EXPRESS: Contextual diversity and anchoring: Null effects on learning word forms and opposing effects on learning word meanings

Words that appear in many contexts/topics are recognised faster than those occurring in fewer contexts (Nation, 2017). However, contextual diversity benefits are less clear in word learning studies. Mak et al. (2021) proposed that diversity benefits might be enhanced if new word meanings are anchored before introducing diversity. In our study, adults (N = 288) learned meanings for eight pseudowords, four experienced in six topics (high diversity) and four in one topic (low diversity). All items were first experienced five times in one topic (anchoring phase), and results were compared to Norman et al. (2022) which used a similar paradigm without an anchoring phase. An old-new decision post-test (did you learn this word?) showed null effects of contextual diversity on written form recognition accuracy and response time, mirroring Norman et al.. A cloze task involved choosing which pseudoword completed a sentence. For sentences situated in a previously experienced context, accuracy was significantly higher for pseudowords learned in the low diversity condition, whereas for sentences situated in a new context, accuracy was non-significantly higher for pseudowords learned in the high diversity condition. Anchoring modulated these effects. Low diversity item accuracy was unaffected by anchoring. However, for high diversity items, accuracy in familiar contexts was better in the current experiment (anchoring) than in Norman et al. (non-anchoring), but accuracy in new contexts did not differ between the two experiments. These results suggest that anchoring facilitates meaning use in familiar contexts, but not generalisation to new contexts, nor word recognition in isolation.

Copy Skills and Writing Abilities in Children With and Without Specific Learning Disabilities

Copying a text quickly and accurately is important both in school and in daily life. However, this skill has never been systematically studied, either in children with typical development (TD) or in children with specific learning disabilities (SLD). The aim of this research was to study the features of a copy task and its relationship with other writing tasks. For this purpose, 674 children with TD and 65 children with SLD from Grades 6 through 8 in Italy were tested with a copy task and other writing assessment tasks, measuring three aspects of writing: handwriting speed, spelling, and expressive writing. Children with SLD performed worse on the copy task, both in terms of speed and accuracy, than children with TD. Copy speed was predicted by grade level and by all three major writing skills for children with TD but only by handwriting speed and spelling for children with SLD. Copy accuracy was predicted by gender and the three major writing skills for children with TD but only by spelling for children with SLD. These results suggest that children with SLD also have difficulty copying a text and benefit less than children with TD from their other writing skills.

The role of orthographic and phonological processing during reading Chinese sentences: Evidence from eye movements

The role of phonological and orthographic processing and their time course during lexical processing and sentence reading remain controversial. By adopting a misspelled-characters disruption paradigm and eye-tracking technique, we manipulated the writing for the first characters of two-character target words to investigate the relative role of orthographic and phonological processing on word recognition in Chinese reading. There are four conditions: (a) correct character, (b) misspelled character with a stroke missing, (c) misspelled homographic character, and (d) misspelled homophonic character. The results showed that homophonic errors caused more disruptions than other conditions in the early (first-pass reading times) and later (total reading time) stages of lexical processing during Chinese reading. Homographic errors and omitted stroke errors lead to equal disruptions at the early stage of word recognition, but homographic errors cause more disruptions at the later stage. These results suggest that orthography plays a dominant role in word recognition during Chinese reading, whereas phonology plays a weaker and more limited role. The direct access and dual-rote hypothesis may well explain the mechanism of lexical processing in Chinese reading.

Beyond the Visual Word Form Area - a cognitive characterization of the left ventral occipitotemporal cortex

The left ventral occipitotemporal cortex has been traditionally viewed as a pathway for visual object recognition including written letters and words. Its crucial role in reading was strengthened by the studies on the functionally localized "Visual Word Form Area" responsible for processing word-like information. However, in the past 20 years, empirical studies have challenged the assumptions of this brain region as processing exclusively visual or even orthographic stimuli. In this review, we aimed to present the development of understanding of the left ventral occipitotemporal cortex from the visually based letter area to the modality-independent symbolic language related region. We discuss theoretical and empirical research that includes orthographic, phonological, and semantic properties of language. Existing results showed that involvement of the left ventral occipitotemporal cortex is not limited to unimodal activity but also includes multimodal processes. The idea of the integrative nature of this region is supported by the broad functional and structural connectivity with language-related and attentional brain networks. We conclude that although the function of the area is not yet fully understood in human cognition, its role goes beyond visual word form processing. The left ventral occipitotemporal cortex seems to be crucial for combining higher-level language information with abstract forms that convey meaning independently of modality.

Modeling Item-Level Spelling Variance in Adults: Providing Further Insights into Lexical Quality

Purpose

The lexical quality (LQ) hypothesis predicts that a skilled reader's lexicon will be inhabited by a range of low- to high-quality items, and the probability of representing a word with high quality varies as a function of person-level, word-level, and item-specific variables. These predictions were tested with spelling accuracy as a gauge of LQ.

Method

Item-response based crossed random effects models explored simultaneous contributions of person-level (e.g., participant's decoding skill), word-level (e.g., word's transparency rating), item-specific (e.g., participant's familiarity with specific word), and person-by-word interaction predictors (e.g., decoding by transparency rating interaction) to the spelling of 25 commonly misspelled irregular English words in 61 undergraduate university students (M = 19.4 years, 70.49% female, 39.34% Hispanic, 81.97% White).

Results

Substantial variance among individuals in item-level spelling accuracy was accounted for by person-level decoding skill; item-specific familiarity, proportion of schwas correctly represented, and correctly identifying the word from its mispronunciation; and an interaction of transparency rating by general decoding skill.

Conclusions

Consistent with the LQ hypothesis, results suggest that one's ability to form a high-quality lexical representation of a given word depends on a complex combination of person-level abilities, word-level characteristics, item-specific experiences, and an interaction between person- and word-level influences.

Asymetric Event-Related Potential Priming Effects Between English Letters and American Sign Language Fingerspelling Fonts

Letter recognition plays an important role in reading and follows different phases of processing, from early visual feature detection to the access of abstract letter representations. Deaf ASL-English bilinguals experience orthography in two forms: English letters and fingerspelling. However, the neurobiological nature of fingerspelling representations, and the relationship between the two orthographies, remains unexplored. We examined the temporal dynamics of single English letter and ASL fingerspelling font processing in an unmasked priming paradigm with centrally presented targets for 200 ms preceded by 100 ms primes. Event-related brain potentials were recorded while participants performed a probe detection task. Experiment 1 examined English letter-to-letter priming in deaf signers and hearing non-signers. We found that English letter recognition is similar for deaf and hearing readers, extending previous findings with hearing readers to unmasked presentations. Experiment 2 examined priming effects between English letters and ASL fingerspelling fonts in deaf signers only. We found that fingerspelling fonts primed both fingerspelling fonts and English letters, but English letters did not prime fingerspelling fonts, indicating a priming asymmetry between letters and fingerspelling fonts. We also found an N400-like priming effect when the primes were fingerspelling fonts which might reflect strategic access to the lexical names of letters. The studies suggest that deaf ASL-English bilinguals process English letters and ASL fingerspelling differently and that the two systems may have distinct neural representations. However, the fact that fingerspelling fonts can prime English letters suggests that the two orthographies may share abstract representations to some extent.

