Preferring paths with fewer community boundaries.
A. Graph representing the Towers of Hanoi task used in Solway et al. [8], experiment 4. Vertices represent game states, edges represent moves that transition between game states. The start and goal states (s, g) show an example of the kinds of tasks used in the experiment. Colored arrows denote the two shortest paths that could accomplish the given task, with the red path passing through two community boundaries and the green path passing through a single community boundary. B. Results from Solway et al. [8], experiment 4, showing that participants preferred the path with fewer communities, or equivalently, the path that crosses fewer community boundaries. Bar graph shows fraction of participants (35 participants). Dashed line is chance. C. Results from simulations showing that our model also exhibits the same preference. Bar graph shows the fraction of simulations that chose the path with fewer community boundaries. Error bar is s.e.m. (35 simulations).
