Figure 1. The Probability of Vocal Responses by Marmoset Monkeys Is Related to the Size of Their White Facial Patch.

Figure 1.

(A) Adult common marmosets all exhibit a prominent white facial patch on their foreheads. We measured their area using image analysis software.

(B) Example of a vocal exchange between two adult marmosets. Top panel shows the time-amplitude waveforms, and the bottom panel shows the spectrogram.

(C) Correlation between white patch size and probability to respond to a conspecific call. Red solid line is the regression line, the blue circles are the data points, and the dotted red lines show the 95% confidence interval.

See Figure S1.