Factors Affecting the Writing Performance in Hearing and Deaf Children: An Insight into Regularities and Irregularities of the Arabic Orthographic System

This study aims to account for the underlying causes of spelling errors in hearing and deaf children who speak a dialectal form of Arabic that substantially differs from the standard written one. It presents a general overview of the spoken Arabic language and its written system, drawing attention to some of the phonological and orthographic regularities and irregularities used in constructing and decoding Arabic words and sentences. It also accounts for the diglossic factors that interfere with the process of phoneme-to-grapheme mapping. The spelling outcomes of a group of hearing children are compared with another group of orally educated deaf children, who in addition to the complexity and diglossity of Arabic, have limited hearing abilities. Both groups performed two written tasks, one representing the standard form and the other representing the dialect. These tasks identified the types of spelling and segmentation errors and the effects of the committed errors on children's awareness of the concept of word and word boundaries. Analysis of the results reveals their spelling errors' nature and frequencies, and progressively categorizes the most prominent errors in practicing each language form. The deaf group (n = 30) produced significantly more errors than the hearing group (n = 36) in the dysphonetic errors and the word omission categories. The findings indicate that the sociolinguistic context of the Arabic language and the orthographic nature of the Arabic script are both important factors affecting hearing and deaf children's awareness of the concept of word as well as their spelling performance. These results may enable educators to understand the underlying factors of Arabic spelling and produce targeted error correction strategies to maximize children's learning outcomes.

The interaction of orthography, phonology and semantics in the process of second language learners' Chinese character production

Theories of connectionism emphasize the mappings of orthography, phonology, and semantics in the process of word recognition and production. Chinese has a logographic writing system, which is markedly different from alphabetic languages. The current study investigated how orthography, phonology, and semantics contribute to Chinese character production among Chinese as a second language (CSL) learners. This study collected 33,856 Chinese characters in a sample of 2,116 CSL learners with 7 diverse L1s. ANOVA was conducted to examine the effect of Chinese character error type on 7 L1s and three Chinese proficiency levels. The results of ANOVA revealed that successful CSL learners' Chinese character production was derived from connections between orthography, semantics, and phonology. Semantics, especially the orthography-semantics connection, was the key point for production skills. Furthermore, connectionist models of languages rather than language distance affected production. These findings indicate that Chinese character production is associated with not only orthographic knowledge but also representation mechanisms of orthography, phonology, and semantics between different language writing systems. The results contribute to a better understanding of literacy skills in CSL learners. Future research could further address how CSL learners transform perceptive skills into production skills and the correlation between reading and writing skills by examining and controlling other important cognitive variables.

Learning new words through reading: do robust spelling-sound mappings boost learning of word forms and meanings?

High-quality lexical representations depend on robust representations of written form (orthography), spoken form (phonology) and meaning (semantics), and strong bonds between them. Quality of lexical representations may be affected by amount of print exposure and the form of individual words. Words that are harder to decode (print-to-sound) may lead to fuzzy representations of the orthographic and phonological forms, potentially creating less stable foundations for semantic knowledge. These factors are difficult to disentangle in natural language research; in this registered report, we experimentally manipulated decoding ease and exposure at the item level. Adults read paragraphs describing invented meanings of pseudowords. Pseudowords appeared two or six times in a paragraph, and had easy (e.g. bamper) or hard (e.g. uzide) to decode spelling-sound mappings. Post-tests assessed word-form knowledge, orthography-semantic mappings and semantic-phonology mappings. Results showed that greater decoding ease improved learning of word forms and consequently also impacted on word meanings. Higher exposure frequency improved learning of word forms but not meanings. Exposure frequency also modulated the effect of decoding ease on word-form learning, with a stronger effect of decoding ease for fewer exposures. Disentangling effects of decoding ease from print exposure has important implications for understanding potential barriers to vocabulary learning.

Speaker Accent Modulates the Effects of Orthographic and Phonological Similarity on Auditory Processing by Learners of English

The cognate effect refers to translation equivalents with similar form between languages-i.e., cognates, such as "band" (English) and "banda" (Spanish)-being processed faster than words with dissimilar forms-such as, "cloud" and "nube." Substantive literature supports this claim, but is mostly based on orthographic similarity and tested in the visual modality. In a previous study, we found an inhibitory orthographic similarity effect in the auditory modality-i.e., greater orthographic similarity led to slower response times and reduced accuracy. The aim of the present study is to explain this effect. In doing so, we explore the role of the speaker's accent in auditory word recognition and whether native accents lead to a mismatch between the participants' phonological representation and the stimulus. Participants carried out a lexical decision task and a typing task in which they spelled out the word they heard. Words were produced by two speakers: one with a native English accent (Standard American) and the other with a non-native accent matching that of the participants (native Spanish speaker from Spain). We manipulated orthographic and phonological similarity orthogonally and found that accent did have some effect on both response time and accuracy as well as modulating the effects of similarity. Overall, the non-native accent improved performance, but it did not fully explain why high orthographic similarity items show an inhibitory effect in the auditory modality. Theoretical implications and future directions are discussed.

Semantic Versus Orthographic Preferences in Aphasia: Behavioral Evidence

In this study, we compared the orthographic and semantic preferences of healthy adults and age and gender matched adults with aphasia, an acquired language disorder. Previous research in word retrieval and word associations has addressed semantic and phonological connections, but it has not as often included analyses of orthographic skills. We matched (on age and gender) 10 neurotypical adults and 11 older adults with aphasia and administered to both groups a lexical discrimination task requiring them to select, from 18 choices, those words that were most different from three words (daughter, laughter, son). Among the choices were foil words (e.g., daughter), orthographic similarities (laughter) and semantic similarities (son). Results revealed that individuals with aphasia focused on orthographic differences, while healthy adults chose semantic differences. Further studies should further explore this orthographic focus to develop treatment strategies, using behavioral and objective measures, for word-finding deficits in aphasia.

