Primary Outcome Measures

Name	Time	Method
<p>The current study consists of two ERP experiments. In the first experiment, we<br /><br>investigate the automatization deficit of dyslexia by looking at two neuronal<br /><br>activities that are closed related with automaticity acquisition, i.e.,<br /><br>orienting response and its habituation. The main study parameters are the<br /><br>amplitude and latency of two ERP components i.e., N1 and P3, both of which are<br /><br>the neurophysiological correlates of orienting response and its habituation. In<br /><br>the second experiment, we investigate neurophysiological markers of dyslexia in<br /><br>the domain of auditory perception. The main study parameter is the mismatch<br /><br>negativity, an ERP component which is an objective measure of the accuracy of<br /><br>auditory perception. </p><br>
