    "abstract": "Lewis signaling game (LSG) and similar coordination \ngames have been used to model the emergence and\nevolution of language. However both Nash\nequilibria and learning or evolutionary\ndynamics often result in suboptimal signaling systems.  \nWe present a sequential reinforcement  \nlearning (SRL) model based on a novel sequential binary decision\nprocess. SRL has low cognitive demands and parameter\ncount and exhibits lateral inhibition without additional\nassumptions. \nWe prove all scenarios converge to an optimal signaling\nsystem in all N state, N signal LSGs with arbitrary\nstate probabilities and further\nexplore its properties with numerical simulations. \nNext, we model a signaling game with \nagents who both speak and hear while using \none state of learning (instead of two,  as is common).  \nAgents have a probability\ndistribution for meanings in a given context.\nSpeaking agents use the distribution to \nchoose a meaning and use SRL model to \nchoose a signal. \nHearing agents use Bayes to combine their state of learning\nwith their  meaning distribution to guess a meaning.\nAn agent's state of learning is reinforced\nfrom habit of speaking and guessing a meaning.\nNumerical simulations indicate both agents\nconverge to the same optimal system\nwithout external reinforcement\nas happens in language acquisition.",
