Background: The expressiveness during reading is essential for a fluent reading. Reading prosody has been scarcely studied in an experimental manner, owing to the difficulties in taking objective and direct measures of this reading skill. However, new technologies development has made it possible to analyse reading prosody in an experimental way. Prosodic patterns may vary, not being the same at the beginning of the reading learning process as in adulthood. They may also be altered in disorders such as dyslexia, but little is known about the prosodic characteristics and reading fluency of people with neurodegenerative diseases that cause language impairment, such as Parkinson's disease (PD). Aims: The aim of this work was to study reading fluency in PD considering the prosodic characteristics of its reading. Methods & Procedures: The participants were 31 Spanish adults with PD and 31 healthy controls, aged 59-88 years. Two experimental texts were designed that included declarative, interrogative, and exclamatory sentences and experimental verbs and nouns. The manipulability level of the nouns and the motor content of the verbs were considered. The reading of the participants was recorded and analysed with Praat software. Outcomes & Results: A longer reading duration and a greater number of pauses, especially in verbs, were found in the PD group, which also showed less pitch variation than the control group in the experimental sentences. The control group showed a big initial rise in declarative and interrogative sentences, as well as a stronger final declination in declarative and exclamatory ones, when compared to the PD group. Conclusions & Implications: The use of experimental methodologies for the analysis of reading fluency allows learning more about the prosodic characteristics of people with different pathologies, such as PD. Scarce pitch variability found in the analysis, together with the great number of pauses and the longer reading duration, leads to poorly expressive reading, which compromises fluency in PD. The exhaustive evaluation of the reading fluency of PD patients will make it possible to design more complete assessment methods that will favour the diagnosis and early detection of this pathology.

Recent research has stated that early oral language acquisition difficulties are related to reading and writing difficulties. Children with developmental language disorder (DLD) experience difficulties with several dimensions of language. In this study we focus on the specific difficulties of children with DLD in spelling. We examine the impact of lexicality and length in written production of Spanish-speaking children with DLD. A total of 18 children with language difficulties (M[subscript age] = 8;4) were compared with age-matched children (M[subscript age] = 8;2). Participants completed a spelling-to-dictation task of words and pseudo-words, where length was manipulated. A digital tablet was used to collect data and obtain measures of accuracy, latencies and total writing durations. Results showed that children with DLD produced more errors, longer latencies and longer writing durations than age-matched children. Regarding accuracy, analysis of the errors shows that children in the control group produce few errors, most being substitutions, while children with DLD made more errors and of more varied categories. Moreover, they were more affected by length on writing accuracy than the control group.

It is common to see mirror errors in letters in early stages of reading due to the mirror-generalization process that allows a visual stimulus to be identified independently of its orientation. To avoid such errors, this process must be inhibited. A special case would be children with dyslexia since their difficulties with the alphabetic code may also delay the acquisition of correct letter orientation. We investigated the relationship between reversible errors in reading and dyslexia. Twenty-seven Spanish-speaking children with dyslexia (7-12 years old) and 27 chronological-age-matched controls performed a 'same-different' letter decision task on reversible and non-reversible letters. Results showed that all participants required more time and committed more errors in discriminating reversible letters. In addition, worse execution was observed in the dyslexic group, which seems to indicate that this group is delayed in the acquisition of correct letter orientation. Therefore, our results indicated that overcoming reading errors in mirrors depends to some extent on the reading competence of the children and the ability to inhibit the process of generalization of mirrors.

Spelling and handwriting are different processes; however, they are learned simultaneously, and numerous studies have shown that they interact. Besides the commonly reported presence of a spelling deficit, previous studies have indicated that handwriting difficulties can also be detected in children with dyslexia. Despite this, this issue has not been sufficiently explored. The goal of the study was to investigate the potential handwriting difficulties met by children with dyslexia and how they might relate to spelling difficulties and to basic graphic skills. Twenty children with dyslexia were compared with a chronological age-matched group and reading level-matched group. Participants completed a spelling-to-dictation task of words and pseudowords, an alphabet writing task, and two graphic tasks. Results showed that children with dyslexia were less accurate and slower in preparing and executing the written response than typically developing peers, but they showed the spelling level expected given their reading ability. Children with dyslexia also performed similarly to children with the same reading level in the alphabet and graphic tasks, with both groups being slower and less fluent than the control age group. Altogether, the results suggest the existence of a delay in the development of handwriting and graphic fluency related to the level of reading and spelling skills rather than the presence of a core deficit affecting fine motor skills in dyslexia. In this sense, it seems that reduced literacy skills can affect the development of other skills that are usually enhanced with handwriting practice, such as fine motor skills.