Using Spelling Error Analyses to Examine Individual Differences in German Students From Diverse Linguistic Backgrounds: A Latent Class Approach

The current study examined German spelling errors among students with German as their first language (L1) and those with German as their second language (L2) in Grades 3-4 (elementary school students; n = 127) and Grades 5-7 (secondary school students; n = 379). Five hundred and six students participated in the study. We performed two separate latent class analyses on elementary and secondary school students. Results indicate that elementary school students can be categorized as good (Class 1), consonant error dominant (Class 2), or poor (Class 3) spellers. However, secondary students can be categorized as addition and sequence error dominant (Class 1), substitution and omission error dominant (Class 2), or poor (Class 3) spellers. The three-step multinomial logistic regression analyses suggested that decoding was associated with the highest chances of being poor spellers in both elementary and secondary schools. Speaking German as L1 or L2 was a significant predictor of heterogeneities in secondary, but not elementary, school students. Polish L1 secondary students had the highest possibility of being poor spellers. The results suggest heterogeneities of student profiles. In addition, special attention should be given to secondary school students with the Polish L1 background in their spelling struggles associated with German orthography.

English Spelling Performance in Writing Samples Among Spanish-Speaking ELLs

The depth of the English orthography makes reading and spelling in English a difficult task; particularly for English language learners (ELLs) whose first language (L1) has a shallow orthography. Mastering spelling in English is a critical component of increasing the English literacy of ELLs. This study investigated the English spelling of 569 Spanish-speaking ELLs in Grades 4 to 6. Participants' writing samples were analyzed for spelling errors. Latent class analysis was utilized to discover hidden categories within the data using eight spelling error categories: (a) Vowel Omission; (b) Vowel Addition; (c) Vowel Substitution; (d) Vowel Sequence; (e) Consonant Omission; (f) Consonant Addition; (g) Consonant Substitution; (h) Consonant Sequence. Consonant- and vowel-based errors were nearly equal in each grade level. Latent class analysis resulted in a two-class model. Students in Class 1 made more types of errors than students in Class 2. As the grade level increased, the percentage of students in Class 2 increased. The results of this study show the effects of English and Spanish orthographies on the spelling of Spanish-speaking ELLs, with spelling errors occurring among both vowels and consonants. As omissions were the most prevalent errors in both classes, spelling instruction aimed at decreasing omissions should be considered for ELLs.

International Perspectives on Spelling and Writing in Different Orthographies: Introduction to the Special Series

This article serves as an introduction to the special issue on spelling and writing in different orthographies. Most studies and theoretical models of writing are based on the English language, and it is generally assumed that what is true for English is also true for other languages. Further, there are more studies on reading compared to studies of writing and spelling. Considering that 80% of the world's population speaks a language other than English, we need more studies on writing and spelling in languages other than English. With this intention, we are presenting 6 papers on writing and spelling in different languages of different orthographic depth, from highly transparent orthographies like Spanish and Italian to highly opaque orthography like Cantonese.

Tonal and orthographic analysis in a Cantonese-speaking individual with nonfluent/agrammatic variant primary progressive aphasia

Clinical understanding of primary progressive aphasia (PPA) has been established based on English-speaking population. The lack of linguistic diversity in research hinders the diagnosis of PPA in non-English speaking patients. This case report describes the tonal and orthographic deficits of a multilingual native Cantonese-speaking woman with nonfluent/agrammatic variant PPA (nfvPPA) and progressive supranuclear palsy. Our findings suggest that Cantonese-speaking nfvPPA patients exhibit tone production impairments, tone perception deficits at the lexical selection processing, and linguistic dysgraphia errors unique to logographic script writer. These findings suggest that linguistic tailored approaches offer novel and effective tools in identifying non-English speaking PPA individuals.

Phonological precision for word recognition in skilled readers

According to the lexical quality hypothesis, differences in the orthographic, semantic, and phonological representations of words will affect individual reading performance. While several studies have focused on orthographic precision and semantic coherence, few have considered phonological precision. The present study used a suite of individual difference measures to assess which components of lexical quality contributed to competition resolution in a masked priming experiment. The experiment measured form priming for word and pseudoword targets with dense and sparse neighbourhoods in 84 university students. Individual difference measures of language and cognitive skills were also collected and a principal component analysis was used to group these data into components. The data showed that phonological precision and NHD interacted with form priming. In participants with high phonological precision, the direction of priming for word targets with sparse neighbourhoods was facilitatory, while the direction for those with dense neighbourhoods was inhibitory. In contrast, people with low phonological precision showed the opposite pattern, but the interaction was non-significant. These results suggest that the component of phonological precision is linked to lexical competition for word recognition and that access to the mental lexicon during reading is affected by differing levels of phonological processing.

Japanese orthographic complexity and speech duration in a reading task

The number of letters in a word's orthographic form can affect speech duration. Previous research in this area has been limited to studies of languages with alphabets. The current study expands upon this previous research by investigating effects on speech duration from units of orthographic complexity potentially analogous to letter length in Japanese, a language with a logography. In a modified version of a reading task used in one of the prior studies, native Japanese-speaking participants were audio-recorded reading pairs of homophonous words that varied by: 1) number of pen strokes in a single character; or 2) number of whole characters in their orthographic forms. Two-character words were produced significantly longer than one-character words. No significant effect was found from pen strokes on speech duration. These results are presented as evidence that the orthographic duration effect observed in previous studies is not limited to languages with alphabetic writing systems.

Does omitting the accent mark in a word affect sentence reading? Evidence from Spanish

Lexical stress in multisyllabic words is consistent in some languages (e.g., first syllable in Finnish), but it is variable in others (e.g., Spanish, English). To help lexical processing in a transparent language like Spanish, scholars have proposed a set of rules specifying which words require an accent mark indicating lexical stress in writing. However, recent word recognition using that lexical decision showed that word identification times were not affected by the omission of a word's accent mark in Spanish. To examine this question in a paradigm with greater ecological validity, we tested whether omitting the accent mark in a Spanish word had a deleterious effect during silent sentence reading. A target word was embedded in a sentence with its accent mark or not. Results showed no reading cost of omitting the word's accent mark in first-pass eye fixation durations, but we found a cost in the total reading time spent on the target word (i.e., including re-reading). Thus, the omission of an accent mark delays late, but not early, lexical processing in Spanish. These findings help constrain the locus of accent mark information in models of visual word recognition and reading. Furthermore, these findings offer some clues on how to simplify the Spanish rules of accentuation.

Effects of Orthographic Consistency on Bilingual Reading: Human and Computer Simulation Data

English serves as today’s lingua franca, a role not eased by the inconsistency of its orthography. Indeed, monolingual readers of more consistent orthographies such as Italian or German learn to read more quickly than monolingual English readers. Here, we assessed whether long-lasting bilingualism would mitigate orthography-specific differences in reading speed and whether the order in which orthographies with a different regularity are learned matters. We studied high-proficiency Italian-English and English-Italian bilinguals, with at least 20 years of intensive daily exposure to the second language and its orthography and we simulated sequential learning of the two orthographies with the CDP++ connectionist model of reading. We found that group differences in reading speed were comparatively bigger with Italian stimuli than with English stimuli. Furthermore, only Italian bilinguals took advantage of a blocked presentation of Italian stimuli compared to when stimuli from both languages were presented in mixed order, suggesting a greater ability to keep language-specific orthographic representations segregated. These findings demonstrate orthographic constraints on bilingual reading, whereby the level of consistency of the first learned orthography affects later learning and performance on a second orthography. The computer simulations were consistent with these conclusions.

