Do egocentric biases contribute to reducing the collaborative effort in dialogue?
During dialogue, speakers attempt to facilitate their partners’ comprehension by producing partner-adapted utterances. To do so, they rely on their common ground, which consists in the knowledge that two partners share and are aware of sharing. Consulting the common ground is cognitively costly for the speaker, but doing so contributes to reducing the total amount of effort spent by both partners (speaker and listener) to reach mutual comprehension, or collaborative effort. In this presentation, I will develop the idea that this is true despite the fact that common ground use is subject to a number of egocentric biases, shedding light on the idea that egocentrism may contribute to dialogic collaboration – at least in some cases.