This study explores the time-course of word processing by grammatical class (verbs vs. nouns) and meaning (action vs. non-action) by means of an ERP experiment. The morphology of Spanish words allows for a noun (e.g., "bail"-e [a dance]) or a verb (e.g., "bail"-ar [to dance]) to be formed by simply changing the suffix attached to the root. This facility results in a set of nouns and verbs that are nearly matched in meaning, because of their shared root. The results show that grammatical class of words is processed very early, around 200 ms after the word onset, with the effects remaining activated at left frontal regions until 800 ms. Later components show a focal LAN sensitive to the noun-verb distinction, and a broadly distributed N400-like waveform sensitive to meaning. The different components affected by grammar (P200 and LAN) and meaning (N400) and their topographical dissimilarity seem to indicate an independent neural processing of these two linguistic properties and support a lexical specification of grammatical class.

Background: Prosodic reading is one of the steps needed to achieve reading fluency. It is already known that English children develop their reading prosody from the earliest grades of primary school, showing the greatest improvement between first and second grade, but there are no Spanish studies of the development of reading prosody in the first years of school. Reading prosody may develop earlier in Spanish children as Spanish is a transparent language, which makes it possible to achieve high accuracy in the first year of learning to read. Method: We performed a longitudinal study, monitoring children from first to third grade. The children were asked to read aloud a text including declarative sentences containing high-frequency and low-frequency words and interrogative sentences; we analysed the usual prosodic variables (i.e., pauses, duration of different segments and pitch variations). Results: The results showed that younger readers made more and longer pauses and read less accurately. Moreover, the frequency words affected accuracy in all three grades, but only modified reading time in the first and second grades. We found no differences between the grades with respect to declarative sentences, but reading in all grades was influenced by word frequency, with a flatter final intonation. In the case of interrogative sentences, we found that first graders had a flatter melodic contour, whereas second graders tended to exaggerate the final change in intonation. Conclusions: Our results confirmed that reading fluency increases dramatically between first and second grade. Although Spanish has a transparent orthographic system, Spanish children seem to develop reading prosody similarly to children using opaque languages.

This study investigated which components of the writing production process are impaired in Spanish children with developmental dyslexia (DD) aged 8 to 12 years. Children with and without dyslexia (n = 60) were assessed in their use of the lexical and the sublexical routes of spelling as well as the orthographic working memory system by manipulating lexical frequency, phonology-to-orthography (P-O) consistency, and word length in a copying task and a spelling-to-dictation task. Results revealed that children with dyslexia produced longer written latencies than chronological age-matched (CA) controls, more errors than CA and reading age-matched (RA) controls, and writing durations similar to CA controls. Latencies were more affected by frequency, consistency, and length in the DD group and the RA group than in CA controls. Children in the DD and RA groups produced longer written latencies in the copying than in the spelling-to-dictation task, while controls in the CA group were not affected by the task. Results indicate that spelling impairments in Spanish children with dyslexia affect the relative involvement of lexical and sublexical information during handwriting. Meanwhile, effects on writing speed seem to be related to deficits in reading ability, and accuracy scores seem to be poorer than expected by children's reading skill.

The methods to measure vocabulary size vary across disciplines. This heterogeneity hinders direct comparisons between studies and slows down the understanding of research findings. A quick, free and efficient test of English language proficiency, LexTALE, was recently developed to remedy this problem. LexTALE has been validated and shown to be an effective tool for distinguishing between different levels of proficiency in English. The test has also been made available in Dutch, German, and French. The present study discusses the development of a Spanish version of the test: Lextale-Esp. The test discriminated well at the high and the low end of Spanish proficiency and returned a big difference between the vocabulary size of Spanish native and non-native speakers.

Abstract Several studies have illuminated how processing manual action verbs (MaVs) affects the programming or execution of concurrent hand movements. Here, to circumvent key confounds in extant designs, we conducted the first assessment of motor-language integration during handwriting--a task in which linguistic and motoric processes are co-substantiated. Participants copied MaVs, non-manual action verbs, and non-action verbs as we collected measures of motor programming and motor execution. Programming latencies were similar across conditions, but execution was faster for MaVs than for the other categories, regardless of whether word meanings were accessed implicitly or explicitly. In line with the Hand-Action-Network Dynamic Language Embodiment (HANDLE) model, such findings suggest that effector-congruent verbs can prime manual movements even during highly automatized tasks in which motoric and verbal processes are naturally intertwined. Our paradigm opens new avenues for fine-grained explorations of embodied language processes.

