Four vocal stimuli of Macaca fuscata and a 1000Hz tone, as a control, were presented to 11 Macaca fuscata by a modified method of overlapped Latin square, and their skin potential reflexes (SPRs) were measured. The SPR showed smaller amplitude and faster habituation to the pure tone than to the four vocal stimuli (p<.001). The median of amplitude of SPR to each stimulus was as follows: 1) To sounds generally emitted in peaceful states of emotion: 1.85mV, 2) To defensive sounds: 2.00mV, 3) To agressive sounds: 2.70mV, 4) To warning sounds: 2.50mV, and 5) To tone: 0.93mV. The SPR to the agressive sounds were greater than to the other vocal signs excepting the warning sounds (p<.05).