Supporting Acquisition of Spelling Skills in Different Orthographies Using an Empirically Validated Digital Learning Environment

This paper discusses how the association learning principle works for supporting acquisition of basic spelling and reading skills using digital game-based learning environment with the Finland-based GraphoLearn (GL) technology. This program has been designed and validated to work with early readers of different alphabetic writing systems using repetition and reinforcing connections between spoken and written units. Initially GL was developed and found effective in training children at risk of reading disorders in Finland. Today GL training has been shown to support learning decoding skills among children independent of whether they face difficulties resulting from educational, social, or biological reasons.

On the tip of the pen: Effects of character-level lexical variables and handwriter-level individual differences on orthographic retrieval difficulties in Chinese handwriting

In the past few decades, Chinese speakers have suffered from difficulties in handwriting, which include tip-of-the-pen (TOP) states (knowing a character but failing to fully handwrite it) and character amnesia in general (a general inability to handwrite a character despite being able to recognise it). The current study presents a systematic empirical investigation of the effects of character-level lexical characteristics and handwriter-level individual differences on TOP, character amnesia, and partial orthographic access in TOP states. Using a spelling-to-dictation task, we had 64 participants to handwrite 200 simplified Chinese characters. We showed that, at the lexical level, participants experienced more TOP and character amnesia in handwriting if a character was less frequent, was acquired later in life, was embedded in a less familiar word, or had more strokes; TOP but not character amnesia was additionally affected by phonetic radical order and spelling regularity. At the handwriter level, people also experienced more TOP and character amnesia if they had more digital exposure, less pen exposure, or less print exposure. In a TOP state, partial orthographic access was more likely if a character was acquired later in life, had fewer strokes, or had a left-right or top-down composition or, if a handwriter had less digital exposure.

Brain Activity during Visual and Auditory Word Rhyming Tasks in Cantonese-Mandarin-English Trilinguals

It is unclear whether the brain activity during phonological processing of second languages (L2) is similar to that of the first language (L1) in trilingual individuals, especially when the L1 is logographic, and the L2s are logographic and alphabetic, respectively. To explore this issue, this study examined brain activity during visual and auditory word rhyming tasks in Cantonese–Mandarin–English trilinguals. Thirty Chinese college students whose L1 was Cantonese and L2s were Mandarin and English were recruited. Functional magnetic resonance imaging (fMRI) was conducted while subjects performed visual and auditory word rhyming tasks in three languages (Cantonese, Mandarin, and English). The results revealed that in Cantonese–Mandarin–English trilinguals, whose L1 is logographic and the orthography of their L2 is the same as L1—i.e., Mandarin and Cantonese, which share the same set of Chinese characters—the brain regions for the phonological processing of L2 are different from those of L1; when the orthography of L2 is quite different from L1, i.e., English and Cantonese who belong to different writing systems, the brain regions for the phonological processing of L2 are similar to those of L1. A significant interaction effect was observed between language and modality in bilateral lingual gyri. Regions of interest (ROI) analysis at lingual gyri revealed greater activation of this region when using English than Cantonese and Mandarin in visual tasks.

Orthographic and Phonological Processing in Chinese Character Copying - A Preliminary Report

In the current study, the effects of orthographic and phonological processing in Chinese character copying were investigated using a data set extracted from a database containing handwriting data of 856 stimuli; the responses of which were collected from 100 participants. To investigate the effect of character frequency, radical frequency, and phonetic regularity, 151 phonetic compounds were selected from the database because (1) their corresponding phonetic radicals were all free-standing characters, (2) their corresponding phonetic radicals were located at either the right or the bottom positions in the characters, and (3) no more than 10% of the participants made errors when copying these target characters. The results of the linear mixed effect models revealed that after controlling for inter-stroke distance (ISD) and stroke number, the inter-stroke intervals (ISIs) at the radical and logographeme boundaries were significantly longer, indicating significant orthographic processing in the immediate copying task that radicals and logographemes were used as writing units. In addition, shorter ISIs at the logographeme boundary associated with higher radical frequency, and shorter ISIs at the radical boundary associated with higher character frequency and regular characters, were observed. These observations indicated significant orthographic and phonological effects in the immediate copying task. Finally, the significant phonetic regularity effect observed also supported the notion that phonology contributes to Chinese character writing and that the effects of central processing, including character frequency and phonetic regularity, cascade over peripheral processing during Chinese character copying.

Neural Components of Reading Revealed by Distributed and Symbolic Computational Models

Determining how the cognitive components of reading - orthographic, phonological, and semantic representations - are instantiated in the brain has been a longstanding goal of psychology and human cognitive neuroscience. The two most prominent computational models of reading instantiate different cognitive processes, implying different neural processes. Artificial neural network (ANN) models of reading posit non-symbolic, distributed representations. The dual-route cascaded (DRC) model instead suggests two routes of processing, one representing symbolic rules of spelling-sound correspondence, the other representing orthographic and phonological lexicons. These models are not adjudicated by behavioral data and have never before been directly compared in terms of neural plausibility. We used representational similarity analysis to compare the predictions of these models to neural data from participants reading aloud. Both the ANN and DRC model representations corresponded with neural activity. However, ANN model representations correlated to more reading-relevant areas of cortex. When contributions from the DRC model were statistically controlled, partial correlations revealed that the ANN model accounted for significant variance in the neural data. The opposite analysis, examining the variance explained by the DRC model with contributions from the ANN model factored out, revealed no correspondence to neural activity. Our results suggest that ANNs trained using distributed representations provide a better correspondence between cognitive and neural coding. Additionally, this framework provides a principled approach for comparing computational models of cognitive function to gain insight into neural representations.

Learning to Spell in Arabic: The Impact of Script-Specific Visual-Orthographic Features

Learning to spell is a challenging process, especially for young learners, in part because it relies on multiple aspects of linguistic knowledge, primarily phonological and morphological. However, alongside these universals, there are significant writing system specifics, namely, language-specific and script-specific factors that may also challenge young readers and writers (Daniels and Share, 2018). The current study focuses on the impact of four distinctive visual-orthographic features of the Arabic abjad on spelling, namely, (i) the similarity of many basic letter-forms, (ii) allography (the positional variants of the letter forms), (iii) ligaturing (the joining of letters), and (iv) non-linearity (extra-linear diacritic-like signs used to mark consonantal, short vowel and morpho-syntactic distinctions). We examined the distribution of visual-orthographic spelling errors across three grade levels as well as the developmental changes in these errors. We predicted that these errors would account for a significant proportion of children's spelling errors. Ninety-six Arabic-speaking pupils from three elementary grades (1st, 2nd, 4th grades) were presented with a sequence of six pictures and asked to write a story or several sentences about the events depicted. All spelling errors were analyzed and categorized according to two types of categories: six visual-orthographic categories and six additional categories that relate to the more traditional error types (e.g., phonological). The results showed that the visual-orthographic category was the second most common error category across the three grade levels, accounting for over one quarter of all spelling errors. Ligaturing and letter shape formation errors emerged as the two most prevalent types of errors in this category. These findings clearly demonstrate that visual-orthographic features of the Arabic abjad pose significant challenges in learning to spell.

