We report a cognitive modeling experiment where the RoboCup simulation environment was used to study the advantages provided by signals. We used the passing problem in RoboCup as our test problem and soccer-players’ ’yells’ of their ’passability’ values as the task-specific signals. We found that yells improve pass completion – using yells to decide the best player (to pass the ball) led to a 8-17 percentage points increase in performance compared to a centralized calculation of best pass. However, the passability values themselves did not make a difference, indicating that the advantage of signals come from their different perspective in identifying a pass, the actual content of signals do not matter. We present some problems we faced in using Robocup as a modeling environment, and suggest features that would help promote the use of RoboCup in cognitive modeling.
