similar ones were selected statistically and used for the reading charts (Radner Reading Charts). With these reading charts a reading acuity score (LogRAD-score) can be calculated considering reading errors in words of different length. Reading speed can be determined at the same time. Reading acuity (LogRAD-Score) was measured in 32 normal eyes of 16 students and compared to the angular visual acuity (LogMAR). RESULTS: The mean reading speed of the test persons was 211.8 +/- 34.1 w/min. 24 phrases fulfilled the test item criteria for the reading chart: mean +/- 0.25 x SD. The reliability analyses yielded an overall Cronbach's alpha coefficient of 0.98! The mean visual acuity measured in 32 eyes was -0.115 +/- 0.097 LogMAR and the mean reading acuity score was +0.026 +/- 0.091 LogRAD. The mean difference was +0.104 +/- 0.066 and the correlation between LogMAR and LogRAD was good (r = 0.59). CONCLUSIONS: With these reading charts it is for the first time possible to simultaneously determine reading acuity as well as reading speed in German. The high reliability of the 24 phrases and the high correlation between LogMAR and LogRAD leads us to expect a good reproducibility of the reading acuity evaluations. For the "Radner Reading Charts" we have shown that print size is the main reason for changes of reading speed.     

A quasi-experimental validation of transactional strategies instruction with low-achieving second-grade readers.

Second-grade, low-achieving students experienced a year of either transactional strategies instruction or highly regarded, more conventional second-grade reading instruction. By the end of the academic year, there was clear evidence of greater strategy awareness and strategy use, greater acquisition of information from material read in reading group, and superior performance on standardized reading tests by the transactional strategies instruction students. This is the clearest validation to date of educator-developed transactional strategies instruction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Serial order ability in good and poor readers.

Tested a poor reading group (16 4th graders, 2 yr. behind their appropriate reading level) and a good reading group (16 4th graders with average reading scores between the 33rd and 70th percentiles) on sequencing and nonsequencing tests in the auditory, visual, and tactual modes. No differences were found between the performance of good and poor reader groups on the ability to sequence. Results are discussed in terms of perceptual vs. linguistic sequencing abilities.

Rereading Effects Depend on Time of Test.

Previous research has shown better text learning after rereading versus 1 reading of a text. However, rereading effects have only been explored using immediate tests, whereas most students face delays between study and test. In 2 experiments, 423 college students read a text once, twice in massed fashion, or twice with 1 week between trials. Students were tested either immediately or 2 days after study. On an immediate test, performance was greater after massed versus single reading, whereas performance for distributed rereading was not significantly greater than after single reading. On a delayed test, performance was greater after distributed versus single reading, whereas performance for massed rereading and single reading no longer differed significantly.
