About
The present project will therefore focus upon those processes related to visual attention and perceptual abilities and on their potential to explain reading behavior and reading problems in NF1. The main objective of this study is to clarify the specificity and heterogeneity of reading profiles and the causes of its disturbance in NF1. In particular, this project allow the investigators to study more precisely the relations between perceptual, oculomotor and visuo-attentional skills in NF1 children and reading abilities. In addition, a new oculomotor/perceptual reading aid for NF1 children will be evaluated. The investigators believe that the early intervention for perceptual, visuo-attentional or oculomotor problems may promote academic skill development.
Full description
Although some NF1 children manage in the end to exhibit "expert" reading behavior, a non-negligible number of them have real problems learning this skill. Today's estimates indicate that 30-60% of NF1 children suffer from written-language learning disorder. Studies of the effects of the neurocognitive deficit on academic performance are relatively rare, owing to the small size of the populations concerned. However, research is needed to develop effective rehabilitation programs. At the current time, most tools available to professionals are designed for the evaluation and remediation of child language problems, particularly difficulties related to the acquisition of meta-phonological skills. The findings from dyslexics and typically developing readers however suggest a strong relationship between reading ability and visual processing. The main goal of this study is to investigate the occurrence of perceptual, visuo-attentional and oculomotor deficits in NF1 children and their potential to explain reading behavior and reading problems in this population. The investigators hope to contribute to the process of clarifying the specificity and heterogeneity of reading profiles and the causes of its disturbance in NF1. The second objective of the study is to evaluate an oculomotor/perceptual reading aid for NF1 children; in particular, the idea of the training is to help the readers to land their saccades at the optimal viewing position1 (OVP) of each word (highlighting the letter at the OVP or putting it in color, so that the saccades they make would land near the centre of the word, at the OVP). Eye movement control during reading is a highly automated process; people are not aware of most of the saccades and fixations they make. This tool is a way to train children to control these subconscious saccades and fixations. Note that, our team has already demonstrated the usefulness of this reading aid for beginning readers. This project have important implications from a clinical perspective, by providing the opportunity to gain insight into the reading difficulties of NF1 children, in view of establishing thorough and accurate assessment procedures and proposing child-specific guidelines and remediation methods that take into account the particular processes affected. Providing a clearer picture of visuo-attentional and perceptual skills in children with NF1 would be of considerable clinical benefit, not least for supporting targeted clinical practices. Moreover, NF1 children could benefit from a new remediation tool that allow them to have feedback on their reading ability, and to read more easily, more rapidly, and with better comprehension. If appropriate interventions are implemented at an early age, academic skill development could be altered, preventing subtle learning difficulties from becoming more pronounced over time.
