Paper published at the Genetic and Evolutionary Computation Conference (GECCO 2014)
Check out the new interview for ‘El.lipse’, a scientific magazine, where Luc Steels exposes the experiences and the motivation that led him, two years ago, to work for the Institute of Evolutionary Biology (IBE) in Barcelona.
Empathy is an essential mechanism in human communication. For instance, when having lunch at the table, if we want salt we only need to point at the salt cellar and someone will hand it to us. However, it is not such a simple phenomenon when trying to understand its biological nature. Among the several approaches to the study of human empathy, learn how robots help us when trying to decipher this complex behaviour.
Grammatical agreement means that features associated with one linguistic unit (for example number or gender) become associated with another unit and then possibly overtly expressed, typically with morphological markers. It is one of the key mechanisms used in many languages to show that certain linguistic units within an utterance grammatically depend on each other. Agreement systems are puzzling because they can be highly complex in terms of what features they use and how they are expressed. Moreover, agreement systems have undergone considerable change in the historical evolution of languages. This article presents language game models with populations of agents in order to find out for what reasons and by what cultural processes and cognitive strategies agreement systems arise. It demonstrates that agreement systems are motivated by the need to minimize combinatorial search and semantic ambiguity, and it shows, for the first time, that once a population of agents adopts a strategy to invent, acquire and coordinate meaningful markers through social learning, linguistic self-organization leads to the spontaneous emergence and cultural transmission of an agreement system. The article also demonstrates how attested grammaticalization phenomena, such as phonetic reduction and conventionalized use of agreement markers, happens as a side effect of additional economizing principles, in particular minimization of articulatory effort and reduction of the marker inventory. More generally, the article illustrates a novel approach for studying how key features of human languages might emerge.
