FIGURE 7

The entrainment process. (A) Tap-dependent changes in RT for rhythmic tapping (dark green) and “joining the rhythm” tapping (light green). Negative synchronization was obtained much faster when subjects “joined the rhythm” compared to unprimed tapping. (B) Tap-dependent changes in mean CV of acceleration profile computed in a test window spanning -150 to -50 ms before the tap. The CV values decreased gradually and not in an episodic manner. (C) CVt of acceleration profile of the first three taps and the last five taps computed for rhythmic tapping (light and dark brown) and random tapping (light and dark cyan). (D) Mean CV of acceleration computed for the first three taps (light colors) and the last five taps (dark colors) in rhythmic (brown) and random (blue) conditions. Significant differences were found for rhythmic (paired t-test, p < 0.01) but not for random tapping. Data for panel (A) were taken from experimental set B and C separately. Data for panels (C,D) were taken from experimental set A and B.
