ERPs from the selective auditory attention paradigm, averaged across all participants in each group, separately at pretest and at posttest. Children were cued to attend selectively to one of two stories presented simultaneously from separate speakers located to the left and right of the child. The electrophysiological response to identical probes embedded in attended and unattended stories was compared. Significantly greater increases in the ERP early attentional modulation (100–200 ms) in children in the PCMC-A group compared with the HS-alone and ABC groups in representative waveforms from centro-parietal electrode P4. Complete waveforms for each analysis are provided in SI Appendix.
