Models of Artificial and Iterated Language Learning: Unravelling How Language and Languages Emerged
Although at the level of the language system human language is clearly unique and fundamentally different from all known animal communication systems, at the neural level and at the level of learning and processing mechanisms it is difficult to identify uniquely human components. This paradox might be resolved if we (i) find small but significant differences in some of these mechanisms, and (ii) show that such small differences can have observed major consequences. Much of the cross-species comparisons in Artificial Grammar Learning can be seen as addressing the first of these challenges. Computational models are being used to test predictions of how such mechanisms might operate. In my individual project I will review the findings in this area, in collaboration with the other team members, and further refine computational models that address both the first and the second of these challenges. The key insight here — from an approach known as ‘iterated learning’ — is that cultural evolution can kick in in a learned communication system that is transmitted culturally from generation to generation. This might shape the communication system to become much more complex and allow small differences in the learning and processing mechanisms to have large consequences. It thus provides an additional and novel window on the evolution of rule learning. In my project, and in the interactions with the other NLTG members, I will bring together empirical findings and modelling results from a variety of fields and start working on a book-length discussion of these issues.
