Proofreading errors in good and poor readers

Seven-year-old children classified as good and poor readers carried out a proofreading task on two passages varying in level of difficulty. Misspellings were introduced by transposing two adjacent letters in the work "the," other three-letter words, and longer words. While both groups of readers were able to identify the correct spelling of the misspelled words on a spelling test, poor readers made significantly more proofreading errors. Word length had a significant effect on performance, indicating that sensitivity to word configuration is important for successful proofreading. The pattern of proofreading errors did not reflect underlying differences which might relate to strategies used by the two groups in normal reading. The results are compared with those from other proofreading and letter detection experiments in order to highlight methodological implications when such tasks are used to verify hypotheses concerned with normal reading strategies.     

Grammatical class effects in relation to normal and aphasic sentence processing

Agrammatic, Broca's aphasic patients, Wernicke's aphasic patients, and neurologically intact control subjects were asked to detect target letters in prose passages and in a scrambled word passage. The targets were embedded, in some instances, in content words (open-class vocabulary items), and in other instances, in function words (closed-class vocabulary items). With respect to the prose passages, both the control subjects and Wernicke's aphasic patients were more apt to notice target letters when they appeared in the open-class items than when in closed-class items; by contrast, the agrammatic Broca's patients showed no vocabulary class detection difference. The Wernicke's patients were not entirely normal, however: Whereas the normal subjects showed a much smaller vocabulary class effect for letter detection in the scrambled condition, the Wernicke's maintained the pattern they had shown in the prose condition. These and other findings obtained on the letter cancellation task are discussed in relation to lexical access mechanisms geared to sentence parsing.     

Examining misses in reading aloud repeated words

This study examined a novel task in which participants read aloud passages shown two words per line on a computer screen. There were four different passages, all of which included unrelated sentences, with each sentence containing one test word. The passages differed only in the text type (prose, scrambled) and in the identity of the test word (the, one). The word the is a common function word, whereas one is a less common content word. The test word was repeated in half of the sentences at the end of one line and at the start of the following line. Many more misses in reading aloud occurred on the than on one, especially for prose passages; almost all misses involved repeated words. These results were interpreted in terms of hypotheses and models that have been proposed for the letter-detection task. Specifically, it is concluded that reading aloud is influenced by structural processes that differentiate between function and content words.     

Syntactic competence and reading ability in children

The effect of syntactic context on auditory word identification and on the ability to detect and correct syntactic errors in speech was examined in severely reading disabled children and in good and poor readers selected from the normal distribution of fourth graders. The poor readers were handicapped when correct reading required analysis of the sentence context. However, their phonological decoding ability was intact. Identification of words was less affected by syntactic context in the severely disabled readers than in either the good or poor readers. Moreover, the disabled readers were inferior to good readers in judging the syntactical integrity of spoken sentences and in their ability to correct the syntactically aberrant sentences. Poor readers were similar to good readers in the identification and judgment tasks, but inferior in the correction task. The results suggest that the severely disabled readers were inferior to both good and poor readers in syntactic awareness, and in ability to use syntactic rules, while poor readers were equal to good readers in syntactic awareness but were relatively impaired in using syntactic knowledge productively.     

Assessing the role of different spatial frequencies in word perception by good and poor readers

Numerous studies indicate that dyslexic and nondyslexic individuals exhibit different patterns of sensitivity to spatial frequency. However, the extension of this effect to normal (nondyslexic) adults of good and poor reading abilities and the role played by different spatial frequencies in word perception have yet to be determined. In this study, using normal (nondyslexic) adults, we assessed reading ability, spatial frequency sensitivity, and perception of spatially filtered words and nonwords (using a two-alternative forced choice paradigm to avoid artifactual influences of nonperceptual guesswork). Good and poor readers showed different patterns of spatial frequency sensitivity. However, no differences in accuracy of word and nonword perception were found between good and poor readers, despite their differences in spatial frequency sensitivity. Indeed, both reading abilities showed the same superior perceptibility for spatially filtered words over nonwords across different spatial frequency bands. These findings indicate that spatial frequency sensitivity differences extend to normal (nondyslexic) adult readers and that a range of spatial frequencies can be used for word perception by good and poor readers. However, spatial frequency sensitivity may not accurately reveal an individual's ability to perceive words.     

Do children use similar processes to read and spell words?

The use of spelling-sound information in both reading and spelling was evaluated by having children read and spell nonwords and five types of words that differed in terms of their regularity for reading and spelling. The subjects were grade 3 children who had been psychometrically defined as good readers and good spellers (“good”), good readers and poor spellers (“mixed”), or poor readers and poor spellers (“poor”). Results indicated that all children attempted to use spelling-sound correspondences in both reading and spelling, although children in both the mixed and the poor groups had weaker knowledge of these correspondences and were less systematic in their use of them. Furthermore, even though the children in the mixed group had been matched with children in the good group on reading comprehension, the number and type of errors made by the mixed subjects on both the reading and spelling tasks were more similar to those of the poor subjects than to those of the good subjects.     

