Figure 1. Schematic of the auditory stimulus to test auditory streaming.
The auditory stimulus was an asynchronous sequence of two types of tone bursts: tone A and tone B. Typically, tones A and B were presented asynchronously but were at times presented simultaneously (see inset at upper left). The frequency of tone A, the frequency difference between the tones A and B (ΔF), and the listening duration (i.e., the duration of the auditory sequence) varied on a trial-by-trial basis. The units on the x- and y-axes are arbitrary.
