Design outcomes

Primary

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