Turn-taking is fundamental to human conversation, so the question of whether it occurs in other social animals is extremely interesting. A new paper on turn-taking in marmoset monkeys (Takahashi et al., "Coupled Oscillator Dynamics of Vocal Turn-Taking in Monkeys", Current Biology, 2013) is to be applauded for tackling this issue.
Unfortunately, though, it is not clear that their data demonstrate turn-taking in any sophisticated sense: specifically (and this is the sense embraced by the authors), entrainment of timing mechanisms between two individuals to regulate the passing of the turn. They begin by asking, "Is this a simple call-and-response (‘‘antiphonal’’) behavior seen in numerous species, or is it a sustained temporal coordination of vocal exchanges as in human conversation?" They conclude that they have shown the latter, but, on my reading, all their data is compatible with simple call-and-response. What seems to be going on is that the authors have failed to appreciate just how weird human turn-taking is. Read the rest of this entry »
