A repeated-measures ANOVA was used to evaluate the effects of the between-group variable (synchronization ability group) with the within-group variables considered. Significant interaction effects are represented. (a) As for envelope-encoding precision, a significant interaction was found between all three factors-presentation mode (Quiet: solid line; Noise: dotted line) x time region x synchronization group (F = 4.314, p = 0.012, ηp2 = 0.071). As for response consistency, the following significant interactions are represented: (b) polarity (Added: solid line; Subtracted: dotted line), time region, and synchronization group (p < 0.01). (c) Presentation mode, polarity (Added: solid line; Subtracted: dotted line), and synchronization group (p < 0.01). As for phase-locking consistency, the following significant interactions are represented: (d) time region of the FFR, presentation mode (Quiet: solid line; Noise: dotted line), and synchronization group (p < 0.05), and (e) an interaction between time region of the FFR, frequency (Low: solid line; High: dotted line), and synchronization group (p < 0.05). For all graphs, Non-synchronizer means are shown by the black lines and Synchronizer means are the red lines. Means for the FFR measure considered are displayed on the y-axis. Error bars represent ± 1 standard error.
