Fig. 2: Responses to coronal tap, plural, and past tense comparisons exhibit both surface similarity and underlying similarity patterns.

Subplot titles indicate the subject identity, channel name, and response band being plotted, and each shows the time course of band power z-scored relative to baseline (-100 to 0 ms). (a) and (b) show sites identified by the coronal stop-tap alternation. The evoked response to tokens of [t] are shown in dark gray (n=796); the evoked response to taps derived from /t/ (tap /t/) is shown in teal (n=183); and the evoked response to taps derived from /d/ (tap /d/) is shown in gold (n=79). (c) and (d) show sites identified by the past tense alternation. The evoked response to /t/ allomorphs of the past tense are shown in dark gray (SD021: n=15, SD011: n=20); the evoked response to /d/ allomorphs of the past tense is shown in teal (SD021: n=52, SD011: n=53); and the evoked response to word-final non-past tokens of /d/ is shown in gold (SD021: n=141, SD011: n=138). (e) and (f) show sites identified by the plural alternation. The evoked response to /s/ allomorphs of the plural is shown in dark gray (n=51); the evoked response to /z/ allomorphs of the plural is shown in teal (n=105); and the evoked response to word-final non-plural tokens of /z/ is shown in gold (n=194). For all subplots, shading indicates ±SEM. The distribution of sites across bands for each comparison is shown in Supplementary Fig. 3.
