Overview
Brief Summary
This study will help to better characterize oral and written language disorders and determine if these disorders are continuous or not. The participants ( dyslexic and dysphasic patients and control adults) will carry out an auditory lexical decision task during which an electroencephalogram (EEG) will be recorded.

Outcomes
Primary Outcomes
Score Alouette reading test
Time Frame: at inclusion
In this test, the participant has to read in a loud voice a text, during three minutes. The final score takes into account the speed and the number of errors. For test performance, clinical groups will be compared with its controls.
Score EVALEC reading test
Time Frame: at inclusion
For test performance, clinical groups will be compared with its controls.
Score silence reading test
Time Frame: at inclusion
A group of letters will be presented and the participant has to say if this letters compose a known word. For test performance, clinical groups will be compared with its controls.
Score of reading comprehension test
Time Frame: at inclusion
For test performance, clinical groups will be compared with its controls.
Score of Khomsi
Time Frame: at inclusion
The objective of this group of different tests is to evaluate comprehension and production of oral language. For test performance, clinical groups will be compared with its controls.
Secondary Outcomes
- Measure of the electroencephalography power spectra(at inclusion)
- Correlation between electroencephalography power spectra and clinical outcome(at inclusion)
