FIG. 1.

Schematic diagram of the rhythmic stimulus patterns that featured anisochronous timing or an elevated frequency component. The label for each pattern indicates the order of the sequence tonal inter-onset intervals (IOI), either S (short) or L (long); the underlined interval indicates sequence position of the target IOI, which is also marked with an arrow on the schematic of the sequence. The two patterns on the right also show a single tonal component that is shifted vertically to indicate a half-octave frequency increment.
