Figure 6.

Induction of streaming with alternating two tone sequences. The model’s segregation of alternating two-tone sequences is tested with different stimulus parameters and averaged across 25 repetitions. The frequency separation and tone repetition time values tested are shown with the white diamond-shaped points. The surface shown in the figure is an interpolation of the results from these points using a cubic 2D interpolation. The white contour represents a contour of 25% to indicate a potential coherence boundary. The low tone in the sequence was fixed at 850 Hz, while the high note was placed3, 6, 9, 12 semitones higher. Each tone was 75 ms long.