How do phonology and orthography feed back to influence syntactic encoding in language production? Evidence from structural priming in Mandarin

Do speakers make use of a word's phonological and orthographic forms to determine the syntactic structure of a sentence? We reported two Mandarin structural priming experiments involving homophones to investigate word-form feedback on syntactic encoding. Participants tended to reuse the syntactic structure across sentences; such a structural priming effect was enhanced when the prime and target sentences used homophone verbs (the homophone boost), regardless of whether the homophones were heterographic (homophones written in different character; Experiments 1 and 2) or homographic (homophones written in the same character; Experiment 2). Critically, the homophone boost was comparable between homographic and heterographic homophone primes (Experiment 2). Hence unlike phonology, orthography appears to play a minimal role in mediating structural priming in production. We suggest that the homophone boost results from lemma associations between homophones that develop due to phonological identity between homophones early during language learning; such associations stabilise before literacy acquisition, thus limiting the influence of orthographic identity on lemma association between homophones and in turn on structural priming in language production.

The Functional Neuroanatomy of Developmental Dyslexia Across Languages and Writing Systems

The present article reviews the literature on the functional neuroanatomy of developmental dyslexia across languages and writing systems. This includes comparisons of alphabetic languages differing in orthographic depth as well as comparisons across alphabetic, syllabic, and logographic writing systems. It provides a synthesis of the evidence for both universal and language-specific effects on dyslexic functional brain activation abnormalities during reading and reading-related tasks. Specifically, universal reading-related underactivation of dyslexic readers relative to typical readers is identified in core regions of the left hemisphere reading network including the occipito-temporal, temporo-parietal, and inferior frontal cortex. Orthography-specific dyslexic brain abnormalities are mainly related to the degree and spatial extent of under- and overactivation clusters. In addition, dyslexic structural gray matter abnormalities across languages and writing systems are analyzed. The neuroimaging findings are linked to the universal and orthography-dependent behavioral manifestations of developmental dyslexia. Finally, the present article provides insights into potential compensatory mechanisms that may support remediation across languages and writing systems.

Examining the neural and cognitive processes that underlie reading through naming speed tasks

We combined fMRI with eye tracking and speech recording to examine the neural and cognitive mechanisms that underlie reading. To simplify the study of the complex processes involved during reading, we used naming speed (NS) tasks (also known as rapid automatized naming or RAN) as a focus for this study, in which average reading right-handed adults named sets of stimuli (letters or objects) as quickly and accurately as possible. Due to the possibility of spoken output during fMRI studies creating motion artifacts, we employed both an overt session and a covert session. When comparing the two sessions, there were no significant differences in behavioral performance, sensorimotor activation (except for regions involved in the motor aspects of speech production) or activation in regions within the left-hemisphere-dominant neural reading network. This established that differences found between the tasks within the reading network were not attributed to speech production motion artifacts or sensorimotor processes. Both behavioral and neuroimaging measures showed that letter naming was a more automatic and efficient task than object naming. Furthermore, specific manipulations to the NS tasks to make the stimuli more visually and/or phonologically similar differentially activated the reading network in the left hemisphere associated with phonological, orthographic and orthographic-to-phonological processing, but not articulatory/motor processing related to speech production. These findings further our understanding of the underlying neural processes that support reading by examining how activation within the reading network differs with both task performance and task characteristics.

The Clock Counts - Length Effects in English Dyslexic Readers

In reading, length effects (LEs) are defined as an increment in the time taken to read as a function of word length and may indicate whether reading is proceeding in an efficient whole word fashion or by serial letter processing. LEs are generally considered to be a pathognomonic symptom of developmental dyslexia (DD) and predominantly have been investigated in transparent orthographies where reading impairment is characterized as slow and effortful. In the present study a sample of 18 adult participants with DD were compared to a matched sample of typical developing readers to investigate whether the LE is a critical aspect of DD in an opaque orthography, English. We expected that the DD group would present with marked LEs, in both words and non-words, compared to typical developing readers. The presence of LEs in the DD group confirmed our prediction. These effects were particularly strong in low frequency words and in non-words, as observed in reading speed. These preliminary findings may have important theoretical implications for current understanding of DD.

Neural Effects of Gender and Age Interact in Reading

There has been an enduring fascination with the possibility of gender differences in the brain basis of language, yet the evidence has been largely equivocal. Evidence does exist, however, for women being at greater risk than men for developing psychomotor slowing and even Alzheimer disease with advancing age, although this may in part at least be due to women living longer. We examined whether gender, age, or their interaction influenced language-related or more general processes in reading. Reading consists of elements related to language, such as the processing of word sound patterns (phonology) and meanings (semantics), along with the lead-in processes of visual perception and orthographic (visual word form) processing that are specific to reading. To test for any influence of gender and age on either semantic processing or orthography-phonology mapping, we tested for an interaction of these factors on differences between meaningful words and meaningless but pronounceable non-words. We also tested for effects of gender and age on how the number of letters in a word modulates neural activity for reading. This lead-in process presumably relates most to orthography. Behaviorally, reading accuracy declined with age for both men and women, but the decline was steeper for men. Neurally, interactions between gender and age were found exclusively in medial orbitofrontal cortex (mOFC). These factors influenced the word-non-word contrast, but not the parametric effect of number of letters. Men showed increasing activation with age for non-words compared to words. Women showed only slightly decreasing activation with age for novel letter strings. Overall, we found interactive effects of gender and age in the mOFC on the left primarily for novel letter strings, but no such interaction for a contrast that emphasized visual form processing. Thus the interaction of gender with age in the mOFC may relate most to orthography-phonology conversion for unfamiliar letter strings. More generally, this suggests that efforts to investigate effects of gender on language-related tasks may benefit from taking into account age and the type of cognitive process being highlighted.

