Learning to read facilitates the retrieval of phonological representations in rapid automatized naming: Evidence from unschooled illiterate,ex‐illiterate,and schooled literate adults

Rapid automatized naming (RAN) of visual items is a powerful predictor of reading skills. However, the direction and locus of the association between RAN and reading is still largely unclear. Here, we investigated whether literacy acquisition directly bolsters RAN efficiency for objects, adopting a strong methodological design, by testing three groups of adults matched in age and socioeconomic variables, who differed only in literacy/schooling: unschooled illiterate and ex‐illiterate, and schooled literate adults. To investigate in a fine‐grained manner whether and how literacy facilitates lexical retrieval, we orthogonally manipulated the word‐form frequency (high vs. low) and phonological neighborhood density (dense vs. spare) of the objects' names. We observed that literacy experience enhances the automaticity with which visual stimuli (e.g., objects) can be retrieved and named: relative to readers (ex‐illiterate and literate), illiterate adults performed worse on RAN. Crucially, the group difference was exacerbated and significant only for those items that were of low frequency and from sparse neighborhoods. These results thus suggest that, regardless of schooling and age at which literacy was acquired, learning to read facilitates the access to and retrieval of phonological representations, especially of difficult lexical items.     

Age changes in the missing-letter effect revisited

When participants search for a target letter while reading, they make more omissions if the target letter is embedded in frequent function words than in less frequent content words. Reflecting developmental changes in component language and literacy skills, the size of this effect increases with age. With adults, the missing-letter effect is due to both word function and word frequency. With children, it is unclear whether the growing size of the missing-letter effect across development is due to a larger effect of word function, word frequency, or both because previous studies with children seeking to isolate the influence of word frequency and word function suffer from important methodological limitations. With these methodological limitations eliminated (Experiments 1 and 2), performance in a letter detection task was assessed for children in Grades 1, 2, 3, 4, and 7 as well as for undergraduate students. The results revealed that the influence of word function increases with age, whereas the effect of frequency is fairly stable across ages. Furthermore, normative predictability data collected in Experiment 3 revealed that third graders and undergraduate students were equally good at predicting function slots in a sentence.     

Children's concept of word

The development of the concept of word as a unit of speech is a metalinguistic insight that usually corresponds to the acquisition of literacy skills. Further, as a fundamental aspect of language structure, it converges as well with skills involved in bilingualism. A framework that describes the structure of metalinguistic awareness is applied to this task in order to relate the development of word concept to literacy and bilingualism. Children between 4 and 6 years old who are prereaders or early readers, and bilingual or monolingual, are given three tests of word concept. The results show that concept of word emerges gradually and is evident to some extent even in the 4-year-olds. Further, literacy and bilingualism are shown to promote specific aspects of its developmentThe research reported in this paper was unded by grant No. A2559 from the Natural Sciences and Engineering Research Council of Canada. I am indebted to Sandra Owston, who assisted in conducting the study.     

Working memory and literacy as predictors of performance on algebraic word problems

Previous studies on individual differences in mathematical abilities have shown that working memory contributes to early arithmetic performance. In this study, we extended the investigation to algebraic word problem solving. A total of 151 10-year-olds were administered algebraic word problems and measures of working memory, intelligence quotient (IQ), and reading ability. Regression results were consistent with findings from the arithmetic literature showing that a literacy composite measure provided greater contribution than did executive function capacity. However, a series of path analyses showed that the overall contribution of executive function was comparable to that of literacy; the effect of executive function was mediated by that of literacy. Both the phonological loop and the visual spatial sketchpad failed to contribute directly; they contributed only indirectly by way of literacy and performance IQ, respectively.     

Intergenerational transmission of literacy skills among Filipino families

We examined the joint role of parental word reading skills and conventional home literacy environment measures among 320 Filipino low‐ to middle‐income families in Cebu City, Philippines with children aged 5–8 years old. A ranking of parent‐reported ratings of their frequency of engaging in home literacy activities and adult literacy practices revealed that book‐related behaviors were less frequently practiced relative to other behaviors, and mean ratings on the home literacy resources scale suggested a relatively print‐poor environment. Nevertheless, scale items about book reading and direct literacy instruction at home correlated with child's language and literacy skills. Structural equation modeling showed that parent's education and frequency of engaging in home literacy activities uniquely accounted for variance in child's oral language and print knowledge skills. In a second model, parent's word reading skills were significantly related to child's skills, but did not eliminate or attenuate influences from parent's education and home literacy activities. Results are important in relation to theories on the intergenerational transmission of literacy skills and the generalizability of findings from developed countries to developing country contexts.     