Orthographic learning is one of the steps needed to achieve reading fluency. There are different variables that could influence the formation of orthographic representations. The aim of this study was to investigate the role of the previous semantic and phonological knowledge on the formation of orthographic representations. We used a decrease of the length effect as the measure of orthographic learning. We made a reading aloud task that utilised new words with Spanish children from third grade under three different conditions: with prior semantic and phonological training, with prior phonological training and without training. Results showed that knowing the meaning and the phonological form of the words facilitated the formation of orthographic representations, as the length effect was significantly lower than in the other conditions, and it also improved the children's reading performance.

The present study addresses the scope of the writing difficulties observed in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Patients with AD, patients with MCI and healthy controls performed a written picture-naming task and a direct copy transcoding task in which phonology-to-orthography (P-O) consistency was manipulated. Written latencies, inter-letter durations, mean word pen pressure and number of errors were measured. Results revealed that there was a significant difference between the control group and both groups of patients in written latencies and number of errors. However, in inter-letter interval or mean pen pressure there were significant differences only between the group with AD and the other groups. P-O consistency and the type of task produced similar effects in the three groups of participants, suggesting a general deficit affecting the ability to access/generate orthographic representations. The relevance of these results for understanding the spelling impairment in AD and MCI are discussed.

Age of acquisition is possibly the single most potent variable affecting lexical access. It is also a variable that determines the retention or loss of words in patients who have suffered brain injury, and in patients with Alzheimer's disease. But the norms of age of acquisition currently available have largely been obtained from university students whereas the ages of acquisition for some words are very different for young people compared with the elderly. The aim of this study was to develop age of acquisition norms for a sample of 500 words with people over 60 years. When these norms were compared with others from young people in predicting the results of a group of Alzheimer patients in a lexical selection task we found that the elderly ratings made a better prediction of the data. We recommend that for studies using older participants appropriate norms should be used in place of those obtained from young adults. (Contains 4 tables.)

Recent studies have shown that word frequency estimates obtained from films and television subtitles are better to predict performance in word recognition experiments than the traditional word frequency estimates based on books and newspapers. In this study, we present a subtitle-based word frequency list for Spanish, one of the most widely spoken languages. The subtitle frequencies are based on a corpus of 41M words taken from contemporary movies and TV series (screened between 1990 and 2009). In addition, the frequencies have been validated by correlating them with the RTs from two megastudies involving 2,764 words each (lexical decision and word naming tasks). The subtitle frequencies explained 6% more of the variance than the existing written frequencies in lexical decision, and 2% extra in word naming. (Contains 2 figures and 2 tables.)

Several studies have found that, after repeated exposure to new words, children form orthographic representations that allow them to read those words faster and more fluently. However, these studies did not take into account variables related to the words. The aim of this study was to investigate the influence of sublexical variables on the formation of orthographic representations of words by Spanish children. The first experiment used pseudo-words of varying syllabic structure and syllabic frequency. The stimuli for the second experiment were formed with or without context-dependent graphemes. We found that formation of orthographic representations was influenced by syllabic structure (easier for words with simple syllabic structure) and the context-dependency of graphemes (easier in the absence of context-dependent graphemes), but not syllabic frequency. These results indicate that the easier it is to read a word, the easier it is to form an orthographic representation of it.

The aim of this study was to investigate the prosody abilities on top of phonological and visual abilities in children with dyslexia in Spanish that can be considered a syllable-timed language. The performances on prosodic tasks (prosodic perception, rise-time perception), phonological tasks (phonological awareness, rapid naming, verbal working memory), visual tasks (visual search) of 32 eleven-year-old children with dyslexia were compared with those of 32 typical readers with the same chronological age and 32 reading-matched younger children. It was found that children with dyslexia scored lower than typical readers on phonological and prosodic perception tasks but not on rise perception tasks. It can thus be concluded that children with dyslexia in Spanish show a prosodic impairment that may originate from subtle auditory-processing deficits.