Auditory-orthographic integration at the onset of L2 speech acquisition

Recent studies have provided evidence for both a positive and a negative effect of orthography on second language speech learning. However, not much is known about whether orthography can trigger a McGurk-like effect (McGurk & MacDonald, 1976) in second language speech learning. This study examined whether exposure to auditory and orthographic input may lead to a McGurk-like effect in naïve English-speaking participants learning a second language with Spanish phonology and orthography. Specifically, it reports on (a) production of non-target-like combinations such as [lj] as in [poljo] for <pollo>-[pojo], where the auditory Spanish [j] and the first language English [l] that correspond to the shared digraph <ll> are integrated, and (b) fusion quantified in terms of [z] devoicing such as [z̥apito] for <zapito>-[zapito]. Moreover, the effects of (a) type of grapheme-to-sound correspondence, (b) position in the word, and (c) condition of training and testing were examined. Participants were assigned to four groups: (a) auditory only, (b) orthography at training and production, (c) orthography at training, and (d) orthography at production. The positions included word-initial and word-medial. The grapheme-to-sound correspondences consisted of <v>-[b], <d>-[δ], <z>-[s] and <ll>-[j]. Results were indicative of a McGurk-like effect only for the Spanish digraph <ll>. The highest rate of combination productions was attested in the orthography-training condition in the word-medial position.

Mapping visual symbols onto spoken language along the ventral visual stream

Learning to read is the most important milestone in a child’s education. However, controversies remain regarding how readers’ brains transform written words into sounds and meanings. We address these by combining artificial language learning with neuroimaging to reveal how the brain represents written words. Participants learned to read new words written in 2 different alphabets. Following 2 wk of training, we found a hierarchy of brain areas that support reading. Letter position is represented more flexibly from lower to higher visual regions. Furthermore, higher visual regions encode information about word sounds and meanings. These findings advance our understanding of how the brain comprehends language from arbitrary visual symbols.

Reading involves transforming arbitrary visual symbols into sounds and meanings. This study interrogated the neural representations in ventral occipitotemporal cortex (vOT) that support this transformation process. Twenty-four adults learned to read 2 sets of 24 novel words that shared phonemes and semantic categories but were written in different artificial orthographies. Following 2 wk of training, participants read the trained words while neural activity was measured with functional MRI. Representational similarity analysis on item pairs from the same orthography revealed that right vOT and posterior regions of left vOT were sensitive to basic visual similarity. Left vOT encoded letter identity and representations became more invariant to position along a posterior-to-anterior hierarchy. Item pairs that shared sounds or meanings, but were written in different orthographies with no letters in common, evoked similar neural patterns in anterior left vOT. These results reveal a hierarchical, posterior-to-anterior gradient in vOT, in which representations of letters become increasingly invariant to position and are transformed to convey spoken language information.

The Changing Role of Phonology in Reading Development

Processing of both a word's orthography (its printed form) and phonology (its associated speech sounds) are critical for lexical identification during reading, both in beginning and skilled readers. Theories of learning to read typically posit a developmental change, from early readers' reliance on phonology to more skilled readers' development of direct orthographic-semantic links. Specifically, in becoming a skilled reader, the extent to which an individual processes phonology during lexical identification is thought to decrease. Recent data from eye movement research suggests, however, that the developmental change in phonological processing is somewhat more nuanced than this. Such studies show that phonology influences lexical identification in beginning and skilled readers in both typically and atypically developing populations. These data indicate, therefore, that the developmental change might better be characterised as a transition from overt decoding to abstract, covert recoding. We do not stop processing phonology as we become more skilled at reading; rather, the nature of that processing changes.

The use of Greek and Latin prepositions and prefixes in compound names: proposed emendation of Appendix 9 of the International Code of Nomenclature of Prokaryotes

Part A of Appendix 9 - Orthography of the International Code of Nomenclature of Prokaryotes regulates the formation of compound generic names and specific epithets derived by combining two or more words or word elements of Latin and/or Greek origin, using the word stems and connecting vowels (-o- or -i-) following word elements derived from Greek and Latin, respectively. The rules given and the exceptions listed are suitable for substantives (nouns) and adjectives used as word elements, but not for prepositions and prefixes. Therefore, we propose a non-retroactive modification of Appendix 9 so that the guidelines given in Part A apply only to compound names that include a noun or an adjective in a non-final position. We also propose guidelines for the proper use of Greek and Latin prepositions, prefixes and adverbs in compound names in which the following word element starts with a vowel.

Writing Before Speaking Modifies Speech Production

We investigated whether orthographic information influences speech production. We used a non-color-word version of the Stroop task in which participants had to ignore the presented words but name their ink color instead. In two experiments, we manipulated the phonological and orthographic relationships between the words and their ink color and the tasks' context by preactivating or not orthographic information. The relation between the first letter of the prime word and the first phoneme of the color name was phonological or orthographic and phonological or unrelated. In Experiment 1, only phonological information carried out by the prime word affected spoken naming; orthographic information did not help. In Experiment 2, speech production was influenced by orthographic information only after an initial writing task. This confirms that orthographic information can support speaking and that speech is sensitive to properties of the task's context, suggesting that orthographic information is coactivated online with phonological information.

Reading Pinyin activates sublexcial character orthography for skilled Chinese readers

How do skilled Chinese readers, accustomed to characters, process Pinyin, a phonemic transcription of Chinese? Does the orthography of Chinese characters become activated? In four experiments, native speakers first made a meaning judgment on a two-syllable word written in Pinyin. Immediately following, they responded to a character whose orthography sometimes was related to the character corresponding to the Pinyin. In Experiments 1 and 3, participant named the color of the presented characters; there was an interference effect when the presented characters included phonetic radicals that were part of the character corresponding to the Pinyin. In Experiments 2 and 4, participants named the character; naming times were affected if either the semantic or phonetic radical was shared with the character corresponding to the Pinyin. The results indicate that access to lexical representations in Chinese is centered on the orthographic character, even when the input is Pinyin.

What Methods of Scoring Young Children's Spelling Best Predict Later Spelling Performance?

BACKGROUND

Children's spellings are often scored as correct or incorrect, but other measures may be better predictors of later spelling performance.

METHOD

We examined seven measures of spelling in Reception Year and Year 1 (5-6 years old) as predictors of performance on a standardized spelling test in Year 2 (age 7).

RESULTS

Correctness was the best predictor of later spelling by the middle of Year 1, and it significantly outperformed a binary measure of phonological plausibility at the end of Reception Year. Nonbinary measures based on Levenshtein distance were significant predictors of later spelling in the middle of Reception Year and in children who produced no correct spellings. Some widely used scales performed less well with children who did not yet produce any correct spellings.

CONCLUSIONS

Nonbinary measures of spelling performance can predict later spelling performance, but for a more restricted period than anticipated based on many theories.

