Figure 1.

Schematic illustration of experimental tasks, with one reference and one target example depicted per task. (A) Pitch: basic change detection (p1); change-direction discrimination (p2); detection of a local change in pitch sequence (p3); detection of a global change in pitch sequence (p4). (B) Rhythm and timing: single time-interval discrimination (r1); isochrony deviation detection (r2); metrical pattern discrimination for a strongly (r3) and a weakly metrical sequence (r4). (C) Modulation (timbre): 2 Hz frequency modulation (FM) detection (m1); 40 Hz FM detection (m2); dynamic modulation (DM) detection (m3); dynamic modulation discrimination (m4). Note: x- and y-axes correspond to time and frequency throughout, but scales vary and are in part arbitrary.