Reading prosody is considered one of the essential markers of reading fluency, alongside accuracy and speed. The aim of our study was to investigate how development of reading prosody in Spanish children varies with sentence type and length. We compared primary school children from the third and fifth grades with an adult sample. Participants were recorded reading aloud a narrative text including short and long declarative, exclamatory and interrogative sentences. Recordings were analysed using Praat software to measure several prosodic features (i.e., pauses, duration, pitch and intensity). We found that third-grade children had not yet developed an adult-like prosody: they made more pauses, had a flatter melodic contour and had difficulty anticipating sentence structure. Fifth-graders displayed some features of adult prosody. Both length and type of sentence influenced the expressiveness of reading in the three groups. We conclude that reading expressiveness is closely related to reading experience and develops in a similar way to decoding and reading speed.

The present study examined the process of L2 orthographic learning in bilinguals with distant L1–L2 orthographies. Chinese–English bilinguals with various English proficiency levels were trained with novel L2 words during a reading task. In contrast to higher proficient learners, those with lower L2 proficiency exhibited increased effects of length, frequency, and lexicality across exposures and at-chance recognition of trained words. Importantly, an additional post-training task assessing the lexical integration of trained words evidenced the engagement in different L1–L2 reading strategies across different levels of L2 proficiency, hence suggesting the L1 holistic processing at the base of the effortful establishment of L2 orthographic representations shown by lower-proficient learners. Overall, these findings indicate the role of L2 proficiency in the influence that cross-linguistic variation exerts on L2 orthographic learning and highlight the need for English education programmes to tackle specific grapheme-to-phoneme skills in non-alphabetic target communities.

In order to read fluently, children have to form orthographic representations. Despite numerous investigations, there is no clear answer to the question of the number of times they need to read a word to form an orthographic representation. We used length effect on reading times as a measure, because there are large differences between long and short words for unknown words, differences that disappear when reading frequent words. Two lists of new words (half short and half long) were presented to 102 second-grade to sixth-grade Spanish children, to be read aloud six times. One of the lists was presented as part of a story and the other in isolation. Comparison of the length effect at the first and sixth exposure showed large differences between short and long words in the first presentation and small differences at the sixth presentation, indicating that Spanish children develop representations of words after just a few repetitions.

Recent studies show that dyslexia persists into adulthood, even in highly educated and well-read people. The main characteristic that adults with dyslexia present is a low speed when reading. In Spanish, a shallow orthographic system, no studies about adults with dyslexia are available; and it is possible that the consistency of the orthographic system favours the reading fluency. The aim of this study was to get an insight of the reading characteristics of Spanish adults with dyslexia and also to infer the reading strategies that they are using. For that purpose, a group of 30 dyslexics (M age?=?32 years old) and an age-matched group of 30 adults without reading disabilities completed several phonological and reading tasks: phonological awareness tasks, rapid automatic naming, lexical decision, word and pseudoword reading, letter detection and text reading. The results showed that highly educated Spanish dyslexics performed significantly worse than the control group in the majority of the tasks. Specifically, they showed difficulties reading long pseudowords, indicating problems in automating the grapheme-phoneme rules, but they also seem to present difficulties reading words, which indicate problems with the lexical route. It seems that the Spanish dyslexic adults, as in deep orthographies, continue having difficulties in phonological awareness tasks, rapid naming and reading.

Recent research has stated that early oral language acquisition difficulties are related to reading and writing difficulties. Children with developmental language disorder (DLD) experience difficulties with several dimensions of language. In this study we focus on the specific difficulties of children with DLD in spelling. We examine the impact of lexicality and length in written production of Spanish‐speaking children with DLD. A total of 18 children with language difficulties (Mage = 8;4) were compared with age‐matched children (Mage = 8;2). Participants completed a spelling‐to‐dictation task of words and pseudo‐words, where length was manipulated. A digital tablet was used to collect data and obtain measures of accuracy, latencies and total writing durations. Results showed that children with DLD produced more errors, longer latencies and longer writing durations than age‐matched children. Regarding accuracy, analysis of the errors shows that children in the control group produce few errors, most being substitutions, while children with DLD made more errors and of more varied categories. Moreover, they were more affected by length on writing accuracy than the control group. WHAT THIS PAPER ADDS: What is already known on this subject: Children with language difficulties are more likely to present reading difficulties. There are fewer studies analysing the impact of oral language difficulties in writing skills. What this paper adds to existing knowledge: The study suggests that children with oral language difficulties also have impairments in spelling, impacting on accuracy, duration and reaction time, possibly related to poor phonological working memory. What are the potential or actual clinical implications of this work?: This study highlights the need to emphasize early oral intervention and language‐related processing skills to help prevent written language difficulties.

