Figure 3.

Electrophysiological responses of dyslexic children in the training and control groups (11 children in each group) at the frontal scalp to tone-order reversals (the response elicited by the standard pair subtracted from that elicited by the deviant pair). The responses of the training group are presented with the thick line and those of the control group (with no audiovisual training) with the thin line. Responses before (Upper) and after (Lower) the audiovisual training are shown. No significant group differences were obtained for the responses measured before the training. In contrast, after the training, the earlier parts of the MMN response were enhanced in the training group as compared with those of the control group.
