“…However, both the claim that the language production system is designed to be communicatively effi cient, and the notion that this in turn can account for typological patterns, only goes through in so far as it can be demonstrated that, across languages, speakers' on-line production choices are regulated by communicative effi ciency. As with psychological research more generally (Henrich, Heine, & Norenzayan, 2010 ), research on speaker preferences in production has been undertaken on only a handful of phenomena, and a handful of languages, chief among them English (for an overview, see Jaeger & Norcliff e, 2009 ). For information-theoretic approaches to language production in particular, the empirical base is further limited, since this work tends to require larger databases on the basis of which informativity can be estimated (Bell, Brenier, Gregory, Girand, & Jurafsky, 2009 ;Piantadosi et al, 2011 ;Resnik, 1996 ).…”