Atypical cerebral lateralisation in adults with compensated developmental dyslexia demonstrated using functional transcranial Doppler ultrasound

Functional transcranial Doppler ultrasound (fTCD) is a relatively new and non-invasive technique that assesses cerebral lateralisation through measurements of blood flow velocity in the middle cerebral arteries. In this study fTCD was used to compare functional asymmetry during a word generation task between a group of 30 dyslexic adults and a group of 30 non-dyslexic individuals. In light of previous evidence of atypical laterality in dyslexia, a reduced leftward asymmetry was predicted and confirmed. We know from previous research that most people with atypical language lateralisation have normal language and literacy skills: nevertheless, our results confirm that language laterality is reduced in those with dyslexia. Theoretical explanations for this apparent conundrum are discussed.     

The effect of a multicomponent literacy instruction model on literacy growth for kindergartners and first‐grade students in Chile

In the present study we examined the impact of a comprehensive literacy instruction model called Collaborative Language and Literacy Instruction Project (CLLIP) on language and literacy achievement over the course of a year by Spanish‐speaking children in Chile. Participants included kindergartners (N = 312) from high and low socioeconomic backgrounds and first‐grade students (N = 305) from high SES families. The CLLIP model targeted phonological awareness, alphabetics and phonics, fluency, vocabulary, reading comprehension and writing, and included coaching and sustained follow‐up as key elements for teacher professional development. The results showed promise for the CLLIP model in the Chilean context. Kindergartners in CLLIP classrooms had faster growth rates in letter naming, word reading, vocabulary, and phonemic segmentation fluency than those in control classrooms, and had higher scores at the end of the year in phonemic segmentation fluency, letter naming, and word reading. In addition, kindergartners from high SES families had faster growth rates than kindergartners from low SES families in letter naming and word reading. Effect sizes ranged from small (d = .18 in word reading) to fairly large (d = .70 in letter‐naming fluency). First‐grade students in CLLIP classrooms had faster growth rates than students in control classrooms in vocabulary, nonword reading fluency, word reading, and reading comprehension. Effect sizes were small in vocabulary, nonword reading fluency, and reading comprehension (.23 ≤ d ≤ .28) and medium in word reading (d = .50). These results suggest that the present multicomponent literacy instructional model had a positive impact on Chilean children's literacy acquisition.     

Home Literacy Environment and English Language and Literacy Skills Among Chinese Young Children Who Learn English as a Second Language

The present study explored the home literacy environment for Chinese ESL kindergarteners and examined the relationships between home literacy practices and language and literacy skills. Ninety Hong Kong Chinese ESL kindergarteners were assessed for English vocabulary, phonological awareness, letter knowledge and word reading. Their parents completed a questionnaire about home literacy practices. Results showed that these practices can be classified into three aspects: shared reading, exposure to English materials and home teaching. Shared reading uniquely predicted receptive and expressive vocabulary, syllable awareness and word reading in English. Exposure to English materials predicted expressive vocabulary and home teaching predicted letter knowledge.     

Private Speech in Illiterate Adults: Cognitive Functions, Task Difficulty, and Literacy

Children’s private speech has been widely studied among children, but it is clear that adults use private speech as well. In this study, illiterate adults’ private speech during a “school-like” task was explored as a function of literacy level and task difficulty in a sample of 126 adults enrolled in a public literacy program. A main effect for literacy level was found—private speech was more internalized and less externalized among adults with higher literacy levels. Externalized private speech was more frequently observed among illiterate adults engaged in the most difficult task. Private speech served cognitive functions as indicated by the proportion of self-regulatory private speech and the proportion of private speech preceding actions being higher in the advanced literacy group and among illiterate adults doing the easier task. Internalized private speech, self-regulatory private speech, and private speech preceding action were each positively correlated with performance and negatively correlated with time to complete the task. The use of private speech in illiterate adults appears to be linked to the mastery of cultural experiences, such as literacy, similar to the self-talk of children.     

