Brice is a post-doctoral fellow at the LPL within the framework of the AMPIRIC-funded DREAM project, which aims to gain a better understanding of the factors involved in children's exposure to the written word in the first year of primary school, in order to develop a programme of personalised recommendations for learning to read. He coordinates this project together with Stéphanie Ducrot (LPL/CNRS).

What role does neurofibromatosis type 1 play in learning to read?

We are pleased to announce the recent publication of the latest article produced by Marie Vernet (neuropsychologist and former doctoral student at LPL), Stéphanie Ducrot (CNRS researcher at LPL) and Yves Chaix (Tonic, CHU Toulouse) which includes a systematic review on visual processing deficits in neurofibromatosis type 1 and the impact on learning to read.

It follows the study “The determinants of saccade targeting strategy in neurodevelopmental disorders: The influence of suboptimal reading experience” published in 2023 in the journal Vision Research.

Learning to read with Neurofibromatosis Type 1

We are pleased to share with you the latest article published in the journal Vision Research by Marie Vernet (ToNIC / LPL / CLLE) and Stéphanie Ducrot (LPL) in collaboration with colleagues from Aix, Montpellier and Toulouse:

Reference: Vernet, M., Bellocchi, S., Danna, J., Massendari, D., Jover, M., Chaix, Y., Ducrot, S. (2023). The determinants of saccade targeting strategy in neurodevelopmental disorders: The influence of suboptimal reading experience. Vision Research, 204, 108162

 Abstract: Whether eye-movements deficits are causal in reading disorders (RD) or rather a consequence of linguistic processing difficulty experienced by disabled readers has been extensively debated.Since RD are frequently comorbid with the Neurofibromatosis type1 (NF1), children with NF1 were used as a comparison group for children with dyslexia in this study.Eye movements were recorded while 21 dyslexic, 20 NF1, and 20 typically developing children performed an oculomotor lateralized bisection task. In this experiment, we manipulated the type of stimulus - discrete (words and strings of hashes) versus continuous (solid lines) - and the visual field where the stimulus was displayed (left vs right). The results showed that (1) only proficient readers (TD and NF1 without RD) showed fully developed oculomotor mechanisms for efficient reading, with a clear preferred viewing location located to the left of the word's centre in both visual fields, and fine-tuned saccade targeting guided by the between-character space information and (2) NF1 poor readers mirrored the dyslexic eye movement behaviour, with less accuracy and more variability in saccadic programming, no sensitivity to the discreteness of the stimuli, particularly in the left visual field. We concluded that disruption to oculomotor behaviour reflectsthe fact that many of the processes involved in reading are not yet automatized for children with RD, independently of NF1. This suggests that the differences in saccade targeting strategy between children with and without RD would be secondary consequences of their reduced reading experience.

Can text simplification improve reading fluency and comprehension?

We are pleased to announce the publication of the article "Simplification of literary and scientific texts to improve reading fluency and comprehension in beginning readers of French" co-written by Núria Gala (LPL-AMU) and colleagues from the research structures LPC, ADEF, SCALab and IL&C.

Visuo-attentional and reading skills: the look says it all

In its July issue of the AMU Letter, Aix-Marseille University devoted a brief to the last article by Stéphanie Bellocchi (Epsylon Montpellier) and Stéphanie Ducrot (LPL) published in the journal Dyslexia:

Can we predict reading difficulties from the visual skills assessed in kindergarten?

Marie Vernet, doctoral student at the LPL and at the Toulouse NeuroImaging Center (ToNIC), is the first author of an article published in the journal Applied Neuropsychology: Child entitled "Predicting future poor readers from pre-reading visual skills". She carried out the study in collaboration with Stéphanie Ducrot (LPL) and Yves Chaix (ToNIC) as well as Stéphanie Bellocchi (EPSYLON Montpellier) and Laurie Leibnitz (CMPP Fort-de-France), two former members of the LPL.

Dyslexic (or not), how do we activate phonological codes when reading?

Phonological codes play a key role in learning to read. In this article, published in July in the journal Annals of Dyslexia, Ambre Denis-Noël (PhD) and Chotiga Pattamadilok (CNRS researcher) - in collaboration with two colleagues from the LPC Marseille - study the activation of these codes in typical readers and dyslexic readers, by tracing their eye movements when reading.

Reading aid: ALECTOR database available on Huma-Num

The corpus database of the Alector project is now available for consultation on the following website:

It was created as part of the ANR Alector project and offers reading assistance mainly for children who are weak readers and have dyslexia.
