Figure 4.

Separability of sound categories in music-selective components of nonmusicians and musicians. Distributions of 1) instrumental music stimuli, 2) vocal music stimuli, 3) speech stimuli, and 4) other stimuli within the music component response profiles from our previous study (n = 10; left, gray shading), as well as those inferred from nonmusicians (n = 10; center, green shading) and musicians (n = 10; right, blue shading). The mean for each stimulus category is indicated by the horizontal black line. The separability between pairs of stimulus categories (as measured using Cohen’s d) is shown above each plot. The 165 individual sounds are colored according to their semantic category. Stimuli consisted of instrumental music (n = 22), vocal music (n = 11), speech (n = 17), and other (n = 115). See Table 2 for results of pairwise comparisons indicated by brackets; ****Significant at P < 0.0001, two-tailed.