Inhibitory control over no-longer-relevant information: Adult age differences

Hartman and Hasher (1991) used a garden-path task in which younger and older adults generated the final word for each of a series of high-cloze sentences. Under instructions to remember the final word, the experiment included critical sentences for which the generated word was replaced by a new, to-be-remembered target. Using an implicit priming task, the first experiment replicated a basic finding: Younger adults showed priming only for the target words, whereas older adults showed priming for both the generated and target words. Two experiments explored boundary conditions. One showed that an additional sentence that interpreted the new target word enabled older adults to narrow access to only the target word. The provision of additional time following the introduction of the new target word did not. Specific information, not more time, is required for inefficient inhibitory mechanisms to clear the recent past from memory.     

Bullying experiences and literacy achievement amongst primary school children

This study investigated the association between school bullying and literacy achievements in a sample of primary school children from Johannesburg, South Africa. The children (n?=?443; females?=?56%, males?=?44%) attending six primary schools in the Soweto area suburbs, self-reported their experience of bullying by peers. In addition, they completed tests of literacy. The results indicate that learners who self-reported being bullied performed poorly in literacy tests when compared to their peers, who were not subjected to bullying. In particular, those who experienced bullying scored lower on tasks that required literacy skills in phonics, spelling, and word choice. The findings indicate that learner support for school bullying survivors should aim to address the deleterious effects of bullying on literacy development.     

Mother–child joint writing in low SES: Sociocultural factors,maternal mediation,and emergent literacy

Emergent literacy was studied as related to sociocultural factors, particularly to maternal mediation of writing. Forty-one low socioeconomic status (SES) children, 5;5–6;0 years old, and their mothers participated. The child's emergent literacy was assessed by word writing and recognition, phonological awareness, and orthographic awareness. To assess mediation of writing, children were asked to write words and names, and their mothers were asked to help them. Maternal mediation was analyzed in terms of the steps in the encoding process that the mother intervened in, her reference to Hebrew orthography, and her mediation in printing letters. Child's literacy was found to be related to SES, maternal literacy, literacy tools at home, and maternal mediation. Hierarchical regressions indicated that child's literacy tools contributed to all emergent literacy skills, beyond SES and maternal literacy. The quality of mediation predicted word writing and recognition and phonological awareness after controlling for all sociocultural factors. A qualitative analysis illustrated the range of maternal mediation within or below the child's ZPD.     

Is Phonological Encoding in Naming Influenced by Literacy?

We examined phonological priming in illiterate adults, using a cross-modal picture-word interference task. Participants named pictures while hearing distractor words at different Stimulus Onset Asynchronies (SOAs). Ex-illiterates and university students were also tested. We specifically assessed the ability of the three populations to use fine-grained, phonemic units in phonological encoding of spoken words. In the phoneme-related condition, auditory words shared only the first phoneme with the target name. All participants named pictures faster with phoneme-related word distractors than with unrelated word distractors. The results thus show that phonemic representations intervene in phonological output processes independently of literacy. However, the phonemic priming effect was observed at a later SOA in illiterates compared to both ex-illiterates and university students. This may be attributed to differences in speed of picture identification.

本研究以义务教育阶段学生识字量测验为工具,综合运用探索性结构方程建模(ESEM)以及非参数项目反应理论中的摩根量表(Mokken量表)和DETECT分析方法,探讨了识字能力的维度。探索性结构方程建模结果显示,识字的单维性模型优于多维模型,多维的结果更多的体现出一个难度维度的特征,即字频的作用。Mokken量表分析结果显示,1~2年级和3~9年级测验更倾向于单维量表的特征。DETECT分析结果显示,两个测验的D值趋近于零,表明识字能力是单维能力。结合三种分析方法,识字能力具有单维性。     

Child sexual abuse and literacy achievement in a sample of South African primary school children

This study investigated child sexual abuse (CSA) and literacy achievement among South African primary school children. Data on self-reported experience of CSA and actual literacy achievement were collected from a convenience sample of 160 learners from a Soweto school in Johannesburg. The literacy tests measured five domains of reading and spelling competencies. The results show a statistically significant relationship between CSA and literacy scores, with learners who were sexually abused scoring significantly lower on the literacy tests used in this study. Specifically, learners with CSA experience performed noticeably lower in the real word test, followed by spelling, words spelt correctly, reading fluency, and non-word spelling. School psychologists could adopt a social justice framework in providing psychological and literacy support for children who are sexually abused.     

