Can intervention programs influence how the dyslexic brain processes low-level visual stimuli?

This preliminary study employed event-related potentials (ERPs) to determine the effect of different intervention programs for dyslexia. Two intervention programs were used; the CogniFit Personal Coach (CPC) and the Reading Acceleration Program (RAP). Differences between a small group of dyslexic readers and a control group of regular readers were examined on two visual oddball tasks. The two oddball tasks included a non-alphabetic task and a non-contextual alphabetic one. The amplitude and latency of ERP component P1 is reported here, showing a decrease in amplitude and an increase in latency after training, suggesting an amplitude-latency tradeoff after visual training.
