Empirical research on human and non-human primates suggests that communication sounds express the intensity of an emotional state of a signaller. In the present study, we have examined communication sounds during induced social interactions of a monogamous mammal, the tree shrew. To signal their unwillingness to mate, female tree shrews show defensive(More)
Across mammalian species, comparable morphological and physiological constraints in the production of airborne vocalisations are suggested to lead to commonalities in the vocal conveyance of acoustic features to specific attributes of callers, such as arousal and individual identity. To explore this hypothesis we examined intra- and interindividual acoustic(More)
Shared acoustic cues in speech, music, and nonverbal emotional expressions were postulated to code for emotion quality and intensity favoring the hypothesis of a prehuman origin of affective prosody in human emotional communication. To explore this hypothesis, we examined in playback experiments using a habituation-dishabituation paradigm whether a solitary(More)
Sound categorisation plays a crucial role for processing ecological and social stimuli in a species' natural environment. To explore the discrimination and evaluation of sound stimuli in human babies and nonhuman primates, a reciprocal habituation-dishabituation paradigm has been successfully introduced into auditory research. We applied the reciprocal(More)