The Effect of Orthography on the Lexical Encoding of Palatalized Consonants in L2 Russian

The current study investigated the potential facilitative or inhibiting effects of orthography on the lexical encoding of palatalized consonants in L2 Russian. We hypothesized that learners with stable knowledge of orthographic and metalinguistic representations of palatalized consonants would display more accurate lexical encoding of the plain/palatalized contrast. The participants of the study were 40 American learners of Russian. Ten Russian native speakers served as a control group. The materials of the study comprised 20 real words, familiar to the participants, with target coronal consonants alternating in word-final and intervocalic positions. The participants performed three tasks: written picture naming, metalinguistic, and auditory word-picture matching. Results showed that learners were not entirely familiar with the grapheme-phoneme correspondences in L2 Russian. Even though they spelled almost all of these familiar Russian words accurately, they were able to identify the plain/palatalized status of the target consonants in these words with about 80% accuracy on a metalinguistic task. The effect of orthography on the lexical encoding was found to be dependent on the syllable position of the target consonants. In intervocalic position, learners erroneously relied on vowels following the target consonants rather than the consonants themselves to encode words with plain/palatalized consonants. In word-final position, although learners possessed the orthographic and metalinguistic knowledge of the difference in the palatalization status of the target consonants-and hence had established some aspects of the lexical representations for the words-those representations appeared to lack in phonological granularity and detail, perhaps due to the lack of perceptual salience.

Introduction to the Special Issue: Learning to Listen from Sounds to Words

The eight articles in this special issue 'Learning to listen from sounds to words' were presented at the conference Sound to Word in Bilingual and Second Language Speech Perception held at the University of Iowa in spring 2016. The selected contributions focus on how second language speech perception interacts with orthography, how phonology interacts with speech perception and how listeners use the cues in the input to segment and create the word forms for lexical processing. This collection of papers expands the field of speech perception and production by granting a central role to the lexicon and exploring how listeners and speakers activate representations, from sounds to words.

A Picture Is Worth… Both Spelling and Sound

In an event-related potential (ERP) study using picture stimuli, we explored whether spelling information is co-activated with sound information even when neither type of information is explicitly provided. Pairs of picture stimuli presented in a rhyming paradigm were varied by both phonology (the two images in a pair had either rhyming, e.g., boat and goat, or non-rhyming, e.g., boat and cane, labels) and orthography (rhyming image pairs had labels that were either spelled the same, e.g., boat and goat, or not spelled the same, e.g., brain and cane). Electrophysiological picture rhyming (sound) effects were evident in terms of both N400/N450 and late effect amplitude: Non-rhyming images elicited more negative waves than rhyming images. Remarkably, the magnitude of the late ERP rhyming effect was modulated by spelling - even though words were neither explicitly seen nor heard during the task. Moreover, both the N400/N450 and late rhyming effects in the spelled-the-same (orthographically matched) condition were larger in the group with higher scores (by median split) on a standardized measure of sound awareness. Overall, the findings show concomitant meaning (semantic), sound (phonological), and spelling (orthographic) activation for picture processing in a rhyming paradigm, especially in young adults with better reading skills. Not outwardly lexical but nonetheless modulated by reading skill, electrophysiological picture rhyming effects may be useful for exploring co-activation in children with dyslexia.

The processing of inflected and derived words in writing

We report on an English-speaking, aphasic individual (RB) with a spelling deficit more severely affecting orthographically irregular words for which phonologically plausible errors (PPEs) were produced. PPEs were observed for all word forms, with the exception of inflectional suffixes, despite the irregular sound-print mappings of many inflectional suffixes (e.g., walked → /wɔkt/). RB's pattern replicates that reported in Badecker, Rapp, and Caramazza (Badecker, W., Rapp, B., & Caramazza, A. (1996). Lexical Morphology and the Two Orthographic Routes. Cognitive Neuropsychology, 13, 161-176). We extended their investigation by examining RB's spelling of derived words and found a selective deficit for derived words compared to inflected words in writing. This selective deficit did not appear to reflect differences in morphological transparency or suffix frequencies that exist between inflection and derivation. This is the first evidence that distinct neural mechanisms support inflection and derivation in spelling.

How modality-specific is morphology?

Writing has long been considered to be dependent on speaking. However, modality-specific dissociations between written and spoken word production imply that word production is supported by distinct neural mechanisms in writing, which can be impaired or spared regardless of the intactness of spoken word production. Rapp et al. (2015). Modality and morphology: What we write may not be what we say. Psychological Science, 26, 892-902 documented a double dissociation where problems with regular inflections were selectively restricted to writing or speaking. We report on two English-speaking aphasic individuals who exhibit this same modality-specific dissociation of inflectional processing, replicating the original findings. We expand on Rapp et al.'s study by examining whether the dissociations observed with regular inflections extend to other morphological forms, such as derivation and irregular inflection. Results showed that the dissociation holds for derivation; however, both participants were impaired with irregular inflections in both output modalities. Implications of these findings for morphological processing and the independence of the orthographic system are discussed.

Information properties of morphologically complex words modulate brain activity during word reading

Neuroimaging studies of the reading process point to functionally distinct stages in word recognition. Yet, current understanding of the operations linked to those various stages is mainly descriptive in nature. Approaches developed in the field of computational linguistics may offer a more quantitative approach for understanding brain dynamics. Our aim was to evaluate whether a statistical model of morphology, with well‐defined computational principles, can capture the neural dynamics of reading, using the concept of surprisal from information theory as the common measure. The Morfessor model, created for unsupervised discovery of morphemes, is based on the minimum description length principle and attempts to find optimal units of representation for complex words. In a word recognition task, we correlated brain responses to word surprisal values derived from Morfessor and from other psycholinguistic variables that have been linked with various levels of linguistic abstraction. The magnetoencephalography data analysis focused on spatially, temporally and functionally distinct components of cortical activation observed in reading tasks. The early occipital and occipito‐temporal responses were correlated with parameters relating to visual complexity and orthographic properties, whereas the later bilateral superior temporal activation was correlated with whole‐word based and morphological models. The results show that the word processing costs estimated by the statistical Morfessor model are relevant for brain dynamics of reading during late processing stages.

What causes the greater perceived similarity of consonant-transposed nonwords?

Nonwords created by transposing two non-adjacent orthographic consonants (CONDISER) have been reported to produce more priming for their baseword (CONSIDER), and to be classified as a nonword less readily than nonwords created by transposing two orthographic vowels (CINSODER). We investigate the origin of this difference and its relevance for theories of letter position coding. In the unprimed versions of the lexical decision and same-different tasks, a consonant-vowel difference was found in the transposition condition, not when those letters are substituted (Experiment 1). We found that when transpositions involved the disruption of a consonant cluster (OPMITAL), reaction times were slowed compared to when transpositions involved only letters that are separated (CHOLOCATE; Experiment 2). As transpositions more frequently disrupt in consonant clusters than vowel clusters, this introduces a confound in studies investigating consonant and vowel transposition effects. Consistent with the idea that letter order is harder to resolve in clusters, the difference between consonants and vowels was eliminated when transpositions involve singleton consonants or vowels rather than those in clusters (Experiment 3). These results suggest that the precision of position coding does not differ between consonants and vowels, but that consonant-vowel status plays a role in structuring orthographic representations.

