Social coordination in animal vocal interactions. Is there any evidence of turn-taking? The starling as an animal model.

Henry L, Craig AJ, Lemasson A, Hausberger M - Front Psychol (2015)

Bottom Line: Here we test the hypothesis that turn-taking and associated rules of conversations may be an adaptive response to the requirements of social life, by testing the applicability of turn-taking rules to an animal model, the European starling.These findings lead to solid bases of discussion on the evolution of communication rules in relation to social evolution.They will be discussed also in terms of processes, at the light of recent neurobiological findings.

ABSTRACT
Turn-taking in conversation appears to be a common feature in various human cultures and this universality raises questions about its biological basis and evolutionary trajectory. Functional convergence is a widespread phenomenon in evolution, revealing sometimes striking functional similarities between very distant species even though the mechanisms involved may be different. Studies on mammals (including non-human primates) and bird species with different levels of social coordination reveal that temporal and structural regularities in vocal interactions may depend on the species' social structure. Here we test the hypothesis that turn-taking and associated rules of conversations may be an adaptive response to the requirements of social life, by testing the applicability of turn-taking rules to an animal model, the European starling. Birdsong has for many decades been considered as one of the best models of human language and starling songs have been well described in terms of vocal production and perception. Starlings do have vocal interactions where alternating patterns predominate. Observational and experimental data on vocal interactions reveal that (1) there are indeed clear temporal and structural regularities, (2) the temporal and structural patterning is influenced by the immediate social context, the general social situation, the individual history, and the internal state of the emitter. Comparison of phylogenetically close species of Sturnids reveals that the alternating pattern of vocal interactions varies greatly according to the species' social structure, suggesting that interactional regularities may have evolved together with social systems. These findings lead to solid bases of discussion on the evolution of communication rules in relation to social evolution. They will be discussed also in terms of processes, at the light of recent neurobiological findings.

Figure 11: Song sequence duration and sequence interval duration for the 4 species of African sturnids.

Mentions: Interestingly, this gradient corresponded to the increase in the complexity of social life (Figure 11): the more the species showed a complex and especially family type of social organization (in terms of number of congeners and nest proximity), the more their songs were produced in a continuous manner. In the same way, for species that produced continuous song, the phrase durations and the number of motifs per phrase increased following the same gradient (ANOVA, F = 5.51, df = 2, p < 0.0001; F = 89.82, df = 2, p < 0.0001 respectively).
