Article Synopsis
  • The study aims to create tools for screening dyslexia in adults entering university by validating seven different tests, including reading and spelling assessments, and a self-report questionnaire.
  • Researchers used machine learning techniques to determine the best combination and sequence of these tests for accurate dyslexia detection.
  • Results showed that a combination of four specific tests could achieve about 90% accuracy in diagnosing dyslexia, highlighting a more efficient screening method with practical implications for both clinical and theoretical applications.

Intervention in the early years can help to mitigate the risks that early language and communication difficulties pose for later learning and well-being. Critical to this is the capacity of early years educators to evaluate language development accurately in the classroom in order to target individual support effectively. This article reports on the development and testing of the Early Language in Play Settings (eLIPS) tool, an observational measure of child language.

This study aimed to investigate phonological activation during silent word reading in French adolescents learning English as a second language (L2) at secondary school. Grade 6 and Grade 8 adolescents performed lexical decision tasks in English, where we compared processing of nonwords that were homophonic to real L2 words (i.e.

Purpose Of Review: Although spoken language in the form of meta-linguistic awareness is widely regarded as being involved in reading development, the extensive literature based on different experimental tasks, age groups, and languages makes it difficult to establish consensus about the type of awareness that is critical and the mechanisms underlying this relationship. The purpose of this review is to explore the links between reading and two specific aspects of meta-linguistic awareness, namely, phoneme awareness and morpheme awareness.

Recent Findings: Research has uncovered distinct levels of meta-linguistic awareness that stand in different relationships to learning to read.

Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Research on the development of morphological skills in this group is scarce, and no studies exist in French. The present study investigated the involvement of morphological knowledge in the very early stages of reading acquisition (decoding), before reading comprehension can be reliably assessed.

Previous masked priming research has shown automatic phonological activation during visual word recognition in monolingual skilled adult readers. Activation also occurs across languages in bilingual adult readers, suggesting that the activation of phonological representations is not language specific. Less is known about developing readers.

A phonological deficit constitutes a primary cause of developmental dyslexia, which persists into adulthood and can explain some aspects of their reading impairment. Nevertheless, some dyslexic adults successfully manage to study at university level, although very little is currently known about how they achieve this. The present study investigated at both the individual and group levels, whether the development of another oral language skill, namely, morphological knowledge, can be preserved and dissociated from the development of phonological knowledge.

In this article, we introduce HelexKids, an online written-word database for Greek-speaking children in primary education (Grades 1 to 6). The database is organized on a grade-by-grade basis, and on a cumulative basis by combining Grade 1 with Grades 2 to 6. It provides values for Zipf, frequency per million, dispersion, estimated word frequency per million, standard word frequency, contextual diversity, orthographic Levenshtein distance, and lemma frequency.

This study investigates the concurrent predictors of adolescent reading comprehension (literal, inferential) for fiction and non-fiction texts. Predictors were examined from the cognitive (word identification, reading fluency), psychological (gender), and ecological (print exposure) domains. Print exposure to traditional and digital texts was surveyed using a diary method of reading habits.

Developing readers have been shown to rely on morphemes in visual word recognition across several naming, lexical decision and priming experiments. However, the impact of morphology in reading is not consistent across studies with differing results emerging not only between but also within writing systems. Here, we report a cross-language experiment involving the English and French languages, which aims to compare directly the impact of morphology in word recognition in the two languages.

An important aspect of learning to read is efficiency in accessing different kinds of linguistic information (orthographic, phonological, and semantic) about written words. The present study investigates whether, in addition to the integrity of such linguistic skills, early progress in reading may require a degree of cognitive flexibility in order to manage the coordination of this information effectively. Our study will look for evidence of a link between flexibility and both word reading and passage reading comprehension, and examine whether any such link involves domain-general or reading-specific flexibility.

Phonological development was assessed in six alphabetic orthographies (English, French, Greek, Icelandic, Portuguese and Spanish) at the beginning and end of the first year of reading instruction. The aim was to explore contrasting theoretical views regarding: the question of the availability of phonology at the outset of learning to read (Study 1); the influence of orthographic depth on the pace of phonological development during the transition to literacy (Study 2); and the impact of literacy instruction (Study 3). Results from 242 children did not reveal a consistent sequence of development as performance varied according to task demands and language.

The study investigated the extension of rhyme awareness to disyllabic stimuli. Three experiments are reported which examine the disyllabic rhyme production skills of adults and of children in their first, second or third year of schooling. Stress pattern and phonological rime and superrime neighbourhood density were manipulated.

Phonological awareness is thought to become increasingly analytic during early childhood. This study examines whether the proposed developmental sequence (syllable --> onset-rime --> phoneme) varies according to the characteristics of a child's native language. Experiment 1 compares the phonological segmentation skills of English speakers aged 4;11 (N = 10), 5;3 (N = 21), and 6;5 (N = 23) and French speakers aged 5;6 (N = 35), and 6;8 (N = 34).
