- 13:15 Dorothy Cheney & Robert Seyfarth: Signalers, receivers, and pragmatic inference in primate communication

Communication has been shaped by evolution. Signalers would not produce signals if doing so were not beneficial to them, and receivers would not respond if doing so were not beneficial to them. How do signals achieve these two, sometimes contradictory, objectives? Like many others, we argue that that communicative signals occur because social interactions are inherently uncertain, since the best strategy for one individual depends on what the other does, and vice versa. Signals are adaptive because, for both signaler and recipient, they reduce uncertainty by providing information. Learning and cognition thus underlie the function of communicative events. This constitutes a parallel with language, but there is also a striking difference: whereas language is based on a shared meaning between signaler and recipient, meaning in animal communication seems asymmetrical. A signaler’s meaning – to the extent that we can discern it -- is constrained by both a small signal repertoire and a limited ability to represent the mental state of the recipient, while meaning to the recipient is largely unconstrained and enormously enriched by contextual cues. Recent studies of forest monkeys, chimpanzees, and some new data on bonobos suggest that individuals in these species may overcome some of the limits on call production – and increase the symmetry between signaler and recipient -- by combining call types in predictable ways and engaging in vocal ‘conversations.’

Fairness in equity and sharing games: Accounting for cultural developmental differences

Speaker: Tara Callaghan (St Francis University, Antigonish, Canada)

I will present the findings from a series of recent studies conducted in collaboration with Warneken, Blake, McAuliffe and Corbit. In these studies we contrasted 4- to 15-year-old children’s aversion to inequity across 7 cultures and 3- to 8-year-olds' tendency to follow a parental model of sharing in 2 cultures. Very recent work demonstrating that prior collaboration positively impacts aversion to inequity in a sample that had previously not demonstrated inequity aversion will be shared, along with insights gained from an assessment of older child and adult norms in this setting. The implications of these, and other, cultural developmental findings for accounts of early prosocial development will be discussed.
