Intervention study, Quasi-experimental |
52 individuals (22 controls e 30 with APD) |
8 to 14 years (11) |
APD group presented longer latencies and shorter amplitudes compared to control group; it showed reduced latency of Na and Pa and increased Na-Pa amplitude after auditory training. |

Cross-sectional |
155 individuals with typical development |

There was no difference to ear or electrode effects depending on age; the variation of electrode effect was smaller than ear effect; the average electrode effect was significantly higher than average ear effect. |