Reading fluency is one of the basic processes of learning to read. Children begin to develop fluency when they are able to form orthographic representations of words, which provide direct, smooth, and fast reading. Dyslexic children of transparent orthographic systems are mainly characterized by poor reading fluency (Cuetos & Suárez-Coalla 2009; Spinelli, De Luca, Di Filippo, Mancini, Martelli, & Zoccolotti, 2005; Wimmer, 1993). Therefore, the main problem for these children could be the difficulty in developing orthographic representations of the words they read. The aim of this study was to test the ability of dyslexic Spanish-speaking children (whose native language is Spanish) to develop orthographic representations and determine if the context helps them. For this, two experiments were conducted with a group of 100 children, 7-12 years of age. The groups were comprised of 20 dyslexics, 40 chronological age-matched controls and 40 reading level-matched controls. In the first experiment, eight unfamiliar words (four short and four long) were presented six times within the context of a story. In the second experiment, eight pseudowords were presented on a computer and the children had to read them aloud. In both experiments, the reading and articulation times of experimental and control stimuli were compared, before and after the training. Children without dyslexia showed a decrease of the influence of length of word on reading speed, indicating a lexical reading, while for dyslexic children, the influence of length remained unchanged. These results appeared when the stimuli were presented in the context of a story as well as when presented in isolation. In short, our results describe that dyslexic children of transparent orthographic systems have problems in developing orthographic representations of words.

Word age-of-acquisition (AoA) affects reading. The mapping hypothesis predicts AoA effects when input--output mappings are arbitrary. In Spanish, the orthography-to-phonology mappings required for word naming are consistent; therefore, no AoA effects are expected. Nevertheless, AoA effects have been found, motivating the present investigation of how AoA can affect reading in Spanish. Four experiments were run to examine reading with a factorial design manipulating AoA and frequency. In Experiments 1 and 2 (immediate and speeded naming), only word frequency affected word naming. In Experiment 3 (lexical decision), both AoA and frequency affected word recognition. In Experiment 4 (immediate naming with highly imageable items), both frequency and AoA affected naming. The results suggest that highly imageable items induce a larger reliance on semantics in reading aloud. Such reliance causes faster naming of earlier acquired words because the corresponding concepts have richer visual and sensory features acquired mainly through direct sensory experience.

In an opaque orthography like English, phonological coding errors are a prominent feature of dyslexia. In a transparent orthography like Spanish, reading difficulties are characterized by slower reading speed rather than reduced accuracy. In previous research, the reading speed deficit was revealed by asking children to read lists of words. However, speed in list reading sums the time required to prepare an utterance, reaction time (RT), with the time required to say it, response duration (RD). Thus, the dyslexic speed deficit in transparent orthographies could be driven by slow RTs, by slow RDs, or both. The distinction is especially important if developmental readers rely on phonological coding to achieve lexical access because the whole word would have to be encoded before it could be identified. However, while the factors that affect reading RT have been extensively investigated, no attention has been paid to RD. We studied the performance of typically developing and dyslexic Spanish children in an oral reading task. We analysed the impact of word frequency and length on reading accuracy, RT, and RD. We found that accuracy, RT, and RD were affected by word frequency and length for both control and dyslexic readers. We also observed interactions between effects of reader group--dyslexic, typically developing (TD) younger or TD older readers--and effects of lexicality, frequency, and word length. Our results show that children are capable of reading aloud using lexical and sub-lexical coding processes in a transparent orthography.

Albanian is an Indo-European language with a shallow orthography, in which there is an absolute correspondence between graphemes and phonemes. We aimed to know reading strategies used by Albanian disabled children during word and pseudoword reading. A pool of 114 Kosovar reading disabled children matched with 150 normal readers aged 6 to 11 years old were tested. They had to read 120 stimuli varied in lexicality, frequency, and length. The results in terms of reading accuracy as well as in reading times show that both groups were affected by lexicality and length effects. In both groups, length and lexicality effects were significantly modulated by school year being greater in early grades and later diminish in length and just the opposite in lexicality. However, the reading difficulties group was less accurate and slower than the control group across all school grades. Analyses of the error patterns showed that phonological errors, when the letter replacement leading to new nonwords, are the most common error type in both groups, although as grade rises, visual errors and lexicalizations increased more in the control group than the reading difficulties group. These findings suggest that Albanian normal children use both routes (lexical and sublexical) from the beginning of reading despite of the complete regularity of Albanian, while children with reading difficulties start using sublexical reading and the lexical reading takes more time to acquire, but finally both routes are functional.

