Imagine if language were a living organism, constantly evolving and changing over time. Well, that’s exactly what researchers are discovering through iterated learning models. In a fascinating case study, scientists used these models to investigate the historical change in the accent classes of two Korean dialects. The simulations showed that successive generations of phonotactic learning played a significant role in shaping these changes. By comparing different iterations of the learning models, researchers found that Korean learners’ phonotactic generalizations were influenced by storing entire syllable-sized units. Moreover, perceptual confusions between different forms had a substantial impact on the historical change of the accents. This study not only sheds light on how broad characteristics of language evolve but also provides insights into the intricate patterns of historical language change. It’s like unraveling the DNA of language! If you’re curious to delve deeper into the fascinating world of language evolution, check out the full article!
Abstract
Iterated learning models of language evolution have typically been used to study the emergence of language, rather than historical language change. We use iterated learning models to investigate historical change in the accent classes of two Korean dialects. Simulations reveal that many of the patterns of historical change can be explained as resulting from successive generations of phonotactic learning. Comparisons between different iterated learning models also suggest that Korean learners’ phonotactic generalizations are guided by storage of entire syllable-sized units, and provide evidence that perceptual confusions between different forms substantially impacted historical change. This suggests that in addition to accounting for the evolution of broad general characteristics of language, iterated learning models can also provide insight into more detailed patterns of historical language change.
