Examples of the sign systems studied by Galantucci et al. (2010). The signs are placed in the location on the game map they indicated. (A) Non-combinatorial system developed for the slowly fading medium. Each sign is composed of a distinct basic form. (B) Highly combinatorial system developed for the rapidly fading medium. Every sign contains at least one basic form that is present in one other sign. Forms are sequenced in time. (Adapted from Galantucci et al., 2010).
