Figure 4

Mean results for unprocessed tones with both references D (a) and G# (b) in octaves 3, 4, and 5 with 1, 3, and 6 semitone intervals between the probe and reference tones. Pitch reversals, which would be indicated by negative scores, were not observed at all. Columns marked with an asterisk are significantly above chance according to the cumulative binomial distribution of mutually exclusive events; at least 7/8 correct answers are considered significant. Chance level is indicated by the dashed line.
