> Abstract
>
> Numerous studies indicate that the human brain may contain neural
> specializations for music processing (e.g., Peretz 1996, Johnsrude et al.
> 2000, Perry et al. 1999). This, in turn, suggests that there may be
> psychological adaptations for producing and processing music. If so, what
> function or functions did music serve in ancestral human environments? A
> variety of possible functions have been proposed, the most prominent
> being that music either promoted 'social cohesion' (e.g., Roederer 1984),
> or signaled mate quality (e.g., Darwin 1871, Miller 2000, Werner and Todd
> 1997). We propose, instead, that synchronization and variation, two
> universal features of music (and dance), are ideally suited to credibly
> signal coalition quality, a function that would have been critically
> important during alliance formation and war. Here we present the results
> of a small pilot study which supported this hypothesis. Subjects'
> perceptions of music quality were significantly correlated with their
> perceptions of coalition quality. A manipulation of music quality along a
> theoretically significant dimension was also significantly correlated
> with perceptions of coalition quality.