Recovery of Sensitivity to Prick and Touch after Pressure Block,with a Note on the Sensitivity of Hair Spots

In cloze tasks subjects are asked to supply words for deletions that occur in prose passages. In the present paper this task is related to more general word production tasks. Specifically, one aspect of decisions among several possible response alternatives was studied: the level of awareness of subjects producing competing responses. Two studies were done, differing only in the difficulty of the prose passages used as cloze tasks. In both studies, subjects (college students, n = 25) were asked to press a key hooked up to an event-graph for every option considered by them as a potential response. The main finding of the studies is that even in cases where the probability of a correct response is very low the distribution of responses considered deliberately is very small; on the average less than 1.5 words. The consequences of the finding for a theory of cloze in terms of a search and retrieval paradigm are discussed.     

Word imageability effects on naming: a pilot investigation of beginning readers of Turkish

Word imageability, a semantic variable, in naming by beginning readers of English is well documented particularly with poor readers naming high imageable words more accurately than low imageable words. The present study examined the role of imageability on word naming by 20 good and 20 poor beginning readers as a function of orthographic transparency by utilizing the peculiarities of the transparent Turkish writing system. Neither good nor poor beginning readers show any evidence of imageability for Turkish suggesting that the contribution of imageability to word naming may indeed be determined by orthographic transparency. Implications of these findings are discussed.     

Imagery, encoding specificity, and prose recall in 6-year-old children

Partial pictures depict only selected portions of prose passages. Partial pictures hypothetically aid retention by inducing young children to generate imagery for nonpictured prose. Results from two hundred eighty-eight 6-year-old children indicated that (a) partial pictures at study facilitate recall, (b) identical study and retrieval prompts facilitate recall, and (c) imagery instructions and training do not affect retention. Partial pictures apparently help children to encode information more efficiently at study, but there is no evidence that young children generate images with the aid of the partial picture cues, nor that they have a retrieval deficit for these images as suggested by M. Ruch and J. Levin.     

Detection errors on the wordthe: Evidence for the acquisition of reading levels

The Rockefeller University, New York, New York 10021 The pattern of detection errors on the wordthe made by groups of school children and adults searching four 25-word passages for instances of the target letter t was found to depend on the subjects’ reading ability as well as on the orthographic, syntactic, and semantic con-straints of the search passages. The conditional percentage of errors on the wordthe made by children reading at first-grade level was no different from that expected on the basis of chance for any of the four passages. Disproportionately more errors onthe were made on the prose and scrambled-word passages by children reading at second-grade level and above and by adults, with the difference between the prose and scrambled-word passages being significant only for the most fluent readers. These results are consistent with a multilevel model of reading, and are taken to support the hypothesis that reading-processing skills at various levels are acquired at different rates.     

Memory for item order and phonetic recoding in the beginning reader

A defect in immediate memory for item order is often attributed to poor beginning readers. We have supposed that this problem may be a manifestation of an underlying deficiency in the use of phonetic codes. Accordingly, we expected good and poor readers to differ in their ability to order stimuli that can be easily recoded as words and stored in phonetic form, but not in their ability to order nonlinguistic stimuli that do not lend themselves to phonetic recoding in short-term memory. The purpose of the present study was to test this hypothesis by examining the ability of good and poor readers to reconstruct the order of sets of briefly presented stimuli that varied in the extent to which they could be distinctively recoded into phonetic form: pictures of common objects versus nonrepresentational, “doodle” drawings. As expected, an interaction between reading ability and type of stimulus item was found, demonstrating the material-specific nature of poor readers' ordering difficulties. These findings support the hypothesis that a function of the phonetic representation is to aid in retention of order information, and that poor readers' ordering difficulties are related to their deficient use of phonetic codes.     

Vocabulary Self-Selection: A Study of Middle-School Students' Word Selections from Expository Texts

This study investigated students' decision-making as they self-selected important words from expository texts. Participants were 94 eighth graders and six adult readers. Data sources included students' written responses containing their word selections and reasons for selecting words from eight informational passages, student interviews, and word selections of adult readers. We examined the students' reasons for their word selections and compared their words with those selected by adult readers. Results indicated the following: 1) students of varying reading abilities can self-select important words in an expository passage; 2) students' reasons for selecting words differed from reasons found in related studies; and 3) variability exists across individual students and across adult readers in selecting important words in expository passages.     

Semantic and visual memory codes in learning disabled readers

Two experiments investigated whether learning disabled readers' impaired recall is due to multiple coding deficiencies. In Experiment 1, learning disabled and skilled readers viewed nonsense pictures without names or with either relevant or irrelevant names with respect to the distinctive characteristics of the picture. Both types of names improved recall of nondisabled readers, while learning disabled readers exhibited better recall for unnamed pictures. No significant difference in recall was found between name training (relevant, irrelevant) conditions within reading groups. In Experiment 2, both reading groups participated in recall training for complex visual forms labeled with unrelated words, hierarchically related words, or without labels. A subsequent reproduction transfer task showed a facilitation in performance in skilled readers due to labeling, with learning disabled readers exhibiting better reproduction for unnamed pictures. Measures of output organization (clustering) indicated that recall is related to the development of superordinate categories. The results suggest that learning disabled children's reading difficulties are due to an inability to activate a semantic representation that interconnects visual and verbal codes.     

