Children with developmental dyslexia (DD) display partially preserved morphology skills which they rely upon for reading and spelling. Therefore, we conducted explicit and intensive training of derivational morphology in French and Swiss individuals with DD, ages 9 to 14 years, in order to assess its effect on: morphological awareness, reading…

Visual-verbal paired-associate learning (PAL) is thought to be related to reading acquisition and, more specifically, to word reading skills. To date, the uniqueness and strength of this relationship has remained unclear because most studies have been conducted in opaque orthographies such as English, and few studies have controlled for all of the…

A central objective of schooling processes at the international level is reading skills development. Unfortunately, many students in the European Union underperform at this, and these low performances can be more pronounced in countries with lower Human Development Index (HDI) values. This study analysed the contextual effect of school…

The French National Cohort of Children Study ("Etude Longitudinale Française depuis l'Enfance"--ELFE) tested the literacy and numeracy skills of 4- to 5-year-old typically developing children in the second year of "école maternelle." Tasks were administered by more than 4,000 teachers at schools across France. One of the…

Previous studies indicate that children are exposed to different literacy experiences at home. Although these disparities have been shown to affect children's literacy skills, it remains unclear whether and how home literacy practices influence brain activity underlying word-level reading. In the present study, we asked parents of French children…

This study aims to identify the literacy skills of individuals whose highest level of education was in the field 'teacher training and educational sciences'. The study sample comprised 10,618 individuals in the field of teacher training and educational sciences, selected from 31 countries (participating in the International Adult Skills Assessment…

Handwriting deficits, or dysgraphia, are present in several neurodevelopmental disorders. To investigate whether dysgraphia differs according to the associated disorder, we performed a detailed analysis of handwriting in a group of French children with developmental coordination disorders (DCD), reading disorder (RD), or comorbid RD and DCD.…

A wide share of secondary school children does not reach the expected competence level in reading. These children could benefit from more efficient intervention responses, providing a better understanding of their cognitive weaknesses/deficits. Our aim was to explore the cognitive heterogeneity of a population of poor readers identified from a…

Purpose: Multiple factors impact reading acquisition in individuals with reading disability, including genetic disorders such as Williams syndrome (WS). Despite a relative strength in oral language, individuals with WS usually have an intellectual disability and tend to display deficits in areas associated with reading. There is substantial…

In the present study, the frequency effect was examined specifically in text reading in developing and expert readers. Third graders, fifth graders, and expert readers read the same short text containing high- and low-frequency words while their eye movements were recorded. The frequency effect was observed in temporal and spatial measures of eye…

Background: Educational qualifications and literacy skills are highly related. This is not surprising as it is one aim of educational systems to equip individuals with competencies necessary to take part in society. Because of this relationship educational qualifications are often used as a proxy for "human capital". However, from a…

There is a strong international demand for official certification of French competence. A range of tests are available to meet this goal. Among the recognized tests available for this purpose is the "DELF" ("Diplôme d'études en langue française"). The "DELF" has been awarded the Association of Language Testers in…

A letter-search task was used to test the hypothesis that affixes are chunked during morphological processing and that such chunking might operate differently for prefixes and suffixes. Participants had to detect a letter target that was embedded either in a prefix or suffix (e.g., "R" in "propoint" or "filmure") or…

Executive functions (EFs; working memory [WM], inhibition, and shifting) are widely known to play a critical role in school achievement. Among these EFs, WM appears to be implicated in numeracy and literacy. The contribution of inhibition and shifting to school achievement is less clear. Given the existing divergences in the literature and the…

Most earlier studies investigating the evolution of the Stroop effect with the amount of reading practice have reported data consistent with an inverted U-shaped curve, whereby the Stroop effect appears early during reading acquisition, reaches a peak after 2 or 3 years of practice, and then continuously decreases until adulthood. The downward…
