Exploiting individual differences to bootstrap communication

The emergence of communication systems has long been a subject of interest, with traditional theories emphasizing the role of feedback in reinforcing successful communication behaviors. However, a recent model suggests that communication can arise from individual behavioral differences within a population, independent of pre-existing communicative frameworks. This model identifies two cognitive capabilities as crucial: the ability to behave predictably in specific situations and the alignment of psychological states through shared intentionality. These insights not only challenge existing paradigms but also align with broader theories of social cognition, suggesting that flexible, socially-learned communication systems can evolve from non-communicative behaviors. This research opens new avenues for understanding how communication might develop in various contexts, potentially influencing fields such as artificial intelligence and social dynamics.