Lexical restructuring in the absence of literacy

Vocabulary growth was suggested to prompt the implementation of increasingly finer-grained lexical representations of spoken words in children (e.g., [Metsala, J. L., & Walley, A. C. (1998). Spoken vocabulary growth and the segmental restructuring of lexical representations: precursors to phonemic awareness and early reading ability. In J. L. Metsala & L. C. Ehri (Eds.), Word recognition in beginning literacy (pp. 89-120). Hillsdale, NJ: Erlbaum.]). Although literacy was not explicitly mentioned in this lexical restructuring hypothesis, the process of learning to read and spell might also have a significant impact on the specification of lexical representations (e.g., [Carroll, J. M., & Snowling, M. J. (2001). The effects of global similarity between stimuli on children’s judgments of rime and alliteration. Applied Psycholinguistics, 22, 327-342.]; [Goswami, U. (2000). Phonological representations, reading development and dyslexia: Towards a cross-linguistic theoretical framework. Dyslexia, 6, 133-151.]). This is what we checked in the present study. We manipulated word frequency and neighborhood density in a gating task (Experiment 1) and a word-identification-in-noise task (Experiment 2) presented to Portuguese literate and illiterate adults. Ex-illiterates were also tested in Experiment 2 in order to disentangle the effects of vocabulary size and literacy. There was an interaction between word frequency and neighborhood density, which was similar in the three groups. These did not differ even for the words that are supposed to undergo lexical restructuring the latest (low frequency words from sparse neighborhoods). Thus, segmental lexical representations seem to develop independently of literacy. While segmental restructuring is not affected by literacy, it constrains the development of phoneme awareness as shown by the fact that, in Experiment 3, neighborhood density modulated the phoneme deletion performance of both illiterates and ex-illiterates.     

Predicting children's word‐spelling difficulty for common English words from measures of orthographic transparency,phonemic and graphemic length and word frequency

Spencer demonstrated that spelling and reading difficulty for English words can be predicted from a number of factors, including word frequency, phonemic length and measures of orthographic depth and complexity. In this study, spelling difficulty of high frequency words was investigated across five year groups (ages 7 to 11 years) with a wide ranging series of data sources from which to determine word frequency values and orthographic depth measures. A regression model accounted for 52–66% of the variance for 7‐ to 11‐year‐olds and 72% of the variance for the lowest performing quartile group, irrespective of age. The most influential factor, phonetic difference (being the difference in the number of letters and phonemes in a word, and representing grapheme complexity), links the relative influence of large graphemic units in foundation literacy to a similar phenomenon, the ‘whammy’ effect, which provides support for serial processing in the dual route cascade model of word recognition in skilled readers ( Rastle & Coltheart, 1998 ). The study supports recent research on European orthographies, which concludes that both orthographic depth and complexity contribute to delayed acquisition of foundation literacy skills.     

Class size effects on literacy skills and literacy interest in first grade: A large-scale investigation

This article examines the impact of class size on literacy skills and on literacy interest in beginning readers from zones with specific educational needs in France. The data came from an experiment involving first graders in which teachers and pupils were randomly assigned to the different class types (small classes of 10-12 pupils vs. regular classes of 20-25 pupils).Globally, the findings reveal that class size has a (small) impact on the two basic literacy skills, reading (word recognition task) and spelling (word production task). Children with high literacy interest made more progress than children with low literacy interest. The analysis also explores the effect of four factors - early schooling, age, first language and socio-economic status - on the same type of literacy skills as above. Smaller classes most specifically improved performances in two types of population: children whose first language is French and children from intermediate and average socio-economic brackets. This means, in contrast, that neither the children from the most disadvantaged backgrounds nor the children whose first language was not French benefited from the use of smaller first grade classes. Data in this experiment are examined in the light of studies on the connections between class size, classroom procedures and pupils' engagement.
