No dependence of AEF reduction with tone repetition on the number of repeated tones. The magnitudes of the AEF at cM20 (diamond), cM50 (star), and cM140 (circle) for the last tones in all tone series (y-axis) are plotted against the AEF magnitudes for second tones in all tone series (x-axis) for each subject; dashed line indicates equal magnitude (slope=1). The last tone was the eighth tone for 200 ms IOI (A) and 400 ms IOI (B) series, and the fourth tone for 800 ms IOI series (C). There was no significant difference between the AEF extrema magnitudes for the second versus last tones in any of the stimulus conditions, for any of the subjects (t-test with Holm-Bonferroni correction, p > 0.05.)