Background: The expressiveness during reading is essential for a fluent reading. Reading prosody has been scarcely studied in an experimental manner, owing to the difficulties in taking objective and direct measures of this reading skill. However, new technologies development has made it possible to analyse reading prosody in an experimental way. Prosodic patterns may vary, not being the same at the beginning of the reading learning process as in adulthood. They may also be altered in disorders such as dyslexia, but little is known about the prosodic characteristics and reading fluency of people with neurodegenerative diseases that cause language impairment, such as Parkinson's disease (PD). Aims: The aim of this work was to study reading fluency in PD considering the prosodic characteristics of its reading. Methods & Procedures: The participants were 31 Spanish adults with PD and 31 healthy controls, aged 59–88 years. Two experimental texts were designed that included declarative, interrogative, and exclamatory sentences and experimental verbs and nouns. The manipulability level of the nouns and the motor content of the verbs were considered. The reading of the participants was recorded and analysed with Praat software. Outcomes & Results: A longer reading duration and a greater number of pauses, especially in verbs, were found in the PD group, which also showed less pitch variation than the control group in the experimental sentences. The control group showed a big initial rise in declarative and interrogative sentences, as well as a stronger final declination in declarative and exclamatory ones, when compared to the PD group. Conclusions & Implications: The use of experimental methodologies for the analysis of reading fluency allows learning more about the prosodic characteristics of people with different pathologies, such as PD. Scarce pitch variability found in the analysis, together with the great number of pauses and the longer reading duration, leads to poorly expressive reading, which compromises fluency in PD. The exhaustive evaluation of the reading fluency of PD patients will make it possible to design more complete assessment methods that will favour the diagnosis and early detection of this pathology. What this study adds: What is already known on this subject: • The speech of people with Parkinson's disease (PD) is often impaired by the appearance of hypokinetic dysarthria. The language of people with PD is usually affected with the progression of the disease, with lexico‐semantic impairment which mainly affects verbs. Previous literature on reading fluency in PD usually considers reading speed and accuracy, neglecting prosody. Other neurodegenerative diseases with language impairment, such as Alzheimer's disease, commonly cause reading fluency problems. What this paper adds to existing knowledge: • This study provides direct and objective measures of the reading fluency (speed, accuracy and prosody) in patients with PD, by the design of experimental texts. Reading fluency characteristics were found to be altered in these patients, especially in pitch variations and reading duration. The reading of Parkinson's patients showed a more flattened pitch. In addition, a greater number of pauses and longer reading durations were also found in the reading of verbs compared to the control group. What are the potential or actual clinical implications of this work?: • The use of experimentally created texts makes it possible to analyse the influence of different psycholinguistic variables (frequency, length, motor content, manipulability) on reading fluency, and how the processing of these stimuli could be affected in PD. The objective analysis of the reading fluency characteristics in PD allows the design of more specific evaluation and diagnostic tasks. More complete assessment methods may allow the early detection of the disease. In the same way, it may favour a differential diagnosis with other neurodegenerative diseases. [ABSTRACT FROM AUTHOR]

Cross-linguistic studies suggest that the orthographic system determines the reading performance of dyslexic children. In opaque orthographies, the fundamental feature of developmental dyslexia is difficulty in reading accuracy, whereas slower reading speed is more common in transparent orthographies. The aim of the current study was to examine the extent to which different variables of words affect reaction times and articulation times in developmental dyslexics. A group of 19 developmental dyslexics of different ages and an age-matched group of 19 children without reading disabilities completed a word naming task. The children were asked to read 100 nouns that differed in length, frequency, age of acquisition, imageability, and orthographic neighborhood. The stimuli were presented on a laptop computer, and the responses were recorded using DMDX software. We conducted analyses of mixed-effects models to determine which variables influenced reading times in dyslexic children. We found that word naming skills in dyslexic children are affected predominantly by length, while in non-dyslexics children the principal variable is the age of acquisition, a lexical variable. These findings suggest that Spanish-speaking developmental dyslexics use a sublexical procedure for reading words, which is reflected in slower speed when reading long words. In contrast, normal children use a lexical strategy, which is frequently observed in readers of opaque languages.
