Division of cognitive labor and collective behavior

    Project: Research Project

    Project Details

    Description

    Group performance often benefits when members divide the group’s task into separate components and each member specializes their role so as to accomplish only one of the components. While this division of labor phenomenon has been observed with respect to both manual and cognitive labor, there is no clear understanding of the cognitive mechanisms that allow for its emergence. For example, maximization of expected utility often does not predict how individuals divide labor in one particular way rather than another. We have developed an iterative two-person game in which there are multiple ways of dividing labor, but in which it is not possible to explicitly negotiate a division. We implemented the game as a human experimental task and simulated a heuristic that is able to explain the observed behavior. Our results show that a priori salience of different divisions of labor is insufficient to account for their prevalence in interacting dyads. Instead, dyads frequently achieve efficient division of labor through simple but feedback-sensitive heuristics that systematically decrease the amount of overlap across the members’ roles.

    Layman's description

    The division of labor phenomenon has been observed with respect to both manual and cognitive labor, but there is no clear understanding of the intra- and inter-individual mechanisms allowing for its emergence, especially when there are multiple divisions possible and communication is limited. Situations fitting this description include individuals splitting a geographical region for resource harvesting without explicit negotiation, or a couple tacitly negotiating the hour of the day for each to shower so that there is sufficient hot water for both. We studied this phenomenon by means of an iterative two-person game in which different divisions are possible, but no explicit communication is allowed. Our results suggest that biases toward a priori divisions are revealed and consolidated through the dyadic interaction.
