Expression of Emotional Arousal in Two Different Piglet Call Types

Popis výsledku v původním jazyce

Humans as well as many animal species reveal their emotional state in their voice. Vocal features show strikingly similar correlation patterns with emotional states across mammalian species, suggesting that the vocal expression of emotion follows highlyconserved signalling rules. To fully understand the principles of emotional signalling in mammals it is, however, necessary to also account for any inconsistencies in the way that they are acoustically encoded. Here we investigate whether the expressionof emotions differs between call types produced by the same species. We compare the acoustic structure of two common piglet calls-the scream (a distress call) and the grunt (a contact call)-across three levels of arousal in a negative situation. We findthat while the central frequency of calls increases with arousal in both call types, the amplitude and tonal quality (harmonic-to-noise ratio) show contrasting patterns: as arousal increased, the intensity also increased in screams, but n
