Agent Based Modelling of Communication Costs: Why Information Can Be Free

  title={Agent Based Modelling of Communication Costs: Why Information Can Be Free},
  author={Ivana Cace and Joanna J. Bryson},
What purposes, other than facilitating the sharing of information, can language have served? First, it may not have evolved to serve any purpose at all. It is possible that language is just a side effect of the large human brain — a spandrel or exaptation — that only became useful later. If language is adaptive, this does not necessarily mean that it is adaptive for the purpose of communication. For example Dennett (1996) and Chomsky (1980) have stressed the utility of language in thinking… 
Sharing is not erring: Pseudo-reciprocity in collective search
Using simulations in both static and dynamic environments, it is shown that sharing information can lead to individual benefits through the mechanisms of pseudo-reciprocity, whereby shared information leads to by-product benefits for an individual without the need for explicit reciprocation.
Agent-Based Modeling
Agent-based modeling is a long-standing but underused method that allows researchers to simulate artificial worlds for hypothesis testing and theory building. Agent-based models (ABMs) offer
Representations underlying social learning and cultural evolution
This article discusses the potential computational properties of social learning, then examines the phenomenon in nature through creating a taxonomy of the representations that might underly it, and discusses theoretical limits on cultural evolution.
Embodiment versus memetics
The theory of memetics is linked to the established literature on semantic space, the extent to which these memetic mechanisms might account for language independently of embodiment is examined, and the evolution of language through uniquely human cognitive capacities is explained.
Agent-Based Modelling
ABM is still a sufficiently new research methodology that there is still some controversy in its use, and still some unevenness in its application and description in scientific papers.
Age-related inhibition and learning effects: Evidence from transitive performance
In the absence of sufficient cognitive stimulation, intelligence — and with it, a capacity for learning new things — tends to degrade with age. In this paper I explore a novel hypothesis: that this
Trust-based social mechanism to counter deceptive behaviour
This thesis provides a mechanism to support countering deceptive behaviour by enabling agents to model their agent environment, as well as their trust in the agents they interact with, while using the data they already gather during routine agent interactions.
Replicators, lineages, and interactors
It is shown that cultural evolution is necessarily a separate process from cultural group selection, and it is illustrated that the two processes may influence each other as demonstrated by an agent-based model of communicating food-processing skills.
Crude, Cheesy, Second-Rate Consciousness
If we aren’t sure what consciousness is, how can we be sure we haven’t already built it? In this article I speak from the perspective of someone who routinely builds small-scale machine intelligence.
Cultural ratcheting results primarily from semantic compression
This chapter attempts to clarify the problem of cultural accumulation by distinguishing between the site of a culture that can be transmitted from one generation, and the extent of culture transmitted.


Language and hominid politics
It is suggested that relevant speech originated in this context, as a way for individuals to select each other to form alliances, in the continuation of the 'chimpanzee politics' studied by de Waal (1982).
Evolving communication through the inference of meaning
This thesis develops a solution to the signal redundancy paradox based on the inference of meaning and the disambiguation of potential referents through exposure in multiple contexts, and describes computational models of meaning creation in which agents independently develop individual conceptual structures based on their own experiences of the environment.
Intelligent Meaning Creation in a Clumpy World Helps Communication
This article investigates the problem of how language learners decipher what words mean and demonstrates that an intelligent meaning creation strategy in a clumpy world leads to the highest level of meaning similarity between agents.
The Inferential Transmission of Language
It is demonstrated that the uncertainty inherent in the process of meaning inference leads to stable variation in both conceptual and lexical structure, providing evidence which helps to explain how language changes rapidly without losing communicability.
growing artificial societies : social science from the bottom up
How do social structures and group behaviors arise from the interaction of individuals? Growing Artificial Societies approaches this question with cutting-edge computer simulation techniques.

Formalizing a Language for Institutions and Norms
It is presented here a case for institutions in electronic trading, a specification language for institutions and its semantics and how this may be mapped into formal languages such as process algebra and various forms of logic, so that there is a framework within which norms can be stated and proven.
Towards the integration of social dominance and spatial structure
It is shown how individual-oriented (or artificial life) models may provide an integrative background for the development of theories about dominance by including effects of spatial structure in which the effects of winning and losing are self-reinforcing.
Complex Systems in Language Evolution: the Cultural Emergence of Compositional Structure
This work presents an Iterated Learning Model of the emergence of compositionality, a fundamental structural property of language, and shows that the poverty of the stimulus available to language learners leads to a pressure for linguistic structure.
Adaptive factors in the evolution of signaling systems
This book proposes to take a wider view, seeing human language as one among many animal communication systems, and focusing on the selective pressures affecting the origin and maintenance of such systems.
