We describe an extraction asymmetry in Moken that presents apparent Anti-Superiority effects. We then show that this asymmetry is not rooted in Superiority at all. Evidence from island effects is used to demonstrate that the left-dislocation of wh-phrases is not the result of wh-movement as standardly conceived. Furthermore, the same Anti-Superiority effect obtains for non-wh-phrases and clefts. At the same time, standard Superiority effects in Moken do arise in certain environments. These observations lead to the conclusion that Anti-Superiority effects in Moken are not counterexamples to...

Color naming reflects both perceptual structure and communicative need

Gibson et al. (2017) argued that color naming is shaped by patterns of communicative need. In support of this claim, they showed that color naming systems across languages support more precise communication about warm colors than cool colors, and that the objects we talk about tend to be warm-colored rather than cool-colored. Here, we present new analyses that alter this picture. We show that greater communicative precision for warm than for cool colors, and greater communicative need, may both be explained by perceptual structure. However, using an information-theoretic analysis, we also...

Efficient compression in color naming and its evolution

We derive a principled information-theoretic account of cross-language semantic variation. Specifically, we argue that languages efficiently compress ideas into words by optimizing the information bottleneck (IB) trade-off between the complexity and accuracy of the lexicon. We test this proposal in the domain of color naming and show that (i) color-naming systems across languages achieve near-optimal compression; (ii) small changes in a single trade-off parameter account to a large extent for observed cross-language variation; (...