Phonetic recoding and reading difficulty in beginning readers

The results of a recent study (Liberman, Shankweiler, Liberman, Fowler, & Fischer, 1977) suggest that good beginning readers are more affected than poor readers by the phonetic characteristics of visually presented items in a recall task. The good readers made significantly more recall errors on strings of letters with rhyming letter names than on nonrhyming sequences; in contrast, the poor readers made roughly equal numbers of errors on the rhyming and nonrhyming letter strings. The purpose of the present study was to determine whether the interaction between reading ability and phonetic similarity is solely determined by different rehearsal strategies of the two groups. Accordingly, good and poor readers were tested on rhyming and nonrhyming words using a recognition memory paradigm that minimized the opportunity for rehearsal. Performance of the good readers was more affected by phonetic similarity than that of the poor readers, in agreement with the earlier study. The present findings support the hypothesis that good and poor readers do differ in their ability to access a phonetic representation.     

Automatic activation of phonology in silent reading is parallel: evidence from beginning and skilled readers

The picture-word interference paradigm was used to shed new light on the debate concerning slow serial versus fast parallel activation of phonology in silent reading. Prereaders, beginning readers (Grades 1-4), and adults named pictures that had words printed on them. Words and pictures shared phonology either at the beginnings of words (e.g., DOLL-DOG) or at the ends of words (e.g., FOG-DOG). The results showed that phonological overlap between primes and targets facilitated picture naming. This facilitatory effect was present even in beginning readers. More important, from Grade 1 onward, end-related facilitation always was as strong as beginning-related facilitation. This result suggests that, from the beginning of reading, the implicit and automatic activation of phonological codes during silent reading is not serial but rather parallel.     

Abstractness and prose comprehension

One hundred twenty eight high school subjects read abstract or concrete versions of two 79-word passages. The passages were presented either intact or serially with syntactic or random word orders. Protocols were scored for total words recalled, the number of content and function words recalled, and the number of high-thematic intrusions produced. All main effects were significant in each of the four analyses. The independent variables were apparently all effective in increasing the thematic integrity of the prose passages, which in turn led to enhanced recall. The findings represent an extension and clarification of Yuille and Paivio (1969).     

Repetition and comprehension of spoken sentences by reading-disabled children

The language problems of reading-disabled elementary school children are not confined to written language alone. These children often exhibit problems of ordered recall of verbal materials that are equally severe whether the materials are presented in printed or in spoken form. Sentences that pose problems of pronoun reference might be expected to place a special burden on short-term memory because close grammatical relationships obtain between words that are distant from one another. With this logic in mind, third-grade children with specific reading disability and classmates matched for age and IQ were tested on five sentence types, each of which poses a problem in assigning pronoun reference. On one occasion the children were tested for comprehension of the sentences by a forced-choice picture verification task. On a later occasion they received the same sentences as a repetition test. Good and poor readers differed significantly in immediate recall of the reflexive sentences, but not in comprehension of them as assessed by picture choice. It was suggested that the pictures provided cues which lightened the memory load, a possibility that could explain why the poor readers were not demonstrably inferior in comprehension of the sentences even though they made significantly more errors than the good readers in recalling them.     

Infants' long-term memory for the sound patterns of words and voices

Infants' long-term memory for the phonological patterns of words versus the indexical properties of talkers' voices was examined in 3 experiments using the Headturn Preference Procedure (D. G. Kemler Nelson et al., 1995). Infants were familiarized with repetitions of 2 words and tested on the next day for their orientation times to 4 passages--2 of which included the familiarized words. At 7.5 months of age, infants oriented longer to passages containing familiarized words when these were produced by the original talker. At 7.5 and 10.5 months of age, infants did not recognize words in passages produced by a novel female talker. In contrast, 7.5-month-olds demonstrated word recognition in both talker conditions when presented with passages produced by both the original and the novel talker. The findings suggest that talker-specific information can prime infants' memory for words and facilitate word recognition across talkers.     

A blank look in reading: the effect of blank space on the identification of letters and words during reading

Two experiments investigated the effect of visual blank space on reading by varying the amount of interletter and interline blank space in prose passages. Increasing interletter blank spacing slowed the reading process overall, presumably because it disrupted the unitization of words and word identification, but it also improved the identification of the letters within words. By contrast, increasing interline blank spacing sped up the reading process overall, while also improving the identification of words and the letters within words, presumably because the extra spacing reduced the amount of visual information that was processed during reading. The latter finding supports the conclusion that information from surrounding lines of single-spaced text may interfere with reading.
