of antiphonal calling in common marmosets. J. Comp. Physiol. A 198 (5),

Abstract: Many vocalizations are encoded with a diversity of acoustic
information about the signal producer. Amongst this information content are
social categories related to the identity of the caller that are important
for determining if and how a signal receiver may interact with that
individual. Here, we employed a novel playback method in common marmosets
(Callithrix jacchus) to test individual recognition during bouts of
antiphonal calling. These experiments utilized custom, interactive playback
software that effectively engaged subjects in antiphonal calling using
vocalizations produced by a single individual and presented ?probe?
vocalization stimuli representing a different individual at specific points
within bouts of calling. The aim here was to test whether marmosets would
recognize that the probe stimulus was a phee call produced by a different
individual. Data indicated that marmosets were able to detect the change in
caller identity; subjects produced significantly fewer antiphonal call
responses to probe than control stimuli and, in some conditions, exhibited a
shorter latency to produce the vocal response. These data suggest that
marmosets recognize the identity of the individual during bouts of
antiphonal calling. Furthermore, these results provide a methodological
foundation for implementing the probe playback procedure to examine a
broader range of social categorization during vocal interactions.
