Figure 5

The proportion of trials perceived as streaming in the Behavioral experiment, illustrating the effect of the initial Adaptation on the streaming perception of the subsequent Test. The Upper section plots the averaged proportion of trials in the 4 and 10 semitones condition which were perceived as two streams when presented in the Test position (proceeded by the 2 semitone stimuli), allowing comparison with the perception of the same stimuli presented in the Adaptation position. The Lower section plots the proportion of trials heard as two streams in the 2 semitones scenario when presented as both Test (preceded by 4 and 10 semitones) and as Adaptation sequences. Error bars represent the standard error of the mean.