ERPs reveal weaker effects of spelling on auditory rhyme decisions in children than in adults

A classic finding in psycholinguistics is that orthographic form influences the processing of auditory words. The aim of the present study was to examine how reading experience changes this effect. Specifically, we tested the prediction that top-down visual modulation of spoken word recognition is reduced in children compared to adults, owing to their reduced experience with print. Event-related potentials (ERPs) were measured as 8-10-year-old children and adults made rhyme decisions about spoken word pairs that were either orthographically similar or dissimilar. When orthography did not conflict (e.g., throat-boat), both age groups demonstrated a robust rhyme effect marked by greater N400 to no-rhyme versus rhyme trials. For rhyming trials that differed in orthography (e.g., vote-boat) and non-rhyming trials that shared orthography (e.g., warm-farm), adults showed more interference than children. Differences in orthographic interference suggest an extended developmental schedule for top-down mechanisms in speech recognition.

Differences between child and adult large-scale functional brain networks for reading tasks

Reading is an important high-level cognitive function of the human brain, requiring interaction among multiple brain regions. Revealing differences between children's large-scale functional brain networks for reading tasks and those of adults helps us to understand how the functional network changes over reading development. Here we used functional magnetic resonance imaging data of 17 adults (19-28 years old) and 16 children (11-13 years old), and graph theoretical analyses to investigate age-related changes in large-scale functional networks during rhyming and meaning judgment tasks on pairs of visually presented Chinese characters. We found that: (1) adults had stronger inter-regional connectivity and nodal degree in occipital regions, while children had stronger inter-regional connectivity in temporal regions, suggesting that adults rely more on visual orthographic processing whereas children rely more on auditory phonological processing during reading. (2) Only adults showed between-task differences in inter-regional connectivity and nodal degree, whereas children showed no task differences, suggesting the topological organization of adults' reading network is more specialized. (3) Children showed greater inter-regional connectivity and nodal degree than adults in multiple subcortical regions; the hubs in children were more distributed in subcortical regions while the hubs in adults were more distributed in cortical regions. These findings suggest that reading development is manifested by a shift from reliance on subcortical to cortical regions. Taken together, our study suggests that Chinese reading development is supported by developmental changes in brain connectivity properties, and some of these changes may be domain-general while others may be specific to the reading domain.

Morpheme-based Reading and Spelling in Italian Children with Developmental Dyslexia and Dysorthography

Italian sixth graders, with and without dyslexia, read pseudowords and low-frequency words that include high-frequency morphemes better than stimuli not including any morpheme. The present study assessed whether morphemes affect (1) younger children, with and without dyslexia; (2) spelling as well as reading; and (3) words with low-frequency morphemes. Two groups of third graders (16 children with dyslexia and dysorthography and 16 age-matched typically developing children) read aloud and spelt to dictation pseudowords and words. Pseudowords included (1) root + suffix in not existing combinations (e.g. lampadista, formed by lampad-, 'lamp', and -ista, '-ist') and (2) orthographic sequences not corresponding to any Italian root or suffix (e.g. livonosto). Words had low frequency and included: (1) root + suffix, both of high frequency (e.g. bestiale, 'beastly'); (2) root + suffix, both of low frequency (e.g. asprigno, 'rather sour'); and (3) simple words (e.g. insulso, 'vapid'). Children with dyslexia and dysorthography were less accurate than typically developing children. Root + suffix pseudowords were read and spelt more accurately than non-morphological pseudowords by both groups. Morphologically complex (root + suffix) words were read and spelt better than simple words. However, task interacted with morphology: reading was not facilitated by low-frequency morphemes. We conclude that children acquiring a transparent orthography exploit morpheme-based reading and spelling to face difficulties in processing long unfamiliar stimuli.

Development of the Visual Word Form Area Requires Visual Experience: Evidence from Blind Braille Readers

Learning to read causes the development of a letter- and word-selective region known as the visual word form area (VWFA) within the human ventral visual object stream. Why does a reading-selective region develop at this anatomical location? According to one hypothesis, the VWFA develops at the nexus of visual inputs from retinotopic cortices and linguistic input from the frontotemporal language network because reading involves extracting linguistic information from visual symbols. Surprisingly, the anatomical location of the VWFA is also active when blind individuals read Braille by touch, suggesting that vision is not required for the development of the VWFA. In this study, we tested the alternative prediction that VWFA development is in fact influenced by visual experience. We predicted that in the absence of vision, the "VWFA" is incorporated into the frontotemporal language network and participates in high-level language processing. Congenitally blind (n = 10, 9 female, 1 male) and sighted control (n = 15, 9 female, 6 male), male and female participants each took part in two functional magnetic resonance imaging experiments: (1) word reading (Braille for blind and print for sighted participants), and (2) listening to spoken sentences of different grammatical complexity (both groups). We find that in blind, but not sighted participants, the anatomical location of the VWFA responds both to written words and to the grammatical complexity of spoken sentences. This suggests that in blindness, this region takes on high-level linguistic functions, becoming less selective for reading. More generally, the current findings suggest that experience during development has a major effect on functional specialization in the human cortex.SIGNIFICANCE STATEMENT The visual word form area (VWFA) is a region in the human cortex that becomes specialized for the recognition of written letters and words. Why does this particular brain region become specialized for reading? We tested the hypothesis that the VWFA develops within the ventral visual stream because reading involves extracting linguistic information from visual symbols. Consistent with this hypothesis, we find that in congenitally blind Braille readers, but not sighted readers of print, the VWFA region is active during grammatical processing of spoken sentences. These results suggest that visual experience contributes to VWFA specialization, and that different neural implementations of reading are possible.

Models of Reading in Different Orthographies: An Introduction

The authors provide a summary of the articles in the special series on reading development in different orthographies from various writing systems and scripts.

Learning to Read a Semitic Abjad: The Triplex Model of Hebrew Reading Development

We introduce a model of Hebrew reading development that emphasizes both the universal and script-specific aspects of learning to read a Semitic abjad. At the universal level, the study of Hebrew reading acquisition offers valuable insights into the fundamental dilemmas of all writing systems-balancing the competing needs of the novice versus the expert reader (Share, 2008). At the script-specific level, pointed Hebrew initially employs supplementary vowel signs, providing the beginning reader a consistent, phonologically well-specified script while helping the expert-to-be unitize words and morphemes via (consonantal) spelling constancy. A major challenge for the developing Hebrew reader is negotiating the transition from pointed to unpointed Hebrew, with its abundance of homographs. Our triplex model emphasizes three phases of early Hebrew reading development: a progression from lower-order, phonological (sublexical) sequential spelling-to-sound translation (Phase 1, Grade 1) to higher-order, string-level (lexical) lexico-morpho-orthographic processing (Phase 2, Grade 2) followed, in the upper elementary grades, by a supralexical contextual level (Phase 3) essential for dealing with the pervasive homography of unpointed Hebrew.
